In fact, what Xiang Kang was most concerned about was not his own kingship, but the internal problems that were piled up in the control of the young commander army.

After entrusting Liu Laosan with the blessing of force, after forcefully forcing the Qin court to surrender, only eight days later, the Young Marshal's Army faced the danger of a full-scale battle with the coalition forces of the princes outside the pass, and had to give priority to military preparations. Xiang Kang himself was forced to leave the command center Xianyang City, and led the main force of the Young Marshal's Army to Hangu Pass to respond to the threat of the coalition forces of the princes. It was not too late to win over the hearts of the Qin people and establish a new Guanzhong regime, let alone restore the economy and people's livelihood, clean up the accumulated traits of the previous dynasty, develop science and technology education, and apply Xiang Kang's later knowledge to the production and construction of this era.

The consequences of this are of course that various internal affairs were severely delayed. In more than a month after leaving Xianyang, Xiang Kangling was unable to handle a specific internal affairs, economy, personnel, criminal law, water conservancy, farming, grain distribution and material supply, and other rear affairs, all of which could only be entrusted to Zhou Zeng, who was forcibly tied to the anti-Qin chariot by Xiang Kang, to recruit new recruits, form new troops, manage local areas and prevent rebellions, and other public security preparations, and could only be handed over to Chao Zhi, the former Qin army county magistrate. If you are not careful, there will be a risk of a fire in the rear at any time.

Fortunately, neither Zhou Zeng nor Chao Zhi disappointed Xiang Kang. During his stay in Xianyang, Zhou Zeng, who was good at civil affairs, did not have any dazzling political achievements, at least handled internal affairs in an orderly manner and never made any major mistakes. Chao Zhi also worked hard to do his job well. In a short time, he urgently recruited 20,000 new recruits for Xiang Kang and went to the front line of the Yellow River, helping Uncle Zhou block the fierce Zhao army's troops of Shenyang, and did not give Shen Yang the opportunity to take advantage of the situation to enter the hinterland of Guanzhong. During this period, some surrendered officials in Xianyang who were still loyal to the Qin court tried to take advantage of the chaos, but Chao Zhi immediately suppressed the danger, stifled the danger in the bud, and together with Zhou Zeng, he made great contributions to stabilize the rear for Xiang Kang.

But Xiang Kang was not satisfied with this. He just confirmed that the coalition of princes disbanded on his own and on his way to Xianyang from Hangu Pass, Xiang Kang could not wait to prepare for the development and reform plan of the land controlled by the Young Marshals Army, and regarded the already prosperous Guanzhong Plain as its rear construction to lay the economic, material and manpower foundation for the next step of unifying the world.

Time was rushed, and the world-class feudal system that my cousin Xiang Yu had made was obviously trying to surround the Shaomai army. The princes outside the pass, whose fief was controlled by the Shaomai army, were already ready to fight to fight against the Shaomai army. Of course, Xiang Kang could not reform the political system on a large scale. He could only temporarily continue the system of the Three Dukes and Nine Ministers left by the Qin court, and then reform it to a more advanced three provinces and six ministries system when the time is ripe. Therefore, Xiang Kang did not bother too much in the political system, and devoted his main energy to the most important aspects of the development of farming technology and military technology.

How to develop farming and military technology? As early as Huaisi, Xiang Kang had actually made many plans, and went deep into the front line of production and construction more than once to understand the farming situation in this era, and study how to improve the currently lagging farming technology with the fastest time and least manpower and material resources. However, Xiang Kang was busy with military affairs almost every day at that time, and Xiang Liang might reach out to seize power at any time. The Huaisi area, which is without danger, is not suitable to become a reliable and stable rear. Xiang Kang never puts it into practice. He just kept some of his own ideas in his heart and prepared for it in the future.

Now Xiang Kang can finally show his skills. He just returned to Ningqin with the main force of the Young Marshal Army. Xiang Kang had already decided how to develop farming and expand grain production. First, he was preparing to get out the iron hoe, second, he implemented the field replacement method to reduce the time of land waste, third, he improved the plowing plow, replaced the primitive plows that were still very backward in this era, and more primitive plow farming techniques.

It is the easiest to get iron hoes. There were stone hoes in this era, but because of the brittle bronze nature, it could not be cast, and the iron smelting technology was very backward. So there was no iron hoes until now. When I was in Huai Si, Xiang Kang had already developed the smelting technology of land steel. He just used the smelting steel to build a hoe. There was no need for Xiang Kang to do it at all. He could do it by simply finding some skilled blacksmiths. However, after using iron hoes to replace the stone hoes from the Stone Age, the efficiency of farming production and civil engineering can definitely reach a big step.

The field generation method is the farming technique that Xiang Kang learned in the TV popular science program, and it is also a simple and huge progress in farming technology. In this era, because the farming technology is too backward, farmers directly turn over the land and sow seeds. The grain yield is small and the land consumption is large. In order to restore the fertility of the land, it usually takes one year to fallow after one farming, and some relatively barren land even takes two years to fallow.

The method of field generation is different. The land is tilled into two shapes: ridges and ditches, and the ridges and ditches are arranged side by side. In the first year, the seeds are sown into the ditch to obtain enough water to grow strongly. When the ridge soil is flattened in summer, the ridge soil is used to strengthen the roots of the crops, which can resist drought and wind, and reduce crop lodging. In the second year after harvest, the ridges are plowed into ditches and the ditches are built into ridges. Continue to sow seeds in the ditch. This repetition can allow the same piece of land to take turns to rest, not delay farming production, but also restore land fertility. If well operated, the grain output of one acre of land for two years can be equivalent to the grain output of two acres of land for two years in this era.

Plowing must also be reformed. There were too few oxen in this era. Only the nobles and rich people had oxen at home. The ploughing tools were still very heavy and primitive, and the efficiency of arable land was extremely low. Most ordinary families could only use more primitive plows to turn over the land and cultivate them, and the efficiency of farming was even lower. Only by inventing the plows that appeared in later generations in advance can the 800-mile fertile soil in Guanzhong provide Xiang Kang with military rations for killing and setting fires.

Originally, Xiang Kang, who was a city man before traveling, had no idea how to improve the plowing tools, but it was a coincidence that before traveling, Xiang Kang often went to a farmhouse where he fooled with his friends, and even placed various farm tools to decorate and attract customers. Among them, there were not only the curved plows that were invented by the Tang Dynasty, but also the human plows and foot plows that did not require plowing oxen. He also used words to explain the purpose and name, which left a deep impression on Xiang Kang, who was ignorant and solved the problems that Xiang Kang was currently facing.

Xiang Kang's memory is not bad. After trying hard to recall, on the night when he was resting outside Ningqin City, Xiang Kang relied on his memory to draw the specific shapes of the curved plow, the human plow and the foot plow on three pieces of silk, and marked the approximate size he had estimated. The rest only needs to make the real thing according to the drawing, and then through continuous experiments and improvements, it is definitely not a big problem to create these three advanced plows.

The human heart is not enough and the snake swallows the elephant. After the three plow sketches were completed, Xiang Kang threw down his brush and rubbed his sore wrist and saw the wasted silk all over the floor. He suddenly felt aroused and said to himself: "Do you want to make the paper too? It will save me a lot of money, so you don't have to wipe your butt with leaves in the future?"

This idea made Xiang Kang hesitate because no matter how poor Xiang Kang's history is, he knows who invented the practical paper. He stole the credit of Eunuch Cai. If he ended up like that of Eunuch Cai, it would be a terrible thing? As a result, just when Xiang Kang was a little confused, the captain Xu Ji suddenly carried a plate of food into the tent and said to Xiang Kang: "General Right, you have breakfast."

"Eat breakfast?" Xiang Kang couldn't believe his ears and asked in surprise: "It's already dawn?"

"It's dawn." Xu Ji said with a wry smile: "General Right, you should pay attention to your rest, why didn't you sleep all night?"

It was still necessary for Xu Ji to remind me that Xiang Kang realized that the sky outside the tent was already bright and he had not slept for a night without knowing it. He also smiled bitterly: "You have to pay attention. If I do this again in the future, remember to remind me, don't exhaust me."

Xu Ji was shaking by Xiang Kang's words, and didn't say anything. He just put the breakfast in front of Xiang Kang. As a result, he happened to eat steamed wheat rice this morning. Before Xiang Kang picked up the chopsticks, he remembered a big thing again. He couldn't help but blurt out: "You must also invent the stone mill and grind the flour with the army. This can save cooking time and facilitate digestion and absorption. You can also make some buns, steamed buns, pancakes, dumplings to improve food, and you don't have to just eat dry food like yellow rice balls."

In fact, this era has already had the prototype of stone mills, but they are as primitive and backward as the farming tools of this era, bulky and huge, and cannot be transported at all. They are only used to grind water and have never been used to grind noodles. Before, when Xiang Kang was in Huai Si, he mainly ate rice, but did not notice this problem. When he entered Guanzhong and ate wheat rice like the Qin army, Xiang Kang realized that he had to invent the stone mills and flour. This reminded him again, and flour products were easy to carry, preserve, digest and absorb.

It is precisely because of this that after rushing to eat the simple breakfast and taking the army to continue back to Xianyang, Xiang Kang couldn't wait to draw a stone mill in the carriage - entrusting Qin Shihuang's blessing to make the road on the plain spacious and flat. Although he could not draw any precise pictures while sitting in the carriage, he had no problem drawing simple sketches.

Of course, stone mills are simpler than plowing. Xiang Kang had also seen them many times in a farmhouse before traveling through time. He also knew that grinding teeth had to be radiant to grind even flour. He just sat in a carriage and just now, Xiang Kang drew a similar sketch of stone mill. He also smiled at the sketch with his head and couldn't wait to reminisce about the long-lost buns, steamed buns, fritters, dumplings and wontons, as well as ramen cut noodles, cut noodles with knife, and pie pancakes.

Seeing that Xiang Kang was both stupid and cheap, Zhang Liang, who was riding a horse, couldn't help but ask Xiang Kang why he smirked. Xiang Kang didn't hide it, and immediately gave Zhang Liang a detailed introduction to the stone mill sketch, and also mentioned the main purpose. Zhang Liang was very surprised after hearing this and said, "Right General, it's so delicious. Why do you suddenly want to use this stone mill to grind the wheat into powder? Just eat wheat rice and porridge directly, why do you have to do this in one go?"

"Mr. Zifang, after you have eaten good things made of wheat noodles, you will never go back to eat wheat rice and porridge." Xiang Kang said with a smile: "When the first batch of wheat noodles are ground, I will make you a meat bun with my own hands, so that you can eat it so much that you want to swallow it."

"It's really that delicious?" Zhang Liang obviously disbelief. After hesitating for a while, Zhang Liang also said: "Right General, don't blame the foreign minister for being indifferent. The article "Han Feizi" is a vocal chopstick and Jizi is a horror. I believe you have read it. Now the world is not yet determined, and the princes outside the pass are still looking at Guanzhong. If you only want to enjoy delicious food, you are afraid..."

"Don't worry, Mr. Zifang, I understand what you want to say." Xiang Kang hurriedly interrupted Zhang Liang's preaching and said, "I want to make flour, but in fact I'm more concerned about our military soldiers. Cooking with wheat noodles is not only faster, but also saves our soldiers' cooking time, but also fills our hunger and resistant to hunger than staple foods such as rice, bean soup and millet rice. In the morning, as long as you eat a meal made of wheat noodles, you won't feel hungry even in the afternoon, and it's easy to carry and preserve, reducing our logistics burden, so I attach so much importance to this stone mill."

Seeing that Xiang Kang was serious, Zhang Liang stopped talking and stuffing Xiang Kang. He just nodded with a smile, indicating that he believed in Xiang Kang. He twisted his body a few uncomfortable times and said with a wry smile: "It's still not possible. It's so uncomfortable after riding for a long time. It seems that the foreign minister will not be able to learn riding well in this life. The right general forgives the crime, and the foreign minister has to go back to the car and sit down."

Xiang Kang knew that Zhang Liang was in poor health and knew that riding on the horse was not good. Of course, Xiang Kang nodded immediately, but at the same time Zhang Liang left, a question also emerged in Xiang Kang's mind, "Do you want to invent the Gaoqiao saddle and stirrup?"

After reclining on the carriage for a long time, Xiang Kang still gave up the idea of ​​immediately inventing the Gaoqiao saddle and stirrup, because Xiang Kang knew very well that if the Gaoqiao saddle and stirrup were invented, the combat effectiveness of the cavalry of his own army would be able to be improved by a large margin immediately. It would be no problem for cavalry to sweep the princes outside the pass, but once these two horse harnesses were spread to the nomadic peoples in the north, it would likely cause a catastrophe to the Han people in the Central Plains!

Qin Shihuang had only been reunited for more than ten years. After several years of war, the people of the Central Plains had already sharply reduced their populations and their overall national strength had declined seriously. Even if Xiang Kang believed that he could ultimately unify the world, he would not guarantee how much time it would take to do this. He didn't know how many casualties and injured the people of the Central Plains would have to be killed or injured in the war to unify the world. He knew that if he wanted temporary benefits, he invented the Gaoqiao saddle and stirrup that changed the cavalry battle mode in advance and spread it to the nomadic people represented by the Huns in the north. The nomadic people took advantage of the opportunity of China's national strength to move southward, and the tragedy of the Five Barbarians invading China in advance was definitely not impossible!

So considering this, Xiang Kang could only silently say in his heart: "Let's talk about it later. When I unify the world, restore national strength, and allow the Central Plains cavalry to reach at least one-third of the Hun cavalry, and then invent the saddle and stirrup, I will be sure to kill all the jackals on the grassland once and for all. Or, it's okay to leave this matter to my children and grandchildren. In short, we can't throw watermelons for sesame seeds and make the barbarians in the grassland in vain."

After giving up this idea, Xiang Kang suddenly remembered what Xiang Yu had said in front of him, regretting that the sabre he gave him was not suitable for cavalry battles, and his cavalry did not have the weapon to join hands. Then Xiang Kang had just thought for a moment and soon drew a sabre with curves and handguards on the carriage, marked the approximate size he had estimated, and put it together with the farm tool drawings he drew last night, just waiting to go back to try to cast or build them.

In order to fundamentally greatly improve the combat effectiveness of the Young Marshal Army, it is of course far from enough to have a sabre, hook and sabre. While heading west, Xiang Kang was still racking his brains to recall what advanced weapons could be developed in advance. Then, naturally, the gunpowder that had been with the four major inventions naturally jumped out of Xiang Kang's mind.

"Is it necessary to get the gunpowder out in advance? This thing is easier to control, the formula is easy to keep confidential, and even if it is leaked, it is difficult to imitate the nomadic cavalry in the north without raw materials. But what's the use of getting the gunpowder out? With the productivity and production technology of this era, can I build muskets and cannons?"

"Wait, it should still be useful. Even if I can't make muskets and cannons, I put the gunpowder in a bottle and make it into primitive grenades. It can still get a lot of effect on the battlefield. At least it can scare the enemy half to death. It will definitely be effective to disrupt the enemy's battle formation. In addition, it can also be used as incendiary bullets. In addition, it should not be difficult to spray rockets. The formation will also surprise the enemy during wartime, and it will accumulate enough technology in advance. It is not impossible to appear muskets and cannons in advance in a few hundred years."

After thinking about this, Xiang Kang wrote the words "One nitr, disulfide, three charcoal" on the silk, and marked that this was just a general formula, and the specific ingredients ratio could be adjusted and changed through repeated experiments, and also marked that the hemp leads must be kneaded with nitrate powder.

Then, after roughly drawing a sketch of fish scale armor on the silk, and after drawing an iron helmet with a protective face, Xiang Kang, who had not slept for a night last night, fell asleep on the carriage, and was still smiling in his sleep. I don’t know if he dreamed of the seventy-two concubines of the Three Palaces and Six Courtyards, or if he dreamed of ten and eight peerless beauties who were not dressed. In short, he slept very sweetly.

The light-fitting army was very fast. On the afternoon of the next day, the main force of the Young Marshal Army, led by Xiang Kang, returned to the Hongmen Camp near Xianyang. Zhou Zeng and Chao Zhi, who had already received the news, also lined up with the officials of Xianyang to welcome Xiang Kang to return with the Hongmen. There were countless people in Guanzhong who came spontaneously. When Xiang Kang got off the carriage, the officials of Xianyang and the people of Guanzhong were not only bowing to the ground to salute together, but also shouted in unison: "Congratulations to the King for returning with triumphant success! Congratulations to the King for returning with triumphant success!"

"Uncle Ya, what do you mean?" Zhou Zeng, who came up to greet him with a smile, asked, "Why did you start calling that before the throne ceremony was officially held?"

"The Right General, the conscience of heaven and earth is really not arranged by the officials." Zhou Zeng shouted injustice and said, "It was they who wanted to call him that, and the officials did not make any arrangements."

After saying that, Zhou Zeng smiled and said, "But please forgive me for your crime. In order to save time, the subordinate officials have already started to do something. They have built a loess high altar for you on the banks of the Weishui River, and sent someone to rush to repair the Xiang Clan Ancestral Hall so that the Right General can ascend the throne at any time."

Xiang Kang smiled helplessly and said, "It's better to follow the rules. Starting tomorrow, I will fast in the military camp for five days. After five days, I will worship my ancestors first, and then ascend to the altar to be the king. Are you ready for the banner? Remember, it's the word "Chinese"!"

"Abide by the orders of the King of Han!" Zhou Zeng bowed his hand and took the lead in bowing to Xiang Kang on both knees, and said loudly: "Long live the King of Han!"

"Long live the King of Han!" The young commander and civil and military officers next to him knelt on the ground and shouted neatly.

"Long live the King of Han!" The people on the road knelt down again, and their neat voices were like a tsunami of landslides, "Long live the King of Han! Long live the King of Han!"
Chapter completed!
