The Chu State defeated the world with fish and rice, which is to say that compared with other countries of this era, rice that has ripened twice a year has appeared in some important counties. Although the taste is not very good, for the old Qin soldiers who are used to eating corn, it is also very good to change the taste occasionally.

The young master held a big bowl of rice with an old bowl of rice in his hand, and a large piece of fat meat and a few rosies of autumn sprouts were placed on the rice. He ate a few bites of rice and took a bite of fat meat. He ate the fat meat and was muttering that he couldn't say clearly: "I said, brother Bai family, this time you must promise me to give me 30,000 people. I promise to take Changping in half a month, or just seven days? Please, I have been studying arithmetic every day in the academy for these days, and my head is about to explode. I finally got a war. I must give this lead!"

"You can take the lead, but Che Yingzi'an and the others were thinking. Your elder brother came to my military camp last night and said he wanted to personally win Changping. I really don't know what you are thinking about. Changping is an important town in the southern part of Wei State, an important port connecting the Binshui and Yingshui. There are 8,000 heavy armed soldiers in the city, 2,000 troops stationed, 2,000 naval troops, and the city is strong, easy to defend but difficult to attack. You can take it down with 30,000 people? Do I want me to pull all the 150,000 troops under Changping City, just like Pang Juan besieged Handan, and set up a formation for several months?"

"That's satisfying."

"You are satisfied, the army will be killed alive! So this time when we attack Wei, the first thing we need to do is not to capture the city, but to kill the enemy!"

"I don't understand anymore. How can I kill the enemy without siege? If Changping doesn't take it down, we can't move forward. The Wei army will cut off our retreat. The army will be trapped in a heavy siege!"

"Severe our retreat. What about the Wei army? I'm just afraid they won't come..."

Bai Dong smiled slightly. He took the rice bowl from the flea, hurriedly pulled it up, jumped up and said, "Let's go, follow me to Ou Yeliang's place to take a look..."

One month after the army was trained in Shangyu, Bai Dong received a reply from the King of Chu. The King of Chu was so happy that he heard that the Qin army wanted to attack Wei by using Chu State. This was the case during the Warring States Period. The princes of all countries had the same idea and wanted other countries to fight as fiercely as possible. Moreover, the situation of Chu State was very special, and they bordered Qin, Han, Wei, Song, Lu, and Yue. Naturally, there must be many frictions. Now, the increasingly powerful Qin State is going to challenge the overlord of Wei State, and the King of Chu was happy to have a banquet for the ministers.

If you watch the fun, you don’t have to make a big deal. If you should make a fuss, you have to make a fuss. In addition, the relationship between Chu and Qin has always been good, so the King of Chu put a lot of effort into accepting the Qin army. Not only did he vigorously block the news, but he also prepared a large number of Chu armored flags for the Qin army. As soon as the Qin army entered Chu Pass, he immediately changed his clothes. Not to mention that the spies of Wei were not as good as this, even the troops stationed by Chu may not be able to distinguish them. He was so hard that he could only go so hard to get the same. He could secretly and safely cross the Chu territory and then beat the old Wei people!

He was quite confident in Baidong, Handan. In the Warring States period, he also had strong soldiers and strong cities. How could a capital like Linzi like Handan be broken by saying that could be broken? Even Pang Juan was the same. So he was not in a hurry. After the army arrived at the shore of Yingshui, he set up camp to let the soldiers rest and rest. He replenished his body with big fish and meat every day. He called Ou Yeliang and made a drawing to explain the things in the picture. After explaining the things in the picture, Ou Yeliang's eyes widened, as if he wanted to see through Bai Dong: "Bai Zi knows that this thing is not conducive to confidentiality. Once it is used on the battlefield, the people of Wei will know it? Do you know how many changes it will cause once this thing comes out?"

"There is no question of a change. Once this thing comes out, it will greatly reduce transportation costs, the economy will be stimulated, and business will develop more. Now the Bai family trading company is enough to rank among the top three in the world's trading company. The biggest benefit belongs to us. As for the people of Wei, they will not care. This battle has a great impact on Qin. If this battle is won, Qin will become stronger. The power of Wei will be defeated in ten years, so I am not afraid of them knowing this secret."

Bai Dong smiled slightly: "But it is not easy to learn from me. This thing seems simple. If it is cast in bronze, it will lose its toughness. If it is cast in iron but not hard enough, even if the Wei people made it, just by frequently changing the energy and money spent on them can make them worry. Therefore, this thing also needs a special metal to cast."

"You are finally willing to tell the secret. Tell me quickly, what kind of special metal is it?"

So Bai Dong is not afraid that Ou Yeliang will betray Lao Qin. This guy can get a dead man's corpse and sword. It can be seen that he is a technical madman. When dealing with such a technical madman, money, beauty and national honors are all nonsense. Only brand new technology can make him fascinated and then drive him away.

Ou Yeliang is now the big palm furnace of the military rank of the Old Qin. Since this guy plunged into the Ordnance Department, he has been asking Lao Qin for a hundred and a thousand years of iron mother every day, which has caused Ying Quliang to have a headache. In fact, the so-called iron mother is just a piece of iron smelting with high purity and easy decarbonization. It is not as crunchy as ordinary pieces of iron smelting and cast iron. It is used as a farm tool, and it will be hunted by the army if it is used as a weapon. But in this era when the method of stir-frying steel has not even been invented, once the "Iron Mother" with high purity falls into the hands of people like Ou Yeliang, it can turn it into a metal close to "steel" through various means and cast magic weapons. How can there be many such good things? Who can bear it if you ask for it like rice and wheat all day long?

In the end, Bai Dong came forward and coaxed Ou Yeliang to the army and promised him that he had a new method of refining, which could get unprecedented metal. This guy was willing to follow him. He tangled Bai Dong for a long time when he was in Shangyu Mountain, and now he finally got what he wanted.

When the young master followed Bai Dong to Ou Yeliang's territory, he saw that Gongzi Qian and others were also there from a distance, as if he had been waiting for a long time. When everyone saw Bai Dong coming, they smiled and said, "Why did the General come? Mo Shi and Ou Ye's palm furnace are there, saying that they are waiting for you to open the furnace..."

When he walked into Ou Yeliang's sword hut, he immediately felt the heat rushing to the face. Bai Dong took off his robe and threw it to the old army of the Bai family who came with him, and smiled and said, "I knew they would have friction. Let's go and have a look. Didn't the eldest son ask me yesterday what I want to win over the Wei people? The answer lies in this sword hut."

Now Ou Yeliang’s sword hut is actually a big refining workshop. It doesn’t matter whether he can refine a magic weapon that is comparable to Gan Jiang Moye. The big palm furnace is now concerned about new metals.

During the Spring and Autumn Period and the Warring States Period, although there were occasional "Iron Mother" with higher purity, even the most primitive low-carbon steel did not appear. Even masters like Ou Yeliang always had to worry about the materials. Once they got the iron Mother with low carbon content, they would use human bones and animal bones to complete the original carburization process. No matter how you look, they looked like a crazy man who had been refining a sword until he was in a devilish way.

Bai Dong's so-called new metal actually originated from primitive iron ore, but in order to obtain iron with lower carbon content or even low carbon steel and medium carbon steel, it must be taken out the "steel-frying method" that was invented until the Western Han Dynasty. Once this method was released, a hundred or thousand-year-old iron mother became a joke. No matter how good the iron is, it is not as good as a piece of low carbon steel, not to mention that by using carbon as a reducing agent, the carbon in the steel is carbon dioxide or carbon monoxide. The Qin army attacked Wei Tu with only 150,000 people. The first thing to do is to ensure that once there is a horseshoe, a large-scale mobile warfare becomes possible. In addition, to deal with Wei Wuzhang, strong bows and hard crossbows and sharper arrows are also indispensable. It is said that the "steel-frying method" is the key to winning the Wei people, and there is no mistake at all.

"Open the furnace!"

When he saw Bai Dong coming, Ou Yeliang roared and the main furnace immediately burned. Countless iron ore was put into the center to make a pot, and gradually softened and melted. The method of steel frying was invented in the Western Han Dynasty, but Europe was lagging behind for more than a thousand years. The reason was the temperature of the furnace. Because of the development of ceramic technology in China, it was not difficult to achieve the steel frying of 1,200 degrees, and any porcelain kiln could do it. Europeans were different. Until the medieval castles were piled with big stones, and civilians still lived in wooden houses because they did not know the technique of firing bricks at all. When they saw porcelain from the East, the nobles and men were all taking a porcelain urinal all day to show off. It is precisely because of this background that Bai Dong’s move out the steel frying method of the Western Han Dynasty was not a shocking thing.

The iron containing a lot of impurities gradually boiled. The ink thread standing in front of the furnace tried the fire and shouted: "Fry!"

Several stone sticks were immediately stretched out on the beam hanging above the pot, and they started to stir clockwise in the molten iron by pulling the rope. At the same time, some craftsmen also began to pull the bellows and used wind guns to blow the molten iron. Soon they saw a mass of stains appearing on the boiling molten iron surface, and it was the impurities in some ores that were frying out.

Even Ou Yeliang admired the ability to see fire in the ink line. He patted his shoulder and Ou Yeliang ordered people to pour the fried iron into the mold. The iron clusters of arrows quickly formed. While the iron clusters had not cooled down and became hard, Ou Yeliang personally picked up one with tongs, grabbed a pinch of bone powder from the material bag and evenly sprinkled on the iron cluster, then heated it back and forged it red, and repeatedly used a hammer to forge it several times, and finally put it in cold water and took it out. When everyone walked in and saw that the iron cluster was black and blue, and there seemed to be cloud patterns on the surface. It was a strange phenomenon that only magic weapons like Gan Jiang Moye had.

Bai Dong smiled and said, "Come on, the wooden man who is testing the arrow is wearing three layers of heavy armor. All of them are the best bamboo and copper armor. I want to test the arrow!"

The wooden man wearing three layers of heavy armor was quickly placed fifty steps away from everyone. The cluster of arrows created by Ou Yeliang was also placed on the tip of the arrow. After being loaded into the powerful crossbow made by the Gongshu, an ordinary soldier was asked to fire with the crossbow. Only a few '** wave' sounds were heard. The arrow broke through the three layers of heavy armor and shot the wooden man into the opposite direction!

Gongzi Qian and Che Yingzi'an and other old men in the army walked over and looked again and again. They were all excited and laughed: "So this is the key to winning the Wei Kingdom? The General is a real god!" Although this arrow was not refined by Bai Dong himself, when everyone knew that it must be Bai Dong's method when looking at Ou Yeliang's expression.

Bai Dong smiled and shook his head: "Although this thing is good, it is not the key to defeating the Wei people... Ouye Da Palm Furnace, and starts to refine 'horsehound'. This thing just fry and smeltek juice, and there is no need to be as troublesome as refining arrow clusters." (To be continued, please search Piaotianwen, the novel is better and faster!
