Li Chengqian's greeting caused quite a response.

The ancients attached great importance to etiquette, filial piety and brotherhood. As the crown prince of the Tang Dynasty, the emperor in the future could put down his figure and salute an elder who was younger than him, which immediately added a lot of impressions to the people around him.

Sometimes it is like this. No matter how much or good you do in your daily life, you will not be praised. Some people just do something insignificant and will magnify infinitely.

Li Chengqian, who has his own crown prince halo, is such a person.

Yuan Ling knew that he was acting in concert: "The prince is so bad that I am. You are the prince and the future monarch, how dare you receive this great gift?"

If it were other emperors, Yuan Ling would have been a taboo in this way. Li Shimin was the opposite, and he liked to listen to this. In his eyes, Li Chengqian was the future emperor of the Tang Dynasty, and there was no dispute over the crown prince. He prefers King Li Tai of Wei for no reason, just because Li Tai was the son of Empress Changsun and his legitimate son, that's all.

Li Shimin was very satisfied with Li Chengqian's performance. As the future emperor, he must have a broad mind and said, "Okay, we are all family members, and we don't pay attention to these things. Take the lead quickly, so that I and my dear friends can also open my horizons. Is it really so magical that there is no need for manpower?"

Yuan Ling made a direct invitation gesture and said, "Your Majesty, Prince, and all the ministers, please!"

When I arrived at the side courtyard, the huge car came into my eyes.

No one operates it. Under the operation of hydropower, the sound of gears rubbing against each other and the sound of clamoring water flow gather together.

Even though Li Shimin, Changsun Wuji, Fang Xuanling, Wei Zheng and others had already seen the drawings, they couldn't help but exclaim when they saw the real thing with their own eyes.

"this……"

The most exciting thing was the middle-aged man who was about forty years old. He couldn't help but jump over Li Shimin. Li Chengqian stepped forward to watch and carefully checked every structure of the tube truck.

Yuan Ling looked at the details that the other party was paying attention to and knew that this middle-aged man was a real expert.

"Congratulations to Your Majesty, congratulations to Your Majesty!"

The middle-aged man shouted and said excitedly: "The conception of this trolley is really exquisite, but it is even more wonderful in a simple way. There is no profound and difficult to imitate. As long as there are detailed drawings, you can easily find a carpenter with more than ten years of expertise to make it, which can be fully popularized throughout the world. But..." He said, bowing to Yuan Ling and said: "The real useful thing is the animal power trolley and high rotary trolley. I wonder if it can be successful?"

"This..." Yuan Ling did not know the identity of the middle-aged man.

Li Shimin said: "He is Yan Lide, the Minister of Works of the Ministry of Works. He has a deep understanding of architecture and craftsmanship. His father's mountain tomb was his hands."

Yuan Ling's eyes lit up. This was a master-level figure. Yan Lide was born in an engineering family and was good at architecture, craftsmanship, painting, and built the Mount Gaozu of Tang throughout his life. He supervised the construction of the two palaces of Cuiwei and Yuhua, and built the Zhaoling Mausoleum of Li Shimin. He presided over the construction of the outer walls and the city tower of Chang'an City in Tang. With his younger brother Yan Liben was the most famous architect in the early Tang Dynasty.

When Yuan Ling studied architecture in later generations, he specially studied the topics of their brothers.

"It turned out to be Yan Shangshu... the animal power tube truck, the high-rotating tube truck was not really successful. The main reason is..." He looked around in embarrassment and said, "There is no money..."

Li Shimin, Changsun Wuji, Fang Xuanling, Wei Zheng and others were all stunned, and then laughed at each other.

Li Shimin said: "How much money is needed, you can discuss with Yan Shangshu. The funds required will be provided by the Ministry of Revenue..." As he said that, he glanced at the craftsmen around him and said: "All these meritorious people are transferred to the Ministry of Works. How many people do you need? Tell Yan Aiqing that I will give you the greatest support." As he said that, he also patted Yuan Ling's shoulder intimately and said: "Don't use this money to gamble, I am worried that I, the father and brother, will pull your skin."

As soon as he said this, Li Chengqian's face, which had been disguised, couldn't help but look a little ugly.

Although it is just an ordinary sentence, it is very different from what Li Shimin said.

Yuan Ling suddenly thought of something and hurriedly said, "Your Majesty, they have all gone to the Ministry of Works, where are the ministers? Isn't that?"

Li Shimin laughed in silence and looked at Yan Lide.

Yan Lide hurriedly said, "I can't ask for it."

"Okay!" Li Shimin said with both hands: "I will give you a position as a minister and work hard. If you succeed, you will be rewarded with another heavy reward."

Yuan Ling didn't care about how big the position Yuanwailang was. As long as he could join the Ministry of Industry and get in touch with the buildings of this era, it didn't matter anything else.

Li Shimin looked at Yuan Ling with anticipation and said to Yan Lide first: "Yan Aiqing, leave to discuss the details with the King of Shang." Then he looked at Yuan Ling and said: "I won't bother you anymore. When the car is successful, you and my brothers will talk about the past well."

Yuan Ling was a little flattered, but the reason was unknown.

With a little excitement, Li Shimin walked out of Da'an Palace with his head held high, suddenly stopped and turned around and said, "Prince, you, the sixteenth uncle, have achieved such a bad nature. This is a sudden realization that you have achieved this achievement, which shows that your potential is extraordinary. You should interact with him more or become a helper."

Li Chengqian's expression changed slightly, as if he could hear his father pointing something, and with a little fear, he said with a pale face: "Son, I know."

Changsun Wuji looked back at the plaque of Da'an Palace and muttered in his heart, "I'm so lucky."

No one knows Li Shimin's mood better than Changsun Wuji.

The attack on Goguryeo was Li Tang's future plan and Li Shimin's biggest heart disease.

There is a stumbling block in this plan now... Wei Zheng.

Wei Zheng made three remarks to suppress the process of attacking Goguryeo.

Compared with expanding territory, Wei Zheng cared more about people's livelihood. The Li Tang Dynasty had never been able to prepare for war since Li Shimin took over, and successively pacified the Turks, Gaochang, Yanqi, Kucha, and Tuyuhun, and with its invincible attitude, it exerted the power of the Tang Dynasty.

But you should know that it has only been fifteen or sixteen years since Li Shimin ascended the throne.

Goguryeo is different from the previous countries.

Goguryeo has always had a close relationship with the Han Dynasty and also belonged to a nation dominated by farming. It greedily sucked the Chinese culture. Due to geographical advantages, their construction industry was very developed. The cities were all mountain cities built on the mountain, which were easy to defend but difficult to attack.

When it comes to soldiers' combat capabilities, the Tang army is invincible, and it should be normal to fight less and fight more. However, siege and confrontation in the wild are completely different concepts.

According to the current economic foundation of the dynasty, it really supports the war against Goguryeo. But if you fall into anxiety and cannot win quickly, there will be big problems, especially in the food and grass link.

Without solving the problem of food and grass, Wei Zhengjue did not agree to launch a war against Goguryeo.

After all, Li Shimin was not Yang Guang. He did not insist on his own actions, suppressed this thought and solved the problem from the root.

At the end of the Sui Dynasty, the population of the world dropped by three-quarters, and 40 million people died in war disasters. Many people evaded corvee to survive, resulting in serious shortage of manpower.

If you want to increase grain production and increase economic taxes based on the current saturation, how to save manpower is the key task now.

Yuan Ling invented the trolley at this time, which is undoubtedly a timely help with the current political prospects of the Tang Dynasty.
