"Your Majesty, the Great Wall of the Pre-Qin period and the Illness of the Han Dynasty, one is a copper wall and the other is a mighty army. Why did the city be destroyed and the general die? It was because the Great Wall could not stop the iron hoofs of the alien race, and the general would have a day to die!"

Ning Wen didn't know what Wang De was doing, and didn't think about it, for fear that his thoughts would be disrupted at this moment. After all, he was a saint and dared not be careless. How to find an appropriate time to tell the suggestions for military logistics construction is what Ning Wen needs to consider most now. Wang De would not give Ning Wen a suggestion, nor would he remind Ning Wen of anything. Since he met several times, Ning Wen didn't know what kind of person Wang De was. Besides, there was no precedent for eunuchs to interfere in politics in the Tang Dynasty. The wise ruler in front of him was in his prime and had absolute control over the government and the **.

Li Shimin pondered and said nothing. The Wei River Alliance was a knot in Li Shimin's heart that would never be gone. Jie Li Khan's butter-filled face made Li Shimin hate it. Now that Li Jing is fighting against the Turks, he unexpectedly falls into a stalemate. If there is no breakthrough, he has to go back to the court.

The Tang Dynasty's thousands of miles of rivers and mountains were so spectacular that it was painted on this snow-white paper. However, the border was unstable and the people were displaced when there was a war, which made Li Shimin very depressed. What Ning Wen said was that Li Shimin knew, but there was no other way except to wipe out. Unfortunately, the Turks were nomadic people. It was not easy to annihilate them in one fell swoop. At worst, they could recommend a Khan and then there was a continuous war.

Li Shimin subconsciously looked up and saw Ning Wen drinking tea. He suddenly felt that this boy could have a solution? Li Shimin was very suspicious, how old Ning Wen was, could it be that the young man in his early twenties was Zhang Liang and Zhang Zifang resurrected?

"What Guangcheng said is very true, and I often have a headache about this. Could it be that Guangcheng has already been concerned about it?"

Ning Wen stood up, saluted Li Shimin in a regular manner, and said in a deep voice:

"I dare not, Your Majesty, I have a sudden idea. If you are right or wrong, I hope Your Majesty will forgive me for being arrogant."

"Haha, but it's okay, I will naturally not blame you."

Li Shimin felt a little nervous. Is there any way this man really possible? It’s okay to listen to it without any trouble, but I don’t know what kind of ability this kid has.

"Your Majesty, the border has always been a wild place. Without it, it is all burdened by war. People cannot live in peace and cannot be happy. Whether it is garrisoning or garrisoning, they all need to be fed by the mainland. The official road is rugged and mountainous. It takes half a year to travel thousands of miles. I suggest that one: reorganize chariots and horses and widen the official roads. There is such a carriage style on the drawings of Weichen. Your Majesty, please see, this carriage has been added with springs and the bearings are also made of steel. The download weight can be doubled without increasing the horses, and the speed is also greatly increased."

Ning Wen pointed to the carriage style on the drawings and explained to Li Shimin one by one. Now the weapon supervisor has successfully tested the relatively durable bearings, mainly because of the improvement of steelmaking technology. The converter drawings have been drawn, so I just waited for Master Zhou to find a way to cast them. Of course, Ning Wen was mentally prepared for the various difficulties in the middle, so he should not be busy for a while. The weapon supervisor has sufficient resources, which can make Master Zhou trouble for a while.

The power of four horses, four steel and wood combination wheels, two steel axles, eight six-inch diameter bearings, and fir and angle iron cabins formed the carriage with the largest load capacity in the Tang Dynasty. If the Guinness World Record is now, this carriage is definitely maintained with many records. During the last experiment, it easily pulled two thousand kilograms of iron blocks. During the Ning family's material transportation between Chang'an and Lingnan, I experimented with a round trip. Including the distance is almost 5,000 kilometers, I only broke two wheels and one bearing, which was considered strong.

"Oh, there is such a heavy carriage in the world. I will try it myself another day. Ning Wen, you continue."

Li Shimin wanted to drive a weapon surveillance now, but Ning Wen had not finished speaking. This was just one of them. The carriage and horse were renovated, and Ning Wen had not said anything yet. Li Shimin was eager to know the following.

"The official road is like the bloodline of a person. If it is open, it will not hurt. If it is open, it will not hurt. I walked all the way from Lingnan and saw that some roads have been disrepaired for a long time. This is still in the mainland, and the border areas must be even more unbearable. No matter how good the car is, the road is overwhelmed, and at that time I can only sigh at the road!"

"Ning Wen is very worried. If the road of a carriage of two thousand pounds is not disappointed, I feel that it is inappropriate. Can Ning Wen have a wonderful way to solve it?"

Li Shimin was a little convinced of Ning Wen's words, and Ning Wen was happy to strike while the iron was hot, so he said again:

"Planning roads and refining roadbeds, without a solid foundation, there is no flat road. The three-combination soil is also recorded on the drawings presented by Weichen. It is the best paving material before cement firing."

Sanhe soil has been used on Ningjiazhuangzi in Lingnan, and Ningwen has improved it. Sanhe soil is mixed with carbon slag powder, which can absorb water and be durable.

Li Shimin nodded, and without waiting for Ning Wen to continue speaking, he closed the text and pictures presented by Ning Wen. Ning Wen was also very tactful and sat honestly on the chair waiting for Li Shimin to speak.

"Ning Wen is loyal and I am deeply pleased. Chengqian, come in!"

Li Shimin called in a low voice, Ning Wen thought he had heard the fork, why was the prince there too? For a moment, Ning Wen felt like a big rock was blocked, and he was so breathless that he was breathless. It was not that enemies would not gather. He originally wanted to present these things to Li Shimin in order to see what happened in the sun. Li Shimin could think of his contribution and make a fuss about his contribution, but as soon as the prince got involved, Ning Wen's thoughts were gone. How could he not feel uncomfortable?

Wang De understood the meaning of his whisper just now. There was someone behind the screen. Ning Wen only remembered that the little loli was hiding behind the screen. This time, he didn't notice that Ning Wen just wanted to give himself a few strokes. What kind of eyes are you looking at from below, and you can't hide your feet. Why don't you look at it?

"I have met Your Highness the Crown Prince!" Ning Wen maintained his demeanor very well. Since the person has appeared, it will be useless to say anything now. Come and see him.

"Haha, Guangcheng, it's been half a year since I spoke that day?"

Li Chengqian was still so full of spring breeze. He narrowed the distance with just one sentence, which made Ning Wen not feel that he was rude, but he felt a chill on his vest.

"I hope that Your Highness the Crown Prince will forgive you. I am busy with weapons supervision and forget about the pigeon. Tomorrow, I will definitely send it to the Crown Prince himself!"

"Haha, it's not a big deal. Ning Wen will talk about it when he has time."

Without giving Ning Wen a chance to regret, Li Chengqian sat back to Li Shimin's lower head, kept a smile, and waited for his father to speak.

"Pigeons, you're so disappointed!"

Li Shimin frowned, flirted with Ning Wen's manuscript, took out one from it, handed it to Li Chengqian, and then said:

"Look, pigeons are of great use. Oh, when will you relieve me!"

Li Chengqian quickly took it with both hands, lowered his eyebrows and said with a smooth look:

"The boy realized he was wrong!"

Li Shimin didn't say anything, waved his hand, and Li Chengqian sat aside with fear and fear, looking at his nose and his heart, which was more honest than Ning Wen.

"Chengqian, these are all the hard work of Master Ning. I plan to let you take charge of the car and road construction. If you have any unclear points, just ask Master Ning and don't let me down!"

Ning Wen was completely petrified. At this moment, Li Chengqian and Ning Wen were afraid of avoiding it. This was fine. Li Shimin directly left Ning Wen and planned to give the subsequent military logistics construction to Li Shimin. He was not interested at this moment. In addition, Li Shimin had no intention of continuing to ask, so Ning Wen quickly retreated, intending to go back and stay at home and breathe happily, which was to let his broken heart rest, but Li Chengqian was held back, saying that he would go to the East Palace to talk about building cars and repairing roads. OK, this was a matter arranged by the emperor and could not be neglected. Ning Wen cheered up and followed Li Chengqian to the East Palace.

The East Palace is the residence of the prince. If anyone enters the East Palace, it means announcing to the general public that the fuck is the crown prince. After the emperor abdicates a hundred years later, or abdicates the throne like Emperor Gaozu, the owner of the East Palace will be able to directly take office and become the true dragon emperor and the ruler of the people of the Tang Dynasty.

Ning Wen felt that he was in bad luck and there was no one around him who could discuss it. Guo Enxiong was still on the road and he arrived just before the New Year. Ning Wen couldn't find anyone to tell him about his thoughts and dared not say anything. Who knew what Ning Wen was pretending to be in trouble? He would definitely not be able to sleep at night.

As soon as he arrived at the East Palace, the car stopped. A wrinkled eunuch lifted the curtain of Ning Wen. Seeing the eunuch, Ning Wen suddenly thought of Wang De, why did Wang De want to whine to him just now? Could it be that Wang De and Li Chengqian have any holidays, or what Wang De has to think? Ning Wen followed Li Chengqian into the main hall of the East Palace with questions.
