"Haha, I don't know if the prince is here, I will be welcomed by mistake. I will forgive my crimes." Yang Heng intercepted the prince of the Li family on the way, and said sourly.

"Haha, it's easy to say, it's my king's that I didn't go to inform Guixian." Li Daozong also bowed to Yang Hengyi immediately, "I knew you would go to report the news. Come, nephew Xu, tell Uncle Wei what you think."

Li Daozong complained about his son, and then pulled Yang Heng and walked forward together.

"Prince, look at the avenue I designed." Yang Heng pointed to the initially developed road under his feet. "Are you going to build a road on the grassland?" "Well, yes, my road is ready to lead to the imagined border trade city. Prince, look here, after a period of transportation, the road has taken shape. In addition, I arranged for people to dig ditches on both sides. Isn't this avenue? Also, I plan to lay this avenue with cement, so that this is a fast avenue."

At first, Yang Heng did not plan to build this road first, but when the carriage transporting materials passed by here, it slowly pressed out a road. However, the carriages were all heavy cars. Once the road was crushed, it affected the walking. Yang Heng temporarily drew some people to dig ditches on both sides of the road. The digging soil was just paved on the road, and the road gradually took shape. Of course, the contribution of his wild horse herd was indispensable here. Every time he walked the horse, the wild horse herd would walk on the road, so that the newly padded soil was compacted, and then after passing the carriage, the shape of the road became more obvious. Yang Heng even planned to plant several rows of trees outside the ditches on both sides of the road. In this way, the road would have a shape of later generations.

"But nephew Xu, what should I do if I have a city defense or cross the river?" Li Daozong raised a very realistic question. You should know that inside and outside the Great Wall passes through the county town. If a prosperous road passes through the county town, it is easy for some spies to enter the city and open the city gate without paying attention. Then this city is dangerous.

"This, Prince, I plan to close the gate leading to the outside of the city. If there is no military operation, the door will generally not be opened. There is a separate pass on the Great Wall and even an iron bridge is built on the river there. Isn't this problem solved? There is no trading area in the county town. This will avoid trouble."

"Well, this idea is good. Especially when a single thousand-jin gate is set up on the city wall, so that if an enemy army enters the Great Wall, the city gate can be closed in time."

"Qianjin Gate?" "Yes, this is based on your idea. If someone comes in, it will be too late to close the city gate. It is okay to put the Qianjin Gate. We also have the city road next to us. Isn't it appropriate?" Li Daozong said easily, but how to do this Qianjin Gate?

"Are you considering how to do a thousand jin gate? Don't you have a lot of steel? You can do it with steel?" Oh, I actually forgot that this is out. Sometimes, it's not as flexible as the ancients. Yang Heng patted his head hatefully. Although he had never seen a thousand jin gate, Yang Heng understood its principle. This is a thing mentioned in the storytelling in his previous life, even in the game. It is a piece of steel plate that slides on both sides and pins it with a mechanism. When it is urgent, knock off the mechanism with a hammer, and the thousand jin gate falls. Then, it will be a lot of trouble to lift the thousand jin gate up, but a war will also be caused by the fact that it will be because of the

The addition of Qianjin Gate changed, and Yang Heng could even separate the city wall from the city gate. People could not go up and down to the city gate, nor could they go up from below to the city wall. This was just a small change. The people guarding the city gate were divided into two parts. Some of them opened and closed the city gate under the city, some of them looked at Qianjin Gate on the city wall, and some of them looked at Qianjin Gate on the city wall, and some of them looked at the city wall. This, Yang Heng became happier the more he thought about it, "Well, just do it like this, thank you, the prince, but you need to report to Your Majesty, right?" "That's natural. You thought you could open the city gate on the Great Wall and build a bridge on the river. Let's go and take a look at your so-called castle."

As he spoke, Li Daozong accelerated the horse's speed. What he was most concerned about now was the castle matter. I don't know if this thing is very suitable, otherwise Yang Heng would be suspended.

The first castle now has a primary scale and is even about to be capped. At this time, Li Daozong came.

"Brother, this is what you are talking about. It's not so good. Such a small building?" Li Yuncong asked in confusion as he looked at the building in the distance.

"I said, man, don't underestimate this castle. If people from outside have people who come from outside, they don't have giant trees and catapults, it will be difficult to capture this place. Moreover, this place does not need to be built too large, but it can temporarily put down more than a thousand livestock, and more than a hundred people will become."

"Ming Gong, Ming Gong." When Yang Heng approached Li Daozong, the craftsmen and grassland tribes greeted Yang Heng, "Come on, let me introduce to you, this is Prince Li of our Tang Dynasty, Prince Li, this is the little prince." "Hello, Prince, hello." He asked in a mess again, but fortunately, none of them kneel down, which is what Yang Heng is more satisfied with. At this stage of the Tang Dynasty, people's kneecaps are still relatively hard. They don't mean they have to kneel down casually, that is, under extremely grateful conditions, or in some other special circumstances, kneeling will happen.

"Okay, you guys are busy with yours, I'll take a look." As he said that, several people entered the construction site. "Prince, put this on." Yang Heng took out a few willow-woven hard hats from the side and gave them to Li Daozong and Li Yuncong. "You guys, don't come in, it's too small."

"Is this?" Li Daozong asked with a hard hat, "This is a hard hat, to prevent objects from falling from falling from high places." Yang Heng just said simply, and he first put it on his head, "Well, this is a good thing, I wonder if it can be used on the battlefield?" "This is OK, it is not durable. If you smash it a few more times, it will break soon." "It can withstand several times." As he said that, he not only put it on, but even tapped it with his fist a few times. "This thing is better than an iron helmet, at least it is light and there will be no sound. If you can withstand three times, a war will basically end."

"Yes, if you use this to woven vine armor, it will be very light, but you are a little afraid of fire." Yang Heng suddenly remembered, isn't there a vine armor army in the Three Kingdoms? As long as these branches are processed, they can be woven into vine armor, or even horse armor.

"I won't talk about this anymore. I'll write it down first. You can introduce the structure of this castle to me first." Li Daozong still remembered that he was here to patrol the castle, so he naturally won't say anything else.

"Your Majesty, you see, this castle is fifteen meters in radius. This is the front yard. The front yard is divided into two floors above and below. These two floors are large livestock on the ground and small livestock on the upper floor. Although it is a bit crowded, all the livestock in this place can be put in. Moreover, the walls of the castle are made of bricks, cement, and stones. They are made of giant trees to hit, and it is difficult to hit in a short period of time. The height of the wall is more than three meters high, which can completely avoid climbing by outsiders. Naturally, you can't hold on for a long time, but what we need is three or two days, right? There is also a well here..." Yang Heng led Li Daozong to introduce the structure of the castle to him one by one.

"The most important point is that there are enough people here to defend the grassland direction, but if our army comes to attack, they will not be able to hold on. I have extra weapon, and this Majesty knows."
