One leg is not worried that Chi Nan is walking alone on the road, and he will soon catch up. It's really hard to be embarrassed about a leg, and I can keep up with myself with just a prosthetic leg made of wood. Perhaps, I should give him a new leg.

It's just that there is no way now, I can make a piece of wood that looks the same, but I can't control it. This is not a nerve prosthesis, and even if it is installed, maybe one leg will not get used to it.

Chi Nan simply slowed down, thinking as he walked: "The soldiers' equipment, as well as some daily necessities on our side, many need to be solved. So we need a lot of iron, do you know what iron ore is in this place. "In the end, Chi Nan can only rely on this.

"Iron ore? This subordinate has really inquired, and there are no ore veins on this side of Hongshaling. ”

"What? There are no veins? How is it possible, the red stone mountains are all red, that's the sign of iron ore. I remember that wherever there was iron ore, there would be this kind of red stone. ”

One leg said helplessly: "My lord, it is said that someone has come to Hongshi Mountain and Hongsha Ridge to explore before, and there is indeed a large amount of iron ore here, but it is too scattered and has no mining value at all. ”

After telling on one leg, Chi Nan understood. The stones and soil here do contain a lot of iron, but it is as if rust has been stirred into the sand, and it is too scattered and not very high.

In addition, the smelting level of this world is not good, and smelting this kind of stone is more than worth the loss, so no one wants to pay attention to the stones here at all. But they couldn't do it themselves, and in the end, so much iron on Redstone Mountain could only be thrown here. In fact, even if the smelting level is high, I'm afraid no one wants to.

The iron content of this entire mountain may be comparable to several large iron ore veins, but this mountain is too big, and whoever is in the mood to refine this mountain little by little is better to find new iron ore.

"I see, it's really troublesome. Chi Nan looked helpless and thought about it again.

There is no way to solve the problem of iron ore for the time being, and Chi Nan can only focus all his energy on experimenting with his pea cannon. Every day except for experiments is experiments, and it is good to leave things to other people anyway.

In terms of civil affairs, with Hemila here, everything is in order. There is alfalfa at home, although it is not very eye-catching, and it is very old. But alfalfa is very good at housework, and the house is well organized.

Now, the place where Kenan lives is a treehouse built from a large tree next to the castle, which is far worse than the castle with the same dilapidated house, but at least it is comfortable to live in.

The army side just handed over a leg, and the bald dad is basically giving himself a message and running errands, and where there is a need, he will go over there to help. seems to have no real power, but he is a figure that no one dares to underestimate.

In the blink of an eye, a week passed, and nothing happened. On this day, the bald father suddenly found himself and said that the three-story city wall built in front of him had been completed. Chi Nan immediately put down what he was doing, hurried to go, and soon ran to the edge of the city wall.

After this period of busyness, the nearby loess has been planted with jujube trees, and there are many oil trees. The people have become accustomed to flour as a staple food and have discarded all their previous foods.

There is nothing troublesome for the time being, and the speed of the construction of the city wall is naturally very fast. The city wall in front of me, although it was only piled up, was at least six meters high, and there were ladders erected next to it.

"Very good, very good, it's really hard for you, leave it to me next. ”

"It's not hard, these are what we should do, and it's the lord who really works hard. ”

Chi Nanyi waved his hand: "Okay, don't say these nice words, everyone has to pay." We are all for the future of our territory, for a better life for our future. ”

Chinan's words made the surrounding workers very happy. Chi Nan didn't pay attention to them, and stepped forward, still the same as before, first using the improved tripping horse grass to strengthen the three-story city wall.

After the reinforcement, Chi Nan took out the seeds and handed them to the workers. "Go, plant in the middle of the wall, and in front of it, two meters apart, one seed every two meters. "These are nanmu seeds that Chi Nan took out, but they are not ordinary nanmu. During this time, the people sent themselves some special plants.

This kind of Nanmu wood has a hard texture, a little fragrant taste, and tenacious vitality, but the growth rate is slow.

Although this is only a big tree that is not as good as the quality, because of the talent in hardness, Chi Nan can strengthen the hardness of Nanmu to the hardness of a black iron level tree, and the consumption is not as great as that of directly using black iron plants. The tree itself has the ability to grow and repair itself, and its own walls are unique in this world.

Once the workers planted the seeds, Chi Nan began to use his magic. During this time, he continued to experiment and grow various plants, and the magic of Pondan was much stronger than when he first came here.

The first row of nanmu trees grew rapidly, gradually forming a large patch, which was completely connected and fused together, as if it were a single plant. This pure wooden wall was formed.

On the surface, there is also a little metallic luster, and it is very hard at a glance. The gates of the city were vacated, and the trees on both sides spread from above to each other towards the middle, and finally came into contact. The stone wall was completely encased in wood. The very top of the city wall was also rapidly deformed under the control of Chinan.

The flat ground and the zigzag-shaped female wall in front can effectively protect the soldiers behind. Their own soldiers defend the city, as long as there are pea cannons, and they don't need any other weapons at all.

After thinking about it, at the edge of the outermost layer of the city wall, Chi Nan once again gave birth to a large number of sharp wooden spikes.

"Hmph, with these wooden spikes, I don't think anyone else would dare to climb up from outside the city walls. "These spikes are very sharp and very elongated. Even with a ladder, there was still no way to separate the spikes.

With such a wall, everyone suddenly felt much safer. "Afternoon continues, I don't have any magic anymore. Chi Nan spread his hands helplessly, it was also very tiring to give birth to so many nanmu to form a city wall. There are four walls in total, twice a day, and it only takes two days for the walls to be completely completed.
