After chatting with Wu Chaogui, Chen Yuan also crossed the river from the wooden bridge, which was the second time he came to this Jiangxinzhou land.

On the high ground on the west side of the continent, Chen Yuan saw that Chen Shuyuan and the others had already painted most of the steel castle with white ash here. Where are the city walls, where are the houses, where are the streets, where are the warehouses and canteens, and where are the ditches to be dug are clearly marked.

Chen Yuan's pride suddenly dawned, and through the white ash on the ground, he suddenly seemed to have seen a magnificent and safe fortress standing here. People can live in peace here, there are soldiers standing guard on the city walls, children playing in the streets, blacksmiths clanging and iron, many people in and out of the bathhouses with baths, warehouses full of supplies, and restaurants with the smell of food. For a person who has lived in the last days for 18 years, such a picture of life is really too beautiful.

More than 300 survivors who came to Jiangxinzhou before Chen Yuan had already stacked wood in an open space under Chen Shuyuan's guidance.

Then, they were assigned in groups of eight people and began to dig in the marked places with sapper shovels. The scene was very lively.

However, it was obvious that the excavation work would not end so soon, so after taking a little look at the work of the people, Chen Yuan went to inspect the sentry of the artillery team. It's even more important here. With so many people working on the construction site, it is very dangerous if the protective measures are not taken properly.

Jiangxinzhou is protected by the Nenjiang River, and ordinary zombies can't come. But it is not absolute, among the zombies and zombie creatures, there are some types that can easily cross the Nenjiang Heavenly Danger. For example, the flying corpses in the enhanced species, and the wind mutant zombies in the mutant species. In addition, the large siege equipment of the Zhi corpse and the long-range attack of the cannon corpse can also cause damage to the people on the ground in Jiangxinzhou across the river of Nenjiang. There are also many zombie creatures that can burrow or swim.

Therefore, even if everyone is now in Jiangxinzhou, sentry is also necessary.

Chen Yuan asked Chen Shuyuan: "Dad, do you know where Xiao Tengcan is?" ”

"I think it's on the east side of the construction site." "This is the sewer in the southern part of the settlement, and you have to dig down the dotted line, until you dig until the middle of the settlement is connected to the main underground water channel running east-west," he said. In the future, the drainage, water, gas, heating pipes, and electrical wires and pipes in our settlement will all go from here. Therefore, we must excavate in strict accordance with the standards, so as to avoid us from digging and filling again in the future. The width should be two meters, the depth should be four meters, and a walkway half a meter wide and half a meter high should be set aside on each side of the underground. ”

Chen Shuyuan was very critical of the layout of urban pipelines in the past when municipal drainage, tap water, power transmission, and gas transmission each had a set of pipe networks. In order to reduce the amount of work, the pipes of each part will only be dug just the right size, and the pipelines will be laid out before being buried. However, although the amount of construction is small, the subsequent development is not considered. Once the carrying capacity of the pipeline is insufficient, it is necessary to dig the old pipe network again along the original pipeline and re-route the pipeline.

This is true for drainage, this is true for electricity transmission, and the same is true for water pipes. As a result, in the past, in cities, pipes were often dug either here or there, and the same section of road had to be dug every once in a while. Not only does it make the city dusty, but it also adds a huge burden to the city's traffic.

Now the work of settlement planning is entrusted to Chen Shusheng and Chen Shuyuan themselves, of course, taking advantage of the current availability of manpower, to directly learn from the Western urban sewer design, and to excavate a large-scale comprehensive sewer network along several major arterial roads. In this way, all the pipelines that need to go from the ground can go from here. And because the underground space is large enough, workers will need to rearrange the pipeline in the future, and they can go underground with the pipeline to replace it, without having to dig the pipe from the ground.

Chen Yuan saw that Chen Shuyuan was very serious about directing the survivors to excavate, so he smiled and left. He knew that his father was so engaged in his work that he didn't have time to pay attention to himself. So he walked along the construction site by himself towards the east side of the Iron Castle site.

Here, Chen Yuan really found Xiao Tengcan, who was holding a telescope and carefully observing the eastern sky. Chen Yuan greeted: "Brother Xiao! ”

When Xiao Tengcan heard Chen Yuan's voice, he put down his binoculars, turned to see Chen Yuan, and asked, "Castle Chief, why are you here?" ”

Chen Yuan smiled and said, "I'll take a look." He asked in passing: "Are the defensive positions on all sides arranged?" ”

Xiao Tengcan confidently introduced to Chen Yuan: "After nearly 30 fighters of our artillery squad arrived on the island in the morning, they were divided into three groups in accordance with the regulations, which were arranged in the east, south and north directions of the steel fort construction site. There are at least 9 fighters in each direction, two bazookas. As long as the flying corpse or the wind mutant zombie dares to come, it is guaranteed to be able to knock them all down! "Because there is Hatu Village in the west, there are enough defenses there to ensure that zombies can't fly over the west, so they don't set up a defense line here. And according to the plan, after the wooden bridge is built, a squad of fire support team members will also be arranged here to defend here.

Chen Yuan nodded, took Xiao Tengcan's telescope and looked at the east bank. Here, there is a larger village called "Lijiatun", which is located on the east bank of the Nenjiang River. It is also the closest village to Jiangxinzhou, and the number of zombies is expected to reach about 600-800. This is a piece of Chen Yuan's heart, because there are likely to be flying zombies in such a large-scale village. As for the engineering equipment of the cannon corpse and the intelligent corpse, I am not very worried, because the width of the river here is at least 1 kilometer wide, and ordinary zombies can't pass through. In addition, the eastern part of Jiangxinzhou is also 2 kilometers away from the shore to the height where the Iron Fort is located. The engineering equipment of the cannon corpse and the intelligent corpse can't hit that far now.

Chen Yuan took the telescope and asked while looking at it, "Is there a situation in the village opposite?" Have you found any flying corpses? ”

Xiao Tengcan nodded and replied, "Two were found this morning, but maybe they haven't found us yet because they're too far away." So I never came. Otherwise, we would have beaten it down a long time ago. ”

At this moment, Chen Yuan also saw a flying corpse slowly flying up from the village, but it did only hover at a low altitude above the village, and had no intention of flying to this side of the continent. In fact, at this stage, flying corpses are not yet able to fly long distances, so they generally rarely fly far away. Unless they find an obvious target.

So Chen Yuan said: "You can't just wait for them to come to the door by themselves, you have to find a way to take the initiative to knock them down, and I will transfer Wei Chen over first." Let him sneak into the river to kill them. ”
