With the strength of the Youshi family's control over the entire Youyushan tribe now, there is no resistance to the implementation of the city-building task, on the contrary, it has the strong support of all the sub-tribes, after all, once this city is built, no one will be able to shake the status of the Yushan tribe in the Yushan Mountain Range.

Regarding the address of the new city, Tian Tiannan overrode the public opinion and set it in front of the two sacred mountains of the wolf tribe.

First, it has a basin of several square kilometers in size, and the terrain is easy to defend and difficult to attack; Second, there are two sacred mountains behind him that have been basically hollowed out, and they can be used by the new city with a little transformation.

Between it and the main peak where the Yusan tribe is located, there is a narrow and gentle passage that is more than 100 meters wide, and the two mountains next to the passage have become the breeding grounds of the Yuyu mountain tribe.

Tian Tiannan's plan is to build a new city in front of the sacred mountain, and then use the sacred mountain as a city wall, and add the entire sacred mountain to the new city system, the new city will cover an area of 5 square kilometers, and the current Yushan tribe will be transformed into a military camp, existing in the form of an acropolis, and this gentle land in the middle of the two cities and the two breeding mountains next to it will also be included in the new city system.

All the trees on the gentle ground were cut down, and the gentle area and the two breeding hills were enclosed with arrow towers and walls as a connection between the military camp acropolis and the main urban area, so that the actual area of the entire surplus city would exceed double digits, and the gentle land in the middle could be used as a field as long as it was slightly renovated and then reclaimed with diamond rakes and livestock fertilizer from the breeding mountains on both sides.

There were also many gentle areas in the acropolis, and the water source was also very abundant, so that the tribal soldiers could farm in the barracks when they had nothing to do, so that the food produced by the two pieces of land could fully feed the 50,000 people in the city, plus the livestock and fruit trees on the mountains, there was no problem in self-sufficiency.

After listening to Tian Tiannan's idea, the Youyushan tribe finally agreed, so next, from the early ten years old to the nearly fifty-year-old old, tens of thousands of men in the entire tribe collectively mobilized and began to mine stones on the main peak of Youyu Mountain.

First, the main peak of Youyu Mountain will be dug up to a small half is enough for the construction of the new city, and at the same time, the dug part can also be used to build a military camp acropolis, the original Yushan main tribe is not large, and the three thousand people living in it are already a little crowded, and if the area is not expanded, the future five thousand standing combat forces will not be able to be stationed here at all.

(Note: The ratio of military strength is set at 10:1 should not be too much, although the population base is not large, but all the people are soldiers, and even the old grandfather can go to the battlefield if he is trained into a soldier, although the physical strength will be relatively low.) ）

In order to ensure that nothing went wrong during the construction of the city, Tian Tiannan also deliberately deployed a team of barbecue and Tiannan cavalry in the mountains, and sometimes even patrolled around in December.

And as the chief commander of the project, he must always sit on the new site of the new city.

It is worth noting that during this period, Tian Tiannan discovered another benefit of the logistics attendants, that is, they who can use the system workbench are fully capable of the responsibilities of regional management, plus Miao Miao, Xiaowu and Shrimp Shrimp The three major treatment attendants are in charge of each area for him, not only the construction task has been accelerated, but his own burden has also been sharply reduced.

In order to stimulate the enthusiasm of everyone, Tian Tiannan directly issued a clear reward system, not only those soldiers, even the elderly and children, as long as they work hard and get the affirmation of the attendants, they will directly reward the sacrifice point with real money, and the wealthy Tian Tiannan also erased the decimal point, and the lowest directly starts from 1 point.

"Father, isn't it a waste for Tiannan to do this?"

"You guys, do you know how many new warriors have been born in the tribe in the past month?" Faced with the worries of the children, Ji Yuedai's husband asked them rhetorically.

"How much?"

"Yesterday, it broke through 500!" You Rong said lightly.

"What !!"

"All the sacrificial points sent by Tiannan are in our name, but most of them are paid for by him, and even the cost of building the city is lent to us by him."

"Have you ever thought that these newborn warriors still belong to our Yushan tribe in the end, and now we continue to strengthen ourselves, but if we rush to cultivate warriors without merit, there will definitely be a series of problems in the future, but if this is earned through their own efforts, there will be no such hidden danger."

"Not only that, the city built by them brick by brick, the sense of belonging to it is bound to be very deep, invisibly, the problem of tribal integration has been solved, everyone eats and lives together, promotes warriors together, and everyone has a helping hand if someone has difficulties... When this city is built, the Yushan tribe will be completely integrated! ”

"You, from tomorrow onwards, you will all go to the construction site to quarry stones,! How is it that this biological child is not as good as half of the child? After saying this, Rong became more and more excited, and finally even roared, which made everyone present stunned.

"Damn... There are so many ways to build a city, and sure enough, I have to follow that kid from Tiannan to be more gangsters! Walking out of the patriarch's hall, Youying dared to wipe the saliva that his father sprayed on his face, and his face was entangled.

Looking at the others, the expressions on their faces were not much better, but after Daddy's words, they all began to correct their attitudes, and the next day they took pickaxes and shovels and went to the construction site.

"Ji Yue! My thanks you gave me a wonderful daughter..." Standing on the mountain and looking at Youyucheng, which gradually took shape, Yourong sighed with emotion.

"Then my patriarch, would you be interested in comparing me with who has built stronger walls?" Zhun turned his head to look at her husband, Ji Yue smiled.

"Hahaha... It's exactly what I want, go, today I'm going to revive my husband! Secretly sighing in his heart that his wife was a roundworm in his stomach, Yourong laughed and picked up the guy that had been prepared a long time ago, and under the gaze of his wife, he walked side by side with him, and joined the construction army.

Even with Tian Tiannan's powerful system, it took tens of thousands of people nearly two months to build all the city walls, and the city walls of the main city were as high as 25 meters and 6 meters thick.

When all the city walls were completed, standing outside the main city gatehouse, the Youshi family looked up at the city gatehouse, which was already majestic in this world, and was silent for a long time, only the most excited little one ignored the presence of his family, and directly sent his own fragrant tongue to Tian Tiannan to taste, and after that, he gave him a "night" and "you know" look, looking at the swaying mountain, Brother Tiannan couldn't help but feel a wave in his heart, and kept swallowing saliva.

The city wall is completed, the next is the construction of the city, Tian Tiannan designed two main roads for the city, at its intersection is the city lord's mansion, the city lord's mansion is 200 meters long and wide, covering an area of about 60 acres of land, as only one family can enter the "small inner city", here will be the most tightly defended place in the whole city in the future, and it is also the most luxurious place for the building.

The two main roads divide the main urban area of Yucheng into four areas, each area is divided into nine small areas, the middle area is used as a market and commercial area, and in the future, when the tribe is richer, Tian Tiannan will consider allowing the tribe people to develop business and catering industry, etc., and the other eight areas are residential areas, and each district can ideally accommodate about 1,000 households.

In this way, Tian Tiannan only needs to build the 3rd and 4th districts located on the side of the main city gate in the early stage, and the two districts are enough to accommodate 7 or 80,000 people.

In addition to this, the two great sacred mountain caves Tian Tiannan are also preparing to transform one out and use it as a warehouse.

In order to allow the city guards to reach any section of the city wall as quickly as possible in an emergency, a runway with a width of more than 10 meters is left under the city wall, and corresponding to the city tower on the city wall, and a single three-story building will be built under the city wall.

In peacetime, it can provide a place for patrol soldiers to rest, in wartime it can be used as a medical station, and in wartime, a floor will be set aside to store various supplies, so that they will not need to go to the warehouse to collect them when they need to replenish them.

In addition, there are various necessary facilities such as drainage systems, Brother Tiannan has taken great pains for this city, and smashed into millions of sacrificial points before and after, if it weren't for the whim of the previous establishment of a poor tribe as a production area, where could he get so many sacrificial points at this time, every time he thought of this, he had to rejoice in his original whim.
