Chen Yu came to Gu's house, Gu Qingzhou was still very happy, after all, he and his wife were the red line of this sister-in-law's move, and Chen Yu was different from others, Gu Qingzhou and Chen Yu were from the same place, and the two were also in love, so naturally the relationship was better.

"I'm here today to find you something, and maybe you will be interested in this matter too." Chen Yu said.

"Oh, what's the matter? Could it be that you've found a way back to Earth? Gu Qingzhou asked.

"That's not true, but there's still a chance, I've now mastered the way to travel through time and space, and I've found another world, a primitive world. It's just that there are so many worlds, and I'm not sure I'll find the earth before I die. But this time I came to you to build that world, and I've already sent an advance team, but I don't know much about it, so I'm here to ask you. Chen Yu said.

"What? Another world! Gu Qingzhou said in surprise, but quickly calmed down: "Since we can all cross over, then there are many worlds, which must be true, but what kind of world is that world?" Is it worth developing? Can you find another world? If you can, why bother developing a world without people. Gu Qingzhou said.

"I'm going to use that world as my base, after all, no one is completely developed by their own people, so it's completely in their own hands, and the resources of that world are also very rich, so why not do it with low investment and high returns. And even if you find the world later, that world will be useful. Chen Yu said.

"Also, you have a contract to ensure the loyalty of your subordinates, and if you do develop it, there are still many benefits, but is it so simple for so many people to travel to another world? How can I not think it is reliable? Gu Qingzhou said.

"I've opened up the passage between the two worlds, just walk over it, it's not a hassle at all, if you have time, you can also go and see and feel it." Chen Yu said.

"Forget it, but if you find any interesting world in the future. Or the earth, I can go and see it, and there is no need to see a primitive world without people. But if you need any help, I'll figure it out for you. I'm not a big fan, but I still know a lot of knowledge. Gu Qingzhou said.

"What I need most now is to build a city, so there are a lot of things to pay attention to, and although it can be completely built like an ancient city now, I decided to add some modern technology to it. Lest the city not be strong at all, after all, there are many fierce beasts in the primitive world. Chen Yu said.

"Then what do you need, as long as I can help you, I will definitely not refuse." Gu Qingzhou said.

"You write me a copy of some of the knowledge you remember about architecture, materials, etc., I will let my subordinates study it slowly, first wait like this, I will find a high-tech world later, and then introduce more technology, anyway, the people who go now are people from this world, and the requirements will not be very high." Chen Yu said.

"Actually, you don't need to be in such a hurry. After all, your other world is definitely not small, and you definitely won't build only one city, so why not build an ancient city first, and when you have the conditions in the future, you can build some more others, wouldn't it be good? Gu Qingzhou said.

"What you said also makes sense, then I'll arrange it first, thank you so much today." Chen Yu said.

"Don't be so polite to me, speaking of which, I'm also your brother-in-law now, I'll send it to you after I've written it. You and your sister talk first. Gu Qingzhou said.

"Okay." Chen Yu said.

After talking to Gu Qingzhou, Chen Yu stayed at Gu's house until the evening before going home, of course, this trip was not bad, Gu Qingzhou was a technical nerd. It's really much more powerful than Chen Yu, and he can remember so many useful things, how can he be like Chen Yu.

A few days after Chen Yu returned home, he sent the compiled materials to the primitive world, and also added 500 people, so that these people began to choose a site to build the city. To build an ancient city, there is no need for any technical content at all, Chen Yu can build it regardless of the talents under him, but it is divided into a longer time or a shorter time.

Because of the increase in manpower, the work ordered by Chen Yu and the development and transformation of new processes were carried out relatively smoothly.

Building a city is not an easy task, first of all, you have to choose a place, find a suitable terrain and location, but also consider all kinds of factors, in addition, there are basically no roads in the primitive world, and there is no means of transportation, which limits everyone's work progress even more.

But fortunately, the place where Chen Yu chose to come also had some considerations, so there was a suitable place not far away, and it was a drop in the bucket for these hundreds of people to build the city, so it was just the preparation work before starting to build, and when more people arrived, they would build the city together.

The first thing to be built must be the city wall, because for the safety of the people, the city wall is the most important, can avoid the invasion of wild beasts, so after these hundreds of people are ready, they start to build the city wall, even if there is a shortage of manpower, they are a little bit of the city and come out a day early.

The materials of the city wall were originally intended to use stone and earth, but after the cement was available, it was ready to be built with stone and cement, and for safety, the city wall was built extremely thick, not to mention wild beasts, even the tide of beasts could not shake the city wall.

And for convenience, the city wall is also designed with some organs, as well as some places to garrison, the entire city wall is very tall, most of the time, hundreds of people to build the city wall, it is just a beginning, but the scope of the city wall is determined, and the foundation is also leveled, just wait for Chen Yu to bring more people to build the city wall completely.

Chen Yu saw that this place was not as dangerous as he imagined, so he felt that it was okay to bring in the newly trained 100,000 people, and it could also be used as cultivation while building a city.

However, 100,000 people is not a small number, so it is also in batches, Chen Yu from all over the country went to the primitive world, 100,000 people seems to be a lot, in fact, it is nothing at all, it has not set off a trace of waves at all, maybe Chen Yu has done a good job of secrecy, the disappearance of 100,000 people, except for the people in the organization who know, the outside world has not heard a trace of wind at all.

When 100,000 people came to the primitive world and began to build the city, the scene was very spectacular, and with so many people working together, Chen Yu felt that it would soon be successful. (To be continued.) )
