After determining that Ji Cheng had the strength to protect them, Xuan Tianxing went back and brought up half of the population of the dungeon, most of them were women and old people, but because of the revival of the aura, these women and old people also had the strength of martial artists, and the limit was five hundred catties of arm strength. It is enough to do urban construction, and with the cooperation of some machinery and equipment, the construction will not be slow at night.

And Ji Cheng took Dabai and apes into the mountains and forests, and subdued all the demon beasts in a radius of tens of thousands, so that humans could enter the mountains and forests to collect resources and minerals.

In order to speed up the construction and mining of the materials needed to build the city, Jicheng also asked some demon beasts to cooperate with humans, and strive to build the city as soon as possible.

A few days later, Xuan Tianxing brought the harvested resources back to the dungeon and began to awaken the sleeping genius, and one of the two martial kings of the dungeon came to the ground to supervise the construction of the city, and to monitor these demon beasts and protect the humans.

After all, Ji Cheng had to clean up the mountains and forests within a radius of tens of thousands of miles, and he didn't come back so quickly, so he needed a strong man to sit in order to prevent these demon beasts from rioting.

More than two months later, Ji Cheng finally returned, and he brought dozens of larger demon beasts, basically at the fifth to seventh levels, each carrying various medicinal herbs and spiritual fruits on their backs.

In more than two months, the new city has been cone-shaped, the city walls have been almost built, several high-rise buildings have been built, and the people in the underground city have basically come out.

The new city covers an area of several hundred square kilometers, and 100,000 people is nothing at all, so an inner city was built. Seeing Ji Cheng coming back, Xuan Tianxing came out with two martial kings to greet him in person: "Welcome your seniors back to the city." ”

Ji Cheng: "You're welcome, this is the resources I brought back for you, you make good use of these resources to improve your strength, and I will leave when your strength is enough to protect yourself." ”

Xuan Tianxing: "Senior, where are you going?" ”

Ji Cheng: "There must be dungeons like you before, and they need help too, so I can't stay here forever." ”

"The seniors are high-minded, and the juniors will definitely urge everyone to cultivate, and have the power to protect themselves as soon as possible, so that the seniors can take time out to help others as soon as possible."

After listening to Ji Cheng's explanation, Xuan Tianxing could understand, although he really wanted Ji Cheng to stay here all the time, but it would be very selfish to do so. There are still countless compatriots in need of help, and if they are not capable, they cannot be held back, so what he said is the truth from the heart.

Ji Cheng: "In order to improve everyone's strength, in addition to bringing back resources for everyone, I will take some people into the mountains and forests to experience, only fighting is the best shortcut to improve strength." ”

Xuan Tianxing: "Senior, you can rest assured in this regard, although we have not gone deep into the mountains and forests to fight against demon beasts, we will not have less combat experience. We have a simulation game with a sense of realism that is 80% real, and as long as you have time, you will go inside to find an opponent to improve your combat effectiveness. ”

Ji Cheng shook his head and said: "No matter how real the simulation game is, it is still a game, and it will never be able to replace the real experience, and you don't know enough about the combat power of demon beasts."

Some monsters can breathe fire, can produce repulsion, psychedelic enemies, explode instantly, and hide talents.........

Even if you have encountered it in the game, it is not as good as what you have encountered in reality, and in reality you will die and cannot be reborn. I take them to experience and find opponents based on their strength, and I won't save people. Everything can only rely on yourself, if you are really defeated by the demon beast, you can only blame yourself for being useless. ”

"I dream of understanding the hardships of our predecessors, and we will not let our predecessors down, now is not a peaceful and prosperous world, crises are everywhere, and it is normal to be eliminated without strength, and we will not blame our predecessors for this." Xuan Tianxing is telling the truth, if the opponents of the same level can't win, then it will be even more difficult for the human race to rise again.

Although the revival of aura has given some of these demon beasts spiritual intelligence, not all of them have the same high IQ as humans. Humans have enough resources, and their minds can't win, and these beasts really can't be justified.

"Don't think I'm cruel."

"Of course not...! Senior, you have worked hard for a few months, and I will take you into the dungeon to rest......"

"I don't need to rest, I just want to see what the dungeon is like."

Last time, Xuan Tianxing didn't invite himself into the dungeon, and he couldn't talk about it, but now that Xuan Tianxing invited himself, he could just go down and have a look.

Then Xuan Tianxing took Ji Cheng into the dungeon, the dungeon is thousands of meters underground, and there is a sunlight simulator inside, although it is not as good as the sun's sunlight, but it can also allow plants to grow normally, produce photosynthesis to provide oxygen, even if the entrance is closed, there is no need to worry about lack of oxygen.

Ji Cheng felt as if he had returned to his previous life, familiar with the buildings, transportation, and streets. Except for the lack of food, the dungeon is no different from what it was back then.

Then we come to the core area, which is very different from the previous slums, where the means of transportation are more advanced, and the various scientific products are like those in the science fiction movies of the previous life.

"Because half of this place was destroyed in the first place, otherwise we would not be short of food, and the dungeon we originally built was a small and complete ecosystem, but unfortunately it was destroyed a lot of planting and pastoral areas.

We've been a mecha for a long time before, but it's a pity that the materials are lacking, and we can't make a mecha that can resist a third-level demon beast or above. However, now that there are enough materials and new types of energy, a mecha that can be compared to the strength of a fourth-level demon beast has been made. In other words, an ordinary martial artist can also fight against a fourth-level demon beast when he puts on a mecha.

Next, our research will be on the fifth-level demon beasts, but the fifth-level demon beasts are very different from the fourth-level demon beasts, and they can't be studied in a short time. But we'll try to research it out before you leave, so you can take some with you. ”

Xuan Tianxing took Ji Cheng to the experimental base and explained various scientific and technological products to Ji Cheng, as well as some scientific and technological weapons.

There were weapons that could deal with fourth-level demon beasts before, but because of the lack of energy and materials in this area, there was no mass production, and now you can enter the mountains and forests, find the corresponding minerals and energy minerals, and start mass production.

"When technology was so advanced, didn't you make a spaceship to leave the earth and find a new planet of life? Or build a space city. ”

After looking at the dungeon, Ji Cheng came to the conclusion that this seems to be a city made of steel, and they will lack materials to build weapons because of the countless resources used to build this dungeon.

Since you can build a dungeon, it's not difficult to build a space city, you can simulate sunlight to photosynthesize plants and release oxygen, and humans will not have any problems living normally in it.

But why would they rather build so many dungeons than build them? This made Ji Cheng puzzled. Take a look at the latest chapter of "Reopening Hell: The Rise of the Ten Thousand Worlds Claw Book House" to read it for free for the first time.
