These people from the laboratory at Section 1 of Feihua Base were secretly sent to the ground by Xuyou. After a unified interrogation, they were sent to the medical team on the coastline.

The leader of Section 1, because he knew too much, wore a mouthguard to prevent suicide, got trapped and was sent to Xiangcheng by Xuyou's garrison.

Such a leader is to be sent to Qing Xiran for searching his brain, and maybe he can get the whereabouts of the Huang brothers from their brains.

And the rest, the rich and guards may not know what happened in this number segment. They are still immersed in their own debauchery every day. This is their underground world, and they don’t know anything outside, and no one tells them.

Qing Xiran did not disturb the lives of these rich people. They did not know that there was an enhancer in this world. Although the outside world has been baptized by the end of the world, people have now changed their lifestyle and have adapted to sadness within a few years.

The rest, even ordinary people can live for a long time under the action of strengthening agents.

But Qing Xiran did not tell these wealthy people. For these wealthy people, they entered the underground Feihua base to know that they could survive, so they raised funds for the Huang brothers.

They also know what the Huang brothers have done with those smart people with good brains. Even many wealthy people opened companies before the end of the world, attracted a large number of top smart people with generous high salaries, and lured them to the underground Feihua base.

They exchange their own lives for their own death.

Then they don’t have to know how people from outside can live and how they can live. They just need to continue to make fertilizer for plants in the laboratory in this Feihua base.

Speaking of the ecosystem of Feihua Base, Qing Xiran has to admire the cleverness of the Huang brothers. They collected funds from the rich, established this underground base, and raised such a large number of rich people. After eating and drinking, they had to pull out the wastes that were pulled through the underground pipeline and were automatically transported to the soil of the laboratory as fertilizer to raise crops before the end of the world.

Although there are not many people in the Feihua base now, after precise fertilizer distribution, there are many foods that can be produced, which can completely supply the food needs of so many people in the central safe zone.

Qing Xiran can also copy this ready-made and precise fertilizer distribution system and use it for artificial breeding of cannibal plants in the eastern region.

Then Qing Xiran compared the daily crop output of Feihua Base in Section 1, Section 5, Section 4 and Section 3 every year, as well as the number of existing wealthy people in each section, and obtained the total monthly surplus materials of the entire Feihua Base.

She compared the amount of materials input in the central security zone every month and easily came to a conclusion that Feihua Base only supplies the consumption of its own base and the central security zone, and its output is far from the amount of other security zones.

That is, if the Huang brothers have a safe zone in the northern region, the Feihua base will not be able to supply the safe zone in the northern region at all.

In the north, the safe area of ​​the Huang brothers can be self-sufficient?

At least, what Qing Xiran can be sure of now is that this northern safety zone must have its own production system.

So, just count the number of villages in the northern region, and see which village manages the Times Base to buy the least supplies, or even if you have not found the Times Base to buy the supplies.

She silently issued an order to the trading firm and Qu Yang, asking them to register where the people who bought the goods came from when they were selling them, and things should be done more and more. It is said that the north is now winter, and after the breeding season begins next year, there will be more and more mutant monsters.

Times Base plans to open a high-speed rail in the future. If a large batch of materials are ordered in a certain area, the second high-speed rail in Times will be repaired wherever it is.

It's now under investigation.

Of course, whether to open the specific ones or not is going to be done in the future. The second high-speed rail will definitely be opened. If it is registered, there will be more villages buying supplies in which area, and the high-speed rail will also be opened in which area.

But if there are few villages that buy supplies in which area are registered, or even none, then you have to carefully investigate the area.

Qing Xiran narrowed the scope of investigation step by step, and under this situation, the analysis given by Qing Xiran showed that the Huang brothers were not far from their death period.

Wen Jing breathed a sigh of relief when she heard Qing Xiran say this. She folded her hands together and said "Amitabha" to the starry night sky in Xiangcheng, and then she felt relieved.

After a few days, the leader of the laboratory at Section 1 of Feihua Base was sent to Qing Xiran, and the transaction bank and Qu Yang also found out the survey. In addition, she sent a drone to the group of people who fled to Feihua Base from afar, and also gave Qing Xiran direction.

The northern region to the north.

The materials in this area are a little rich, and there are the fewest survivors registered in that area. However, according to the current survivor activities in the northern region, the direction of the northern region to the north is not without survivors.

On the contrary, there are quite a lot of survivors there.

With so many survivors gathering in one place and purchasing less outside, how can they solve their material problems? It must be that there is a mature production and supply system that will make the survivors have no shortage of materials at hand.

Based on this inference, Qing Xiran kept sending drones to the north of the northern region and monitoring the signals of survivors in that direction.

Finally, she precisely targeted a former waste medicinal material factory.

However, Qing Xiran's drone disguised as a fake bird and wandered around the abandoned medicinal materials factory in the sky for several days. Judging from the surface construction, the medicinal materials factory could not see anything at all.

However, the villages built around this medicinal material factory have a certain armed scale. They look larger inside and outside than the villages, and the armed formation is a bit like garrison.

Just as Qing Xiran was planning to touch the details of these villages, Xuyou seemed to have the intention to retract from the ground through observation of this mutated python.

Because the body of this giant python has been staying in the crystal nucleus layer to absorb the crystal nucleus, and its body is getting bigger and bigger. If it wants to force it to leave the ground, it is not impossible.

However, there is no crystal nucleus on the ground to support it.
