At night, the snow fell a little heavier than yesterday, and Xiangcheng had never been so cold, but it didn't matter, Qing Xiran had already ordered the trading bank and the task center to join forces and collect a large number of winter materials.

There is such a thing as frozen bones on the road, and it is impossible to appear in Xiangcheng.

However, there are some necessary hidden dangers, and now we must also take into account that in view of the fact that this year's Xiangcheng is colder than any year in previous years, and the temperature has repeatedly refreshed the lowest record in Xiangcheng, it is not certain whether this year's Xiangcheng will continue to be cold.

At present, the power plant in Xiangcheng has restored the power supply, in a place like Xiangcheng, it is impossible for every household to use heating, and there is no basic heating equipment in the north, because the winter in Xiangcheng is not long, and it is not cold, so it is very good for every household to have an air conditioner that can be heated.

It's really cold and unbearable, turn on the air conditioner for a few days to survive the coldest days, and it will soon be spring.

But because it was too cold this year, everyone turned on the air conditioner very early, and because of the arrival of the people of H City, the population of Xiangcheng began to skyrocket, and Xiangcheng, which had only a population of 5 million before the end of the world, experienced a year of apocalypse, and the population soared to about 6 million.

This number continues to rise.

As a result, the basic circuit facilities are already aging in Xiangcheng, because of the population surge, the winter electricity has caused many overloaded circuits, and there will be power outages inside and outside Xiangcheng, although the overloaded circuits will be repaired quickly every time, but this is not a long-term solution at all.

But Qing Xiran also has her own solution, she recently found a lot of new things in the network of BBZ Heavy Industries, although the detailed technology is kept in the headquarters of BBZ Heavy Industries, she has not had the opportunity to explore the headquarters of BBZ Heavy Industries, but in the network of BBZ Heavy Industries in Longshan, Qing Xiran has been given a lot of information.

For example, the construction drawings of the security zone, the construction principle of the entire security zone, and the installation location of some new technologies.

Among them is a new technology called the crystal nucleus energy converter.

She had also heard Xu You say that she had been researching the energy of the crystal nucleus for a long time, and it was possible to extract energy from the crystal nucleus for other purposes to ensure that people still have a steady stream of energy in the ground.

This time, Qing Xiran's virus BBZ Heavy Industry was implanted in the Longshan network, so that Qing Xiran directly affirmed the existence of this technology, that is to say, the energy in the crystal nucleus can not only satisfy the ability of the person with the ability to restore the ability in the body, but also convert it into electrical energy, which can be transmitted to various types of machines, filter water quality, purify the air, deliver oxygen, etc...... It's all about this energy converter.

So this energy converter is a big baby.

However, BBZ Heavy Industries in Yongsan is only a branch of BBZ Heavy Industries, and the detailed production drawings of the energy converter and the energy conversion principle are sealed in the headquarters of BBZ Heavy Industries, that is, the Central Security Zone.

The initial plan for the construction of these security zones was as follows: to build a very large security zone in the central part of the country, which would connect the four medium-sized security zones in the east, west, south and north, and these four medium-sized security zones would in turn connect to the remaining small security zones.

The medium-sized security zone is composed of several small security zones, and the Yongsan security zone belongs to one of the medium-sized security zones in the south, which belongs to the category of not being large or small.

Its future goal is to expand and integrate with several other local security zones after the completion of the construction of several small security zones to form a medium-sized security zone in the south, and then connect with the large security zone in the middle to form a huge underground society.

Therefore, from the very beginning, in order to occupy a leading position in the central security zone in the future and continue to become an underground command center system, it is impossible to let their core technology, that is, the technology of crystal nucleus energy conversion, spread to other security zones.

This kind of energy converter cannot be disassembled, and it is equipped with a self-detonation device, and once you want to dismantle it, it will trigger a self-detonation system.

Therefore, when the Longshan safety zone is blocked by Gu Yu, the crystal nuclei inside are cut off, and there will be a desperate situation where the Longshan safety zone is isolated.

At the iron gate, Xu You, who had a cold face, and Qing Xiran listened to Xiao Longbao's words, Xu You didn't speak yet, but Qing Xiran frowned slightly, and asked Xiao Longbao outside the iron gate,

"The oxygen supply to the safe zone is going to be stopped, is this news confirmed?"

"Sure, Li Xiaoxing said it himself."

Xiao Longbao is also in a hurry, otherwise he doesn't want to risk his life in the middle of the night to report to the boss, he really calls the boss's mobile phone, he doesn't answer, and it's about the grandmother of one by one, Xiao Longbao doesn't come to disturb the boss.

Xu You put down the knife in his hand, looked back at Qing Xiran, and said:

"I'll take someone to the north immediately and rescue our mother first."

"The security zone will not let you enter easily, Gu Yu has been active in Longshan for so long before the security zone has been sealed, which shows that the door of this security zone is really difficult to enter."

Qingxi shook her head, this situation was unexpected by her, who knows if what Li Xiaoxing said is true or false, the crystal nucleus reserve in the safe zone is only so little, only enough for a week, is this possible?

The entire security zone is encased in a huge crystal nucleus layer, and it is not impossible to dig up a little crystal nucleus in the crystal nucleus layer if it is really at the end of the mountain.

Even if BBZ Heavy Industries doesn't do this, the head of the security zone will not do it if he is forced to do it?

She directly turned her head, connected the call with the sixth master, and told the sixth master what Li Xiaoxing said about the safe zone.

The sixth master has always been in the security zone, doing some shady things for all forces, but this news is the first time I have heard of it, and it doesn't matter if what Li Xiaoxing said is true or not, her words were taught to her by the security zone, and the purpose is to use her role as Xu You.

But in the security zone, there is a lot of news, people inside the security zone do not know, and the news that spreads outside is absolutely different from the inside.

Hearing Qing Xiran's words, the sixth master muttered for a moment on the other end of the phone, and said very seriously:

"The security zone is indeed blocked by Gu Yu now, and none of the people inside can get out, but Gu Yu can't come in, and the district chief didn't say that our energy will be exhausted within a week, probably to maintain stability, so if it spreads, I'm afraid the security zone will be chaotic."
