At night, the snow fell a little heavier than yesterday. Xiangcheng had never been colder like this, but it was okay. Qing Xiran had already instructed the trading bank and the mission center to unite and collect a large amount of winter supplies. If the people in Xiangcheng who felt cold, they could go to the trading bank to purchase winter clothes at any time.

If there are frozen bones on the road, it is impossible to appear in Xiangcheng.

But there are some necessary hidden dangers. Now we must consider that since Xiangcheng this year is colder than in any previous year and the temperature has repeatedly set the lowest record of Xiangcheng, it is not certain whether Xiangcheng this year will continue to be cold.

At present, the power supply in Xiangcheng has been restored. In places 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 not cold, it is very good for every household to have an air conditioner that can make heating.

It’s so cold that I can’t stand it. After the coldest days when I turn on the air conditioner, I will soon be in spring.

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

This number continues to rise.

Therefore, the basic circuit facilities are already in aging in Xiangcheng. Due to the surge in population, electricity consumption in winter has caused excessive loads in many places. Power outages are everywhere inside and outside Xiangcheng. Although the overloaded circuits will be repaired quickly every time, this is not a long-term solution.

But Qing Xiran also has her own solution. She recently discovered a lot of fresh things in the BBZ Heavy Industry network. Although the detailed technology is kept at the headquarters of BBZ Heavy Industry and she has not had the opportunity to explore the headquarters of BBZ Heavy Industry, but the network of BBZ Heavy Industry in Longshan gave Qing Xiran a lot of information.

For example, the construction drawings of the safe zone, the construction principles of the entire safe zone, and the installation locations of some new technologies.

Among them is a new technology called crystal core energy converter.

She had heard Yuyou talk about it before. The above began to study the energy of the crystal nucleus a long time ago. It may extract energy from the crystal nucleus for other purposes to ensure that people still have a continuous use of energy underground.

This time Qing Xiran's virus bbz Heavy Industry implanted in Longshan network, which made Qing Xiran directly affirm the existence of this technology. In other words, the energy in the crystal nucleus can not only satisfy the superpowers, but also be used to restore the superpowers in the superpowers, but can also be converted into electrical energy, which is sent to various types of machines, filtering water quality, purifying air, transporting oxygen, etc.... all rely on this energy converter.

So this energy converter is a big treasure.

But Longshan's bbz Heavy Industry is just a branch of bbz Heavy Industry. The detailed drawings of the energy converter and the energy conversion principle are all sealed at the headquarters of bbz Heavy Industry, that is, the central security zone.

The initial plan for the construction of these safety zones was as follows: the establishment of a very large safety zone in the middle will connect to four medium-sized safety zones, east, west, south and north, and these four medium-sized safety zones will connect to several small safety zones.

The medium-sized security zone is composed of several small and small security zones. The Longshan security zone belongs to one of the medium-sized security zones in the south, and belongs to the medium and small category.

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

Therefore, from the beginning, in order to occupy a leadership position in the future and continue to become an underground command center system, it is impossible for their core technology, that is, the technology of crystal core energy conversion, to be transmitted to other safety areas. This energy converter was completed and distributed to various small and medium-sized safety areas in the BBZ Heavy Industry Headquarters in the central region.

This kind of energy converter cannot be disassembled, and there are self-destructing devices inside. Once you want to remove them manually, it will cause a self-destructing system.

Therefore, when the Longshan Security Zone is blocked by Gu Yu, the crystal core inside will be cut off, and the desperate situation of the Longshan Security Zone being isolated will appear.

At the iron gate, Xuyou, who had a cold face, and Qing Xiran finished listening to Xiaolongbao's words. Before Xuyou could speak, Qing Xiran frowned slightly and asked Xiaolongbao outside the iron gate.

"The safe area needs to stop oxygen supply, is this news sure?"

"Confirm, Li Xiaoxing said it in person."

Xiao Longbao was also anxious, otherwise he would not have wanted to risk his life to report to the boss at the middle of the night. He really called the boss's cell phone, but he didn't answer it, and it was also related to his grandmother. Xiao Longbao couldn't come and disturb the boss.

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

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

"The safe area won't let you enter easily. Gu Yu has been in Longshan for so long before he sealed the safe area, which means that the door of this safe area is really difficult to enter."

Qingxi shook her head. This situation was beyond her expectations. Who knew whether Li Xiaoxing was saying true or false? The crystal core reserves in the safe area were only a little bit, only enough for one week to use. Is this possible?

The entire security zone is wrapped in a huge crystal core layer. If it is really time to end, it is not impossible to dig a little crystal core in the crystal core layer for use.

Even if bbz Heavy Industry doesn't do this, will the district mayor in the safety zone not do it if he is forced to do it?

She turned her head directly, answered the call with Liu Ye, and told Liu Ye what Li Xiaoxing said in the safety zone.

Sixth Master has been in the safe zone and has done something shameful to all forces. But this is the first time I heard about this news. I don’t care whether what Li Xiaoxing said is true or not. Her words are taught by the safety zone, and the purpose is to use her to help Xuyou.

But there are many news in the security area, and people inside the security area do not know it, and the messages transmitted to the outside are absolutely different from those inside.

After hearing Qing Xiran's words, Master Liu pondered for a moment on the other end of the phone and said seriously:
Chapter completed!
