The most ruthless person in the apocalypse

It was a cold night, and the population in the Tianmayyu camp doubled, with nearly thirty more people. Two more people had to be arranged to burn the boiler and patrol.

Several chimneys in the camp were smoking in the night, zombie corpses and firewood were burning in the heater, and hot water was flowing repeatedly in the pipes, providing comfortable warmth to everyone in the camp.

The night passed quickly, and the next day was cloudless and windless, but still as cold.

Zhang Su woke up and the first thing he did when he opened his eyes was to focus on the energy tank.

He first focused on the backup energy tank. He was very happy that the first one was full, and the second one had also accumulated more than 80%. In other words, after one night, the backup energy tank was restored to 100%. One hundred and fifty!

This speed made him breathe a big sigh of relief. If he could recover from sleep so quickly, then the cooling time would basically be one day, which was completely acceptable.

But when he turned his attention to his own energy tank, he immediately frowned.

Before going to bed, he clearly remembered that it was 89% at that time, but when he woke up, it was now 93%. After sleeping together for one night, he recovered to 4%?

Zhang Su was puzzled. He didn't engage in any physical exercise or have terrible nightmares before going to bed last night. He slept comfortably under a warm quilt, and his body's energy was only restored to 4%?

Can't understand...

While I was thinking about it, I was packing up, and then something even more incomprehensible happened.

"Xiaoxue measured the temperature last night and found that after the first round of sudden drops, it was not stable and continued to cool down slowly. The lowest temperature last night reached minus 30 degrees, which has exceeded the extreme value in Qincheng."

Zhong Xiaoshan walked in from outside the house, with a strong cold air, and said a little solemnly, and then said: "You are not wearing these enough, wear a real hat..."

After saying that, he took out a thick cotton hat from the closet and handed it to Zhang Su.

Thirty degrees below zero is nothing in the Northeast, which can reach minus 50 degrees, but for Qincheng, it is already considered an extreme cold disaster. When the house was built, it was not considered to be so low, and the cold protection effect will begin. discount.

In addition, many facilities are now paralyzed, which further tests human beings' ability to survive!

The only thing to be thankful for is that it was only dry and cold, without snow, otherwise the situation would have been several times worse...

They don't know that Qincheng is not the only one who is so cold. The entire planet is experiencing the same climate. Under this wave of extreme climate, except for the North and South Poles, which are already extremely cold, the rest of the world has also entered quick-freezing mode...

People who have experienced cold for a long time in high latitudes are okay. Although it is a little more difficult, they will not die from it. However, those who have temperatures above zero all year round, including in tropical areas, do not even have the common sense to deal with the cold. In this wave of cooling, many people are frozen forever.

It cannot be said that there is no such comfortable camp as Tianmay Island. It can only be said that it is extremely rare in the world. If more survivors knew that there is such a safe camp more than 20 kilometers north of Qincheng , I’m afraid I’ll risk it to have a look.

"What a bad weather."

Zhang Su frowned, not understanding what was going on in this world. Facing the crisis of zombies, he had just managed to find a way out, but the cold wave followed closely. As if he was deeply afraid to see human beings living a good life for a few days, he kept going. Rushing to a dead end.

"Husband, I think... we have to bring back more zombie corpses from the Blue Dragon Corps!"

Zheng Xinyu is also wearing something. She still has to go out to work today.

"Yes!" Zhang Su solemnly nodded: "It is very necessary!"

Nowadays, the main energy source for heating in the camp relies on zombie corpses. In the previous temperature environment, it was enough to burn a stove one night and add more than ten kilograms of coal at most. However, in the face of extreme cold disasters, the loss of hot water in the pipes will increase. It rises sharply, and the firepower must be increased. I am afraid that one stove will burn two zombies in one night!

Once there is a shortage of energy, cold will take away people's lives faster than food shortage. In ancient winter, how many people fell asleep at night and never woke up. When the temperature reached more than 30 degrees below zero, three people were "cold to death" Words are no longer about complaints!

Today, Tianmay Island does not have a large inventory of zombie corpses. Fortunately, there are piles of corpses at the barracks, so the carrying capacity is insufficient.

"All the cars are out today, let's go and eat first!"

Zhang Su decided that in addition to transporting the remaining weapons and food from the barracks today, he would also transport as many zombie corpses as possible. Those were valuable fuel, and zombies of the same weight were more resistant to burning than coal.

Little Lucky's restaurant can no longer accommodate more people to dine together, because considering that it will be distributed to other villages, there is no need to open a new restaurant. Everyone who joined the camp yesterday was quietly waiting for the second round of meals. Not only did they not have any complaints, they also Feeling deeply uneasy about being able to eat without working.

"Everyone."

Zhang Su did not leave after eating. He waited for the second round of diners to enter the restaurant and said loudly. Seeing everyone looking at him, he continued: "Do you know why the Qinglong Corps attracted a group of 100,000-level corpses?"

? ?

What a strange question, which made everyone present fall into thinking. Most people were following Zhang Su's train of thought and wondering why. Others like Ma Changshou, Pan Guoliang and others felt a slight thump in their hearts, secretly wondering if the initiator of this incident was... The person who spoke?

"because……"

"Because zombies can sense people."

Zhang Su was about to announce the answer directly. Unexpectedly, Xie Yanshan also spoke. He smiled, raised his hand and said, "Mr. Xie will tell."

"Then I will show my shame..."

Xie Yanshan followed Zhang Su's voice and saw a blurry figure. He nodded embarrassedly, then stood up and said, "Zombies seem to have evolved the ability to sense human magnetic fields. Everyone knows that zombies will slowly gather. When the zombies gather to a certain size, the sensing ability will be triggered, and then they will move towards the survivors' camp and attract zombies along the way."

"We have done many experiments, and we were very lucky to come up with the critical number of zombies that trigger induction, one hundred and one! You will definitely have questions about this number. We did the same at the time. We analyzed a lot, but in the end we only knew, This is an ordinary prime number. If there is anything unique about it, it is the first of the three-digit prime numbers, nothing more.”

"When the corpse group reaches one hundred and one, they will trigger the induction, but not every time it will be triggered just when it reaches this number. The fastest case only took less than half a day, but there are also slow ones. There was an experimental group before, well... more than ten days passed, and until the zombies came, there was no triggering of the induction. There should be some secrets that we haven't discovered yet!"

Xie Yanshan spoke eloquently.

The vast majority of people at the scene were in a state of complete confusion. Many people actually didn’t even understand what prime numbers were. They just listened to it and it felt very awesome.

Zhang Su listened very carefully. He did not expect that the scientific department of the Qinglong Corps had studied so deeply. Although knowing that triggering the critical number could not change anything, it was still an understanding...

"What about the number of people? Mr. Xie, how many people will attract zombies if they gather together? Do you have any data?"

"I'm sorry...the number of people has been increased to twenty, but we have not succeeded in attracting the attention of the zombies. Later, we stopped the experiment with the number of people because we inferred that the attraction phenomenon mainly occurs at the macro level and takes a long time to form. It does not happen overnight. So it is difficult to draw a conclusion. The only thing that can be concluded for sure is that the population size is positively related to the size of the corpse group."

"I'm done."

Xie Yanshan finally made a conclusion before sitting down, as if he was speaking at an academic seminar, quite formally.

After listening to Xie Yanshan's words, everyone looked at each other, especially the folks in Xidaying Village. Most of them had not thought about this issue. Occasionally, a few people noticed it and couldn't figure it out. After hearing such an organized summary, Very surprised.

No one commented, everyone was still very reserved, knowing that the leader still had something to say.

"I have a question."

Zhang Su frowned and said: "Since no conclusion has been drawn regarding the number of zombies, how do you determine that attraction will be triggered when the number of zombies reaches one hundred and one?"

"Oh, yes, I forgot to mention it!" Xie Yanshan stood up again and said: "At that time, we chose a closed experimental environment. When the number of zombies was less than 101, they were scattered and did not form a whole. But when we put The 101st zombies were put into the warehouse, and the group of zombies changed. The zombies began to gather, and then entered the trigger waiting period. It can also be understood that they are performing collective induction, and they will start to move in a certain direction when the induction is over! "

"We thought that the corpses would move towards the most densely populated accommodation area in the barracks. However, we found no pattern after observation. Later, we conducted tests and failed to successfully attract the corpses. What I said was to use a special magnetic field to attract. It’s not about making sounds to attract people directly, please don’t misunderstand me, I’m done.”

Xie Yanshan sat down again, very politely.

"So that's it."

Zhang Su nodded thoughtfully and continued: "Mr. Xie's research direction is consistent with our attraction theory. The more people there are, the larger the corpse group will be attracted. It is already freezing cold, so I plan to let some people in after the spring. I moved to Madianzhuang, but now that Tianmay Island is overcrowded, I decided to start the satellite village plan in advance!”

After everyone knew that more people would attract more zombies, they all nodded in agreement with Zhang Su's plan.

Zhang Su pointed at Ma Changshou and said: "Village Chief Ma, today..."

"There is no village chief, Boss Zhang. If you call me "Lao Ma" from now on, you will be promoting me. You will never be the village chief!"

Ma Changshou interrupted Zhang Su's words slightly rudely, but the meaning he expressed was very favorable.
