This helicopter is the oldest model, without any high-tech equipment, no high-tech equipment, no wireless guidance, and cannot accept satellite signals. It works like an old-fashioned tractor – burns oil and then takes off.

In the world of red fog that blocks a qiē radio signal, sometimes old-school things work better than newer equipment. Of course, in order to cater to this harsh environment, these helicopters have also undergone some special modifications. The front windshield has been dismantled - after all, in such a thick fog, there is a windshield that will be instantly pasted - except for Lao Liu's octopus machine, basically it is rare to see a mechanical installation with a windshield now

In addition to the helicopter's windshield being removed, the pilots inside are also carefully selected by the military and have the best eyesight. They are an alternative kind of augmented people, belonging to the sensory augmentation, and their eyesight is much better than that of ordinary people - in the world of red mist, only these people can have the ability to fly a helicopter.

Of course, in addition to their own good eyes, they also wear special goggles, which allow them to see farther distances.

After these specially modified old helicopters took off, they sprayed special "pesticides" along the pulled grid in a zigzag shape. Helicopters don't dare to fly too high, because higher in the sky, is the world of flying creatures and air carriers, these old helicopters have no ability to compete with them for air supremacy, can only fly at a height of tens of meters, close to the ground at a low altitude, and the flight altitude is not even as high as those higher floors.

But even so, even if it is old, even if it is timid, but after all, it is an airplane. It was not difficult for the helicopter to fly all over the city, and after a few hours, the first round of spraying of the inner city was complete. And after those aerial sprays fell to the ground, those originally manic cockroaches slowly quieted down, did not explode pre-death poisoning, and did not make the last struggle, this thing seems to be really the nemesis of those cockroaches. After being sprayed with pesticides, the body began to stiffen, and the mobility of the river began to decline, and from the air, the black "river" flowing between the streets suddenly slowed down, and then became slower and slower, slower and slower, and finally the river finally stopped moving as if it was silted up.

Early the next morning, Li Qing was invited by Lao Liu to open the door of the real yàn room and walk out of the street, and saw rows of troops on the road, wearing protective clothing and disinfectant masks, burning the corpses of the cockroaches on the street while cleaning, and there were still no pedestrians on the street, and the corpses of cockroaches on the ground were swarming

Li Qing bent down to pick one up, and after being touched by the outside world, the cockroach's legs could still move slowly and stiffly a few times, but it was not far from death - let alone any threat.

"This is made by Li Qingshui, and he is officially preparing to enter the high-level." Lao Liu said.

"To be able to take the first step, with his ability, it is very easy to go up."

"When are you going to act?"

"The sooner the better, when Ding Kun wakes up, we will go out, there is no point in staying here." Li Qing said: "Our first stop is Jinan, Shandong, and there should be more news in the provincial capital city in the apocalypse. We have to borrow external forces, only in this way can we fight with Li Qingshui. ”

"Well, that's all I can help with your business." Lao Liu said: "If there is anything else to explain, then I can only tell you, there may be a cold wave ahead, and the weather will become very cold." ”

"Cold? Is it almost winter? Li Qing felt the temperature of the outside world with the palm of his hand, his touch is very keen now, and he can intuitively feel that the current temperature is about 1o degrees, which is relatively cold, but it is not cold. In the winter of Beijing, it can generally reach minus 7B degrees, and even in the cold winter, it can reach minus 20 degrees.

"I'm not talking about this cold, it's something like the coming of the Cambrian cold wave."

"Cambrian cold wave?" Li Qing had heard this word for the first time, and he was sure that when he read similar books before, he had never had a similar word like this one at all.

"Well, the word is what I know, and then I say it. The current world is the second coming of the Cambrian period, and you already know this. The Cambrian period is the explosion of life on the earth, almost all middle and advanced life began in that time period, which lasted 2oo million years, and the life history of our earth jumped directly from a single-cell history to a higher life history. Two million years is much more than billions of years. But again, two million years is a snap of a finger compared to billions of years, but compared to the second Cambrian period, it seems much longer. ”

"Although I'm sure that the fog that came to Earth last time was definitely not as thick as it is now, but again, don't you feel that this time the progress is too fast? It has only been a few years since the end came, not to mention two million years, two hundred years or even twenty years, and the life of the earth has exploded like this in just a dozen years, every day, even every hour and every minute, new species are born, and the original species are either eliminated or evolved into something more powerful. ”

"Isn't that because there's more base?" Li Qing guessed, "In the past, it was a single cell, with a small base and small changes. One to ten is a tenfold increase, ten thousand to a hundred thousand, also a tenfold increase, and our biological base is more than at that time. ”

"You're right, it was really because of the cardinality problem in the early days. But then, at the height of the Cambrian period, there were much more species than they are now, but according to fossil research, many of the higher life at that time, that is, life that was much higher than the evolutionary process of that period, also died, not only as a result of the biosphere's own selection, but also because of the weather. The law of the world is like this, the explosion is not long-lasting, and the flame of the bomb, although brilliant, does not last as long as firewood. ”

"Just say what you want to say, I roughly understand what you mean."

"yes, okay." Lao Liu nodded, and no longer talked nonsense, "There is another natural screening after the biological explosion, according to my research on the geological layer at that time, the existing fossils are frozen, but the frozen location is the tropics." Therefore, the first screening result of the bioexplosion is the internal elimination of the biosphere, and the second screening is due to climatic reasons. It may be that he is afraid of breaking out problems, so he naturally formulated this kind of rule, and after the biological explosion, there will be a more violent cold wave. ”

"When is the cold wave coming?" Li Qing asked.

"Just a few days, the temperature is going to get very cold."

"How cold is it?"

"It's a few tens of degrees below zero, I don't know the specifics."

"Then there will be even more food shortages." Li Qing suddenly thought of this, "In the weather of dozens of degrees below zero, it will be very difficult to grow food again." And when the animals freeze to death or hide, hunting in the wild will become more difficult. ”

"Yes, then there will be another wave in Beijing, which will be more terrible and lasting than the cockroach wave - people will lose food." Lao Liu said: "Although we don't have to worry about food, it will be difficult for ordinary people to get food, and Li Qingshui will take advantage of this turmoil to go one step further." He'll be the first to get the hardy food, and the clone and I stay here to give him some restraint. After all, monopoly is the most competitive way to gain a foothold, and even if we develop similar crops after him, it is better than letting him dominate alone. Otherwise, if he has mastered the food, it is like mastering the hearts of the people, the army, and the legions, and he will complete the final breakthrough. ”

"I see." Li Qing nodded.

"Also, you must be careful of Liu Chang on the road, he may find trouble for you. After all, here, there are only three of his targets, you, Li Qingshui and the girl named Xiaojing in the house. With me and the clones here, Li Qingshui can't find us, and Liu Chang is even more impossible, and he doesn't dare to go to Li Qingshui at all, so the target is only one of you. ”

"Yes." Li Qing nodded again, "What else do you have to explain?" ”

"It's gone." Lao Liu patted Li Qing's shoulder, "Take care." ”

Over the next two days, the weather got colder and colder. Few people paid attention to it except those in the know - everyone thought it was winter coming.

In the past two days, there have also been great changes in Beijing, Li Qingshui was commended by the upper echelons, and won the highest honor together with the research institute. In the research institute, Li Qingshui, whether it is popularity or voice, has already faintly passed the principal Li En.

In the apocalypse, ability comes first, and not only that, Li Qingshui is very good at being a person, and among all the people he comes into contact with, except for Li En, he has a good reputation for him - this seems to be a perfect person who will not be a little arrogant even if he wins more honors, and no matter how great his ability is, he can always do every little thing around him.

There's no one who doesn't want to be friends with someone like that, and there's no one who doesn't like to work with someone like that.

Therefore, in addition to specific events, Li Qingshui's hidden connections, like the underground veins of willow trees, spread to the whole city little by little. Moreover, many of them secretly pushed the people, either out of personal respect, or at the instigation of Li Qingshui, to inform the ordinary people of the biggest contributor to the cockroach incident, and in addition to the high-level officials in Beijing, more and more civilians and refugees know the name "Li Qingshui".

The momentum of the huge waves has accumulated little by little, and when it sweeps over, it will be overwhelming.

Of course, these things are not what Li Qing is most concerned about. The life or death of human beings in this world has little to do with him, he wants to know these things just because it is related to the mission.

The next night, Ding Kun woke up, and there was really something more on his body--on his hands, there were a lot of black things like bursting green tendons, which could squirm and deform.

"It looks kind of disgusting." That's how Zhizhi commented when I first saw him.
