Dr. Qin is a scientist who studies biological genes, and I don't know if he has any research in other areas.

Then Ning Qiu took him aside alone and asked, "Doctor, do you know if there is any technique that can make people fall asleep, and then keep stopping the metabolism of Xincheng in the body until two hundred years later. ”

He didn't directly say that he would be sealed for three days, but asked tentatively first.

"Sleeping?" Dr. Qin frowned, lost in thought.

Seeing this, Ning Qiu couldn't help but have some expectations in his heart, since Dr. Qin was thinking, then it meant that there was still this technology.

It took about two minutes before Dr. Qin spoke, "Ice." ”

"Frozen?"

"Yes, ice is the only way to put people to sleep right now." Dr. Qin said.

"Then Dr. Qin, did you do it?" Ning Qiu asked.

Dr. Qin shook his head and said, "I know an American professor who specializes in this kind of technology, if it is a peaceful era, I can introduce you to him." But now, hey, it's one thing whether he's alive or not. ”

Ning Qiu frowned slightly, and said, "As long as there is a glimmer of hope, I am willing to try, and I can go to North America again." ”

Dr. Qin was puzzled and asked, "Why do you want this technology?" ”

You know, this technology is generally used in medical technology.

For example, if a person has an incurable disease, but it cannot be cured with current medical technology, he is frozen in ice.

In the future, when medical technology is developed, this terminal disease can be cured, and then people will be thawed.

However, there is a very high risk associated with doing so.

Because you can't be sure that after you've been frozen in ice, you'll be safe and sound when you wake up again.

Scientists have also theorized that the longer a person is frozen, the higher the chance of accidents.

For example, when he wakes up again, it may cause amnesia.

Or due to prolonged inactivity of the musculoskeletal body, resulting in muscle necrosis and becoming vegetative.

The worst-case scenario is, of course, that you can't wake up and freeze to death in the years.

Dr. Qin also told Ning Qiu about these risks, but Ning Qiu insisted on trying it once.

"Who are you going to freeze?" Dr. Qin asked.

"A friend of mine, a very important friend." Ning Qiu said.

"Is it the weak-looking woman?" Dr. Qin immediately guessed.

Ning Qiu didn't speak, just sighed deeply.

Dr. Qin raised his hand and pointed to his left eye and said, "I was blind to this eye because of a test, and then I installed a mechanical eye that can directly see the fluctuations of cells in the human body. I know none of you are ordinary people, and that woman is very dangerous. However, I still want to advise you that the human ice sealing technology is not yet mature, and it is best not to try it lightly, otherwise you will regret it. ”

Ning Qiu nodded and said gratefully, "Thank you, Doctor, for the reminder, but I have made up my mind." ”

So, Dr. Qin told him the address where he studied human ice sealing technology.

However, although Dr. Qin knew each other, he was not particularly familiar with each other.

And the address he wrote to Ning Qiu was also the address of two or three years ago, as for whether the expert changed the address later, or whether he was eaten by zombies, it is unknown.

"Oh yes, doctor, give this thing back to you, I don't need it anymore." At this time, Ning Qiu took out a bright red bead and handed it over.

Dr. Qin was stunned, but he didn't expect this guy to actually return Angela's corpse core to him.

"I wanted to change something, but in the end I realized that I couldn't change anything. I'll give you back this core, I don't need it anymore. Ning Qiu said.

He just wanted to freeze for three days now, then go back two hundred years and wake up for another three days.

Therefore, he doesn't care whether the corpse core will be obtained by the empty guard in the end.

……

Ning Qiu told Jiang Ling and Pang Xiaobo about the matter, and after two days of cultivation, he was ready to set off.

Knowing that Ning Qiu was leaving again, Song Shengyu found him.

"Can't you go if you don't go?"

"No, I have something very important to do." Ning Qiu shook his head and said.

"The end times are coming, what important things can you do?" Song Shengyu said.

"Well, I can't understand it to you, it's a very important thing anyway."

Song Shengyu was disappointed in his heart, lowered his head, and looked at his toes.

After a long time, he whispered, "You're going to leave forever one day, aren't you?" ”

Ning Qiu sighed and nodded.

Song Shengyu is a good girl, although he likes it very much, but after all, he can't keep her by his side forever.

Song Shengyu lowered his head, tears fell one by one, and fell to the ground.

Ning Qiu was a little embarrassed, and wanted to hug her in his arms and comfort her, but after thinking about it, he still didn't do it after all.

Long pain is better than short pain, let her die early.

At this time, Song Yiting was standing on a building in the distance and happened to see this scene.

She sighed deeply, a wry smile rising into her mouth.

In fact, she only knew that with her and Song Shengyu's charm, she couldn't keep that man at all.

He was too powerful for even the two sisters combined.

……

The next day, Ning Qiu and the four of them set off again and headed for a place called Grizzly City in the United States.

Upon arriving at their destination, they found that the city appeared to be garrisoned by military troops and that a human safety zone had been established.

After finding a place to land, the four of them walked into Grizzly City.

Probably because there were so many survivors in the city, a tide of corpses had formed on the east side of the city at this time, and the roar of artillery could be heard in the distance.

And their human safety zone is set up in the city, and it is built in the streets.

That's a great way to do it.

Because there are many buildings in the city, even if the zombie tide hits, it can only move along the street, and there will be no dense whole area.

Because the building could have formed an obstacle to the tide of corpses, and then it was easy to defend by taking advantage of the terrain.

But that's just for now.

As far as Ning Qiu knows, with the withering and mutation of plants, soil erosion around the world is serious, and various natural disasters will occur in the next two or three days.

Such as earthquakes, typhoons, tornadoes, volcanic eruptions, and so on.

Therefore, establishing a safe zone in the middle of the city is not a long-term solution.

Once there is a mega earthquake, it will undoubtedly be a disaster for the people living in the city, and I am afraid that it will be more terrible than the arrival of the corpse tide, after all, some natural disasters are irresistible to human beings now.

"It seems that there are quite a few survivors, and the probability of that expert surviving is very high." Pang Xiaobo said.

Since the corpse tide was coming from the east at this time, the four of them quietly entered from the west.

Although the high wall of isolation was seven or eight meters, it could not be difficult for them, and they easily entered with a jump.
