"Zi Ming! What are you looking at?" cold beauty found that Lu Zi Ming's eyes were wrong. She looked in the direction of Lu Zi Ming's eyes and saw nothing.

"Nothing. Maybe I'm too worried.". Lu Ziming shook his head, looked away from a pile of ashes and said, "you sleep tonight, I'll guard!"

Lu Ziming didn't say it was OK. When he said it, Rehmannia jumped up like a needle in his ass, "team Lu! Don't scare me!"

"That night you come to guard, I sleep with cold beauty!"

Rehmannia shook his head and said, "Lu team is still on guard. Let me go to bed!"

"Coward! It's embarrassing to have such a timid evolutionist!" the cold beauty scolded with a smile.

"Cowards are cowards. What's wrong with being timid? You should be careful and don't make mistakes. Only in this way can you live longer," said Rehmannia glutinosa with justice.

"Don't be paranoid. I'm just not at ease. I'm responsible for guarding at night. If something really happens, you can't run. Go to bed!"

Seeing the two people return to the car to rest, Lu Ziming goes to a pile of ashes, reaches out his hand, grabs a handful, puts it under his nose and smells it. His eyebrows wrinkle deeper.

What was expected didn't happen. I spent the night in peace. Nothing happened, not even a mutant creature appeared.

"Lu team! Where are we going today? Don't we go back to Chiyou space?"

"There are several research institutes around the suburbs, let's go and have a look!" Xincheng is not a big city, and there are only four or five research institutes that can be called. If there are not a large number of zombies in the urban area, I really want to break in and look for them.

A group of three people drove around the suburbs of Xincheng and began to turn around. The next destination was not far away, but there were many zombies along the way. Coupled with the traffic jam along the road, the speed was frightening. They didn't reach the destination until the afternoon.

"Eh! What's going on?"

Lu Ziming doesn't have to say that cold beauty and Rehmannia glutinosa have found something wrong. There are no people, no mutated organisms, and even a corpse. There are no instruments and equipment in the room. If there is no sign of a scientific research institute hanging at the door, would you think you're in the wrong place?

"Someone has been here before us? Judging from the residual dust, the time is about a month."

This time Lu Ziming didn't say a word. His eyes were still looking around for something. Soon he found some white ashes in the corner, aisle, stairs... And carefully put some ashes into plastic bags.

"Let's go to the next target!"

Late at night, the three finally arrived at the third destination. This time, they were not surprised. The situation was the same as expected. There was nothing. It was as clean as washed, and even the blood stains on the wall were hard to see.

"Lu team! Do you want to keep looking?"

Lu Ziming thought about cableway: "no, we'll return to Chiyou space early tomorrow morning?"

"Zi Ming! Did you find anything?"

Lu Ziming said noncommittally, "maybe. You'll know when you go back?"

The next evening, the three returned to Chiyou space. Lu Ziming handed several plastic bags to Zixin and said, "help me test what's this?"

Half an hour later, Zixin appeared in front of the three and said mysteriously, "master, where did you find those things?"

"Did you find anything in several scientific research institutes?"

"Does the master want to know where the people in the scientific research institute have gone?" Zixin shook with a plastic bag and said, "here is the answer the master is looking for?"

"Do you mean those people have turned into ashes?" Lu Ziming was shocked and quickly reacted to what Zi wanted to say.

"Strictly speaking, it's not ash, it's a return to the origin of carbon compounds!"

Lu Ziming was still confused: "what is the origin of carbon compounds?"

"Master, strictly speaking, the chemical composition of human beings is very simple, 65% water, and the rest is C, h, O, s, N, P, CA, Fe, Zn, etc.. Let's explain that an adult weighing 70 kg has only 25 kg left after dehydration, including 3 kg of carbon hydrate, 7 kg of fat, 12 kg of protein and 3 kg of mineral salt. If he is dehydrated for the second time, there will be 25 kg left Only carbon compounds and minerals will be left, and the weight will not exceed five or six kilograms, and it is these carbon compounds and minerals that the owner brings back! "

Cold beauty and Rehmannia both reacted. At first, they found Lu Ziming studying the white ash on the ground. Later, they saw Lu Ziming put the white ash into a plastic bag. Everywhere Lu Ziming paid attention not to the materials in the room, but to the scattered white ash on the ground.

Lu Ziming didn't find anything strange about these ashes at first, but after checking all the rooms, he suddenly realized that he had neglected something that seemed unimportant. If it is normal to have white ash in the yard and corridor, there is no explanation for the large amount of white ash in the closed laboratory. Lu Ziming also found a large number of dried blood stains on the wall, indicating that there had been corpses here. At least there should not be a corpse invisible here.

"Is there any way to turn corpses or mutant organisms into the so-called source of carbon compounds?"

Zixin blinked and thought, "to turn a corpse into the source of carbon compounds, it's very simple to burn it at high temperature. As for other methods, such as being irradiated by a laser gun, and then the legendary destruction light, it also has the same effect!"

"You mean, there are such individual weapons on earth?"

Lu Ziming knows that the laser gun in Chiyou space can instantly turn people into ashes, but the volume of the laser gun is too large to be used in the laboratory room, unless the volume of this weapon is very small.

"Theoretically, it does exist, but Chiyou space does not have the same technology, nor can it make such a single soldier weapon!" Zixin shook her head.

"That means there are still some!"

"Yes! Chiyou space is not the most powerful existence. There are many people and things stronger than Chiyou space. It's good that Chiyou space can rank in the top 50 on earth." Zixin didn't feel embarrassed at all.

Compared with the calmness of Lu Ziming and Zixin, cold beauty and Rehmannia heard that there was a stronger existence on the earth, and their face became extremely ugly. "There was a stronger existence than Chiyou space. What kind of existence is that?"

Zixin's face became colorful: "The universe is so big that you can't imagine it. We are all frogs in the well of the earth. The real strength is the existence you can't imagine, but you don't have to worry for the time being, because you won't encounter it. Those powerful beings won't notice us, just like we won't notice the mole ants under our feet. We won't start until you are strong enough How wonderful the world is! "
