- "Hint, found ∑ energy crystallization signal, 153 centimeters away. ”

An inconspicuous hint, if it hadn't appeared on the retina of Zhou Yan's eyeball, he might have ignored the past directly. Not anymore, when he saw the symbol "∑", his whole body was excited.

It really feels like you've got what you want.

When he was in the car, he was still thinking about when he would find ∑ energy crystal, and now ∑ energy crystal appeared next to him. I walked around the room before, and there was no hint, but the team member stirred the skull, and suddenly came a hint, obviously, there was something wrong with the skull.

Zhou Yan immediately leaned down and picked up the skull.

"Zhou Ban, what are you picking up that thing for?" The team member saw Zhou Yan's movements and asked casually.

"Take it back and study it and see if you find anything...... Li Ban, it's better to take this skeleton with you, since the mutant baby has a problem, it is difficult to say that its mother has no problem. ”

After listening to Zhou Yan's words, Li Yao thought for a moment and said, "Okay, bring the bones with you." ”

Taking advantage of this opportunity, Zhou Yan quickly observed the skull, and the retinal light screen of the left eyeball had changed the content of the prompt.

- "Hint, found ∑ energy crystallization at a distance of 0 centimeters. ”

"That's right, it's this skull, and the energy crystals are in it!" Zhou Yan looked at the skull carefully, and the hair on the skull had fallen to the ground, and it had nothing to do with the ∑ energy crystal.

The skull was not white, but rather a little muddy, gray and black, and looked dirty. Fortunately, he was wearing gloves, otherwise he would not dare to pick it up, and he would feel nauseous in his heart.

On the surface, I couldn't tell where the skull was, as if it had crystallized ∑ energy.

"Squad Leader Zhou, are you so interested in skulls?" An evolutionary picked up the bones while turning his head to look at Zhou Yan, who was holding the skull and pondering.

Zhou Yan knew that he had to find an excuse and kept the skull in his hand: "Observe and observe, zombies can grow a brain nucleus in their brains, and I don't know if there is anything similar in this skull." ”

"Aren't you afraid? When I saw the bones, I felt a little sad in my heart. ”

"As a police officer, I have a lot of work with corpses, and I used to go to the criminal police team to observe the opening of the three chambers, and I also had forensic anatomy, and the bones of the dead were not touched."

Zhou Yan exaggerated the facts, although he has seen autopsies, it is rare, no one likes to go to the criminal police team to see the corpse if there is nothing to do, let alone touch the organs and bones of the dead with his own hands.

There is this taboo.

After a while, the bones had been converged, but Zhou Yan still didn't find the abnormality of the skull, and he didn't find any trace of the existence of ∑ energy crystals.

"It feels like this bone is not the same as a normal bone, I'm studying it on the way, no problem, right?" Zhou Yan found an excuse that was not very reasonable.

Li Yao thought about it and felt strange, but did not refuse.

Smooth descent from the stairs.

"This bag is the corpse of the mutant baby, this bag is the bones of its mother, and the two bags of things will be handed over to you in one car, Zhao Hai, be sure to send the things back to the camp safely."

Zhao Hai nodded: "Don't worry, squad leader, if you can't beat the insects, you will hide, and there will be no more problems." ”

"Okay, then let's disperse here, one car will go back, and the second car will continue to drive east to collect mutant plants."

"Be careful."

"Roger, go!"

……

Li Yao led people to collect mutant plants.

Zhou Yan followed the car back, he sat in the passenger seat with the skull, and after finding an excuse to dispel the abnormal eyes of Zhao Hai and others, he continued to ponder the matter of the skull.

After repeated observations, he finally found out what was different about the skull, the inner wall of the skull, there was a layer of fine sand-like particles.

With a little fingernail buckle, you can buckle off a lot of grains.

Looking at the black-brown sand grains in his palm, Zhou Yan thought slightly: "This thing looks like sand, and if you look closely, you can see a slight sense of transparency, could it be that it is the crystallization of energy...... But how do I prove it's an energy crystal, by the way, I can put the skull farther away. ”

He placed the skull on the frame of the car, keeping the skull twenty centimeters away from himself.

Sure enough.

The prompt of the retina light screen has not changed, and it is still displayed as 0 cm away from the ∑ energy crystal. When he put the sand in the palm of his hand into his back bone, the distance quickly became 24 centimeters.

"This is the crystallization of energy!"

Zhou Yan used his fingernails to scrape the ∑ energy crystals on the inner wall of the skull and put them in the palm of his hand to gather into a small pile. In his heart, he was wondering how to absorb these ∑ energy crystals.

∑ energy crystallization, which can be used to produce nanorobot swarms.

"Do you want me to eat these energy crystals directly, just like I eat radiation nuclei?" He felt a little sick, after all, something scraped from the top of a dead man's skull.

But radiation nuclei can be eaten, and it doesn't matter if you eat ∑ energy crystals or not.

"Go back and wash it before eating."

Once you've made your decision, put away this little ∑ energy crystal.

He leaned back in his chair and began to ponder for a ∑ of energy crystals that appeared in his skull, causing him many associations.

First, did the ∑ energy crystals gather after the mother's death, or did they gather before her death? If it is alive, does it mean that it can gather in the human brain; If it is after death, what attracts ∑ energy crystals that accumulate inside the skull?

Second, what is the relationship between ∑ energy crystals and mutant babies? Could it be that the ∑ energy crystallization caused the mutation of normal babies, or is it caused by multiple factors such as ∑ energy crystals, Ω evolution fluid, and theta radiation gas?

Third, the Ω evolutionary fluid was found in the bodies of mutated plants and xenomorph giant insects; Theta radiation gas can be free in the air, can also be absorbed by xenomorph giant insects, and can also form radiation nuclei in the zombie brain; ∑ energy crystals have also been found inside human skulls. Does this mean that Ψ Variant Ore may also be found in humans, animals and plants?

The first two points need to be further demonstrated.

But on the third point, Zhou Yan quickly denied himself.

Ω evolutionary fluid and theta radiation gas are measured in grams; ∑ energy crystallization is measured in kilograms. And Ψ Hundred Variety Ore uses tons as a unit.

What a huge amount of animals and plants must be to form a Ψ variety ore in tons in the body...... If it is only in trace amounts, then how many animals and plants must be slaughtered and how many things must be eaten in order to absorb enough Ψ Variety Ore...... In addition, Ψ Variety Mine is a kind of mine.

The mine is probably similar to gold and silver mines.

"Maybe there is a Ψ Variety Mine in the Black Magnetic World?"

Thinking all the way, all the way smooth.

No more bugs, zombies, or other monsters were encountered, and they returned safely to the Emerald Lake camp. The experts and professors of the scientific research class immediately took the bones of the mutant baby and the mother over and immediately began to do research.

Zhou Yan changed into clean clothes and prepared to go to the management committee. From the list of the management committee, 20 team members were selected as permanent members of the security team, and then more than 3,800 people in the camp were organized into more than 100 formations, and the time for each team to serve as mobile team members was arranged as a whole.

But before he went, he found a loophole, washed the little ∑ energy crystal, revealing the true color of the yellow-brown sand grains, and then ate it in one bite.

A few seconds later.

The prompt appears.

- "Hint, it was found that ∑ energy crystals entered the body, the number is scarce, and it has been collected, but it is less than 1 kilogram, and it cannot support the application. ”

Seeing this prompt, Zhou Yan was not surprised, but was very disappointed.

∑ energy crystallization requires one kilogram to be applied, one kilogram is two catties, if it can only be scraped from the skull, how many skulls do you have to scrape to scrape two catties...... Besides, there are so many skulls that form ∑ energy crystals.

"We have to find new ways to get ∑ energy crystals."
