When Qiao Yu and Jiang Zhan came out the next morning, Cheng Sinian, Luo Zhenzhen and Yu Qingchuan were already neatly dressed and sitting in the reception area waiting for them.

Qiao Yu saw them looking like "Come to the meeting", so she pulled Jiang Zhan over and sat down, blinking in confusion, "What? Is something wrong?"

Cheng Sinian sat on the carpet with Luo Zhenzhen in his arms, his chin resting on Luo Zhenzhen's head. When he saw the two coming over, he first touched the strawberry mark on Qiao Yu's collarbone that was mostly covered by the collar but still vaguely visible. He glanced at it, and then while secretly praising his foresight in his heart, he said lazily: "The teacher said that we can't stay here at the foot of the mountain for too long and need to return to the cave as soon as possible."

"Go back?" Qiao Yu frowned, "I finally escaped, why should I go back?"

"Because of that stone." Cheng Sinian sighed, "The teacher said that we have to find a way to deal with that stone as soon as possible, otherwise it will be impossible to leave Mingxia Mountain, and we may not even be able to leave Zhongfeng."

Qiao Yu raised her eyebrows, "What do you mean?"

Yu Qingchuan continued: "According to Professor Kang, that crystal seems to be able to attract alien species. And the reason why they have been trapped here for so long is because this crystal cannot leave the middle peak of Mingxia Mountain."

Qiao Yu frowned again, "Attract alien species? What kind of attraction method is it? Will the alien species keep moving with the change of the crystal's position, or will it be like positioning, attracting the alien species to come in waves?"

"I'm afraid... both." Yu Qingchuan pursed his lips and continued to answer: "That small piece of crystal was forcibly peeled off by Professor Kang's research team from a large crystal in the alien nest. Originally, after they obtained the sample They wanted to return immediately, but they discovered that once the crystal left the range of Zhongfeng, alien species would come from all directions to round them up."

"And not only can't you leave Zhongfeng, but you also have to get as close as possible to the original crystal with that crystal. Once you leave the large crystal for more than two days, even if the crystal is still within Zhongfeng, , there will also be alien species coming here."

Qiao Yu suddenly realized, "Is that why Professor Kang and the others have been hiding in that cave?"

"Yes." Yu Qingchuan nodded.

"Then how did they escape the tracking of the alien species?"

"Take medicine." It was Cheng Sinian who answered this time.

Qiao Yu said nothing, raised her eyebrows, and motioned for him to continue.

"We all know that when alien species sense humans, they rely on the smell and sound emitted by humans. But few people know that they also use the same method when sensing mutated plants. This is how they sense mutated plants and animals. There will be no alien reasons for a strong territory.”

"Based on this characteristic, the institute has conducted a lot of research and found that whether it is humans or mutant animals and plants, the smells that alien species can perceive are two smells coming from the deep layers of the blood and the surface layer of the skin."

"In other words, as long as the smell of blood and skin can be changed, the smell can be masked to a certain extent, thereby avoiding the tracking of alien species."

"And it just so happens that there is a mutant plant that has such an ability."

"This plant can make the smell in its juice and skin very close to the rancid smell of the alien species, making the alien species and mutated animals mistake it for the same kind, and then lurk and secretly devour the target prey to strengthen itself."

"The institute has collected a lot of these plants, and then followed the principle of treating blood and skin together, and developed two medicines some time ago. One is an injectable medicine, and the other is a powder for external use."

"Inject the medicine into the blood, and then apply the medicine powder on the body with water. You can deceive heterogeneous and mutated animals to a certain extent and achieve the effect of 'invisibility'."

"Teacher and the others used this kind of medicine when they came here this time."

Yu Qingchuan also nodded beside him, "This medicine is indeed recorded in the research institute, I have seen it."

"Both of these medicines can only be used by aliens. After ordinary survivors use them, they will quickly have an alienation reaction and eventually become aliens. It is no different from being infected with a virus."

"The drug has a long-lasting effect. One injection can last about 20 days, but the powder can only last up to five days, so it needs to be reapplied every few days."

Fortunately, there are no requirements on the water quality for mixing the medicinal powder, and water sources that have been polluted after the apocalypse can still be used.

"However, this potion is only useful when the alien species is in a calm mood. According to the experimental results, when the alien species is in a violent or angry state, its perception ability will increase to five times its original value. In this case, the medicine will have almost no effect. of."

Cheng Sinian nodded, "This is why the teacher's team has never been able to get out of the middle peak. Because once the alien species senses that the crystal is leaving, it will enter a violent state. So the top priority is to return to the cave with the crystal as soon as possible. Then let’s figure out a way together to see how to take the crystal stone out.”

Qiao Yu touched his chin. If this was the case, it would be much more troublesome than imagined.

Qiao Yu looked at Jiang Zhan, "Azhan, what do you think?"

Jiang Zhan touched Qiao Yu's long hair, "Those alien species can indeed sense that crystal stone, and my mental power cannot block that stone. But if you want to leave, it is not impossible at all."

When the four of them heard this, they all looked at Jiang Zhan with wide eyes, as if asking: Do you have any idea?

When he left the cave yesterday, he noticed obvious changes in the group of alien species.He was sure that the alien species sensed the movement of the crystals at that time, so they wanted to attack them.Obviously, his mental barrier has no effect on that crystal.

But he is also certain that although his spiritual barrier cannot block the energy of the crystal, it can indeed block the alien species' perception of them.And he soon discovered that the perception of the crystals by those alien species should only be within a certain range.

Because after they quickly left the cave for a certain distance, the group of alien species stopped responding.

As for what Professor Kang said about "the alien species discovered that the crystal stone left and followed it," Jiang Zhan guessed that in the process of leaving, the crystal stone entered the range of the alien species sensing at the foot of the mountain or other places, and then attracted a large number of The alien round-up.

That is to say...

"Theoretically, as long as we leave quickly enough and keep a certain distance from the alien group, we will be able to get rid of them." Jiang Zhan looked at Qiao Yu's surprised expression and curled his lips slightly.

Qiao Yu's eyes widened even more when he heard this, "You mean...just like the alien species' perception of human beings has a limited range, do they also have a limited range of perception of that crystal?"

"Yes." Jiang Zhan scratched Qiao Yu's little nose, "But the problem now is that there are a lot of alien species here. Almost everywhere you go, alien species will enter the range of the induction crystal."

"So we need to find a path that doesn't leave us vulnerable from both sides."
