Each troglodyte had a black mass of bodily fluids on its back, which constantly eroded the troglodyte's skin. They stretched out their black tentacles and kept approaching Lin Ye.

The troglodyte was divided into three groups from old to young, among which the old and frail troglodytes were divided into a group, and there were thirteen of them, and their normal bodies were covered by black body fluids.

The young and strong troglodyte dragons stood on the open ground, there were five of them, all of them were weak, and the rest of the land there were fifteen prime-aged troglodytes scattered around the underground cavern, looking for any food to eat.

The only remaining were ten troglodyte cubs, huddled in the shady corners of the cave, each so hungry that they couldn't even stand up.

Surrounded by new caves that cavemen have tried to dig, they have abandoned the passages they once dug, and they have abandoned the food and fat roots that have been stored for years.

Lin Ye opened his throat and sang a song, and the familiar melody immediately made the cave dragon recognize Lin Ye as the bird that befriended them. At the same time, they sniffed the food that Lin Ye had brought.

The alluring scent suddenly made the cave dragons go crazy. They are trapped in underground caves, and although there are underground lakes that can provide enough water to meet their drinking needs, food is not so easy to find.

A cave dragon lowered its head and chirped happily at Lin Ye, it shook its body and showed friendship to Lin Ye. At the same time, saliva was left on the side of the mouth. Although it has no eyes, it also "looks" directly at the food and grass basket behind Lin Ye.

"Warning, all troglodytes have been extremely mutated, and without the help of their hosts, they will be wiped out within a month. ”

"It's easy to do, I'll get rid of all the infections on them. Lin Ye said in his mind, now is the time when he needs help, it is impossible to sit idly by and ignore this group of dying cave dragons.

"No, although the host's purification flame can eradicate the mutant infection, there is still a possibility that the infection will recur in the troglodyte dragon. ”

"If the infection is eradicated, will the infection recur?" Lin Ye felt that the system was telling a joke, but decided to listen to the system's explanation.

"Taking cancer as an example, even if all cancerous tissues are removed and all cancer cells are killed, there are still many people who die because of cancer recurrence, not because cancer cells have survived, but because the environment of the surrounding ordinary cells has not changed, coupled with the patient's weak body and low immunity, these ordinary cells are like a time bomb, and there is still a great possibility of re-mutation into cancer cells. ”

"Therefore, there are two ways to completely eradicate the extreme aberrant infection. ”

"What's the solution?"

"The first way: kill all the troglodytes. The system said indifferently, the life and death of the cave dwelling dragon has nothing to do with it, it only cares about Lin Ye's life, and everything is considered for the host. "Of course, the host can also ignore it, and after all the troglodmites have undergone extreme mutations, the population will quickly die. Mutant infections also die out quickly after losing their main body. ”

Lin Ye nodded, understood the meaning of the system's words, and said in his heart: "That's the truth." And what about the other way?"

"The second way: it is to let the caveman evolve again, so as to repair the genetic defects in the body, and safely pass the first obstacle of the intelligent evolution belt. Extreme mutation originated from the caveman gene, and in order to completely eliminate extreme mutation, it is necessary to modify the gene. ”

"But for the host, there is a safer way for the troglodyte dragon to go, that is, let all of them join the host's totem shelter area and become residents of the Phoenix tribe, and the totem can effectively suppress the extreme mutation probability of intelligent creatures. Now, the host can ask them to join the sanctuary. ”

The reason is very simple, that is, the lives of the entire family of the cave dragon are now in the hands of Lin Ye's "hand".

This is a good opportunity to invite them to join him!, Lin Ye suddenly had an idea in his mind, and he walked slowly to the caveman.

Lin Ye picked up a fat steamed grasshopper and shook it in front of the cave dragon's nose, and the cave dragon's body suddenly shook violently, and a mouth was about to bite it. Lin Ye stretched out his wings to stop the caveman, and Lin Ye screamed a few times, telling the caveman that if he wanted to eat these foods, he had to join himself. And Lin Ye will also help them dispel the infection on their bodies.

Driven by hunger, the cavemen nodded in agreement. After soliciting the opinions of all the cave dragons, Lin Ye successfully implanted the power of faith in the mind of the cave dragon, and the images of dozens of cave dragons also appeared in Lin Ye's mind. Each of them is more than half a meter tall, and their forefeet are thick and strong, making them good diggers.

But while the troglodyte dragon was lining up to become a resident of the Phoenix Tribe, an elderly troglodyte refused to become a resident of the sanctuary area, and it came out of the queue and leaned against the edge of the cold, damp cave. It instinctively resisted the infusion of Lin Ye's power of faith, and seemed to have formed a unique value.

"If a moderately intelligent creature is discovered, if it survives the mutation crisis safely, this troglodyte dragon may lead the clan to establish the troglodyte dragon totem, and it will also become a believer in the totem. ”

The totem tribe is divided into three levels, which are the first-level tribe, the second-level tribe, and the third-level tribe.

Tier 1 tribes have totems, but no totemic spirits. This means that there are no higher sapient beings, as only higher sapient beings can become totem spirits (the exception is the lizard redback, which is a medium sapient creature, which is a totemic spirit inherited by blood. ）

The second-level tribe has totemic spirits, but there are no high-level intelligent beings in the tribe other than totemic spirits.

The members of the third-level tribe have all possessed advanced intelligence, and the entire tribe is sprinting like a higher civilization.

Once there are medium intelligent creatures in the tribe, it means that they have the premise of establishing a totem, and once a totem is established, it means that their community has become a first-class tribe. And the troglodyte dragons already have this premise, which is a pity that it will soon be destroyed.

Lin Ye remembered the black low-level eyeworms he had seen in the underground cave, and suddenly understood a little. Even if the caveworms did establish their own totems, the euglena associated with the troglodyte would become intermediate, and eventually the troglodysaurus group would fall under the extreme mutation caused by the intermediate euglena.

And this is the crisis that every community encounters.

There are eyeworms in the front, and there is the threat of extreme mutation in the back, without Lin Ye's help, the cave dragon group is doomed to a dead end regardless of whether it has established a totem or not.

Lin Ye watched the old caveman walk to the side with respectful eyes, and Lin Ye sighed in his heart.

This is a community that has the potential to establish totems, and their choice to join the forest night means that they will leave the opportunity to establish their own tribe to the totem spirits who shelter them. And according to common sense, how could a totemic spirit allow them to break away and create a new totem?

The old caveman chose to stick to his idea and did not join Lin Ye, even if death awaited it. Whether it is pedantic or stubborn, it is all for its own race, and Lin Ye chooses to respect it.

Lin Ye stood on a small stone in high spirits, and began to guide the flames on his body to expel the mutant infection from the cave dragons one by one. Although the old caveman did not join Lin Ye, Lin Ye also purified the infection on its body.

Lin Ye wanted it to witness the rise and fall of the cave dragons under his leadership in the future, so that it could once again consider whether to join him. Between the gestures of his wings, Lin Ye had faintly shown the demeanor of a king.
