Li Sa took the time to start with the teachers who had been to the extremely cold place, trying to see if they had encountered the current situation when they came twenty years ago, and it was obviously the first time they had encountered zombies, and no one knew about the concept of parasitic demons.

I swept around and found nothing. Anyone who has been there twenty years ago seems to have memory loss. They only remember that they did not encounter demons after entering, and they went all the way smoothly and attacked the nearest demon fortress. In this way, they cleaned up the demons in the fortress one by one and slaughtered them cleanly.

Those demon adults who succumbed to the demons and attached themselves to the fortress around them, they did not show mercy, they all killed them together, and only rescued some ignorant children.

Li Sa found that in their memories, all the experiences seemed to be the same, just like the perspective "recorded" by the same person, copied into the minds of these people, and there was no problem with applying it to anyone. This suggests that the truth may well be so shocking that it must be covered up, not even just to erase the memory, but to implant a uniform edited memory.

Ling Shang did not have this similar content, perhaps because he played the role of gatekeeper. All those who went deep into the extreme cold and left alive were uniformly tampered with their memories.

What about Ling Yu? It is impossible for the brainwave energy to be so high that it was generated all at once, maybe he was different from ordinary people when he was a child, or he may remember something, but it was just sealed and not completely washed away.

Li Sa approached Ling Yu and asked softly, "What do you remember?" ”

Within the formation formed by the self-study lamp, the conversation between the several of them would not be overheard by outsiders. The crowd didn't pay attention to what this team of people with no combat power was muttering.

Ling Yu said, "I can't think of anything. When we were brought out, we must have been in a coma for a long time, and I don't know what the Xiuzhen elites did during that time. I only remember that at the beginning, there were a lot of cultivators' team, and later, there were less than fifty people left the barrier wall. ”

"Are there any of those zombies that you knew twenty years ago?" Li Sa's sentence was just a casual question, after all, it was a brain-opening idea, even if there were, after twenty years of zombieization without people or ghosts, people's appearance would have been difficult to identify.

Unexpectedly, Ling Yu replied: "I just saw a person from my parents' clan. The child was the same age as me, born with three arms, and the demon liked the strange-looking child, so he brought him into the demon fortress in advance. If he hadn't died twenty years ago, he would have been an adult by now. There happens to be an adult with three hands among the zombies. ”

"Is that person still there?" Li Sa wanted to lock that person's memory and check it again.

Ling Yu smiled bitterly, "I've been attacked by magic and rotted into mud. ”

Lu Jingjing asked, "So they must not be normal demons, right?" ”

Ling Yu nodded: "Although our tribe is poor, poorly clothed, and not well fed, people are still normal, they will cry and laugh, and they will not attack others inexplicably. To put it bluntly, my impression of the people is no different from the outside world. They were simply trapped within the walls of the barrier, forced to become slaves to the demons. ”

"So you never thought about leaving?"

"How to leave? Demons can't leave, and cultivators who only come once in twenty years kill demon adults indiscriminately...... Everyone is afraid that even if they go out of the barrier, they will still die, and at least they can live within the barrier. ”

"Didn't they take the children? It is said in the scriptures that no one who is willing to surrender will be killed. ”

"We don't speak the language, who has the final say on whether we are willing to surrender or not? They only take away the young children who are easy to move, and they don't take all of them, they should pick a small number according to some criteria, and leave the rest in the ice and snow to their own devices.

The older children are all inside the demon's fortress. How many can they take with them when they come in the hundreds? There are thousands of demon fortresses in the extremely cold land, and there are more than 100,000 so-called demon clans living together. How many people will be able to follow them away? Twenty years ago, no one knows the details, and who can say what happened to those demon sealing trips that were not recorded before? When Ling Yu said this, he was depressed.

Li Sa rarely felt his mood swings and asked him, "So do you hate people outside, or demons, or some other existence?" ”

Because Li Sa noticed that Ling Yu didn't have much emotion when he talked about the clansmen, he also used "they" to distinguish them. What did he subconsciously think of himself? Different from the demons here, different from the cultivators outside?

Ling Yu paused for a few seconds, and replied seemingly reasonably: "Other children seem to be doing well, maybe I am the only one who has met Ling Shang." ”

After saying this, his emotions converged again and changed back to his low-key appearance.

The results of the teachers' meeting had already been obtained, and Teacher Mei and another teacher found Li Sa together and asked, "Classmate Li Sa, can you control your spirit beast to fly to a high place to explore the way?" ”

Teacher Mei also added: "If you don't have enough spiritual power, you can bring other students with you. ”

Li Sa said, "Well, I can go to explore the way, but how can I send a message to contact you?" ”

Teacher Mei took out three communication paper cranes and taught them how to use them. This really doesn't need aura, and if you read the mantra correctly, you can record and convey the message.

Of course, Li Sa, the prop given by others for free, did not shirk, accepted the paper crane, called Zhao Yin and Lu Jingjing, and asked Ling Yu again: "Are you going to explore the road with us?" ”

These few of them didn't have any offensive power, and letting them out to explore the path would not affect the current defensive array organization, it didn't matter if there was one more or less, Teacher Mei, they didn't pay attention to it, and turned around to arrange other things.

Ling Yu didn't hesitate and got on Li Sa's big bird.

Li Sa led people to take off into the air, and the classmates below were envious, but more people still concentrated on cleaning up those zombies. After all, it is impossible for zombies to increase indefinitely, so if you seize the time to kill more, you will be able to reduce them in the future.

After Xiaohua took off, Ling Yu said, "Teacher Mei and Yao Qinshan are not quite right, they are shrouded in black qi, and they are getting heavier and heavier. ”

Lu Jingjing worried: "Are they possessed by demons?" ”

Li Sa asked: "Is there something else in their bodies, not the kind of demons, like small snakes or others, attached to their bodies?" ”

The fact that the three of them couldn't see it didn't mean that Ling Yu couldn't see it.

In fact, Zhao Yin had already noticed the changes in the energy field, but he couldn't confirm whether he was parasitic or not. If they are parasitized, are those people parasitic? They still seem to have the normal sanity of human beings, and they are faithful in their duties. Before there was any abnormality, he was suddenly killed, what would others think?

Li Sa didn't want that to happen, if the parasitic demons were parasitic on the cultivators, would the task they complete in one day be for them to kill all these cultivators who came in? Even if they can do it, they can't bear to do it, but the scale of nearly a thousand people is not really the number of a thousand, where can the rest of the parasites who are not enough come to make up the number?

It's not scientific!

Hopefully, those black energies aren't parasites, but something else. Bah! Nothing else, anything more terrible.

Xiaohua flew for a while, and finally saw a large open space without zombies. Lu Jingjing released the first communication paper crane and informed everyone of the direction of movement, which is good news, at least zombies are not endless.

Li Sa asked, "Is the aura here stronger than other places?" ”

Ling Yu said: "There is no difference between here and there just now, it is still the appearance of depleted spiritual energy. It's so weird, let's go a little deeper, okay? ”
