The leading teachers of each school each took out a magic weapon and selected the location to open the seal according to the coordinates provided by the Cultivation Committee. Now to create a very complex large formation, it requires the cooperation of multiple teachers, and it took two hours to complete, and then the spell was recited to open the seal.

The opening time of this passage is time-limited, as a temporary entrance, it can be quickly and urgently closed through magic weapon control, even if it is not artificially closed in time, it can also be preset in advance to automatically close the time, so as to prevent the cultivators from being wiped out and no one "closes the door" and causes the demons in the enchantment to run out.

Although this has not happened in thousands of years, the formation was originally designed with the possibility of such a scenario.

Li Sa saw a golden crack appear on the endless frozen wall, and the gap became wider and wider, as if a crack had been torn from the inside, until it was as wide as ten people passing side by side, and the height was the same as the width, and then it stopped expanding. The formation under the feet of the teachers also creates a huge transition space.

This reminds Li Sa of a certain bridge design for entering and exiting the plane. There is a transition space between the two spaces to accommodate the setup of multiple gates. After stepping into the formation, the person may have left the ice field and entered some kind of controllable alternate time and space.

Li Sa couldn't see anything on the side of the aperture at this time, and it seemed to be pitch black behind the golden light, but when she stepped into the formation of the transition space and looked at the other side of the aperture again, the brainwave controller suddenly began to mark wildly.

Li Sa secretly gasped, at the end of the passage, there were so many high-level intelligent lifeforms in the enchantment that could be marked with brainwave energy? They can't all be demons with abilities, right?

Fortunately, although there are many brainwave energies that can be marked, the levels are between 9 and 10, and no higher-level ones have been found for the time being. No matter how bad it is, it is a creature similar to the thousand-legged centipede that came out of the cracks in the previous world, and it can be done with small flowers. So Li Sa was ready to regulate the emotions of those creatures at any time, at least for a second or two to keep the creatures over there in a daze, and then he could buy time for the cultivators here to make moves.

The team leader of the school who bore the brunt of the battle was also the one who had entered the enchantment back then, and he was the one with the highest cultivation among all the team teachers, and he also sensed the anomaly on the other side of the enchantment, and pinched the trick to sacrifice the defensive array.

Then the people who walked into the barrier saw the scene outside the defensive array.

There is indeed a white snowfield, just like the outside of the wall, but the black pressure on the snowfield is full of people. It's not accurate to say that they are human, but they can only be said to be humanoid creatures.

They have clothes that look like rags and skins, or they may actually be their own skin. Their heads and faces were as gray as those of dead men, and their movements were stiff and slow, as if they had frozen after walking in a cold place for many days.

They seem to be able to sense something warm approaching, and they will huddle around the exit of the passage that suddenly appears. But there were obviously some protections there too, and they didn't dare to get too close.

They were like dead people walking upright, silent as ghosts, and many of them had no eyeballs in the hollow eyes of their corrupt heads, except for one hole. Most of their limbs are also incomplete.

When Li Sa and other players saw such a scene, their first reaction was that they encountered a group of zombies.

The audience in the 666 live broadcast room also exclaimed:

[Did I string the channel, what did you see?] ]

[You read that right, the ones around the anchor should be zombies, right?] ]

[Think about it with the setting of Xiuzhen, are these innocent people possessed by demons?] ]

[The demons in the enchantment look like this?] ]

[Look at Ling Yu looks like a human.] ]

[Can someone tell us about that?] ]

[Don't wait, the system will block the truth, I just tried, let's think differently first.] ]

[Those things look disgusting, don't they look like they don't have much attack power?] ]

[The attack power is definitely not as good as that of cultivators, but who knows if they have anything strange or a source of infection on them?] ]

[Does this have anything to do with the strange mutated creatures outside the walls?] ]

[The anchor is dangerous, there is no biochemical protective device and hurry up and put it on!] ]

There are actually zombies in this kind of cultivation world? Are these people demon-possessed, or are they infected by some kind of contaminant? And then Li Sa wondered if this place was full of contagious things? The barrage said that she was not prepared for the biochemical protective device, and in the previous life, she only dealt with the physical attack of the collapse.

Zhao Yin took out three gas masks from the space, put one on herself, and handed out two more to Li Sa and Lu Jingjing, and advised: "This thing doesn't look clean, and I don't know if the magic can prevent that, so let's prepare more." ”

After Li Sa's group of people entered the enchantment, the three of them received point rewards one after another, as well as a system notification: [The first step of the advanced series of hidden tasks has been completed, and the second step is to kill 1,000 parasitic demons in the extremely cold land, with a time limit of 1 day. 】

Here are a few notes:

1. Tasks can be completed by multiple people, but only for players who have already activated the hidden task, and the task cannot be directly shared with other players.

2. 1,000 points can be obtained for completing the second step, 10,000 points for the third step, and so on.

3. If the task is not completed within the time limit, the hidden task will be automatically terminated.

4. You can take the initiative to abandon the series of hidden tasks at any time, and the dangerous scenes and random events related to the tasks will no longer be triggered.

Li Sa deeply suspected that these zombies in front of him were the "dangerous scenes" that were suddenly brushed out because of the high-level hidden mission, and the parasitic demons mentioned in the mission were in the bodies of these zombies?

These things that don't look like living people should have been dead for a long time, and their brainwave energy is still close to that of living people, is there something parasitic in their bodies?

Li Sa stared and tried to comb through the fragments of their memories, only to find that they were still human memories. Most of them are ordinary people living within the walls of the barrier, or humans known as demons, who are enslaved by demons and serve them in exchange for food.

The extremely cold place within the seal was particularly cold, and from time to time there were strong winds and heavy snow, and the snow was so deep that it could reach the top of an adult's head. For half a year the sun never rises, and another half the sun never sets in the east.

The outdoor ground is frozen and cannot be cultivated, so people can only fish from the ice sea or eat the meat of some large beasts. Fire is precious, and sometimes a big snowstorm and the fire is gone. Only in the castle of demons, there is always fire and light, it is very warm, it does not feel cold without clothes, it is as bright as day, and green plants can grow.

People live near the demon's fortress and voluntarily sacrifice their children to the demon in exchange for food produced by the demon.

So their children have always been in the demon's castle, and it is said that at least they don't have to starve and freeze, and when they reach adulthood, the children will be released, when they are already strong and fully adapted to the cold weather, so that they can reproduce outside the castle.

However, in recent years, a lot has changed.

Memory fragments began to mess up.

Li Sa didn't have time to sort out more information, but based on past experience, he asked Lu Jingjing to remind everyone to give priority to attacking the heads of those zombies. When the head that sent the signal is damaged, the limbs of the zombies will also lose their mobility. If it doesn't work, it means that there is really a parasitic manipulation, or some other spell is manipulating them, then another means are needed. (End of chapter)
