Those who have not yet reached level 5 will soon lose the qualification to survive in the world of Thriller if they do not reach level 5 as soon as possible with the help of their own efforts and the help of other players.

Fortunately, Liu Qian has always kept his level ahead of this evolutionary speed, so that he can live a fairly nourishing life in the trembling world.

But it can also be seen from this that players can't relax at any time, once they slack off and let their evolution speed be lower than that of zombies and monsters, it will become extremely difficult to survive in this trembling world, and they will even be eliminated soon.

Liu Qian and Nana rushed forward and easily seriously injured these dark spot zombies, and after the team members harvested experience points, another player consciously followed Nana to the depths of the corridor, and after confirming that it was safe, everyone followed.

At the end of the corridor is a stairwell, with an elevator on one side and a fire staircase on the other, and now that the power has been cut off in the laboratory, it is obvious that the elevator cannot be used, so everyone can only choose to take the stairs.

Going down the stairs, although they have already descended one floor, there is no door to lead to the floor, so everyone can only continue to go down. Everyone walked down the fifth or sixth floor, during which they encountered some black-spotted zombies hunting experience points, and at the same time, they also saw the corpses of some zombies leaning against the wall that had rotted, which seemed to be the traces left by Qiu Zitao and Zhao Nanshan, who had fought here before.

After descending seven flights of stairs, there was finally a door leading to the floor, and a member of the team followed Nana to open the door first and explore, and after confirming that it was safe, everyone followed in.

Inside is a long, narrow passageway. At the end of the passage is a large hall. In the center of the hall are several sofas and a coffee table. There are also several rooms along the walls. After arriving here, everyone finally understood what happened here the last time Qiu Zitao brought someone over...... Because, the ground was full of corpses, and the bodies of the dozen or so players who came with him all fell to the ground in all directions.

Some of the corpses had their heads no longer on their necks, and some had several large cuts cut out of their heads, and they were completely dead at that time. Not even zombies have become. Their corpses emitted a very strong rancid smell, and if it weren't for the fact that the players' bodies had been strengthened several times and their resistance was super strong, they would have been unable to resist this rancid smell.

After examining these wounds, Liu Qian couldn't help frowning, because he found that these wounds were all caused by the big axe, the same big axe he had taken from Qiu Zitao, which seemed to mean that these players all died at the hands of Qiu Zitao.

I just don't understand why Qiu Zitao wants to kill these players here, could it be that he found some treasure, and then everyone fought for it. Qiu Zitao killed everyone else and fled back alone? However, I feel that with the strength of other players, it is impossible to be stupid enough to compete with Qiu Zitao. Unless something goes wrong with their brains, they're killing themselves.

So...... Why did Qiu Zitao kill the players who came in with him?

In addition to Liu Qian, the other players seemed to be aware of the problem after examining the wounds on the corpses at the scene. The expressions on everyone's faces looked a little weird, as if they couldn't figure out why the original leading brother wanted to kill these younger brothers around him, you must know that these people who followed Qiu Zitao were all the descendants around him at the beginning.

That's when 'Bang! A muffled sound came from behind everyone, and everyone hurriedly turned around and looked behind, and a heavy metal door fell from the passage behind them, completely sealing the passage that everyone had just entered! At the same time, the lights came on in the underground space where everyone was staying.

The lights are bright enough that the lighting in the player's hands doesn't make much sense and can be turned off.

"What's going on?" The sudden change made all the players seem a little panicked.

Zhao Nanshan is right, this is indeed a trap. When Liu Qian first came over, he expected that such a thing might happen, but since the maps in Du Sheng and Zhao Nanshan's hands marked this laboratory, it means that this laboratory is indeed very valuable for exploration, so even if he knows that it is a trap, he has to step in.

Since Qiu Zitao was able to escape from this trap, Liu Qian believed that with his wisdom and ability, the worst result would be nothing more than nothing to gain and escape from here, so there would be no loss for him.

"Hello, welcome to the Psychoanalytic Research Center of the Three Domains Company." A voice suddenly came from the top of the space.

"Who are you?" Liu Qian raised his head and asked in the air.

"I'm the mastermind of this lab, and I'll only be activated when intelligent beings here, such as humans, enter." The voice replied to Liu Qian.

"What do you want to do?" Liu Qian asked the mastermind again, and at the same time, the robot dog Nana and Jiang Jinyuan began to search and scan around, trying to find something similar to a terminal to see if it could invade it.

"You must have come here to find some benefits from here, right? I have a lot of research on the human psyche, so I know your intentions very well. I'll be honest with you, I do have some great treasures here. The mastermind seemed to laugh as he spoke.

"Now that you know our intentions, let's be honest and hand over all the treasures you have hidden! Otherwise, let me beat you until you hand over these treasures. Liu Qian took out a big axe and threatened the mastermind.

"It's okay to hand it over, but you have to pass my three tests." The mastermind didn't seem to care much about Liu Gan's threat.

"What test?" Liu Qian continued to chat with the mastermind, giving Jiang Jinyuan and Nana more opportunities to find possible electronic terminals.

"Wisdom, courage and killing, there are three tests, the first test has begun, and among all of you present, only the last one alive will pass the first test, passing through the metal door in front and entering the next test area. At the end of the half-hour countdown, if there are more than two people alive, I'll activate an air blast to completely clear the room. The mastermind replied to Liu Qian.

"What do you say? Why should I believe you? What proof do you have that you can dominate everything here? Liu Qian waved the big axe in his hand and asked the mastermind sharply. (To be continued.) )
