As soon as Lei Kun entered this base, he couldn't wait to find Tang Yu, but there were five people behind him.

"These five people can't stay." Thinking of this, Lei Kun stopped and turned his head to look at the five mercenaries.

These five people have all seen Lei Kun's true appearance, and Lei Kun is not sure that these five people have not discovered his abnormality.

He can now be said to be in the enemy's position, and once his identity is revealed, he will be able to die.

When the five mercenaries saw Lei Kun turn to look at them, they also immediately stopped and looked at Lei Kun with a nervous expression.

This organization is highly hierarchical, and it is precisely because of this that the mercenaries seem to be afraid of Lei Kun.

Lei Kun didn't know the secret of this, he just wanted to make these five people completely shut up now, so as not to affect his actions.

However, he can't act rashly, if he doesn't get rid of the mercenaries at the same time, it might cause other people.

Therefore, if Lei Kun does not make a move, once he makes a move, he will definitely cut the grass and eradicate the roots.

Just as the murderous aura in his eyes flashed, one of the mercenaries said, "Captain, you are ......"

The murderous aura in Lei Kun's eyes quickly hidden, and he said coldly: "It's okay, you guys take this mutant away first." ”

Before the mercenaries could react, Lei Kun had already left the corpse of the mutant behind, and then turned around and left first.

The reason why he didn't make a move on the mercenary was because he heard a slight footstep, which was getting closer and closer to where he was.

Once he made a move, even if he could kill the mercenary without alerting anyone, he didn't have time to clean up the scene at all, and once he was discovered, the result would be the same.

So Lei Kun chose to leave at this time, which was the wisest thing for him at the moment.

Just as Lei Kun left, a group of mercenaries came out on the other side, who were obviously patrolling here.

Several of them looked at each other, then walked in opposite directions.

At this time, Lei Kun walked alone in this somewhat empty passage, and the light above his head gave him the feeling of walking into a space-time tunnel.

Moreover, this passage is very long, and Lei Kun has walked for more than fifty meters without reaching the end.

When Lei Kun walked nearly a hundred meters, he stopped, because an elevator had blocked his way in front of him.

Lei Kun hesitated for a while, and finally gave up taking the elevator, after all, he had to be cautious at this time.

If you take the elevator at this time, the monitor in the elevator is enough to identify his appearance, and then he will be completely exposed.

Lei Kun returned the same way, and returned to the direction he left just now, there were four forks in the road here, one of which was the passage to the outside, and the other direction was the direction he had just walked.

Now there are only two paths left, Lei Kun pondered for a few seconds, and finally chose the passage on the left.

At this time, Lei Kun's appearance looked extremely relaxed, but only he knew that a layer of cold sweat had surfaced in his palm.

When he had traveled more than fifty meters, he suddenly saw a passage leading to the underground.

The appearance of this passage made Lei Kun happy.

He didn't know where the passage leads, but it gives him a choice.

Lei Kun soon came to the second basement floor, which was still as bright as day, and wider than the previous floor.

At this moment, a group of mercenaries walked towards Lei Kun.

After Lei Kun saw it, he was slightly stunned, but he quickly came back to his senses, he took a long breath, stabilized his breath, and walked towards the mercenary very calmly.

The distance between the two of them is getting closer.

The mercenaries were a little surprised when they saw Lei Kun, so they began to stare at Lei Kun.

Lei Kun naturally felt this gaze, and at first he wanted to leave as if he didn't care.

But when he thought about it, he also raised his head to meet the gaze of these people.

Neither of them stopped, but their eyes never moved.

At this moment, the two of them finally passed by.

Lei Kun naturally didn't stop, and soon missed the mercenaries, but he still didn't dare to relax.

As the distance between them became farther and farther away, Lei Kun breathed a sigh of relief, and then dodged and quickly hid.

The space in this base is too big, it is simply beyond Lei Kun's imagination.

As time passed, it was already dark at this time, but this was not the best time to act, so Lei Kun planned to hide first and wait until late at night, when everyone felt tired.

Lei Kun found a room with miscellaneous items, and he hid in a corner, covering his figure with a lot of things.

When he was sure that there was no danger, Lei Kun also slowly closed his eyes, he had to maintain sufficient physical strength to deal with the variables that existed next.

I don't know how long it was, it seemed to be four or five hours, maybe even longer, Lei Kun finally opened his eyes at this moment.

Lei Kun rushed to the door in a few arrows, he cautiously glanced outside, and only when he was sure that no one showed up, he jumped out.

After nearly an hour of searching, Lei Kun had already searched this layer.

Except for the occasional patrol mercenary, there was no one else.

"Not here? Could it be that it was transferred? Lei Kun muttered to himself, and there was a look of confusion in his eyes.

It's just that he won't give up easily, so he continues to lurk downward.

Just when he reached the third floor, he found that it was not as quiet as before, and there were many busy figures.

These people, dressed in white coats, are constantly shuttling through the space.

The most important thing is that there are many glass containers around these people, and inside these containers are one living person after another.

It's just that these people have closed their eyes at this time, and they look like they are asleep, if it weren't for them shaking their bodies from time to time, Lei Kun would have thought they were dead.

The most important thing is that these people have become unrecognizable, and some people are even like wild beasts, and they can't see what they used to be.

Lei Kun was secretly surprised when he saw it, because he could be sure that this was the place where mutants were cultivated.

When he saw these glass containers, his heart immediately lifted, he was afraid of seeing Tang Yu here.

Lei Kun walked past the glass container, and he carefully observed everyone inside.

After more than ten minutes, Lei Kun finally breathed a sigh of relief, because Tang Yu was not here.

At that moment, he suddenly heard a roar that felt very familiar to him.

Because there is also a hint of ferocity and helplessness in this voice, just like the mutant that Roral is fighting against.

It's just that the memories of these mutants seem to have been erased, and only the most primitive instincts of human beings remain.

Lei Kun looked in the direction of the roar, and just as he was moving his steps, he didn't expect that there was someone blocking his way.

Behind the mercenary was a door, and the sound of shouting came from behind the door.

However, there were six security guards standing in front of the door.

With such a heavily guarded guard, it was really the first time Lei Kun had seen it when he entered this base.

It was precisely because of this that his heart suddenly lifted.
