As time passed, the people here did not calm down, but more people were involved, and at this time it seemed that the place was completely uncontrollable, and it completely turned into a melee.

And Lei Kun took advantage of this time to slowly withdraw from the scope of the battle and walked towards the passage.

Lei Kun stuck to the wall, took a quick look at the chaotic battle circle in the middle, secretly rejoiced, and then rushed into the passage with a few arrows while everyone was not paying attention.

Although Lei Kun also doubted why there was no obstruction in this passage at this time, he thought of the mercenaries guarding outside, so he temporarily dispelled his suspicions.

He quickly crossed the stone staircase, which was more than ten meters long, and came to this layer underground.

When he stopped, he found that it was very dim, and the light on the wall could only let him see the distance of dozens of meters in front of him, and if he was imprisoned here for a long time, he would definitely be driven crazy.

Thinking of this, Lei Kun immediately quickened his pace.

But it was precisely these tens of meters of distance that made Lei Kun see that there were more than a dozen iron gates on both sides of the long passage in front of him.

"Will Tang Yu be imprisoned here?" When Lei Kun thought of this, he hurriedly ran to the iron gate and searched them one by one.

Lei Kun looked inside through the gap in the iron door.

The person imprisoned in the first room was curled up in the corner, looking unkempt, and it was pitch black inside, and it was impossible to see the person's appearance clearly, and Lei Kun, who was standing at the door, only smelled a foul smell.

However, Lei Kun quickly determined that this person was not Tang Yu, because Tang Yu had not been imprisoned for a long time, and his hair would definitely not grow like this.

He looked quickly inside the second iron door.

The man here was skinny, and when he saw Lei Kun, he immediately rushed over, but he may have injured his leg and walked with a limp.

When this person approached, Lei Kun showed a hint of disappointment, because this person was not Tang Yu either.

But when this person saw the clothes on Lei Kun's body, he immediately screamed, quickly retreated, and shouted: "I can't do it anymore, I can't do it anymore, don't take me away, don't ...... it."

Lei Kun listened to this person's incessant chatter, and knew that this person should have also participated in the experiment, but this person has lived until now, and he doesn't know whether it is lucky or unlucky.

But Lei Kun didn't have much time to delay, and hurriedly looked towards the next iron gate, but unfortunately, it was not Tang Yu who was being detained here.

In the next three minutes, Lei Kun looked at the people behind the iron gate, all of them were crazy, but none of them were Tang Yu.

This also made Lei Kun secretly rejoice, if Tang Yu was really crazy, then he would regret himself for the rest of his life.

"Has he been transferred?" Lei Kun muttered in surprise, and then he set his eyes on the completely enclosed iron door at the end.

Lei Kun walked over slowly, put his ear to the iron door, and listened to the movement inside, but there was no sound inside.

He hesitated for only a second before drawing a dagger and picking open the combination lock next to the iron door.

Now Lei Kun's hands were also trembling slightly, after all, he didn't know if the person in this was Tang Yu or not.

If the person here was Tang Yu, then everyone would naturally be happy, but if it was not Tang Yu inside, but an extremely terrifying mutant, then Lei Kun would be too late to regret it.

But this was also his last chance, and he had no choice at all.

Lei Kun looked at the few copper wires behind the circuit board, and after looking at it for a full three minutes, some cold sweat had already broken out on his forehead, and he couldn't help but be a little nervous at this time.

But he hesitated for a moment, and finally picked off a copper wire.

But when Lei Kun picked off this thread, he found that there was no reaction.

Lei Kun was stunned for a few seconds, "Damn, no, why didn't you react at all, is this thing broken?" ”

Just as he finished speaking, there was a "click" from the iron door.

Although the voice was very soft, it fell on Lei Kun's ears as loud as spring thunder, and a smile instantly appeared on his face.

Lei Kun slowly walked to the iron gate, with a trace of apprehension and nervousness in his heart, and at this time he also felt very curious about the other side of the iron gate.

At that moment, he slowly pushed the door open.

But the moment the door opened, Lei Kun was instantly stunned in place, because there was another door behind this door.

This made Lei Kun instantly think of the two doors outside this base, and he couldn't help but sigh in his heart: "Could it be that the steel in this base is overcapacity?" Or are the people here crazy? So many gates were built! ”

He stared at the door twice, and found that the iron door inside was actually locked with a mechanical lock.

This made Lei Kun's head big for a while, and when he saw the mechanical lock on this door, he knew that if there was no key, it would not be able to open it in a short time.

But now he has no other way but to crack it as soon as possible, and now he only hopes that the battle above will not end so quickly.

Lei Kun let out a few long breaths to stabilize his emotions, then leaned down and began to crack the mechanical lock.

Five minutes have passed, and Lei Kun's body has been covered with a layer of cold sweat, but his hands are not shaking, after all, there is a slight difference, as long as there is any deviation, then his previous time is wasted.

At this moment, Lei Kun suddenly stopped the movement in his hand, and a smile appeared on the corner of his mouth.

With a "click", the door lock opened.

Lei Kun hurriedly unlocked the door, and the moment he opened the lock, he took a deep breath, and then slammed the door open, while aiming the muzzle of the pistol in his hand in front of him.

Suddenly, a blinding light came.

Lei Kun, who had always been in the dim space, subconsciously squinted his eyes when he saw this sudden bright light, but his gaze was still locked in front of him.

After two seconds, Lei Kun finally got used to the harsh light, and he slowly walked inside.

When he walked in, he saw Tang Yu tied to a chair in the middle at a glance.

It's just that Tang Yu was drooping his head at this time, not knowing whether he was in a coma or asleep.

Lei Kun was shocked, but he didn't rush into action.

He glanced cautiously around, the room was unusually bright, and all around it were white walls, even the floor was paved with white stone bricks, and there was nothing else.

After more than ten seconds, Lei Kun made sure that he didn't find any danger, and then he began to slowly approach.

He had just taken two steps when he suddenly felt a sinking under his feet, as if he had sunk into the ground.

This made Lei Kun suddenly feel a bad feeling in his heart.

Sure enough, at this moment, a gap suddenly appeared in the wall in front of his head, and two pitch-black muzzles had protruded from the gap, and these muzzles were aimed at him.

Lei Kun was relieved to see that there were no bullets in the muzzle.

But he couldn't stand forever, but he didn't dare to lift his feet, so he could only look around.

But alas, there's nothing around.

Lei Kun slowly crouched down, looked at the angle of the muzzle and the direction of the shot above his head, and then tried the stone bricks in front of him with a dagger.

After making sure that there was no danger ahead, he lowered his body and rushed over with a single lunge, landing firmly on the few stone bricks in front of him that were not in danger.

"Da", "Da", "Da" and "Da" gunshots rang out instantly.

When the gunfire stopped, Lei Kun looked behind him with a frightened face, only to see that the position where he had just stayed had left countless bullet marks.

Lei Kun looked at Tang Yu, who was still more than ten meters away from him, and sighed heavily, so he could only continue to try.
