If it weren't for this incursion, Ye Yuan wouldn't even know that there was such an underground base under this North Mountain. m.jjyfw.

The entire base was covered in steel thirty meters underground, and every twenty meters on the top of the wall was a downlight, and a faint light illuminated the steel passage.

On both sides of the passage are various laboratories, including the corpses of many mutated creatures and organs soaked in bottles next to them.

However, there was not a single staff member in sight in the entire basement, and although there were many notebooks and protective equipment scattered around the laboratory, there was no one in sight.

Ye Yuan came to a cell matching laboratory, and the cell fluid in it was still fresh, and it stands to reason that those people would not be able to leave for more than an hour at most. It seems that the people in this underground base saw them through surveillance and then evacuated ahead of schedule.

The entire basement floor was the size of more than a dozen football fields, crossing three mountain ranges, and it was obvious that nothing of value was found here, so they continued to walk down the stairs to the second basement level.

Most of the basement floors are biological laboratories, while the second basement floor is full of all kinds of weird machines, but Ye Yuan is still relatively familiar with these machines, after all, he helped Liang Zhenting find a lot of equipment.

It seems that their estimates are correct, these creatures have been mutated, and the things that induce their mutation have not yet been found, but the instruments to control biological waves are all here, if Liang Zhenting is allowed to come here, he should soon be able to master the technology here and find a way to control those creatures.

After collecting some information, Ye Yuan and the three of them continued to walk down.

On the third floor, there are various rooms, such as dormitories, which also store a lot of daily necessities, showing that there are many people living here.

On this floor, Ye Yuan paid attention to it, there were about thirty rooms in total, that is to say, this underground base once had at least thirty people, and they watched their every move through surveillance.

When they tried to go down to the fourth floor, they found that there were no stairs from this floor, and how to go down became a problem.

The rooms on the third floor are not big or small, and if you want to find a way to go down, you must act separately.

Ye Yuan came to the room in the northwest alone, mainly looking for those large suites, if there was really a secret passage or elevator or something like that, it must be hidden in the big room.

At this moment, Ye Yuan was in a large suite of more than five hundred square meters, and in the hall, he found a computer marked with a nameplate, and the name on it was "Yerek".

The things in the room were cleaned up, and it seemed that the owner must be a person who paid great attention to details, and he was very regular, as can be seen from the dense schedule above the computer.

The computer had a password, and Ye Yuan couldn't enter it, but under the computer desk, he saw a financial table, on which some types of incoming and outgoing accounts were recorded.

Just as Ye Yuan was looking through it, there was a sound not far away, probably far away, and it sounded a little unreal.

But Ye Yuan's perception was extremely sensitive now, and he immediately put away the financial statements and rushed out of the room.

When he walked around the steel corridor, he saw that two iron doors not far away had been overturned to the ground, Su Xuan was sitting on the ground, and a monster with black skin similar to a lizard appeared on the ceiling.

The lizard had four eyes, two on the face and two on the top of the head, looked around, and then rushed towards Su Xuan.

The speed is fast and the explosive power is strong, just as soon as he jumps up, deep traces are left on the steel wall, and Ye Yuan throws out the ghost slashing knife without hesitation, adding all the strength of the Matchless Tribulation.

Almost a millimeter later, the Demon Slasher grazed the lizard's head, and it sensed it beforehand, paused in the air, and then retreated.

Almost at the same time, Su Xuan's body was wrapped in chains, and then his figure retreated rapidly.

Ning Haiyue also came to the scene and faced the lizard with Ye Yuan.

The lizard should also be a mutated creature, and at this moment, facing the attack of Ye Yuan and Ning Haiyue, the tongue in its mouth like a whip kept shooting out, and the speed was so fast that Ye Yuan couldn't see it clearly.

Relying on instinct to dodge, the tongue left deep pits in the steel floor, and the impact was comparable to a pistol bullet!

In the process of dodging, Ye Yuan continued to use the Heavenly Sword Technique, and the Ghost Slashing Knife swirled in the air to attack, but he still couldn't catch the lizard.

After fighting, Ye Yuan was sure that this lizard was at least a third-level mutant, and if he wanted to defeat it, he would probably have to fight hard.

Ye Yuan and Ning Haiyue were attacked, but they still couldn't trap the lizard, and their defenses were constantly impacted. The lizard not only attacks with its tongue, but also at close quarters, and can walk on the ground and walls, so that they can't hit it, but it is always within range.

There was always a mistake in the hundred secrets, and just when Ye Yuan's Ghost Slashing Knife launched another aerial attack, the lizard broke through Ning Haiyue's chains and rushed in front of Ye Yuan.

The lizard slapped Ye Yuan with a claw, this move he couldn't avoid, but at this moment, another chain came from behind Ye Yuan and entangled the lizard.

With a slight tilt of his head, his claws grazed Ye Yuan's face, and behind him, the Ghost Slashing Knife spun and hit the lizard's head.

Hearing only the sound of metal colliding, the ghost slashing knife was bounced out and inserted into the ground, and the lizard was not injured except for a piece of skin on its head!

This is really terrifying, in addition to the amazing attack of this mutant lizard, the black skin is like a piece of iron, and even the frontal attack of the ghost slashing knife can't hurt it, it is estimated that this black skin can block small-caliber bullets.

The attack, defense, and speed are impeccable, Ye Yuan and Ning Haiyue really can't do anything with it, and the only way is to withdraw.

Ye Yuan and Ning Haiyue rushed in front, as bait, and Su Xuan followed behind, continuing to look for a way down. Since they have come here, they will not leave easily without finding out who is behind the scenes.

Since this place is built on such a large scale, and the data is recorded, they are either experimenting or using other people's lives as entertainment, thinking of the mysterious loss of control of the cruise ship, there must be some shady curtain hidden in it. Therefore, they must not only escape, but also uncover their dark scenes.

Ye Yuan and Ning Haiyue dodged the lizard's pursuit, although the two sides cooperated very tacitly, but they were still inadvertently injured, although the wound was not big, but it really affected their reaction power and speed, and the difference was a thousand miles away.

"Old Jia, be careful!"

Just as the lizard rushed towards the canopy, it suddenly hit the top with its hind limbs, and then with the help of the power from above, it rushed towards Ye Yuan like a cannonball.

Ning Haiyue found out early, pounced on Ye Yuan, who was unstable, and then hit the wall together. Although this time was timely, Ning Haiyue's back still made a cut, and blood was dripping, but this wall was miraculously smashed open, revealing a spacious passage inside.
