In this secret pattern laboratory, dozens of monsters were gathered, which made Meng Xuan somewhat frightened.

He didn't think that these monsters were dead, and the strong malice that was unleashed all the time reminded him that if he woke them up, he would surely die.

Although he is not afraid of death, if dozens of monsters are released at once and wander in the experimental base at any time, then he basically does not need to come in.

"For the time being, it seems that there is only one red-eyed monster that has awakened, and the others should be asleep, as long as I don't act aggressively, it shouldn't stimulate them to wake up." ’

Meng Xuan glanced at the secret pattern with some pity, it seemed that this thing couldn't be taken away for the time being.

The secret pattern is likely to be the source of the power of these monsters, and if you touch the secret pattern, these dozens of monsters will inevitably fight with you.

But it doesn't matter if you can't get it, you won't need it at all in a short time.

'The red-eyed monster can't be killed·······

Meng Xuan felt that he had not been very lucky recently, and finally had the opportunity to slaughter the red-eyed monster, but he didn't expect that this guy actually had a monster lair, if he entered it now, he could easily kill this guy who seemed to be sleeping, but the movement he made was also very likely to cause other monsters around him to wake up.

Meng Xuan pondered for a moment, the red-eyed monster was obviously seriously injured and should not be able to move for the time being, he could just take this opportunity to visit the experimental base first.

With a decision, he walked to the shadowy place opposite the door and cautiously crossed the door, ready to explore the space in front of him again.

It turned out that he had just walked thirty meters.

"It's the end?!"

Meng Xuan looked at the scene in front of him as if it was a collapse a little speechlessly, the entire metal passage was broken, and it was tightly blocked by huge rocks.

Meng Xuan went up to check it, these stones were hard and heavy, and it was estimated that they would not be easy to drill with a diamond drill bit.

He looked at the sides of the passage again, and the thick metal turned outward, as if it had been struck by a great force, and the whole thing was broken in two.

'Could it be that there was a big battle at the experimental base that year, and Nelson's powerful and extraordinary warriors shot and broke the passage with one punch, right?' ’

Meng Xuan thought, after all, the fist mark before was blasted out by a person, and it was not surprising that there was an existence stronger than that transcendent warrior.

Meng Xuan looked at the break carefully, and felt that the passage did not look like it had been broken from the inside, the direction of the break on both sides of the passage was towards the left, and it looked more like it had been broken by someone with a punch from outside the passage on the right.

But judging from the fact that the passage is blocked by rocks, the experimental base is either in the mountain or buried deep underground, who can swing his fist outside the passage?

'It can't be a battle in another passage, and the aftermath of an attack blows up the passage from afar, right?' Blowing up half of the base with one punch? ’

Meng Xuan thought whimsically, if this is the case, how strong does this person have to be? Humanoid nuclear bombs?

He shook his head, brushing these unrealistic ideas behind him.

In short, this road is now impassable.

Meng Xuan thought about it, when he came out of that laboratory, there were roads on the left and right, the one on the left was blocked, but the one on the right might still be able to walk.

So he chose to go back the way he came.

Knowing that most of the monsters in the passage on the right side of the experimental base were sleeping, Meng Xuan was much bolder and walked faster, and returned to the door of the original laboratory in a short time.

He didn't stop and continued to walk slowly towards the path to the right of the door.

This time he walked more cautiously, because he didn't know where the passage on the right hand side led or what was there.

If only there was a map······

Meng Xuan sighed, his visibility in this darkness was only about three meters, and it was very difficult to see, and at the same time, this kind of gloomy environment and unknown future would cause tremendous pressure on people's psychology.

Meng Xuan felt that he was bold enough, but he still unconsciously broke out in a cold sweat, and his hand holding the knife was a little wet.

He continued to walk a few dozen meters.

"Signs?!"

Meng Xuan was pleasantly surprised to see a dusty sign with a similar arrow symbol hanging on one side of the wall.

It's a pity that I can't understand these words!!

At this moment, Meng Xuan deeply felt the importance of literacy.

Unable to understand the characters on the sign, Meng Xuan could only pass over it in a daze and continue to walk forward.

He found that the passage on the right was also curved, bending in the opposite direction to the passage on the left.

The passage of this base was circular, right?

Meng Xuan guessed, and walked forward more than fifty meters, and he found that he had no way out.

This time, though, it wasn't a rocky block that blocked his way, but a door.

A metal door.

The metal door should be made of the same metal as the wall, there is no handle on the door, there is no keyhole, and there is not even a gap, if it weren't for the complex lines on this thing, and there was a door number hanging two or three meters above the ground, Meng Xuan would probably think that this was a wall.

The door plate was still written in Nelson script, and this time Meng Xuan recognized one of the characters.

It seems to mean a place of residence and a place of residence?

Meng Xuan had some uncertain guesses, Nelson's text was too difficult to remember.

'This can't be a dormitory for experimenters, right?' ’

Meng Xuan's eyes lit up and he thought.

If it's really a dormitory for experimenters, I'm afraid you'll be able to find something that works.

But how do you open this door?

Meng Xuan was worried, looking at the thickness of this thing, even if he asked Akto to get explosives, it might not be able to explode, and if he blew it up, the movement would definitely be very big, and the monsters in the secret pattern laboratory would definitely have to wake up at that time.

Meng Xuan was so anxious that he was itching, there was probably something good behind the door, but he couldn't open the door.

His mind was racing, trying to figure out how to open the door.

“NEI！ KU！ CHUAN！ WAI！ MIAN！ ”

“NI！ ZI！ WO！ SHI！ NI！ BA！ ”

"Open Sesame!"

"Om Ma Ma Horn 𠺗 吽"

“······”

Meng Xuan used his deep voice to change the initiating words of several rituals in a row, trying to wake up the ritual formation on the big iron gate, but unfortunately it had no effect.

'Isn't it going to be broken after thousands of years?' ’

Meng Xuan unwillingly shouted a few more starting words, but the door did not respond.

"The door of the experimenter's dormitory, isn't it the starting language used, but the card is swiped?"

Meng Xuan remembered that in the TV series in his previous life, those high-tech experimental bases seemed to be swiping cards, brushing faces, and brushing eyes.

"Card ······ How did I forget that thing. ”

Meng Xuan thought for a moment and patted his head.

When he first came to the mirror world, he searched the body of the black-robed corpse and found a purple gilt crystal card from the inner pocket of her black robe, but then he didn't know what it was for, so he casually threw it in the file bag, and he didn't care too much.

A few months passed, and I almost forgot that there was such a thing.
