Meng Xuan quickly retreated from the iron gate to his previous laboratory.

The black-robed corpse was still quietly curled up in the corner of the laboratory, looking no different from an ordinary corpse.

But this time, Meng Xuan took a deep look at the black-robed corpse.

I didn't pay much attention to it before, but now that I think about it, I have a lot of doubts.

In the entire experimental base, there was not a single corpse in sight, except for the dozens of monsters in the secret pattern laboratory, nothing else could be found, but it was this dried corpse that was preserved, and the door to enter the mirror world was opened next to this corpse, saying that there was no wonder Meng Xuan didn't believe it at all.

'The dark shadow that tried to pull me into the mirror before couldn't be this guy?' ’

Meng Xuan couldn't help but guess, feeling that it was very possible.

However, he didn't feel malice and crisis in the black-robed corpse, and the black shadow in the mirror was also pinched and exploded by himself, turning into a pile of black smoke for himself to absorb, this black-robed corpse should be completely dead.

I can't figure out what happened back then, anyway, this dry corpse shouldn't be a threat to him anymore, and Meng Xuan won't care about it.

Finding the file bag, reaching in and pulling out the crystal card with a gilt purple front inlaid with a striking Nelson Eye, he walked out of the lab again.

Quickly coming to the big iron gate, Meng Xuan began to look at the ritual pattern on the iron gate again.

"How does this thing work? There's no place to swipe your card, huh? ”

Meng Xuan was a little confused, and he took the crystal card and brushed the door for a while, but the door did not respond.

"It's not going to be broken for thousands of years, is it? Or run out of energy? ”

Meng Xuan frowned, and when the crystal card in his hand swiped to a place on the left hand side that looked like a formation node, he seemed to see Nelson's eyes on the crystal card flash slightly.

Meng Xuan's eyes lit up, and he pressed the crystal card in that position.

The crystal card began to glow slightly, like a tinder, transmitting the light to the lines on the large iron door.

Centered on the location of the crystal card, the lines on the door lit up with a golden light.

Meng Xuan felt a tingling sensation coming from his hand, so he subconsciously retracted his hand and crystal card.

The array pattern was completely triggered, and the golden light slowly spread to every corner of the array pattern on the door, and the entire gate looked covered with golden patterns and flashes, full of strange mystery and beauty.

After the pattern on the door was completely lit, it flickered a few times very regularly, and then the light on the pattern completely dimmed.

And then, there is no then······

"That's it?!"

Meng Xuan almost scolded his mother when he saw this, and said okay to open the door? This thing can't really fall into disrepair and break, right?

Meng Xuan kicked towards the gate with a little anger, trying to use the physical repair method to repair the big iron gate.

Smack!

Meng Xuan stumbled, almost hitting the ground without a single heel.

His foot didn't hit anything, and he passed directly through the big iron gate, and the whole person stepped into the other side of the iron gate.

Meng Xuan controlled his body and turned his head in surprise, the big iron gate stood quietly behind him, and one side of the iron gate was painted with a formation similar to the other.

I'm in?

Meng Xuan looked confused, walked forward and touched the iron door, hard and solid, there is nothing wrong?

He found a similar formation node on the other side of the iron door, and pasted the purple crystal card in his hand again.

The slight golden light shone through, penetrating the entire formation, and after the formation flickered a few times regularly, it dimmed again, and the iron gate still stood there, and there seemed to be no change.

Meng Xuan learned to be obedient this time, and gently stretched out his hand towards the big iron door.

It looked like a physical big iron door, but Meng Xuan's palm easily passed through.

Meng Xuan stepped out in one step, and his body easily passed through the big iron gate, appearing on the other side of the big iron gate, as if the iron gate did not exist.

After passing through the iron gate, Meng Xuan touched the iron gate, and the iron gate returned to an entity.

Bang bang!!

Meng Xuan punched twice, but the iron door did not move at all, and his fist was shocked to the core.

This iron gate can still be transformed into virtual and real·······

"Black technology, ah······"

Meng Xuan sighed, feeling like a turtle.

He suddenly remembered the information about Nelson's civilization, and they believed that existence and nothingness should be examined with multiple eyes, and it seemed that they themselves had reached the point of transforming the virtual into the real, and could see more things.

Meng Xuan didn't stay any longer, anyway, he couldn't understand the formation patterns on the door, and after satisfying his curiosity, he swiped the card again and entered the other side of the iron gate.

Touching the big iron door that had become an entity again, Meng Xuan set his eyes on the space behind the door.

It was still a dusty metal passage, black and with very little visibility.

Meng Xuan was a little more cautious than before, who knew if there would be any strange existence behind this door.

It's just four or five meters away.

Click! Click!

There was something strange coming from the shadows of the passage.

Meng Xuan was so shocked that his hair exploded, but it was a little strange that his strange sense ability did not give him a strong sense of crisis.

He firmly grasped the folding knife in his hand, and put on a knife-holding pose, fully alert, concentrated, and ready to open the blood source ability at any time.

Boom! Boom! Boom!

There was a sound of slow footsteps from far and near.

Meng Xuan gritted his teeth, his heart pounding.

The footsteps came closer, and he finally saw what was coming from the darkness.

Meng Xuan: "·······"

It was indeed a monster, but it looked very different from what I had seen in the Mystic Pattern Lab.

The guy is humanoid, with two erect feet, two arms on his back, and a tail resembling a scorpion tail behind him, and his skin is dark purple with black lines.

But Meng Xuan didn't think this guy was fierce at all.

Because it was so thin, it looked like a starving ghost who had been hungry for half its life, skinny and skinny, and its humanoid face was sunken, like a skeletal frame wrapped in skin.

This guy has blood-red eyes, a fierce face, and a thin face that is hideous and terrifying, but his movements are as slow as that of an old man in his seventies or eighties with Alzheimer's disease.

It's no wonder that the ability to sense strange senses does not indicate danger······

Meng Xuan stood in place, a little speechless as he watched as the monster slowly moved in front of him, his mouth wide open, revealing a mouthful of hideous teeth, and his hands were slowly raised with difficulty, ready to smash into Meng Xuan's head.

One second···

Two seconds···

Three seconds···

After waiting for three seconds, the monster did not succeed in raising its hands above its head.

“······”

Meng Xuan looked at the struggling monster speechlessly, and slashed it out at its neck.

Brush!!

The monster's head flew high, and Meng Xuan felt as if his knife had been slashed at some kind of rotten wood.

It's too weak······

Meng Xuan was a little speechless in his heart.

Syllable!!

The monster's flying head and headless decaying body suddenly burst open, turning into a cloud of black smoke and shooting into Meng Xuan's chest.

"It's ?!!"

Meng Xuan's face changed, and he touched his chest inexplicably.
