Hundreds of Thunder Butterflies flew in front of the thick metal door engraved with magic talismans, but they only hovered a few centimeters in front of the door, but they couldn't get close to it, because the Thunder Butterflies would turn into nothingness once they touched the door.

Ai Shuang, Wan Rongbing, Spider Yu and Tai stood behind Liu Mengyuan and waited for him to collapse the door, Liu Mengyuan, who was standing in front of the metal door, did not move, the first batch of butterflies were triggered, and the dazzling thunder light hit the edge of the door, and the electric tongue of purple and blue kept licking it. When the first batch of butterflies was triggered, a steady stream of butterflies flew out of Liu Mengyuan's body, and he used the high temperature of thunder and fire to bombard the four sides of the door with high frequency.

Although the magic itself can't touch the door, the effects of the magic skill, such as high temperature, can...... Although this method is inefficient, Liu Mengyuan can only make up for it with quantity.

"The amount of demonic power of the predecessors is really amazing!" Wan Rongbing let out a low sigh.

Eventually, the edges of the metal door began to melt, turning red and hot, and finally turning into molten iron, and then the entire door slowly fell backwards, and finally slammed into the ground with a thud. Behind it was a long, curved corridor with mirror-smooth walls.

A few people jumped over the door that fell to the ground and entered the corridor, and as soon as they stepped into it, a red alarm sounded all around, and then many robots in the shape of small spiders continued to spread around the dome-shaped corridor, each "little spider" with a laser emitter on its back.

"The classic scenario is about to happen." Ai Shuang whistled and said.

Sure enough, these "little spiders" emitted red laser beams, weaving into a laser grid with each other, and quickly filtered towards a few of them.

And Liu Mengyuan didn't move, a large piece of thunder and fire butterflies flew out of his wide sleeves, flying towards each little spider at a very fast speed, and then they were triggered at the same time, and the dazzling light was accompanied by the roar of thunder at the same time, when the light faded, the chirping in the ears of several people still did not dissipate, but those defensive robots had all been smashed into pieces and scattered all over the ground.

"Let's go!" Liu Mengyuan said.

There was no other means of defense, and inside was a large laboratory with iron frames on all sides, on which were computers being calculated, and around the labyrinth of iron frames, they saw a platform, and the cocoon was on top of it. The demon slayers used bone fragments to create a shelf for the cocoon, which looked like two huge antlers glued out of broken porcelain pieces, holding the cocoon in place one after the other.

It wasn't deserted though, a man in a white coat stood next to it, with one hand on a cocoon. He did put his hand on the surface of the giant cocoon, not only that, but his whole body and the giant cocoon turned into a translucent illusory appearance, connected into one, and this virtual image was interfered with by electromagnetic waves like the TV picture, which jumped from time to time.

The person who guards this giant cocoon with wave dynamics is the Kinoshita cicada.

"What a strange demon skill, it's simply an invincible posture." Liu Mengyuan said.

"This is not a demonic skill, and of course it is not something that the science of this era can explain, if anything, it is a superpower. I know you're going to take advantage of the chaos to snatch it, so I'm here first, and while I can't fight you, you can't take it with you! ”

Tai suddenly roared and rushed towards the cicada, but he passed through. Tai, who didn't understand this situation, fished it with his hands, and the Kinoshita cicada, along with the entire giant cocoon, was as unreal as a projection.

"Liu Mengyuan, please give up, I won't hand over this dangerous thing." Kinoshita said.

"Invincible?" Liu Mengyuan smiled yin, "I have seen many demons claiming to be invincible, but in fact, there is no absolute invincibility in this world, and your demon skills must also have flaws." ”…,
