National Class Change: Master of the Swarm! I Am the Fourth Cataclysm!

The underground devil's cave is exactly as its name suggests.

At this time, five people appeared in a dark, cramped small room at the same time.

In front of everyone was a huge iron gate with a small gap in the center.

Through the gap in the iron gate, you can clearly see that outside the iron gate is a wide tunnel. There are several oil lamps hanging on the walls on both sides of the tunnel. The dim and flickering light does not give people the slightest sense of security. And it added a bit of fear.

There were roars not far away, as if there was some terrible monster hiding in the darkness, ready to give everyone a fatal blow at any time.

This horrific scene immediately made several little girls tremble with fear.

"Brother Leg, is it really okay?" Gao Wei was also panicked and looked at Chen Tianming with a look of horror.

Chen Tianming didn't respond. He walked straight to the iron door and put his hand on the door handle.

Following a "creak", there was also a sharp sound of harsh metal friction.

The iron door was finally opened.

The moment the iron gate opened, the system's voice also sounded in everyone's minds.

[Underground Demon Cave-Hell Level, officially opened. 】

Opening the iron door means the official opening of the dungeon.

The moment the iron gate opens.

"Snapped"

Chen Tianming snapped his fingers, and fifty protozoa appeared in the tunnel in an instant.

"Due to the narrow terrain, can we only summon fifty at a time?" Chen Tianming thought to himself, and then with a thought, he sensed that a battle had taken place ahead.

Through his spiritual connection, he saw that a monster nearly two meters tall with a pair of red eyeballs on its face was already fighting the genetic protozoa.

However, in the face of the extremely high attribute value of the genetic protozoa, this humanoid monster was quickly restrained in place and unable to move.

When Chen Tianming was wondering why he didn't hunt this monster, he suddenly felt an emotion, which was a desire to reproduce and parasitize.

He stood there and agreed to the request after a moment's thought, and soon a wave of emotion passed until only a body fell to the ground.

Chen Tianming immediately controlled the remaining protozoa to explore their own way forward and parasitize.

Wait until all the protozoa around you are gone.

"Snapped!"

Another snap of fingers, and another fifty protozoa appeared in the tunnel.

After giving the same order, and after the protozoa left, Chen Tianming began to summon warriors.

However, Chen Tianming stopped summoning after summoning five hundred warriors.

"Okay, come with me!" Chen Tianming looked at the people behind him and waved.

"This map is a bit big. I'm afraid we can't stay where we are."

"Is there a distance limit between you and your summons?" Xue Shan observed this keenly.

"That's right," Chen Tianming admitted directly without denying it.

Soon the five people came to the first parasitized monster.

Chen Tianming took out the detector and started scanning the unconscious monster lying on the ground.

[Monster: Blood Slave]

[Level: Rare Level 6 (Rare Enhanced Type)]

【Power: 800】

[Agility: 500]

【Spirit: 300】

[Physique: 700]

[Skills: bloodthirsty, violent. 】

Seeing the monster's attributes, Chen Tianming fell into thinking, "Through past experience, the BOSS's attributes are generally about 2-3 times stronger than the mobs."

"In other words, the final big BOSS attribute of this underground dungeon should be between 1600-2400."

Slightly inferior to my genetic protozoa, it is indeed a copy of hell level difficulty.

But unfortunately, there is still a slight gap compared to my genetic protozoa. You only have one strongest one, but I have a litter.

Thinking of this, he felt reassured. In his eyes, there was not much difference between these blood slaves and the zombies in the lost city.

"Brother Leg, what's going on with this blood slave? Why is he lying here motionless?"

Gao Wei asked doubtfully.

"He was knocked unconscious by my summons using special means, and he won't wake up for the time being."

"Then why don't we take the opportunity to kill this monster?" Xu Mengyao also asked with a puzzled look. "What if this monster wakes up later, won't we be attacked from both sides?"

Hearing Xu Mengyao's question, Chen Tianming did not answer directly, but just smiled and told them not to worry.

"Brother Legs, do we need to do anything for this copy?" It was Li Meng who spoke.

"No need, just follow me for a walk here for now!"

"Take a walk?" Xue Shan asked doubtfully.

"That's right. It's my first time coming to this dungeon and I'm not familiar with the terrain. I don't know where the BOSS of this dungeon is?"

"Through the summons, I can sense that the terrain here is a bit complicated, so you have to follow me closely to avoid getting lost in this tunnel."

"After you find the final BOSS and defeat it, you can end this dungeon trip."

Gao Wei didn't care about this. After seeing that the place was safe, he immediately said cheerfully, "Brother Leg, why haven't you heard the sound of experience increasing yet?"

"Hehe!" Chen Tianming smiled mysteriously, "Don't worry, let the bullet fly for a while."

that's all.

The four of them followed Chen Tianming and dispersed in the tomb of this so-called elite powerhouse.

As time went by, everyone felt that it was getting weirder and weirder.

In the past two hours, every blood slave they encountered fell to the ground unconscious.

Likewise they did not hear any hints of experience.

They wanted to kill the blood slaves who were unconscious on the ground, but Chen Tianming stopped them. Whenever they asked, he didn't respond and just asked them to wait patiently.

In this way, two hours later, Chen Tianming completely figured out the terrain distribution of this underground cave!

Soon, under the leadership of Chen Tianming, a deep underground castle appeared in front of everyone's eyes.
