"call!"

Chen Ping let out a long breath.

He had never felt such a strong sense of oppression, which was only felt after the water was pumped out.

Seeing Chen Ping's expression, Dr. Octopus smiled at Chen Ping and said: "I'm really sorry, although our technological level here can pump out the water, the pressure in this room is still there. You also know that our underwater resources The material is special, so the pressure is unavoidable for us.”

Chen Ping nodded. These pressures are not a problem for him, he just needs to get used to it for a while.

"I heard from those mermaids before, are you making a vortex machine now?"

Chen Ping directly cut into the topic, not because of other reasons. If he wants to obtain the technology of liquefied vitality, he must first convince the doctor to believe in him.

As for the method of making people believe in himself, he may not be good at it, but using the power of technology as a threat to keep the other party from leaving him is the fundamental condition for him to stay.

The mermaid doctor sighed softly and said: "To tell you the truth, in order to guide the ocean currents and make our underwater world less cold, I chose to make a vortex device."

It was only then that Chen Ping realized that Dr. Octopus was targeting the ocean temperature issue.

Immediately, Chen Ping used his communicator to search for all related words about temperature adjustment.

From it, Chen Ping used his own communicator to project the information that seemed to be useful to Dr. Octopus.

"This is the current experience of human beings on adjusting the temperature. I wonder if it will be useful to the doctor?"

When Dr. Octopus saw this information, his eyes lit up immediately.

But at this moment, the doctor's door was suddenly knocked open.

"Humans, there are actually humans entering our mermaid country again!"

What broke in was a fierce-faced mermaid, his body was covered with criss-cross scars, and he was holding a sledgehammer in his hand.

At this time, his aura is fully opened, and he has actually reached the level of nine-star cultivation.

"Zaku, get out for me."

The mermaid doctor saw this vicious mermaid, and immediately shouted in a cold voice.

But Nazagu was not willing to withdraw at this time, he looked at Chen Ping with cold eyes: "My whole family was killed by humans, and now there are humans coming to our mermaid country, shouldn't I Revenge?"

The vicious mermaid immediately grabbed Chen Ping.

Not to be outdone, Chen Ping punched the vicious mermaid fiercely.

But when their fists and palms collided, both the mermaid and Chen Ping felt a little surprised.

This Zaku is also an extremely tyrannical existence among the mermaids, but in terms of strength, there are very few opponents.

The same is true for Chen Ping. Chen Ping's physical strength has reached a heinous level, especially after going through the state of skin refining in body training.

Chen Ping's physical toughness now is unimaginable.

And his strength is considered outstanding among cultivators of the same level as human beings.

But for a while, neither of them could do anything to the other.

"Okay, this is not the place for you to do it. If you break my experimental equipment, you will not be able to bear the consequences."

The doctor walked between the two, and his tentacles wrapped around their arms.

With the doctor's slight movement, the two were already separated.

"Boy, you'd better not leave the doctor's room, or I will definitely tear you to pieces."

The vicious mermaid glanced at the doctor, and then swam out.

The thick fish tail left a puddle of water on the ground.

And because Chen Ping wanted to fight that vicious mermaid just now, the projection of the communicator on his arm also disappeared.

At this time, the doctor smiled and said to Chen Ping: "Don't worry, Zaku's character is just like this, and he lost his family because of human invasion many years ago."

Human invasion?

Chen Ping frowned suddenly, that is to say, how many years ago, human beings had come into contact with this mermaid country.

Doesn't that mean that this method of liquefying vitality has long been introduced into the human kingdom.

But even though I thought about it, I have never seen such a thing on the market.

Doctor Octopus suddenly said: "Well, let me take you around my small island first, and let's talk about your human technology."

Chen Ping nodded lightly. He is not afraid of human technology being learned by these mermaids.

Because the most cutting-edge technology is controlled by each country or each royal family, the information that can be searched by using the communicator is only the way many years ago.

Just before going out, the two tentacles of Dr. Octopus suddenly touched, and a bubble appeared, directly wrapping Chen Ping in it.

"Don't be afraid, I just came up with this method because I saw that you don't like soaking in water."

Doctor Octopus smiled and explained to Chen Ping that he was like a respected elder at this time.

Chen Ping smiled lightly, signaling to the other party that he was not afraid, and then asked, "Doctor, how did you cultivate? Even the guards have a seven-star cultivation."

Hearing Chen Ping's question, Dr. Octopus has already confirmed that he must be the next one, needless to say, it must be because of that incident that Dr. Octopus began to have a strong interest in human technology.

Just at this time, a small fish swims to Dr. Octopus.

And Dr. Octopus seemed to hear what the little fish said, his face changed slightly, and then he said to Chen Ping: "There are some things in our clan, so I can't accompany you for now."

Chen Ping immediately said that he would let Dr. Octopus go about his own affairs first.

But at this moment, Dr. Octopus left, and the vicious mermaid had already come to Chen Ping's side.

"Boy, as I said before, as long as you come out, I will tear you to pieces."
