Niu Fen woke up slowly, and was frightened at the first sight of opening his eyelids, and quickly bounced out of the treatment chamber.

"Damn!What a monster!" Niu Fen burst out in fright when he saw Dr. Brain.

In front of him, a metal disc the size of a footbasin was suspended, and on the disc was a semicircular transparent glass cover.

Inside the glass cover, there was a large ball of meat, and if you looked closely, it turned out to be a bloated head. The fleshy head has no hair, and the uneven white surface is clearly visible with dense blood vessels.

Underneath the big head is a thin body that is seriously disproportionate to the head, and such a baby-like body is not enough to support such a large milk bag, so the big head is fixed by a bracket, and various pipes are inserted into it.

What made Niu Fen laugh was that the little Ding Ding of this big-headed monster was really as small as a toothpick.

"I'm not a monster, I'm human, and everyone calls me Dr. Brain. "Dr. Brain's head is not open, but there is an electronic synthesis voice coming out, speaking Chinese. This is important!

"Human, you say you're human, what kind of species am I!!?"

"You are also human, primitive human. And I'm Homo sapiens. Dr. Brain said.

"Why am I a primitive person, how can I be a primitive person, don't think that I can fool if I don't read much. Niu Fen reasoned with Dr. Brain.

Dr. Brain said: "It is the law of survival of living things. For thousands of years, our human body and limbs have gradually degenerated, on the contrary, the brain has evolved rapidly, and now our survival and continuation are completely dependent on our intelligence, so it is called Homo sapiens, which is different from the Homo sapiens you said. ”

"Oooh. Niu Fen then remembered that he was in the future world. Niu Fen said: "You say that I am a primitive human, do you know that I am from another time and space??"

"I wasn't sure, but if you asked, it proves that my guess was right. ”

"Well, I'll admit, I did come from a past plane. Niu Fenda generously admitted and asked, "So, big head, what are you going to do to me now, are you going to slice me?"

"No, I won't do anything to you, our big leader wants to see you. Dr. Brain said.

"Big leader?"

"It's the supreme leader of our dungeon. ”

"Dungeons, you live underground?"

"Yes, underground. ”

"What about on the ground?"

"The surface environment is extremely harsh, and it is no longer suitable for us Homo sapiens. ”

"Is there a nuclear war?"

"No! it's because of a huge wormhole that appeared 5,000 years ago. ”

"Wormholes?

"5,000 years ago, when the earth was still healthy, a huge wormhole suddenly appeared in a certain sea. According to historical records, the wormhole existed in that sea area for 48 hours, and during these 48 hours, it swallowed 9.7% of the earth's total seawater and 7.1% of the atmosphere. The ecological environment of the earth began to deteriorate from that time, countless species became extinct, and even we humans could only survive by going underground. ”

Niu Fen: "I see. ”

At the same time, Niu Fen was thinking in his heart, isn't there a huge amount of water in the space in his mind, could it be that the world of the big head is the same as the world I am in? It's just that the time is different? The sea water that the big head said about the disappearance of the earth 5,000 years ago should not be the one in the space of his mind?

Niu Fen didn't know at this time that all this was indeed the result of him, and the culprit was the 36th brother.

"Okay, let's not talk about this, the big leader is here. ”

I saw that the same round tray covered with a glass cover swayed and floated in, and inside the glass cover was a crumpled head with a slightly smaller head, which looked very old. That's the big leader.

Niu Fen turned to look at the big leader and said, "Hello! Big leader!"

"Hello, welcome. The big leader also didn't have to open his mouth, and the sound came from the speaker that came with the flight tray he sat on.

Oh, yes, the people in the future world are very friendly.

Niu Fen also showed a friendly smile on his face, and said, "Big leader, my name is Niu Fen, I heard Dr. Brain say that you want to see me, is there anything wrong?"

Niu Fen felt that his energy was enough to open the absolute space again, and he could return to his own time and space at any time.

The reason why Niu Fen didn't rush back was to see what the so-called big leader wanted to see him.

The big leader said, "Are you really from the past time and space?"

"That's right. Niu Fen said frankly.

"I only have a partial understanding of the prehistoric world from the precious video materials left over from prehistory. Can you tell me what the earth was like at that time? ”

Dr. Brain's eyes were also full of yearning as he looked at Niu Fen, expecting him to describe.

Niu Fen scratched the back of his head, and after thinking for a long time, he didn't know where to start, so he simply said: "I won't be able to tell you clearly for a while, and when I come over next time, I will use my mobile phone to download a few books and bring them over to show you." ”

Dr. Brain grasped the key point in Niu Fen's words and exclaimed: "Come here next time!? Can you travel freely through time and space? How is this possible? This is not scientific!"

Isn't it very scientific for you to look like this? Niu Fen complained in his heart. said: "Ming people don't say dark words, I can travel through the past and the future." But it's not random, it seems to be very mentally draining. ”

"The medical warehouse you were lying in just now is a psychiatric treatment instrument, which can help you recover your consumed energy. "So you don't need to worry about overexertion, can you please show us?" ”

Niu Fen thought for a while and said, "Yes." ”

So his mind moved, and without warning, a black hollow the size of a football appeared in front of him. His thoughts swirled again, and a stream of water gushed out of the black hole.

Because of the opening of the space this time, Niu Fen himself is awake, so the space is not out of control like the first time.

"It's seawater! It's fresh seawater!" said Dr. Brain, excitedly. "Oh my God, there are so many microbes in the sea. ”

Niu Fen controlled the black hole and closed, and said, "It's just seawater, is it necessary to make a fuss about you, Doctor?"

"You, you, you, 5,000 years ago, the wormhole that appeared on the earth, was it caused by you!" the Brain Doctor asked excitedly.

The big leader also looked at Niu Fen suspiciously.

Niu Fen also had this suspicion, but he absolutely couldn't admit it at the moment, he directly denied it: "It's not me." How could it be that I caused it, it's not scientific at all. ”

"Yes, I should believe in science. Then the huge wormhole can never be artificially created. "Dr. Brain connected to the scientific field and immediately eliminated the speculation just now.

Niu Fen said: "Since there is nothing to do, I will go back to my own time and space." ”

"You must come again and bring the documentary of what you said about man and nature. The big leader said.

"Yes, will come again. After speaking, Niu Fen turned his mind and planned to open the space and go back. It didn't open.

The reason was that he had already opened it once, and he would have to wait until 24 hours later before he could open the door again.

Niu Fen didn't know that there was such a limitation, and he thought it was because his mental strength had not fully recovered. So he said, "Well, my mental strength doesn't seem to be fully recovered, and I can't go back for the time being." Well, can you give me a psychiatric device? ”

"No problem, just take it. The big leader said.

Niu Fen was happy in his heart, and said: "What, do you have any other good things here, and give me a few things." ”

"Yes, you can. You can do whatever you want. ”

I'm going to go! That's okay? I'm afraid this big leader is not stupid. Niu Fen's face bloomed with joy and said, "How embarrassing this is." ”

Dr. Brain said, "I have recreated a replica of a mecha that our ancestors used to roam the surface 3,000 years ago. It just matches your body shape, and I'll give it to you. ”

There are also people who take the initiative to deliver things. This brainy doctor seems a little more stupid.

Not long after, an octopus-shaped robot sent a brand-new mecha two meters high.

It is a humanoid mecha with a streamlined shell that shimmers with a metallic sheen.

Dr. Brain explained, "I've installed the latest artificial intelligence system on this armor, so you don't have to worry about not being able to operate it. The main material is made of ......"

Niu Fen didn't understand a lot of technical terms at all, and he had already attracted all the attention of this mecha's cool appearance. He loved it.

"This is an energy stone, you put it away. Another robot handed a small box with a great sense of technology to Niu Fen.

Niu Fen opened the box and saw that there were milky white crystals of different sizes and shapes neatly arranged inside.

"This is the energy stone that can power the mech. Not only to drive mechs, but also to power our dungeons with energy stones. Dr. Brain said.

The Great Leader added: "This energy stone pole is produced by special means, and the yield is extremely low, but the energy it contains is huge, and one is enough for this mecha to use continuously for 24 hours. ”

Niu Fen counted the energy stones in the box, and there were as many as 20. Immediately said: "Mmmmmmmm, I know." Thank you, Dr. Brain, thank you, big leader. ”

Niu Fen was in a huge surprise, but he didn't expect to get such a good thing when he came to the future world.

Dr. Brain squinted and was silent for a long time, and suddenly said, "I'll give you another super gene enhancer, this gene enhancer can strengthen the structure of human tissues, stimulate the human body's potential, and enhance people's strength, agility, and reaction speed, etc." ”

"Okay, okay! I want it. Niu Fen was so happy that he couldn't keep his mouth shut.

Dr. Brain said solemnly: "But you have to be careful, this enhancement potion must not leak into the air, otherwise it will quickly evaporate, and..."

"Okay, I see, I'll take notice. Niu Fen didn't wait for Dr. Brain to finish speaking, he shouted that he knew, and then couldn't wait to snatch a glass injection test tube with metal wrapped in the head from the robot's hand, and looked at it in his hand.

"Since Dr. Brain has given you two things, I can't be stingy. The big leader said. "I'll give you a hundred kilograms of gems. It's of little use to us, and it should be worth a lot on your plane. ”

100 kilograms! it! It's inhumane!

"Uh-huh, thank you too, big leader. Niu Fen's face was cramped with happiness. He felt that the people in this future world were simply too generous, and he fell in love with them a little.
