Everyone didn't know how long they had walked, and the tunnel was like a bottomless pit with no end in sight.

Gradually, an invisible sense of oppression weighed heavily on everyone's heart.

Even Agu Qilan, who had always been cheerful and lively, hadn't spoken for a long time, Bai Chen knew what was going on, but he didn't try to enlighten everyone.

For ordinary people, the closed environment itself carries a sense of oppression, and anyone in this closed environment will have this sense of oppression, especially in the case of unpredictable future, this sense of oppression becomes more and more intense.

The darkness supports this atmosphere well, and at the same time, there are tunnels that continue to extend downward, which makes people gradually begin to lose their minds and slowly be swallowed by fear.

"How long do you have to go?" Zhao Wu couldn't help but ask at first.

While speaking, Zhao Wu inadvertently held on to the wall.

Click――

Suddenly, a crisp sound sounded, and the ground began to rumble.

Immediately after that, the stairs where everyone was standing began to float up and down, not only the stairs, but also the walls began to shrink backwards and forwards.

"Huh......" Bai Chen looked at the ever-changing walls around him in disbelief, and he could feel that the ground under his feet was moving in an unknown direction.

Everyone panicked, and Agu Qilan hugged Bai Chen even more, screaming at a loss.

"Don't be afraid, this is an ancient trick. Bai Chen said.

Different from the current mechanism technique, the ancient mechanism technique is even more backward.

The ancient mechanism technique completely relied on the changes of physical laws, and a special mechanism was arranged through guò ingenious design.

Most of these ancient techniques were used in such large-scale buildings. On the other hand, the current mechanism technique. It's been a very, very much progress. Whether it is the application of Neidan, as well as the orientation, machinery or even derivation, it has been done to the extreme.

It can be said that the mechanism of the Han and Tang dynasties has been at a very high level of civilization.

A big reason for this kind of progress is because it was started 30,000 years ago, that is, in the era of Tang Sheng, and has been extended to the present.

There is also the appearance of the Heavenly Machine Diagram, which is certain to have appeared in these 100,000 years.

When the ground beneath everyone's feet calmed down. The stone wall in front of them slowly opened, and a large hall appeared in front of them.

The entire hall is covered with thick rock, and the walls, the dome, and the feet are all densely covered with patterns and Maha.

"Here's this?" Bai Chen stroked the patterns and Mahawen on the wall.

"Star map!!" the Cube began.

"This is the star map...... The coordinates of all the star fields with this planet as the origin and a diameter of up to 100,000 light-years are recorded. ”

"The founding emperor of the Netherworld Dynasty is not a native of this planet!" Bai Chen also saw the Maha text recorded on it.

"Obviously, the founding emperor of the Netherworld Dynasty is not ...... It should be said that they are not indigenous to this planet......"

The browsing speed of the Rubik's Cube is faster than Bai Chen's, and he is just scanning it casually. He imprinted all the contents of the entire hall in Bai Chen's mind.

"I see...... They are the explorers of the second-level planet Shenyuan World. ”

"Second-level planet?" Bai Chen was startled, an explorer of a second-level planet.

You must know that this world is only a planet that is defined as a first-class planet. The discovery of this planet by a second-level planet means a war of aggression and a one-sided slaughter.

Just like the American Indians on the earth, when the Europeans discovered the American continent and the Indians, it was the massacre of the highly civilized race against the low civilization race.

And the meaning of the second-level planet is that it can already go out of the outer space of the planet and enter the level of space travel.

"This planet of the Shenyuan World is only a second-level initial enlightenment stage, and the founders of this Netherworld Dynasty are the first batch of interstellar explorers in the Shenyuan World, and they do not have the ability to start an interstellar war, or they do not have a ...... for the time being However, these 300,000 years have passed, and even if the level is worse, it should have reached the late stage of the second level. ”

"Huh...... What is this for?" Aguzilan touched a small pyramid in the middle of the hall, and at the top of the pyramid was a white crystal.

At the moment when Aguqilan touched it, a white light suddenly shot out from the crystal, directly and violently on the dome of the temple.

"Oops...... Let go!" Bai Chen shouted violently.

"Huh, what's wrong?" Aguqilan saw that Bai Chen was suddenly so nervous, she had never seen Bai Chen so nervous, and hurriedly let go of her hands.

"What's going on?" Yu Qi and the others looked at the strange sight.

The entire hall was already illuminated by white light, and the lines and Mahawen on the heavenly dome were even more shining with strange light.

Bai Chen's face turned pale, and he looked at this scene blankly.

"Bai Chen, the matter has come to this, no matter how much you regret it, it will not help, now the most important thing is to find a way to deal with it, maybe things are not as bad as we imagined. ”

It was a transmitter, a signal transmitter, and this hall was actually a data room that recorded the planet and the Netherworld.

The moment Aguzilan touched the transmitter, the transmitter instantly sent a qiē in the data room back to their planet.

In other words, it won't be long before the world will have visitors.

Of course, the meaning of the Rubik's Cube is that it is possible that these outsiders are not malicious, or even just passers-by, coming and leaving quietly without taking a cloud with them.

But the greater possibility is that it will bring disaster!

This is a starting star, a planet with countless possibilities.

"Bai Chen, don't worry too much, this signal transmitter is just a primitive device from 300,000 years ago, maybe in 300,000 years, the signal frequency of the Shenyuan Planet has already changed, and this kind of signal needs to find the natural wormhole in the universe before it can be transmitted back to the original planet, the closest wormhole to us is at least ten light years, that is to say, we have at least ten years of preparation. ”

"Even if there is ten years, it is impossible for me to raise the technological level of this world to the level of a second-level planet, and you also said that the other party is at least at the level of the late second-level level. ”

"This planet can't, but I can!" Rubik's Cube suddenly said: "You have forgotten, I am a product of a fifth-level planet, and for me, the Shenyuan Planet is actually no different from this planet, it is the level of primitive people." ”

"You are an energy-exhausted spaceship intelligence, don't get it in front of me, you don't seem to have much ability other than to help me solve some addition, subtraction, multiplication and division. ”

"It's true that the energy is exhausted, but that's already in the past, this transmitter is the best energy source, I really didn't expect that the Shenyuan Planet actually produced this kind of good thing, this is a pure energy crystal, hundreds of times more advanced than Neidan and Ellipse...... Not thousands of times. ”

"Can this be used as an energy source for the spaceship?" Bai Chen asked in surprise.

"Of course, with this energy crystal, I can return to my homeland. ”

"This ...... I'll talk about that later. Bai Chen said hesitantly.

Now that he has provoked a second-level planet, Bai Chen doesn't want to recruit another fifth-level planet.

"Rest assured, the indigenous people of my homeland will not be interested in this planet. ”

"Why?"

"Because the natives of our homeland are not pure humans, unless they are willing to pay a high price to transform this primordial star into a frozen planet. ”

"Do those people in your hometown want to live in a very low temperature?"

"Close to absolute zero. ”

Absolute zero, also known as the cosmic freezing point, can freeze light at minus 270°.

Bai Chen really couldn't figure out that there were races in the universe that could adapt to this kind of environment.

"Actually, my creators are a group of cyborgs, if the temperature is too high, they will directly collapse into the most primitive photons, and only super low temperatures, coupled with their biological characteristics, can keep their bodies from being decomposed. ”

Bai Chen stepped forward and grabbed the crystal: "In other words, there is no conflict of interest between the races of our world and your world, right?"

"So to speak. ”

"Then if I send you back, will your planet help us in this world?"

"No, it won't. ”

"Why?"

"Do you expect a group of races condensed by cosmic energy to have such complex emotions as humans?" Rubik's Cube rolled his eyes and said, "What's more, I'm just exploring intelligence, and it's not as important as you think, and even my emotional processing procedures are better than those of my creators." ”

"Trouble. Bai Chen glared at Agu Qilan, the trouble-breaking spirit.

Aguqilan stuck out his little tongue: "Stone, did I do something wrong?"

"It's okay! It's a little trouble, it's just that you accidentally recruited a monster that can destroy Han Tang with one move. Bai Chen shrugged.

Everyone didn't take Bai Chen's words seriously, a monster that destroyed the Han and Tang dynasties with one move, is there really such a monster in this world?

Bai Chen was very distressed at the moment, he thought that the trouble of the underground Nether Beast was big enough, but he didn't expect that there was a bigger trouble waiting for him.

Therefore, Bai Chen could easily blame this trouble on the heads of Shu Hehara and the others, obviously, if it weren't for these miscellaneous troubles, there would be no such mess at all.

"That's right, Bai Chen. Rubik's Cube suddenly said: "Since the founders of the Netherworld Dynasty are a group of outsiders, then the spaceship they came to this planet is likely to be here, if my guess is right, they are likely to have encountered some trouble, so they will stay in this world, with the level of technology at the peak of the third level that you have mastered now, it may not be completely incapable of confrontation." ”

"I'm a fart by myself, do you really think I can save the world by myself...... I am not a savior. (To be continued......)
