It's a deep underwater cave. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info, but here they have discovered discoveries that could turn the entire history of mankind upside down.

Through these well-preserved nano-murals, Yun Qi can be sure that sea fog has been present since 100,000 years ago.

As they continued to dig deeper, they soon discovered that the mural revealed more information.

One of the unusually large murals depicts a triangular pattern that glows strangely. This mysterious triangular pattern has three large pupils. And under the gaze of its pupils, the human seems to be starting to go berserk.

At the bottom of this mural, humanity is divided into two parts. Behind them stood a large number of mental models, and these mental models were actually attacking each other.

In the details of some of the murals, Yun Qi and others even found weapons similar to the current erosion warheads and hypergravity cannons.

Further on, a beautiful woman with long silver hair and sky-blue eyes appeared in the mural. I saw her holding one hand with a heroic middle-aged man. Endless light radiated from the location where the two were linked.

And in the distance of this light, a triangular symbol that had appeared earlier suddenly emerged from the vortex. This strange triangular symbol seemed to be staring at the middle-aged man and woman. A feeling of unusually evil and hatred is projected from the mural.

Seeing this, Yun Qi and the others were actually a little confused. What exactly do these murals mean? Why sea fog will have a civil war. What does the triangle signify for?

It's a pity that none of this has been answered. Because the mural had disappeared by now, Yun Qi and the others also found that there seemed to be a faint light shining through in front of them. It seems that there is a light source ahead.

It's a strange thing. Even the sun's rays could not be transmitted to the depths of the sea, but now I can see some light. You know, according to the meter readings, the location of the Yi-401 is now 20,000 meters underground. This depth has passed through the earth's crust and into the mantle part. But the strange thing is that according to orthodox scientific theory, the underground at this depth has already been filled with magma. And now, instead of seeing the magma, Yun Qi and the others saw a glimmer of light and shadow.

No one can explain the current situation, and even Bismarck's doppelganger doppelganger looks ahead in amazement, because the further they go, the brighter they find it. It seems that they are not going underground, but are surfacing.

Suddenly, Iona's eyes lit up, and she said with some astonishment: "The gravitational field has been detected to be reversed, and the direction of the ship's gravity is automatically balanced!

It turned out that the I-401 had just passed through a critical point, before this critical point. The direction of gravity is the normal direction. But after passing this tipping point, the direction of gravity is towards the outer side of the Earth. In other words, the up and down directions are now completely reversed. Originally, the bridge of the Yi 401 was facing upwards and sneaking downward. But now, in the new direction of gravity, the I-401 is facing down with the bridge down.

For a while, attracted by the new direction of gravity, everyone smashed to the ceiling like upside-down onions.

Falling from the captain's seat to the ceiling, Yun Qi felt that every bone of his body was moaning.

On the other hand, Hinata, the royal sister, landed completely on the ground with her chest, successfully cushioning the impact force. As for Iona, she sat on Hinata's body. But thanks to Hinata's huge and ferocious cushioning effect, the two of them were not injured at all. And Hinata, who made a human flesh cushion, still looks like he's enjoying it. Some words of complete incomprehension were recited. For example, what "The impact of sisterly love is so strong." "Sister, beg to be a mount!"

But before everyone could catch their breath, they began to lean to the other side. It turned out that after detecting a change in the direction of gravity, Iona controlled I-401 to urgently adjust its direction so that I-401 was headed down and feet were facing up. But now the reverse is the right direction. So the crowd slid back to their original positions from the ceiling.

After this toss, everyone was embarrassed.

Soon, the brightness on the surface of the water became higher and higher, and only a "bang" sound was heard. Yi 401 actually broke through the water and came to the surface of the water.

Above them was an unusually large space, and there were even clouds floating in the sky. Looking into the distance, you can even see that there seems to be a huge land overhead. And in the middle of this huge space, there is an orange-red fireball hanging in the air. Two huge pillars that looked like mountains stretched straight into the air with a huge orange-red fireball, sandwiching it in the middle.

This huge world is like a hollowed-out apple core, and the huge continents at both ends are like the two ends left after the apple has been eaten. And that huge Buzhou Mountain is the stalk that connects the apple core!

And beyond these huge continents are endless oceans. It's just that the ocean here glows orange-red, and it looks a little crazy!

Seeing this miraculous underground world, Yun Qi couldn't help but exclaim: "This is really incredible! There really is a world underground! And it is a world with a light source. It's not pitch black, but what the hell is that orange fireball? It can't be the core!"

Regarding this question, Hinata, who had been selling cuteness there, suddenly straightened up, raised his glasses and said, "Although I don't want to admit it, it is indeed the core of the earth." According to the results, that core has an astonishing mass, enough to sustain Earth's gravitational pull. Strangely, though, the air here contains a lot of gravitational tons. These gravitational protons evenly spread the gravitational pull of the Earth's core to the outside world, and at the same time kept the underground world from shrinking inward and collapsing. ”

According to Hinata, this underground world is scattered with natural gravitational tons, and these gravity tons cause the gravitational weirdness of the underground world. And so that the underground world did not shrink and collapse due to the high gravitational pull of the earth's core.

At the same time, thermonuclear reactions are constantly taking place in this core, providing enough light for the underground world. Make it possible for the flora and fauna of this underground world to survive.

And the oxygen content here is surprisingly higher than in the surface world. You can even see a large number of creatures that have been extinct in the surface world since then.

Through the unmanned reconnaissance plane launched by Hyuga, Yun Qi and the others even discovered some ancient creatures, such as dinosaurs, living in this underground world.

It's a paradise lost. It is a place where the gods have forgotten, and where the evolution of species has been interrupted.

Soon, everyone took the Yi 401 to the shore of the nearest continent. After logging into the continent of this underground world, everyone used their own feet to step on this underground world like another world for the first time.
