There are 18 hours left until the fourth time rewind.

Liu Fei looked at his watch and threw the cement stone on the ground.

Seeing that everyone looked heavy-minded, he smiled and said, "You guys are worried, it's a big deal that you will be a good man again in eighteen hours." I'm miserable, I can't forget this incident. I have to re-explain it to you again, and it feels like a headache to think about it. ”

Su Si smiled bitterly, he didn't have such a good mentality as Liu Fei.

The facts in front of me are too shocking, and if you think about it deeply, it is even more terrifying.

Where did this 100,000-year-old underground passage world with a distinctly human-style world come from?

Is this another civilization, or is it true that the revival of the aura in this world began 100,000 years ago?

Either way, it's so chilling.

"Master Liu Fei, this underground world is too big, I'm afraid I can't even pass through this most superficial passage in eighteen hours, can we really find a way?" Wen Taihe also looked a little worried.

"Actually, there is no way. Liu Fei said.

"What should I do?"

Liu Fei sat on the ground, his fingers lightly tapping the ground.

Just when he was injecting the aura of historiography into the cement block, he made an unexpected discovery.

His right eye, the mysterious eye that the teacher gave him, began to change slightly because of the continuous historiographical energy.

The system display has also changed.

Eyes of the Future (Awakening).

Previously, the note of the Eye of the Future had been dormant, but this is the first time it has changed.

Awakening.

Has the teacher finally awakened what he gave himself?

The continuous output of historiographical energy is one of the reasons for its awakening, but Liu Fei feels that there are other factors that play a role.

The Eye of the Future seems to have some kind of connection to the backtracking state of time, and it is this connection that makes the silent Eye of the Future change.

In Liu Fei's eyes, the entire passage presented two states.

His left eye is the dull and dark world that everyone can see.

In the right eye, however, the whole world has become a world that is constantly twisting and fluctuating.

The space seems to be transformed into a long-axis scroll, which is constantly being rolled up and loosened by some mischievous child.

When loosened, the space is normal.

But roll it up......

A slight glint flashed in Liu Fei's eyes, and when he rolled it up, he could see the scene hundreds of kilometers away from the passage.

This strange state of space reminded Liu Fei of differential geometry.

Curvature space!

If he could penetrate the curvature, he would be able to reach hundreds of kilometers away in an instant.

He can't figure it out without specific coordinates, but now that the Eye of the Future can see the scene in the distance, is calculation still a thing for Liu Fei?

"Stay away from me, beware of accidents. Liu Fei got up.

Everyone looked at Liu Fei blankly, not understanding what means could change the status quo.

"Brother Fei, don't be reckless, let's find a way again. The rat couldn't help but persuade.

Liu Fei smiled slightly, facing the deep and dark huge passage, in which his voice echoed, with a certain color of emptiness: "There is differential geometry in space, even if you master the skill of curvature calculation, it is only a perfect mathematical model that is divorced from reality after all, and it is not much help for practical application." ”

Bang.

A vision suddenly appeared.

Klein bottle, a special mathematical curvature of the world. A mathematical space that should not appear in a three-dimensional world.

A vague emerald aura illuminates the darkness.

Liu Fei's voice was still ringing: "But perceiving that the distant world is another state, looking at the fluctuating space from the perspective of historiography is like using the perspective of history to deduce the road of the future, and then restore the road." ”

Historiography aura appears at the same time.

That's right, the picture scroll seen by the Eye of the Future is the history of space, through long distances, through the distant history of the same time.

If this distant history is synchronized with this side, it can be converted into mathematical coordinates.

Liu Fei's voice continued: "Of course, having the coordinates of the two is not enough, how to convert the mathematical space into the actual space, and then fold the two coordinates together, is the key in the key." ”

The third aura rises up.

At this moment, all the scholars who saw the aura were looking at a god.

The color of the aura has never appeared in the human world.

It is obscure with a starry glow of the blue earth, like the untouchable starry sky.

There is a strange power to this rich color, in which time, space, speed, everything that is connected with the most basic constants of human beings seems to be contained.

"This is a new physical aura? Physics aura has changed, how can it be!" the teacher of the gravitational school said in a lost voice.

In more than 60 years of Reiki revival, there has never been such a phenomenon.

Whether it was the pride of the golden generation or the powerful elite veterans, they were all stunned as a power that they had never seen before appeared in sight.

The dark and blue fluctuations spread, mysterious and spiritual.

In Liu Fei's eyes, the world has changed.

It's like a bug that has been living in a two-dimensional world for a long time and suddenly comes to a three-dimensional world.

It's a never-before-seen perspective.

Since he completed the general and special theories of relativity, Liu Fei has sealed all the forces in this regard, for fear that the early leakage will cause the wrath of the three clans.

But in this mysterious space, it seems that there is no need to worry so much.

This chaotic world is not under the control of the three tribes.

He held out his hand, and the dark and deep corridor world was perhaps the first crisp sound in a hundred thousand years.

So the space hundreds of kilometers away was suddenly folded by a pair of invisible big hands, and the magnificent and indescribable world was pulled in front of Liu Fei.

This moment.

The energy of historiography is as majestic as the sea, the power of mathematics is blooming, and finally ...... Space power.

"If there is matter in space, the matter will inevitably cause the space to bend, that is, the space will produce curvature. Liu Fei's voice echoed: "In the normal world, I can't pull this space, but this world filled with the power of historiography can, because another force involving space, time, is affected by historiography." ”

In front of everyone, a huge arc-shaped membrane appeared, as if it had been smeared at random and as if it had a special shape.

On the other side of the giant arc membrane is a space hundreds of miles away.

Liu Fei really folded the space and pulled it in front of him!

Will he be able to pass through this spatial membrane?

Liu Fei took a step lightly.

The boundless arc-shaped spatial membrane shook violently, and then shattered like glass. 、

But Liu Fei's figure disappeared.

In the middle of the night, Wen Taihe let out a cheer of surprise: "The perception of a living form five hundred and sixty-two kilometers away is Liu Fei's life characteristic!

There was a loud cheer from inside the passage.

100,000 years is too long.
