The ruins are very simple, to the naked eye, it is an ancient temple with a simple painting style, and at its edges, there are even some breaks, as well as dense cracks, which seem to collapse at any time.

But Zhao Cheng felt a meaning that was almost immortal in this substance, conceptual immortality!

It's just that I don't know what this building has experienced, and the concept of immortality has also been damaged and partially subverted.

Li Yu looked at the strange symbols on the walls inside the building, and found that he couldn't understand these words-like things at all, but when he focused all his attention on a certain symbol, his consciousness exploded, and he seemed to have entered another world, the vast starry sky, the boundless earth, under the stars, the original fire of civilization, with the ignition of the heavenly thunder, the thing that was called a human mastered the power of flame.....

However, such a vision only appeared for a moment, and then he was popped out, and the whole person was exhausted for a moment.

At the same time, his system's built-in personal state monitoring module alerts him to excessive mental depletion.

The essence of these symbols, nothing else, is a highly cohesive message, and every word is a long history!

Before the destruction, the technology of the Vault Empire had reached its peak, and they had condensed the history of their entire race, from its birth to the eve of its end, into a magnificent chapter.

This is a true epic of civilization, an immortal epic.

And this building, if nothing else, is the civilization wonder of the Firmament Empire, the Temple of Civilization!

The Celestial Empire is very powerful, even more powerful than the Purple Moon Empire. The Purple Moon Empire is only the apex of creation, while the Firmament Empire has already begun to explore the origin.

This dimension of the void, touched here, is itself a proof of the exploration of origins.

How the Celestial Empire was destroyed is not in the chapters of this temple of civilization, or rather, there may have been, but it was subsequently erased.

The destruction of the temple is proof of this.

The damage is only the appearance, in essence, the so-called temple, and the chapters inscribed in the temple, are one, the chapters are the source, the temple is just a concrete object, it does not necessarily have to be a temple, it can be a monument, it can also be a scroll, and it does not affect the essence of the chapter of civilization.

What Zhao Cheng saw at this moment, on the eve of the end of the Firmament Empire, seemed to have observed something and made many preparations.

They reproduced several civilization temples and hid them in some special locations in dimensional space-time, and this near-zero dimension in front of them was only one of them, but it was recognized by the Firmament Empire that this was one of the places most likely to survive.

Because of the lack of authenticity, it is a disadvantage in many cases, but in some cases, it is also an advantage, and there is a certain mystery of origin involved.

However, at this moment, Zhao Cheng's main concern is not the end of the Firmament Empire, but the history of the beginning of the empire.

The fifteenth prince rebelled and wanted to overthrow Luo Zhen's hegemonic rule, yes, in the history of this Dome Empire, there are also Luo Zhen, and there are also relics of the Purple Moon Empire.

On this phenomenon, Zhao Cheng thought of many possibilities, such as the past may not be the past, the future may not be the future, the past and the future have been reversed by some force, so that in the eyes of all beings, the real past has become the future, and the real future has become the past.

The more he explores and cultivates, explores the dimension, and understands time and space, the more Zhao Cheng feels that in dimensional time and space, everything is not absolute, but blurred, and the boundary between the past and the future is not absolute, but the world is more like a quantum cloud, and all phenomena are the result of a directional collapse.

And the history of the Firmament Empire, until Zhao Cheng himself appeared, is no different from the copy that Zhao Cheng is now ordering.

Until, another Zhao Cheng appeared.

This Zhao Cheng is a traveler, with a very complex power system smelted on his body, after coming to this world, he first stabilized for a period of time, used a special prop, modified his identity, and finally successfully entered the Imperial Research Institute and became a researcher.

And this Zhao Cheng, and Zhao Cheng himself, also exist one

Some differences are more cold, more indifferent, and weaker, but Zhao Cheng can be 100% sure that this self and himself are of the same origin.

If you describe it carefully, this self is the blackened version of yourself.

In the Empire, the scholar route, and the warrior route, were incompatible, to be precise, artificially created by the Emperor.

The potential of human beings is limited, and the so-called scholar must point all the attribute points to the intellect.

It is true that knowledge is power, but genetic modification, spiritual transformation, once it evolves in a certain direction, it is very difficult to deflect the direction again, which is why the emperor is very relieved of a group of people who have countless knowledge.

But this kind of thing is only like this for human beings, Zhao Cheng's body has extraordinary compatibility, in short, it is a normal person, the total amount of attribute points is fixed, this one is more, the other is less, but Zhao Cheng's body, this kind of thing does not exist.

At the same time, Zhao Cheng has no loyalty to the empire at all, and it is logical that he can pass the loyalty appraisal of the empire by relying entirely on props and some special strength, and Zhao Cheng is unscrupulous to become stronger and contact the rebels.

In fact, Zhao Cheng doesn't care who is the emperor, Zhao Cheng is very pure, as long as he has more knowledge and stronger strength, whoever stops him, he will kill whom.

In the end, Luo Zhen was killed, and the fifteenth prince became the emperor, but in the end, he chose to self-destruct and left the future empty.

Zhao Cheng, as the chief of the reorganized Imperial Academy of Sciences, ruled the Imperial Academy of Sciences for a long time, and then one day, he suddenly disappeared, just like his sudden appearance.

After that, until the Firmament Empire reached its peak, it had never found any trace of Zhao Cheng in the vast and diverse world, as if this person did not exist at all.

This couldn't help but make Zhao Cheng think about it, and glanced at the sword cultivation technique on the panel.

Swordsmanship (??? ）（Iv1）Iv1(1000000/1000000)

(Note: The first chapter of the mysterious Supreme Sword Dao, with its own various nourishment, writing the chapter of the sword, raising the Supreme Sword and its law, unknowable, unspeakable, unthinkable, unpassable, eternal and unique)

The higher the cultivation, the more Zhao Chengcheng felt the gold content of this thing, especially the eternal and unique one at the end, and even Zhao Cheng felt that he could come to such a height so quickly, and this sword cultivation technique was the biggest add-on.

Because of this thing, you can directly transform your experience and perception into the realm in real time.

So, what week is it now?!

When he saw his other self, Zhao Cheng vaguely remembered something, remembered some sporadic pictures, the content of the picture was the dream he forgot when he obtained the swordsmanship, and in the picture, it seemed to be a sea.....
