"Huh?"

Just when Mu Chen and Song Qi were still wondering about the ethereal chaos around them, a bookshelf formed by the surrounding chaotic aura suddenly appeared in front of them.

In fact, it is not a bookshelf, it just looks like a bookshelf, but it is empty, and its colors are also colorful, which is not too different from the bookshelf appearance in Mu Chen and Song Qi's cognition.

And the sudden appearance of the bookshelf-like object also abruptly interrupted Mu Chen and Song Qi's thinking about the chaos around them, and instantly attracted Mu Chen and Song Qi's eyes.

In such a strange chaos, what is the meaning of this shelf-like object that appears out of thin air?

Or is this the same as the old man who appeared in the ice castle before, and what message is it hinting at Mu Chen and Song Qi?

Looking at the bookcase-like items in front of them, Mu Chen and Song Qi also cautiously and slowly leaned over, carefully taking a large number of items that suddenly appeared, and at the same time guessing the role of this object.

However, it didn't bother Muchen and Song Qi, only to see that when Muchen and Song Qi slowly approached the late stage of the shelf-like object, it was originally an empty bookshelf frame, but the power was absorbed from nowhere, and it was actually slowly formed, and a book was conjured up under the noses of Mu Chen and Song Qi!

I only saw that this book was different from the shelf-like object that loaded it, and the book was actually wrapped in brightly colored and lifelike cowhide, and the paper in it was also very high-end.

Just by flipping through the book, you can feel its preciousness.

However, Mu Chen and Song Qi were also quite puzzled about why such a kraft book suddenly appeared that was incompatible with the surrounding bookshelves.

With the doubts in their hearts, Mu Chen and Song Qi also took it and read it after several temptations to confirm that there were indeed no traps in this book.

Holding this kraft book in his left hand, and turning the pages from time to time in his right hand, Mu Chen also let the book slightly turn sideways in the direction where Song Qi was, so that Song Qi could also see it clearly, and Song Qi also stood on tiptoe and read the words on the book carefully on Mu Chen's broad shoulder.

As for the words in the book, Mu Chen and Song Qi were also very surprised to find that this was actually the common language of the human race, and as for the content recorded above, it was also extremely clear and concise.

Among them, roughly, it is-

At the beginning of the universe, all things were created.

The ultimate masters of its universe are divided into three types: the Void Lord, the Chaos Master, and the Space-Time Emissary.

No one knows why the three of them were born or why they came to be.

The only thing that is known is that these three are the supreme rulers of all the universes.

Regarding these three creation gods, they are roughly divided into the Void Lord in charge of the living beings in the universe.

The Chaos Juggernaut is in charge of the dark matter and energy in the universe.

As for the space-time messenger, this is the time and space that manages the entire universe and maintains the stability of space-time.

The whole universe, where the three creator gods created, all its guidelines have been laid out.

In the universe, if there are creatures born on the planets, then these creatures can develop freely, and basically they will not be subject to any constraints.

It's just that for the direction of development, it has been limited by the three creator gods - mechanical technology and biotechnology.

For mechanical technology, the creator god has already divided it into many levels.

Moreover, this book seems to be specially prepared for Mu Chen and Song Qi, and for this hierarchical description of scientific and technological civilization, it is actually completely based on the explanation of the immortal cultivators on the earth as a reference.

"The book...... It's quite spiritual. ”

Seeing this, Mu Chen and Song Qi couldn't help but look at each other, sighed slightly, and then continued to watch.

First-level cosmic civilization

The first-level cosmic civilization is also known as the "planetary civilization", the civilization has the ability to mine and utilize almost all the energy and energy on the planet, that is to say, the civilization is the absolute "master" of the planet, can control the weather, land, and various natural phenomena on the planet at will, know the structural changes and rise and fall of the planet above and below the ground, and even have the ability to destroy the surrounding planets.

Generally speaking, it means that a first-level civilization has "supreme" abilities on the planet where it is located.

Second-level cosmic civilization

The second-level cosmic civilization, also known as the "stellar civilization", has reached the point where it can leave the planet at will and exploit the stellar energy near its planet.

Generally speaking, if the immortal cultivators on the earth enter the second-level cosmic civilization, the entire solar system is under the control of the immortal cultivators, and they can habit, shuttle and develop energy on all the planets of the solar system as they wish.

In other words, if the first-level cosmic civilization or the current immortal cultivator civilization discovers and observes that an unnatural spherical structure has been established around a certain star, it means that there is really a civilization collecting stellar energy, which proves that the second-level cosmic civilization really exists.

The second-level cosmic civilization has reached a relatively highly developed level, and this degree of development belongs to the high-acceleration type.

Level 3 cosmic civilization

The third-level cosmic civilization is also known as the "galaxy civilization", which can easily control the galaxy in which it is located, and can also develop and use all the energy in the galaxy at will, and can even absorb the energy needed for its own civilization from the existing black holes in the universe.

The way this civilization exists has greatly exceeded all the imagination of the current immortal cultivators, because the way this civilization exists is contrary to the basic theory, because a galaxy is very huge, and the farthest distance between the two ends of the galaxy is at least hundreds of thousands of light years, and at most millions of light years, which is completely different from the current science fiction stories of immortal cultivators, so the way of existence of the third-level cosmic civilization is unimaginable to the current immortal cultivators.

Fourth-level cosmic civilization

The fourth-level cosmic civilization is the "cosmic civilization", because this civilization can already reach the level of developing and utilizing seventy to eighty percent of the energy in the universe where it is located, and can even develop and utilize the energy of the entire universe.

Level 5 Cosmic Civilization

On the basis of the fourth-level universe civilization, the fifth-level cosmic civilization has reached a point where it can easily integrate and utilize the energy in the multiverse......

Sixth-level cosmic civilization

The sixth-level cosmic civilization can be said to be the category of "God's Realm" that the current immortal cultivators are discussing, and they can control time and space at will, and they can create different universes at will......

Seventh-level cosmic civilization

Consciousness dissipates and cannot be expressed.....

At present, the immortal cultivators have not yet reached the first-level cosmic civilization, specifically they should barely reach the zero-point seventh, you read that right, it is the zero-point seventh, and the current civilization level of the immortal cultivators is indeed unexpected by many people. Assuming that the immortal cultivators surpassed the first-level cosmic civilization and barely reached the second-level cosmic civilization, then it would take at least a hundred thousand years or even longer to leapfrog from the second-level cosmic civilization to the third-level cosmic civilization.

Seeing this, Mu Chen and Song Qi couldn't help but be surprised.

Although it is not very clear about the mechanical technology of the ball, because whether it is Mu Chen and Song Qi, or other immortal cultivators, what they know is that the earth is mainly based on the development of biotechnology.

But......

For the various objects created by the powerful people on the earth through mechanical technology, their power is far beyond Mu Chen's imagination, but the book in his own hand describes the level of mechanical technology on the earth as 0.7, so low, it is not convincing to Mu Chen.

Interstellar travel, as mentioned in this kraft book, then the alien civilization that will reach the earth in a few years, the Bird Don't Civilization, their mechanical technology level is at most the second season, Mu Chen really can't imagine what kind of existence a civilization has if the mechanical technology level of a civilization reaches the seventh level described in this kraft book.

That......

I guess it can be more truly civilized than the essence of the creator god, right?

Thinking about it, Mu Chen and Song Qi couldn't help but feel scared for a while, they didn't expect that the level planning of this mechanical technology civilization was so beyond their imagination, and they didn't dare to continue to imagine it, Mu Chen and Song Qi also hurriedly turned the next page.

The next page of the book is a description of biotechnology.

The mechanical technology on the earth is actually level 0.7, and Mu Chen now just wants to know that the biotechnology level of the earth should not be too low, so as to seek a little comfort.

After millions of years of cultivating immortals, no matter how bad it is, Mu Chen feels that if this biotechnology is almost divided into seven levels with mechanical technology, then according to the current situation of the earth, it should be simple to reach the third or fourth level, right?

With their own guesses, Mu Chen and Song Qi looked carefully at the kraft book in Mu Chen's hand.

Biotechnology: Different from mechanical technology, biotechnology is divided into five levels according to the upper limit of the immortal cultivation level of immortal cultivators.

It plays a role in determining the restrictive cultivation level of biotechnology, from weak to strong, and is divided into: foundation building, enlightenment, fusion, heartbeat, Jindan, Yuanying, out-of-body, distraction, merger, cave void, Mahayana, tribulation, lower god, middle trick, upper immortal, earth saint, quasi-saint, heavenly saint, immortal zun, dark honor, heavenly honor, world destroyer, manager, creator A total of 24 cultivation levels.
