Among them, the three cultivation levels of the lower god, the middle trick, and the upper immortal are called god levels.

And the three cultivation levels of Earth Saint, Quasi-Saint, and Heavenly Saint are collectively called Saint Level.

As for the Immortal Venerable, the Dark Venerable, and the Heavenly Venerable, they were merged into the Venerable level.

Regarding the division of biotechnology levels, it is also based on the upper limit of these cultivation levels that those immortal cultivators on the planet can achieve with the help of the spiritual power of heaven and earth on the planet where they live, and the level is changed to five layers.

Because although the energy of the universe is conserved, the distribution in various places is different, and regarding the level of cultivation in biotechnology, because the spiritual power of heaven and earth required for each level of breakthrough is increased by geometric multiples, the spiritual power of heaven and earth provided and supported on its planet also has a certain upper limit.

It is also based on these upper limits that the level of biotechnology is divided into the general division with the level of mechanical technology.

One of them, that is, the first level of biotechnology, is that the immortal cultivators on its planet can only reach the tribulation period at most with the help of the spiritual power of heaven and earth on their own planet, that is to say, when the immortal cultivators on a planet, with all kinds of opportunities and their own efforts, under the inhibition of sending out all external factors, the maximum cultivation level that can be achieved is the tribulation period, then it can be said that the biotechnology tribulation on this planet has reached the first level.

This is also the level of biotechnology on the earth in front of us.

As for the level of biotechnology, unlike mechanical technology, according to the continuous development of highly intelligent animals on the planet, its mechanical technology can be continuously upgraded according to the improvement of various basic formulas and derivations and advanced formulas on reactions and effects.

In other words, with the continuous development of highly intelligent creatures on a certain planet, it is possible to continuously improve the level of mechanical technology on this planet.

But the corresponding biotechnology level is a little different.

When a planet is formed, the concentration of heaven and earth spiritual power contained in it is already fixed, and this can be roughly understood as a level of biotechnology, which does not require the acquired efforts of the highly intelligent creatures living on a certain planet, but has been determined when the planet is formed.

According to the conservation of cosmic energy, it is impossible for the planet to have a lot of heaven and earth spiritual power out of thin air, so if it is a planet like Earth whose biotechnology level is not too high, in fact, the development of mechanical technology is the only way out.

Of course, if you really want to improve the level of biotechnology on a planet the day after tomorrow, it is not impossible, but what you need to do is far more difficult than developing mechanical technology.

Because, according to the conservation of cosmic energy, if you want to increase the concentration of heaven and earth spiritual power of the entire planet the day after tomorrow, so that the biotechnology level of the planet can be improved, then what it needs to do is to annex another planet.

Because no matter what other secret method there is, the spiritual power of heaven and earth contained in a planet is incomparably huge, even if the biotechnology level is only a first-level planet, so if you want to really raise the biotechnology level of a planet by one level, then you can only annex another planet with a biotechnology level greater than or equal to the biotechnology level of that planet.

Such a process is extremely difficult and long.

The second level of the biotechnology level is that the immortal cultivators on its planet can only reach the Tianzun level at most with the help of the spiritual power of heaven and earth on their own planet.

The third, fourth, and fifth levels of the biological level are actually not much different, but the difference is that the immortal cultivators on their planets can only reach the destroyers, managers, and creators with the help of the spiritual power of heaven and earth on their own planets.

For the cultivation level, Tianzun is actually a more conventional tribulation, and once he reaches the destroyer, then he has the power to truly destroy the planet.

Tianzun, it's more about the gap between the spiritual power and the strength, although the gap between each level is very large, but it will not change too much.

And when an immortal cultivator's own immortal cultivation level reaches the Destroyer level or above, it is not only an increase in strength.

That—

In fact, it has already begun to touch the edge of exploring the beginning of the universe.

The Destroyer has the power to easily destroy planets, and its strength can easily create black holes, space shuttles, and collapse technology, all of which are already possible.

Managers, as the name suggests, are already capable of managing the space and maintaining order.

The creator, that is the same level as the three creation gods, since the emergence of the universe, until now, there is no civilization that has reached the fifth level of biotechnology.

In fact, regarding the third level of biotechnology, that is, the immortal cultivators on its planet can only reach the destroyer at most with the help of the spiritual power of heaven and earth on their own planet, then the strength on that planet can already compete with the civilization that has simply developed mechanical technology and reached the seventh level.

And for managers and creators with higher cultivation levels, then it is even more impossible to resist.

It can be said that such a congenitally determined level of biotechnology on a planet is actually far more important than the level of mechanical technology that can be raised with the development of the day after tomorrow.

It's just a good biotechnological-level planet, how can it be so good?

Seeing this, the kraft book in Mu Chen's hand has already turned to the last page, and after reading this kraft book, in fact, Mu Chen doesn't know what his mood is now.

"The level of mechanical technology is not good, even the level of biotechnology, is it the same?"

Closing the kraft book in his hand, Mu Chen couldn't help muttering to himself.

Regarding everything recorded in this kraft book, Mu Chen and Song Qi have never heard of anyone else, it's not that others don't want to say it, the real reason is actually such a news, before Mu Chen and Song Qi, no one should have known, right?

After millions of years of cultivation, the immortal cultivators of all races on the earth have already known that the upper limit of the cultivation level has crossed the tribulation period, but why are these immortal cultivators still walking the path of biotechnology without hesitation?

Honorable?

According to what is said in this brown book, then the Forgotten Lands that once dared to provoke the distraction of the Void Lord, their biotechnology level is only the second level!

Biotechnology level, you know that, so casual, but so important.

Shocked, Mu Chen felt that he couldn't accept everything recorded in this book at all, and Song Qi on the side was even more so.

There were some muna, but Mu Chen still knew the general knowledge of stuffing the brown book in his hand into his clothes.

Regardless of whether what is recorded in this brown book is true or not, but when the time comes, bring it back to Qingyu and other strong people to study, Mu Chen feels that he will still gain something.

It seemed to sense that Mu Chen and Song Qi had finished reading, and the bookshelf-like object in front of them was slowly dissipating, and Mu Chen also hurriedly looked at the kraft book in his clothes, and saw that the book still did not dissipate with the disappearance of the bookshelf-like object, so he breathed a sigh of relief, and sat on the ground, just staring at Song Qi beside him in a daze, it seemed that it was still difficult to digest all the content recorded in the kraft book.

"I don't know if what this book says is true, but I think it really seems to be a perfect fit for the current situation on our earth!"

Stunned for a while, Mu Chen finally opened his mouth slowly and said in the direction of Song Qi.

I don't know if I'm talking to myself, or if I know that I want to discuss with Song Qi......

Perhaps it was just to let Mu Chen and Song Qi know the mysteries of these universes, but soon after the bookcase-like objects disappeared, the chaos around them began to slowly disintegrate.

The surrounding environment changed again, and slowly, Mu Chen and Song Qi found themselves in the middle of the boulder lake again, and the stone stairs that stood down were still the same pieces, and the ice and snow castle didn't know when it had disappeared, but there was still a chaotic black hole not far in front of Mu Chen and Song Qi, but if you looked carefully, you would find that the current chaotic black hole seemed to be different from the chaotic black hole that Mu Chen and Song Qi stepped into in the ice and snow castle before.

However, Mu Chen and Song Qi didn't have much time to pay attention to the changes in the surrounding environment now, they were still thinking for a long time that if what was written in the brown book was true, then it would bring such a blow to the immortal cultivators of the four races on the earth.

"Forget it, Brother Mu, don't think about it, it's not something we can change anyway, maybe it's a good thing to find out about this fact earlier!

Since the biotechnology of our earth is already like this, it is impossible to annex another planet, and we now regard the bird without a planet as a great enemy!

Knowing this information now, maybe the four clans can increase the development of mechanical technology, so that they will not blindly stumble on the road of biotechnology, that is, cultivating immortals, and can make our earth more powerful!"

Looking at Mu Chen, who was standing beside him, but it seemed that he couldn't stop sighing, Song Qi also suppressed the tremor in his heart and comforted Mu Chen.

It was also what Song Qi said, Mu Chen felt that he felt a little better, just took two deep breaths and nodded slowly.
