In terms of species, if the Elven Tree is for elves to advance, then the primordial beasts and mutants need to get greater changes in Aoki's body. This is also one of the reasons why Aoki is willing to spend his blood.

More importantly, Aoki understands that after Earth participates in the advancement of the World Tree on the home planet of the Libby, it will no longer be able to maintain its previous low-key state, and may even be involved in a more fierce battle as a result.

Improving strength is the most important thing to do now.

However, in this process, as far as Aoki is concerned, there is still some buffer time for the earth civilization to be prepared by Aoki. This is also what Aoki needs.

It's just that this time is too short, so short that Aoki doesn't have a trace of time to waste.

Just as Aoki kept calculating all kinds of data and designing an evolutionary direction that was more in line with the merits of their bodies for these primal beasts and mutants, the primordial beasts that had been completing tasks on the alien planet also returned to Earth in spaceships.

Some of these primordial beasts haven't seen each other for a long time, and they miss each other very much.

As soon as they met, they immediately stimulated the spark of affection, which was extremely brilliant and pierced the titanium dog's eyes of countless people.

"**Tiger!!"

"**Bear!!"

**Tiger** Bear has tears in his eyes.

"Woooooooooooo I miss you!! A bear and a tiger hugged each other, and tears continued to spray like a faucet, drowning a bunch of first-order shells and cockroaches.

All the primordial beasts did not have the slightest chill, but felt very loving......

"**Tiger, isn't your strength also improved a lot!" The male leopard, who had advanced to the fifth order, patted his good friend in the past with his fat paws, and said with a triumphant look.

Now, although the strength of the ** tiger has also increased a lot, it is still the peak of the fourth order. Therefore, with the current strength of the male leopard, he can almost slap the ** tiger away. This makes the ** bear can only hide next to him like a good baby, for fear of annoying the male leopard and adding sadness to himself.

Indeed, the difference between a fifth-order primordial beast and a fourth-order primordial beast was very huge, and the gap between a strong man and a child was average.

However, even so, even if it was a fifth-order primordial beast, it was only a preliminary stage of the development of the primordial beast.

Only by becoming a sixth-order giant beast can it be considered a truly powerful primordial beast.

Because after the fifth-order primordial beasts advanced to become sixth-order giant beasts, whether it was the strength of their bodies, the toughness of their bodies, or the size of their bodies, they could no longer be on the same footing as in the past.

It can be said that after becoming a giant beast, the fifth-order primordial beast is like a serf turning over and becoming a master, and its own strength has almost been qualitatively improved, and it can even become the main battle ship of the army.

After that, the sixth-order giant beast advanced to become a seventh-order giant beast, and its own ** was strong enough to wander around the native planet.

If a seventh-order giant beast advances to an eighth-order giant beast, it can use its own ** strength to wander near the nearby starry sky after leaving the home planet.

The eighth-order giant beast becomes a ninth-order giant beast, and the star core in the body undergoes a qualitative change, which can store enough energy.

From now on, the ninth-order giant beast can go out alone and travel to the stars without any restrictions, which is incomparable.

The ninth-order giant beast became a tenth-order giant beast, and its body underwent great changes again, and its strength was greatly improved, becoming the overlord of one side, and even fighting against the race civilization alone. Even in the Ossi Star Field, you can go sideways.

It can be said that the giant beasts were very weak at the beginning, and it was only from the sixth-order giant beasts that they began to show their power and become the existence of the war ship. After that, it became more and more powerful, and becoming a starry sky monster was almost an invincible existence.

These are the charms of advancement, evolution.

Now Aoki has gained a lot of genetic energy in the advancement. These genetic energies can completely cause some of the sleeping potentials in the bodies of these primordial beasts to be awakened, and even burst out with powerful life force, increasing their chances of success in the future. Even some primordial beasts were able to advance immediately after being transformed by the life force force.

If in the next year, more sixth-order giant beasts can be born on the earth. Then the strength of the earth will gradually increase, and even break through from the peak civilization strength to the level of almost invincible below the fourth-level civilization.

According to the information in the elven world, the fourth-level civilization is almost invincible in the Ossi Star Domain.

However, it is also very risky for any civilization to advance to a level 4 civilization in the Ossi Star Domain. Because of the curse of devouring civilizations, these fourth-level civilizations will cause various unexpected attacks by devouring civilizations at any time.

However, there is no mention in the information of the elven world where these attacks are, and they are completely blank. These are all issues that need to be seriously faced by Aoki.

Soon, in front of the World Tree on Earth, many elite primordial beasts were gathered and named by Aoki one by one.

All the named primordial beasts were quickly bound by the rattans that descended down the branches of the World Tree. These primordial beasts climbed up the trunk of the World Tree along these vines, and prepared a cave for him.

After the primordial beast entered the cave, the outer skin of the World Tree quickly closed up. It didn't take long for these primordial beasts to start sleeping in it as if they were drunk.

This is Aoki's genetic evolutionary engineering.

This is a process by which Aoki injects the life genes released from the Heart of the Earth into the body of this primordial beast.

In addition to genetic energy, there are many life motive forces in these life genes.

Originally, it was impossible for a giant beast that was less than a sixth order to absorb the life power.

However, these life genes obtained from Aoki's advancement from the lifting of the ban on the Heart of the Earth are completely different.

The life code contained in this life gene is completely tailored according to the organisms on the earth, so these life genes are absorbed by these primordial beasts and have no side effects at all, but are more easily absorbed by the cells in the primordial beasts.

In this way, the potential in the body of the Yuan Beast will be stimulated, and their strength will gradually increase, and after a series of transformations, they will be able to become the true overlord of the Yuan Beast.

Soon, when the primordial beasts walked into the World Tree one by one, a lot of plant seeds were sent into the World Tree, imitating the cultivation of space seeds back then.

On the other side, human mutants have begun to enter the World Tree.

It is said that it is a human mutant, but in fact, it is more accurate to say that it is a group of people who evolved in advance.

Aoki was able to predict that as more and more vitality was released on Earth, life on Earth would become more and more advanced. According to this scenario, life on Earth will generally become first-order evolutionary life in a few decades or even less.

At that time, there will be no such thing as mutation and non-mutation, but first-order evolutionary life will become universal for life on the entire earth. Even if life on Earth is well educated, many ordinary life on Earth can become second-order evolutionary life, or even third-order evolutionary life, or even higher.

By that time, the average life expectancy of humans had increased to four hundred years.

The old methods of measuring age are no longer applicable, and everything on the planet has changed upside down.

Even artificial intelligence has become a growing trend in the whole world. However, this trend is not like the apocalyptic sci-fi films, where human beings are gradually relying on artificial intelligence and robots, and constantly degrading, but rather human beings are gradually freed from these tedious manual labor and engaged in more advanced work.

Even human participation in the military has become mainstream. Outside the mainstream are research on the World Tree, Genomics, and Super Energy. In this way, instead of getting weaker, humans are many times stronger than robots that can only do the most basic work with their programs.

Even with the evolution of life on earth, the human brain has been continuously expanded, and gradually become computers and supercomputers, forever above artificial intelligence and robots, and become the real masters of the earth.

It can be said that the current earth has ushered in the largest scientific and technological revolution of life genes after the industrial revolution, the information revolution, the earth's escape from the scientific and technological revolution, and the plundering scientific and technological revolution.

In this revolution in genetic science and technology, human beings have truly elevated themselves from ordinary higher animals to even higher beings, and may even dominate the entire Ossi Star Domain and even the entire universe in the future.
