Just when Aoki put all kinds of creatures into the World Tree to evolve, Aoki on the Flying Cloud Star had already come to the side of the Elven Tree Qingyun, ready to help the Elven Tree advance.

Originally, it took several processes to advance the World Tree.

The initial growth of the World Tree releases the vitality, absorbs the vitality and then feeds back the vitality, and then activates the heart of the planet, and finally allows the World Tree to complete the process of advancement.

In this process, the vitality of a planet is the biggest driving force for the evolution of the World Tree, and it is also the key to the advancement of the World Tree.

It is actually a long time from the beginning of the growth and release of vitality from a world tree, to the absorption of vitality and then the return of vitality. Some World Trees consume millions of years, or even longer, just for that time period.

If it weren't for the fact that there was enough life on Earth, Aoki would have spent a lot of energy here.

Normally, the Elven Tree also needs to go through this time period like other World Trees. But now for the Elven Tree, time is limited, and many things are not up to Qingyun to consider.

However, nothing is absolute, but fortunately, Aoki brought back the primordial heart to the Elven Tree from the primordial planet. In the primordial heart, there is a lot of vitality that was bred by the elven world in order to cultivate the elven tree.

Although the number of these vitality is not large, it is enough to throw the Elven Tree to complete the long process of advancing from the zero order to the first order, and from then on, the elven tree has a certain ability to protect itself, and can even give birth to more elves.

However, the release of vitality in the primordial heart is not an easy task. If such a thing is said in the past, as long as there is the help and careful care of the Elven Tree Ancestral Tree, an Elven Tree can completely advance from the zero order to the first order. It's just that now the ancestral tree of the Elven Tree is not there, and I can only rely on Aoki, the daddy, to complete this work.

In the same way that the Elven Tree absorbs the Primordial Heart, Aoki requires the help of some energy ores and rare crystals to complete the process. In this process, Aoki consumes a lot of energy.

"Qingyun, are you ready?" After Aoki had prepared all the resources, he said to Aoi.

Looking at these resources placed in front of the Elven Tree, Qingyun took a deep breath, nodded and said, "Father, I'm ready." ”

Now after this period of growth and comprehension of the primordial heart, Qingyun's appearance is getting closer and closer to the elf. If you don't look closely, Qingyun looks like a goddess with the beautiful appearance of a medical elf, as well as elegance and beauty. It's just that this body is still a little illusory, and it doesn't really exist.

Hearing Qingyun's words, Aoki nodded, and began to count the crystals placed in front of the Elven Tree one by one.

These crystals contain many types, but the number is not very large, most of them are between one meal and two tons. Among them, the largest number is the Life Crystal, which is about four tons.

As long as the Elven Tree is advanced, it can completely absorb these life crystals, which is of great help to the growth of the Elven Tree.

"Now I can help you unleash the life stored in the primordial heart. During this process, you will feel the feeling of your heart being cut open. In the process, your spirit will be greatly traumatized. If you can't hold on, tell me and give up on this advancement. ”

"After all, there are opportunities to advance, but once your spiritual source is injured, it will have an unpredictable impact on future advancement. This kind of advancement is simply more than worth the loss for you. You know? Aoki showed a fatherly smile, which made Qingyun, who was originally a little nervous, feel much more relaxed.

Qingyun didn't say anything, but nodded solemnly. Soon, Qingyun disappeared in front of Aoki, entered the trunk of the World Tree, and merged into the primordial heart.

Now Aoki is preparing to help Qingyun advance, the most important thing is to allow the World Tree to completely absorb the vitality extracted from the primordial heart, and inject these vitality into the heart of the Flying Cloud Star Planet.

In fact, in this process, there are two most difficult points. The first point is Qingyun's own pain. When Aoki first integrated the primordial heart into the Elven Tree, the primordial heart was completely combined with the spiritual source of the Elven Tree and became the Elven Heart, that is, the heart of Qingyun.

Wanting to release vitality from the primordial heart is equivalent to cutting Qingyun's heart open and bleeding. Not to mention Qingyun, this kind of pain may not be able to withstand even Aoki himself. So when Qingyun decided to advance, Aoki's expression was also very hesitant.

But after all, this is Qingyun's own choice, and Aoki naturally doesn't have too many objections. What he can do now is to do his best to help Qingyun advance.

The second biggest difficulty in this process is to make the root system of the Elven Tree strong enough. Strong enough for the Elven Tree's roots to pierce into the heart of the planet and release life into it.

Flying clouds are different from Earth. Earth's planetary heart is a large magnet, while Flying Cloud's planetary heart is a giant snowball. The temperature at the center of this snowball reached minus 1 million degrees Celsius. This temperature can hardly be described by the theories of earth science in the past.

Almost all planetary hearts are beings that cannot be explained by ordinary science.

However, for these cases, Aoki also made precise calculations after obtaining the Primordial Heart. Although there will be many problems in the process of helping Qingyun advance, they can still be solved theoretically.

Aoki didn't want to let Aoyun suffer any harm because of his negligence, and regret it for the rest of his life. Therefore, in the process of Qingyun's advancement, Aoki also showed 100% strength.

Fortunately, since Aoki advanced to become a second-order World Tree, his sense of mind was more than ten times stronger than before, and his computing power for data had increased a lot. These are all the things that Aoki relies on for his self-confidence.

"Here we go!" When Aoki helped Qingyun advance, many elves in the trunk of the Elven Tree were also ready to advance and retreat with the Elven Tree.

Just as Aoki's words fell, Aoki's thoughts sliced open the trunk of the Elven Tree like a sharp scalpel, and thick green juice seeped out of it.

As the wound on the Elven Tree grew, the thick sap became thicker and thicker. Aoki then sent a life crystal that he had removed from impurities into the trunk of the Elven Tree.

At the same time, Aoki's mind turned into a round eggshell that encased the life crystal, chopping it into pieces and sending it deep into the trunk of the Elven Tree.

These chopped life crystals began to be digested in these green and viscous sap, and then turned into countless life gene energy to penetrate into the cells of the Elven Tree.

However, the process is very slow and even dangerous. It's like a person who eats poorly or has indigestion. What's more, the genetic energy contained in these life crystals is even more powerful.

Within the trunk of the Elven Tree, it was clear that these viscous green liquids could no longer meet the needs of these life crystals, and had even begun to experience a backlash of genetic energy. That's when Aoki needs to take action.

Aoki's method of making a move is simple.

The reason why the Elven Tree did not completely digest these life crystals did not mean that the Elven Tree could not digest the genetic energy, but that the Elven Tree itself, Qingyun, lacked computing power.

It's like a farm with tens of thousands of chickens and only one farmer. Even if there is more feed in the whole chicken farm, what can it be? The ability of the breeder is insufficient, and the daily work is too busy, and some chickens will become a burden to the breeder. If you don't get it right, it will tire the farmers to death.

It's the same with life energy.

Cells are like livestock being raised, and the energy of life is feed, and Qingyun is this breeder. Without Aoki's help, Qingyun, a farmer, would have been exhausted to death. But with Aoki, it seems that there is an automated breeding system in this farm, and the work of Qingyun, a breeder, will be greatly reduced.

With the coordination between Aoki's life crystal and Qingyun, more and more life gene energy is also absorbed by Qingyun...... (To be continued.) )
