The Heart of the Flying Clouds is not only different from the hearts of other planets, but also very different from the hearts of the earth, just like one in the sky and one on the ground.

Between the hearts of the planets, it is as if some of the planets are a stone, some of the planets are a small sun, some of the planets are a mass of sticky creatures, and so on. But more of the Heart of the Planet is just a giant nuclear reactor and doesn't have much of a peculiarity.

The Flying Cloud Heart of the Flying Cloud Star is even more special than the Earth Heart of the Earth.

The Heart of the Flying Clouds is a large mass of ice whose temperature is so low that it surpasses Aoki's cognition. This ice mass is one-tenth the size of the moon. Endless cold air was brewing inside, and even more and more ice and snow spirits were forming on it.

It's just that these ice and snow spirits are just ordinary creatures, not only do they have no body structure, but even their instincts have not been derived. However, there was information about this on the Golden Ring, and Aoki knew a little bit about it.

This planetary heart is called the Collapsed Heart. The collapse of the heart evolves to the extreme, and it is a black hole. It's just that compared to black holes, the collapsed heart can only absorb heat, while black holes not only absorb heat, but almost all matter can be absorbed by black holes. This is the most essential difference between a collapsed heart and a black hole.

The Collapsed Heart is the most sensitive to temperature, and it can be said that objects above minus 10,000 degrees Celsius will be sucked away by the Collapsed Heart. These objects eventually disappear into debris in the core area of the Flying Cloud Planet.

Of course, the minus 1 million degrees Celsius mentioned earlier refers to the core temperature of the collapsed heart. The average temperature of the outer layer of the Heart of the Clouds is about -10,000 degrees Celsius.

Such a low temperature will definitely implicate the creatures on the Flying Cloud Star Planet if there are no measures to protect it, and even turn the entire planet into a huge cold storage, which is not suitable for any life to survive. However, since this situation did not happen, it means that there is some special substance in the collapsed heart.

It is precisely because of the action of this special substance that the collapsed heart forms a powerful attraction and keeps the super low temperature area within a certain range, so that after hundreds of millions of years of metamorphosis, there is gradually some life on Feiyun Star.

Aoki's previous worries were more about the fear that the root system of the Elven Tree would not be able to get close to the Heart of the Flying Clouds and would be directly shattered by the super low temperature. In the end, it also hurt the Elven Tree and hurt Qingyun. This is also the reason why Aoki is hesitant to advance to the Elven Tree.

However, in the process of the growth of the Elven Tree's root system and getting closer to the Heart of the Flying Clouds, Aoki's doubts were gradually dispelled, and even turned into surprises.

Because he saw that when the root system of the Elven Tree continued to enter the Heart of the Flying Clouds, there was a qualitative change, and a cloud of green liquid actually flowed out of the root system of the Elf Tree, protecting the root system of the Elven Tree like armor.

The protection of the Elven Tree's root system is a little different from Aoki's own protection.

In order to prevent the erosion of the sense of thought by low temperatures, Aoki uses a reflection cancellation method. It's like a palm fight between martial arts masters, and Aoki also uses the same way to absorb the heat of the Heart of the Flying Clouds, so that the two forces are comparable, and Aoki's sense of thought will not be destroyed by the super low temperature environment of the Heart of the Flying Clouds.

The roots of the Elven Tree formed a layer of green armor as it gradually penetrated into the Heart of the Clouds. This green armor has no effect on conduction at any temperature, acting as a super-temperature insulator.

In this way, even if the root system of the Elven Tree penetrates into the Heart of the Flying Cloud Star, it will not be damaged by the super low temperature of the Heart of the Flying Star Planet.

This should be the talent of the World Tree of this planet.

Soon, drops of green liquid dripped from the Elven Tree's roots. Not only did the green liquid fall on the Heart of the Planet not to be frozen, but like drops of extremely corrosive sulfuric acid, the Heart of the Flying Cloud Star burned out of a passage, allowing the roots of the Elven Tree to continue to penetrate into it, and finally completing the communication between the Elven Tree and the Heart of the Week.

Later, with the liberation of the Primordial Heart, a large amount of vitality was also integrated from the Primordial Heart into the Flying Cloud Heart.

As more and more life is integrated, a certain part of the Heart of the Flying Clouds begins to change. After that, I saw a door slowly open, this is a dimensional door, leading to the dimensional space where a large amount of materials is stored.

As this door was opened, a large amount of life breath, energy ore, and various rare crystals were also released.

Immediately afterwards, the body of the Elven Tree began to change continuously, from less than 10,000 meters to 40,000 meters before it stopped. Not only that, but the diameter of the Elven Tree has also grown to nearly a kilometer.

If the previous Elf Tree was a weak little girl, then the current Elf Tree is simply a heroine among women and a heroine.

If it weren't for the particularity of the Golden Ring and the Earth, in front of the Elven Tree, I'm afraid even Aoki would have to admit that he was not as powerful as the Elven Tree when he first advanced to become the First-Order World Tree.

However, the infinite expansion of the body of the Elven Tree alone is not enough to make it manifest, the key is what benefits the origin of the Elven Tree has obtained.

It is said that the Elven Tree is the source of life, which can give birth to countless living objects, and even has a healing and restoring effect on the creatures of countless civilizations. Therefore, when the Heart of the Flying Clouds is activated, the first thing that a large amount of life breath is restored is the spiritual source of the Elven Tree.

Originally, because of the damage to the primordial heart, Qingyun's spirit had been reduced to the size of a motorcycle, and after receiving a large amount of life breath, Qingyun's spiritual origin also began to be gradually restored. Soon, Qingyun's spiritual origin grew to ten times the size of before, and it was even more condensed than before, and even many powerful abilities were generated in Qingyun's body.

Of course, if Aoki doesn't have a golden ring, and Qingyun doesn't have a primordial heart, these instincts will take a long time to comprehend. However, under the influence of the primordial heart, it will probably take less than a year for Qingyun to fully master these abilities, which is what makes Aoki excited.

After the change in the body of the Elven Tree, the entire Flying Cloud Star also began to undergo earth-shaking changes.

Originally, the two continents on the Feiyun Star, with the advancement of the Feiyun Star, the two continents began to divide constantly, and finally became six continents, and even some islands were formed around these continents, which has a feeling of ancient earth.

It turns out that the World Tree also existed in the age of dinosaurs on Earth. At that time, the earth was originally just a continent. Later, with the advancement of the World Tree, this continent was gradually divided into five continents and four oceans at that time. The changes on the Flying Cloud Star now seem to be restoring the situation when the Earth was originally advanced to the World Tree.

After the continuous expansion of the Flying Cloud Star, in about a month, the volume of the Flying Cloud Star increased by more than three times, and the weight increased by almost five times.

These are nothing, after the feedback of the heart of the flying clouds, the elf tree continues to grow, and finally after a month of growth, the elf tree has grown to a height of almost 100,000 meters, and the radius has reached thousands of meters before it stops growing.

Countless branches and leaves also stretched out from the Elven Tree. The elves who lived in the Elven Tree had also benefited a lot, and even the Celestial Star and the Nine Star had reached the edge of advancement that could advance to the sixth-order behemoth.

Some other elves have also advanced, a large number of elves continue to grow in the elven tree, and even some new elven embryos have begun to brew in the elven tree.

If this development continues, it won't be long before Feiyun Star will become an elven planet.

After the advancement of the Elven Tree, Qingyun's form was slowly recondensed and became a new individual.

If Qingyun was said before, she seemed to be a slightly childish, but delicate-minded little girl, who was burdened with a huge mission, and seemed worried.

Then the current Qingyun is completely like an intellectual woman. Her expression was calm, with a hint of determination in her eyes. This confidence does not come from a mission, but from a sign of true inner strength...... (To be continued.) )
