The Taiyin Human Emperor and the Sun Saint Emperor soon left the Divine Realm with Zhou Tong's scriptures. They both returned to the Ziwei Star Realm, which was their hometown.

"You really don't want to go to the fairyland to see it?" Yan Ruyu asked after the two holy emperors left.

"Of course I will go to the fairyland to see it, but this world still needs to be taken care of." Zhou Tong shook his head and said, "Some things must be arranged to prevent any changes in this world in the future."

In the original work, Ye Fan basically abandoned this world.

Whether it is Ye Fan, the ruthless emperor or the ruthless emperor, they have not had enough time to study the method of immortality. They all took the Immortal Medicine for a lifetime.

When Ye Fan went to the Immortal Realm, he took away all the immortal medicines in the whole world, which directly reduced most of the time when the emperors in later generations studied the method of immortality and moved to the Immortal of the World.

Originally, the road to the Immortals in the World was a limit of long jump in every life, and Ye Fan and the others even pulled away one of the pedals. It can be said that this change almost made it impossible for people like them to appear again in later generations.

After he left this world, he never came back, so this led to the fact that the world in later generations completely became the test ground for an unknown immortal emperor, and was constantly reincarnated.

Zhou Tong doesn't want such a thing to happen in the future, so he needs to make some arrangements.

Although once the unknown immortal emperor takes action, Taiyin and Sun will definitely not be able to stop it, the stronger the world, even the immortal emperor will definitely consume more power, making it more difficult to complete this arrangement of reincarnation quietly.

"However, there is still one thing missing from the real growth of this world, that is the World Tree!" Zhou Tong glanced at the world tree inside his Ten Cave Heavenly Divine Ring.

It is difficult to cultivate the world tree. The world tree in Zhou Tong's hand is also much easier to cultivate because it was originally degenerated from the world tree; but the real world tree often needs to grow naturally and transform it bit by bit.

In addition to the natural transformation, if you want to re-cultivate a world tree, the easiest way is to find a real world tree, and then use this tree as a guide to cultivate a child bit by bit; in fact, the so-called Hedao Immortal Seedlings of World Tree Seedlings are cultivated in this way.

Because this cultivation method involves the most fundamental world tree in this world, even at the peak of the Immortal Realm, the seedlings of the World Tree are the top Hedao seeds. It is impossible for people without a large background to obtain them.

In fact, this is how the world tree of the ten crowns of the ancient times was cultivated. In the ancient times, the immortal kings of the nine heavens and ten earths were led by the world tree in their own world as the guide, and nurtured a seedling of the world tree, and were finally obtained by the ten crowns of the king.

Zhou Tong is doing this now. He is now cultivating a world tree's child by secret method. However, the world tree he cultivates is not a species of Hedao Immortal seed, nor is it a species of weapons and magic weapons for people, but a world tree for the outside world.

It can be seen that a seed has begun to be nurtured in the world tree. This seed is absorbing some of the rules of the world tree and growing slowly.

"If I'm not doing it wrong, this seed will take at least tens of thousands of years, or even twenty-hundreds of thousands of years, to be truly cultivated and formed." Zhou Tong said in his heart, "But I don't lack time now, I can afford to wait."

It takes more than ten or twenty-thousand years to cultivate a world tree seedling. You can imagine how precious this thing is. Moreover, the world tree cannot be continuously cultivated. After a child is cultivated from the body of the world tree, the body of the world tree needs to be cultivated for at least a million years before it can be cultivated again, otherwise the world tree will be damaged.

"I don't know what the world tree was born in the inner world of Qing Emperor. Could it be a lotus?" Zhou Tong said silently in his heart.

At the same time, he looked at the prince.

As a test subject for the new experimental system, Emperor Tian also has a quasi-world tree in his body, but Emperor Tian is still too weak now, and that world tree will maintain the word "quasi-" for a long time.

"Actually, it's not impossible to make Prince Tian the second immortal king?" Suddenly, a thought emerged in Zhou Tong's mind. Perhaps there is a way to make Prince Tian the Immortal King directly in a short period of time?

Although Prince Tian is a test piece, he is also an existence who has survived the Creation Tribulation. Moreover, the Creation Tribulation he has survived is second only to Zhou Tong, and is even stronger than the Qing Emperor's Tribulation. In addition, there is a quasi-world tree in his body.

Such good conditions, if you push him a little behind the scenes, you might really succeed.

"However, as for how to push him, it needs to be finalized." Zhou Tong did not think about how to push him for a while.

The easiest way is actually just like Emperor Huangtian completed the nine heavens and ten earths back then, killing a group of true immortals or quasi-immortal kings, and directly using their avenue and origin to repair the world.

However, although the inner world of Prince Tian is perfect, the origin is not that strong, so there are probably many true immortals or quasi-immortal kings that need to be killed.

Moreover, this method also has a disadvantage, that is, the world tree cultivated by killing. If there are more than one, you may enter the devil's path. This is not the right way.

"However, the cultivation matter still needs to be discussed slowly. I'd better get the Hedaohua first!" After pondering for a while, Zhou Tong made up his mind.

In any case, if you want to integrate the World Tree into this world, it is the easiest way to directly lead the Hedao Flower. Although the seedlings of the World Tree have not yet been formed, it is not wrong to hold the Hedao Flower in your hand first.

Zhou Tong swept his huge spiritual sense and soon noticed the existence of the Jiulong Coffin. He then moved his expression, crossed the endless star field, and descended on a deserted planet.

Here, there is a five-color altar, and next to the altar are nine huge black dragon bodies lying.

It takes energy to pull the coffin to set off, and if this desolate planet wants to accumulate enough energy for its action, the time unit is probably ten thousand years.

The ancient coffin is simple, I don’t know how many years have passed.

Zhou Tong came to the coffin, sat quietly cross-legged on the coffin, listening carefully to the sound of scriptures in the coffin, and a strange color appeared on his face.

Zhou Tong had thought he had thoroughly understood the hundreds of words of scriptures, but now he listened again at the realm of the Immortal King, and suddenly felt a different feeling.

This scripture, on the surface, talks about the construction and deduction of the fairyland, but now after careful deduction, he suddenly discovered that there are deeper mysteries in it.

"Is this kind of mystery... reincarnation?" Zhou Tong pondered for a while, and felt a little vaguely in his heart, but he felt that it was not right, not a complete mystery.

"If the scriptures left by Emperor Huangtian became the Immortal Emperor, if you want to understand the deeper stage, you may only be able to become a quasi-Immortal Emperor." After sitting cross-legged for three years, Zhou Tong finally shook his head. Being able to comprehend a trace of the mystery of "reincarnation" was considered to be his destiny, but it was impossible to comprehend more things.

"If you don't have enough strength, nothing is useless!" Zhou Tong finally gave up comprehending these things and directly opened the innermost bronze hall. Suddenly, the chaos and the immortal light was everywhere.

The innermost part is a vast world, with fairy light flowing and sufficient biomass, which can be called a small fairyland.

However, Zhou Tong didn't care much about this world, because in terms of quality, this world is not as good as his Ten Cave Heavenly Divine Ring World. What he cares about is the Hedao Flower among them.
