After entering the royal city, the two quickly got up, preparing to deal with the attack that came later.

But to their surprise, no plants appeared in the royal city. And the plants outside the city just kept hitting the city gate. There is no sign of rushing in.

Yu Tu took a closer look and noticed a vague energy layer. It's like some kind of golden text.

Inside the royal city, all buildings have this kind of writing. If you look carefully, you can see that all the building surfaces are trembling irregularly.

The royal city is indeed covered by plants. But the royal city itself still has a kind of protection that restricts the movements of these plants. This gave Yu Tu a rare respite.

The two did not stay, and hurried to the tower.

As the two arrived, the plant's reaction became more intense. But the thin light layer of text is tightly bound.

The two rushed to the position of the tower unimpeded. The gate of the tower also has that golden text. Each text is the size of a palm.

At this time, Yu Tu understood the meaning of the text. It is an ancient **** language. That Saslow person, in the original Saslow, is definitely not low. This kind of large ancient **** language magic circle, even in Saslow, not many people can easily build it. Not to mention completing the construction of the magic circle by oneself.

After the two approached, the words on the door naturally fell off and disappeared. The gate of the tower opens automatically.

The layout of the first floor of the tower is simple. There are three tall bookcases inlaid on the wall. I don't know why, the books inside are completely rotten. Then there is a desk and a chair.

Only from the layout of the first floor, there is not much to be seen. Moreover, their purpose is not here.

After finding the stairs, the two began to climb the tower.

In the entire tower, there seems to be only one floor and the top floor. Yu Tu quickly rushed to the top.

The space on the top floor is much more spacious. Yu Tu's goal is the only room on this floor.

The door of the room was there, Yu Tu reached out and pressed on the handle, gently pushing the door open.

Standing outside, they couldn't see the scene in the room at all. It was pitch black, as if resisting light.

After the two entered the room, their vision instantly changed.

The faint candlelight illuminates the entire space. This room is far smaller than imagined.

The entire space is less than twenty square meters, and the height is just over two meters, which is very depressing.

In a small area, it is filled with a few things. There is a bookcase covering the walls on each side of the wall. The above book is not only well preserved, but also has a lot of magic flow.

A bed was placed directly opposite the door. A desk is placed at the foot of the bed. The body of a doll sits at the desk, looking down at the paper on the desk. On the ground, there is also a skeleton with luxurious clothes. Beside the bones is a pitch-black dagger, leaving only a hint of golden at the tip of the knife.

"What's the situation? Yu Tu, is that person still dead?"

Yu Tu shook her head and walked to the table. Although this Saslow was transformed into the immortal body of a puppet, Sasro's immortality was not just about being transformed.

Keeping alive for a long time is a punishment. Saslow’s troops take turns to rest to ensure the soldiers’ mental state. It must also be ensured that the management class will not fall into rigid thinking because only a group of people are in charge.

When the situation in Sasrow is stable, Yu Tu will choose to continue this way and let the soldiers rest well.

The soul of the person in front of him has completely disappeared due to long hours of work. It is impossible for him not to know this flaw. Judging from the situation of this underground kingdom, he can completely dormant himself to ensure his own existence.

It can only be said that he has reasons to be sober.

Yu Tu bowed to the doll, and then picked up the paper in the doll's hand.

There is a painting on it. It depicts a tree. This tree has a main trunk, after extending to a certain distance, it is divided into seven, and seven new trees are derived.

Yu Tu quickly noticed one of them. The trunk is straight, with large vines hanging from the canopy, and people hanging on it.

This tree was the one in Winslow's ruins at that time. For those vines, Yu Tu can be described as fresh in his memory, mainly because the monsters are too disgusting.

There is also a text description next to the tree.

"The tree of life pays a high price to gain the power of life. The power of the tree owner will be correspondingly improved with the number and quality of sacrifices. At the same time, the power of the tree owner will gradually increase over time. And, Will not be shackled by power."

Seeing this string of words, Yu Tu couldn't help feeling a chill in her back. If these words are true, it is indeed the tree where Winslow is recorded. Then, the power of Kazanla is unknown. Being able to survive at the beginning was really lucky.

It is estimated that Kazanla has just awakened, but his strength has not been fully recovered. In giving her some time, destiny cannot limit her.

Later, Yu Tuyou found this tree in the city. It is also highlighted.

"The tree of beasts combines immovability and movement. The summoned sacred tree that swallows life and transforms life into servants. The monsters made by the tree can be resurrected without limit as long as the tree is not destroyed. The owner of the tree will also have it. All the power of the servant. The tree will not be restricted by the owner. Even if the owner is killed, the tree can still move freely. But the tree without the protection of the owner is very fragile."

Beside this text, there is an annotation by the Saslovak himself.

The tree of beasts was unexpectedly discovered by him. Together with this drawing of the eternal tree. The tree seemed to have been badly damaged and degenerated into a seedling stage.

Compared with the power that this tree can bestow, what the Saslow people see is the trampling of life by these so-called **** trees. Of the seven trees, five need to sacrifice a lot of life.

For unknown reasons, the Saslovaks established a country near the tree. In other words, the magic circle has been built into a country to guard this magic tree.

In the seedling stage, the magic tree needs a lot of blood to irrigate or directly sacrifice to awaken its power. Only a fully grown tree can be destroyed.

But the destroyed tree will only return to its original juvenile stage, waiting for the next awakening.

No solution.

Yu Tu understands why such a dangerous thing will always be suppressed rather than completely destroyed. Because it can't be destroyed at all.

If you want to destroy the tree, you must sacrifice your life. Let the tree grow. But after the tree was destroyed, it just returned to its original juvenile stage. In this way, all efforts to destroy the tree become useless. It's better to keep him in the sapling state.

As for the method of complete destruction, Yu Tu didn't think he could easily think of things that the Saslovans could not accomplish after exhausting their lives.

The most important point is what the so-called tree of eternal life is.
