"How long?" Zeng Tao asked curiously.

"It doesn't matter how long." Ji Chaoyang looked at the tube of potion on the table, "As long as the World Tree withers, the people living in the World Tree must be exposed to the sun."

Yes. That's the most important thing.

Even if it just destroys the World Tree and then grows it back again, it won't work.

"Then... why didn't they do this before?" Zhao Xiaochuan asked.

"Because this kind of potion is not so easy to make." Xu Ying explained, "The potion in front of us needs to be concentrated hundreds of times, and at least hundreds of liters are needed to be injected into the trunk of the World Tree in a short time. The potency of this potion is

The speed of destruction can be faster than the self-healing speed of the World Tree, causing the World Tree to wither quickly."

"Concentrated medicine cannot be stored for a long time because of its unstable nature." Xu Xin took over the words and continued, "Although the alien invaders invented this medicine before, they had no enemies, not even imaginary enemies.

, naturally you won’t have such an unstable substance in your hands.”

"Moreover, this substance is actually extracted from scarlet crystal. If you want to make it, it will consume their source of life. Naturally, they will not do more experiments."

"Oh... the substances in the scarlet crystal will inhibit the destruction of the World Tree with the white crystal as its core, right?" Qin Fu said to himself.

"In short, they already have the ability to destroy the World Tree and threaten our survival." Xu Xin tapped the table with his finger and said, "Although they have no intention of attacking us yet, they still need to remain highly vigilant.

.”

"Are you afraid that they will sneak over and give our World Tree an injection? That's impossible, at least we will definitely find out in advance." Lou Fei'er was very confident in the World Tree, and raised her eyebrows and said,

"Don't forget the special features of our World Tree."

The special thing about the World Tree is that the internal time flows a hundred times faster.

Observing the outside world from the internal console, everything outside seems to be at a standstill.

In this case, it is easy to observe the changes in the outside world. It is basically impossible for the other party to send people to secretly approach the World Tree and harm the World Tree.

"If a missile with a needle is fired from the opposite side, it will directly penetrate into the World Tree with a 'click', and then inject the internal medicine into the World Tree..." Qin Yunlong put forward a somewhat exaggerated idea.

Although it is a bit exaggerated, it is not impossible.

"If this is true, don't worry, the anti-missile system has been installed outside." Xu Ying lay down beside her, on Li Wenxi's lap, and said, "The preliminary layout of the interior and exterior of our World Tree has been completed. But for the time being, it should be

There’s no need to worry, because the other side doesn’t seem to be paying attention to us yet.”

On the other side of the earth, in the vast land, there is a room full of Xiaoqiang.

Then let them crawl away?

Is this kind of thing worth traveling halfway across the planet to eliminate bugs?

Not worth it.

This should be what alien invaders think now.

"Do they really have no intention of attacking us?" Ji Chaoyang looked at Xu Xin, "Do you already know what happened to those petrified creatures outside? They are not sent by alien invaders."

"Well, no. They came with that monster."

Xu Xin nodded.

"ah?"

"Were those petrified creatures brought by that monster?"

Everyone in the explorers was a little surprised.

Then they all felt it was reasonable.

Ji Chaoyang nodded lightly: "Yes. The survivors, especially the survivors in Area 188, should be very concerned about it. After all, there are existences like us. The underground experiments in Area 188 should be caused by it."

That's right.

The giant beasts in the underground world are experiments conducted by alien invaders, making a large area of ​​the underground world full of such giant monsters.

But it is the monster who wants to control the underground giant beast through petrification.

"Did it do it?" Li Wenxi said in surprise, "Why did it...ah, in order to make its own power stronger?"

"Yes." Xu Xin nodded, "After all, it has not been completely accepted by the alien invaders. For its own sake, it wants to have its own power."

Now that I think about it, Chang Yin is unconscious, probably because he was controlled by it by some means.

"Then those groups of petrified creatures, including Changyin, are here..."

"It came to see us and take refuge with us." Xu Xin said, "Although it teleported here first, the petrified creatures are restricted by the World Tree and cannot teleport directly to the World Tree. They can only teleport to the closest location first and then walk over.

.”

"So that's it..."

Everyone present probably understood the current situation.

"Then what should we do next?" Wang Lei stood up and stretched his strong body, "I have been staying in the World Tree for a while, and my body is almost rusty! It's time to move.

It’s active!”

"Nothing to do for now. Let's continue what we did before." Ji Chaoyang said, looking at Xu Xin at the same time, "You should think so too."

"Yeah." Xu Xin nodded, "Right now, we don't even have the qualifications to show our strength to attract them. What we have to do now is to develop as quickly as possible. Before that, any plans to steal homes are meaningless. We at least have to

First we must protect our World Tree!"

Fortunately, there is plenty of time in the World Tree.

Just give them a few days of outside time, and they may be able to develop well internally!
Chapter completed!
