Xu Xin was discussing something with Ji Chaoyang under the World Tree at this time.

He met Ji Chaoyang on the way back, and neither of them returned to the tree house. While observing the situation in the sky outside the city, they discussed what they should do next.

Although the Crystal City was still brightly illuminated by crystal white light at this time, the sky outside the city had completely darkened. The stars that were originally all over the sky looked extremely dim against the bright crystal white light, and not many of them could be seen.

"I went to see those mutant creatures outside Crystal City. There are indeed a lot of them, but... the level can only be said to be average." Ji Chaoyang was not very satisfied with the strength of the mutant creatures outside, and said with some helplessness, "

Judging from their current capabilities, the negative impact they have brought to our Crystal City may far outweigh the positive impact."

Do the negative impacts far outweigh the positive ones?

Xu Xin could understand Ji Chaoyang's point of view.

Although the number of intermediate mutant creatures in this beast wave has indeed increased,... they are basically just mutant creatures that have just been promoted to the intermediate level.

In fact, it is normal to think about it. They are just the first wave of beasts to besiege the World Tree. Naturally, the first wave of beasts cannot attack the king.

Thinking about it, the mission of these mutated creatures should be to test the effect of this strange crystal city. On this basis, it would be better if it can harm the World Tree.

They did not cause any harm to the World Tree, but perhaps their mission was accomplished.

Therefore, the individual strength of this batch of mutated creatures is naturally not very strong, but the number is very large.

What Crystal City captured was only a very small part of it.

Moreover, to be honest, the giant beast blood of these mutated creatures is not very strong. It is just the normal concentration of beasts in this world. It is basically not as concentrated as the Silver King ***, and may not even be as strong as Ah Fu.

Judging from their strength, if they were to form the first line of defense outside Crystal City, I'm afraid the results would not be very good.

After all, whatever they can defend against, Crystal City can basically defend directly.

Crystal City cannot stop attacks by beasts with only mutated bloodline, such as the pterosaurs from before, or attacks by high-tech weapons...

In the face of these, can they really play any role?

Feeling very suspended...

"This is indeed what I think." Ji Chaoyang sighed, "Their role always feels like the icing on the cake, but I'm afraid they will cause us a lot of trouble if they stay here."

As he said that, he looked at the outside: "I just took one of my survivors to the outside. There are some mutated creatures that have woken up in the outside, but..."

Xu Xin's eyelids twitched: "You mean...they are not friendly to survivors?"

"Yes, and no." Ji Chaoyang pointed to himself, "They are very friendly to me, and would even intentionally come up to me to show their kindness, but towards the person I brought, they showed a sense of strangeness and hostility."

...This is actually the case!

"This is a big problem." Xu Xin frowned.

At that time, there were Lou Fei'er, Jin Yue, Wen Guixin, and Coco beside him. None of the affected mutated creatures showed any hostility, and their inner monologues were all friendly.

This situation made him directly assume that these mutated creatures who were affected by the image of Crystal City would be friendly to them, the survivors.

Or maybe it will be friendly to the survivors who transplanted the tree house into the Crystal City.

But judging from what Ji Chaoyang said...

"It is indeed a big problem." Ji Chaoyang said in a deep voice, "We will use this place as our base in the future. If there is a chance, more survivors will move in here in the future, so the safety of the mutant creatures outside must be ensured.

Guaranteed."

"But now it seems that although they have not taken action, they are not close to each other. They may not pose a threat to the survivors now, but what about in the future? If the resources in the surrounding jungle are not enough to keep this group of mutant creatures

Let’s fill our bellies…”

Xu Xin nodded slowly: "Maybe they won't attack us, but the safety of others is in danger..."

"This is just one of them." Ji Chaoyang stretched out a second finger and said, "There is also a second point. These affected mutated creatures are not just the large beasts you see."

As he spoke, he pointed to the west of Crystal City: "The crystal house over there... is crawling with small mutated creatures. Of course, small means smaller than the ones you see, for example... like

Rats as big as cats are crawling all over the house. Oh, and there are also some insects."

this……

Thinking about it makes me feel a little sick...

"Most survivors still cannot accept this kind of existence."

"What do you think we should do?" Xu Xin rubbed his head in distress.

Rats and other things can be overcome, but the problem of hostility is indeed a big problem...

Ji Chaoyang was silent for a moment and shook his head: "I don't have a good idea."

He looked up at the World Tree. The height of the World Tree was still rising slowly, but the fastest growing thing at this time was its crown.

The dense tree crown is still extending to the surroundings at a speed visible to the naked eye.

Countless thigh-thick roots hang down from the tree crown, and some have fallen to the ground, slightly blocking the view.

Fortunately, the distance between these roots is relatively large and will not affect normal movement. It is like a street light on the road. Although the roots are there, normal people will not think that the street light is an obstacle.

These green roots are even more green against the white light, making the surrounding area as beautiful as a fairyland.

At this time, there were already many survivors wandering around under the tree house.

Ji Chaoyang glanced at the survivors: "The World Tree has not fully grown yet, and its role is not yet clear. It is difficult to draw conclusions now, but I have a direction."

As he spoke, he touched his backpack and took out a bottle of medicine.

"This is... giant beast potion?"

It was the giant beast potion left for them in the crystal room.

A medicine that allows creatures to acquire the blood of giant beasts, or enhance the blood of existing giant beasts, while accelerating the growth of the body and quickly growing into giant beasts.

The number of this kind of medicine is much larger than that of [Gene Medicine], and the number is at least thousands.

"My idea is to select the stronger ones from these mutated creatures and let them take the giant beast potion to become real giant beasts and help us."

Ji Chaoyang shook the giant beast potion for oral administration in the potion bottle.

"As for the other mutated creatures... I haven't decided how to deal with them yet. I need to wait until the World Tree grows up before deciding. Maybe now, we should try to give one of the mutated creatures a potion to test the effect. But at least we can't

Keeping them in vain."

Xu Xin was thoughtful, and just about to say something, his watch suddenly vibrated.

He raised his hand and saw that it was Zeng Tao calling.

His eyes lit up: "It seems Shi Wanyun is awake."

The voice connection was connected, and sure enough, Zeng Tao's voice came over there: "Xu Xin, Shi Wanyun is awake, come here quickly!"

Ji Chaoyang was also attracted attention.

Xu Xin had told him about Shi Wanyun's situation before, so he naturally knew what the situation was like now.

"How is she doing now?" Xu Xin asked.

"She's in good condition, with a smile on her face. But she didn't say anything when I asked her. She just waited for you to come back. I really..." Zeng Tao's voice was very dissatisfied.

"Okay, I understand, I'll go back right away."

After hanging up the phone, Xu Xin looked at Ji Chaoyang: "Do you want to come together?"

"No." Ji Chaoyang shook his head, "I haven't had much contact with her. My presence may have an impact. It's better for you to go alone and be careful. I also have something to be busy with."

"good."

Xu Xin quickly arrived at Zeng Tao's tree house.

Then he discovered that he could no longer control the roots of Zeng Tao's tree house.

That's true

It surprised him.

But...it's true.

Now Zeng Tao's tree house should be regarded as...parasitic on the World Tree?

Don't tell me, maybe his tree house is parasitic on the World Tree, but it just retains the core of the tree house.

"ever……"

Before he could speak, the roots of the tree house suddenly hung down, and then he was pulled up.

Zeng Tao walked up to Xu Xin in two steps, raised her head and smiled at him, "Haha, you can't just enter my tree house now. It feels much safer here immediately!"

Xu Xin glanced at her: "Are you not safe yet?"

In every aspect, she is safe.

Zeng Tao looked down at himself, then thought of something, suddenly raised his head and said angrily: "What do you mean, you..."

As a result, Xu Xin had already bypassed her and walked to the bed.

There was a yawning cat lying there beside the bed.

Shi Wanyun, who was originally lying on the bed in a coma, had already sat up from the bed and tidied up his somewhat messy hair.

Her skin is much fairer and smoother than before, and her face is much rosier.
