So what should we do now?" Li Wenxi looked around and saw a completely dark empty room, "Can't we get out for the time being?"

"How is it possible? Come with me."

Xu Ying took Li Wenxi's wrist, ran forward a few steps, and then...

Before Li Wenxi could react, she felt that the scenery in front of her suddenly became distorted, and then there was the familiar feeling of the world spinning and falling rapidly.

Then, a familiar scene appeared in front of her.

She returned to her previous villa.

"Is this... teleportation?" Li Wenxi was a little surprised, but not particularly surprised. "Is there a teleportation point under that statue?"

In her opinion, Xu Xin can also teleport. Xu Xin's sister Xu Ying, who was a survivor of the previous generation, can also teleport. This is relatively normal.

"Teleport point? Hmm... you can understand it that way." Xu Ying sat down on the sofa in the living room on the first floor and collapsed on it, "Oh, although going out this time is a bit dangerous, it made me confirm some things.

.”

"So?" Li Wenxi sat next to her and looked at her with some dissatisfaction, "You understand, I am even more confused! Please explain to me, what is going on?"

"Well... this started from a thousand years ago, ah, no, it should have been seven hundred years ago..."

…

Now that we have decided to let Shi Wanyun inject the medicine, it would be best to leave as soon as possible.

But before that, he had to make sure of one thing.

He asked Ah Fu to fly a certain distance into the air to verify how much mutant creatures Crystal City could affect.

Soon Afu flew back and forth, and the reply it brought was that by the time it reached an altitude of about fifty meters, it could hardly feel the influence of Crystal City.

Fifty meters?...

This height really makes Xu Xin a little worried.

If those flying mutated creatures were like this, then they would be in trouble.

However, in Afu's immature heart, a piece of information gave him some ideas.

As we all know, bats have very poor vision. They hardly use their eyes to determine the surrounding things, which is basically equivalent to being blind. They mostly rely on the echo of ultrasonic waves to determine the distance of obstacles or prey.

As a mutated creature, Afu's eyesight has been greatly improved compared to ordinary bats, but even so, it will be indistinguishable between humans and animals if it exceeds ten meters, and it will be completely indistinguishable if it exceeds twenty meters.

The general meaning of Ah Fu is that when its eyes cannot observe the crystal white light emitted by Crystal City, the influence of Crystal City on it will directly drop off a cliff. This distance is about twenty meters, and then it continues

When it rises to about fifty meters, the impact will disappear completely.

If considered from this aspect, Crystal City's influence will probably be greatly enhanced.

Most of the creatures in this world that can fly in the air are birds.

Compared with mammals like Afu who live in the dark, the eyesight of birds is not that simple. Even compared to humans, the visual distance of most birds can be completely overwhelmed.

After all, if a raptor flying in the air wants to hunt, it cannot do so without excellent eyesight.

This is the result of natural selection.

Therefore, if the indicator that the mutated creatures in the sky above Crystal City are affected is whether they can see the bright white light, then they basically don't need to worry about the flying mutated creatures.

There's no way they could survive.

Xu Xin directly posted the news in the explorer group.

Wang Lei: "If this is really the case, that would be so cool!"

Zhao Xiaochuan: "Can we just stand in the Crystal City and wait to catch the fallen bird?"

Qi Xuefei: "I'm not sure yet."

Ji Chaoyang: "Well, we still need to consider the worst case scenario."

Qin Yunlong: "The worst

The situation is that a group of flying mutant creatures will come, and the mutant creatures will not be affected by Crystal City, and will not fall to the ground, attacking the World Tree in groups? But in that case... we seem to do it too

It’s nothing.”

Xu Xin was also slightly worried.

The number of the first batch of mutated creatures on land is completely immeasurable. If the same is true for the flying mutated creatures and they are not affected, they will be in a very passive situation.

The flexibility of flying mutant creatures is much higher than that of ordinary mutant creatures. Even with the use of crossbow arrows that can attack from a distance, it is impossible to eliminate all flying mutant creatures.

Moreover, now that Li Wenxi is away, their resources are also very short, and they simply cannot afford the large-scale use of weapons.

At that time, the only method that can be used is probably...

Wen Guixin: "Have you forgotten me again? If that happens, what you need to consider is to find a way to get a flying creature, let me infect it, and then let it fly up

Just infect those mutated creatures."

This is indeed the only method Xu Xin can think of.

Zhao Xiaochuan: "Yes, let me go out now to see if there are any ordinary flying creatures around that I can catch."

The worst-case response method had been decided, and Xu Xin looked at the regional channels and alliance channels again.

So far, except for their side that has suffered from the beast tide, the other survivors in these two areas have not encountered any crisis.

This is the best thing.

"...When are we leaving?" Shi Wanyun, who was sitting on the side, became impatient and asked.

Zeng Tao paid no attention to the conversation Xu Xin had just had with the other explorers, and had been staring at Shi Wanyun intently to prevent her from suddenly escaping.

"Leave now."

Xu Xin looked out the window in the direction where Lou Fei'er and Coco were leaving, but there was no sign of anyone.

On the map, the green light spot representing Lou Fei'er was already outside the Crystal City, and was not moving much in the area.

It seemed that it would take some time for her to come back, so Xu Xin no longer waited for her, and was going to immediately take Shi Wanyun to the Crystal Room, which was only ten buildings away from the Crystal Palace, to inject her with medicine.

Of course, traveling with him were Zeng Tao, ***, and King Yin.

Zeng Tao was very cautious. The moment Shi Wanyun got out of bed, she immediately grabbed Shi Wanyun's wrist firmly to prevent her from running away.

"...You don't have to be so careful, there's no way I'm going to run away." Shi Wanyun frowned slightly, "Be gentle..."

"Huh, that's what you said just now! I won't be fooled again!"

"That was a special situation just now..."

After getting off the tree house, after just a few steps, they arrived in front of the crystal building.

Seeing the crystal building, Zeng Tao said with some sourness: "Huh, I haven't even injected the medicine yet, so I'm really taking advantage of you."

As she said this, she looked at Xu Xin eagerly: "I should have a share, right?"

"Of course." Xu Xin smiled helplessly, "When this crisis is over, I will inject you with medicine immediately."

"It's agreed!"

Xu Xin stretched out his hand and pushed towards the crystal door. Just like before, this crystal door that no one else could push open did not require him to use any force. It was as if his genes had been certified. The light shone slightly and then opened by itself.

Xu Xin immediately walked in, Zeng Tao dragged Shi Wanyun in and walked in, while *** lay down at the door and guarded the door.

There were four ordinary survivors around this crystal building. Seeing the actions of Xu Xin and the others, they all looked over here with some curiosity.

"Did you see that?"

"I thought I saw Brother Xin walking into that room with two girls?"

"Holy shit, Brother Xin really knows how to enjoy doing that kind of thing in the crystal room..."

"Ah, Brother Xin is actually such a person... Then do I also have a chance?"

Several people are getting closer and closer, wanting to live together

Come find out and satisfy your curiosity.

The *** who was guarding the door suddenly stood up, opened his mouth and roared at several people!

"Wow, it's Brother Xin's cheetah***!"

"For such a big person, the voice is really cute!"

"Don't look at the cute voice, I'll slap your head off!"

"It doesn't seem to let us get close..."

"Isn't that nonsense! Do you let people get close to you when you do that kind of thing?"

"Then we'd better leave quickly, but does this count as getting exclusive information?"

"Go, go! I want to tell everyone about this anonymously!"

Xu Xin in the room heard the noise outside, but without hearing enhancement, he didn't hear it clearly.

He was already holding a small bottle of medicine and standing next to the injection device, while Zeng Tao had already grabbed Shi Wanyun's arm and inserted it into the injection device.

Shi Wanyun showed no resistance at all, and there was even a faint light in his eyes.
