"knew!"

"Hmm!" Keke was not interested in anything in the house. She immediately jumped out of Lou Feier's arms and onto Xu Xin's shoulders.

Xu Xin rubbed Keke's little head, nodded to them, and then said to Shi Wanyun, "Let's go."

As he spoke, he summoned the Silver King from his bracelet.

The moment the Silver King came out, the hair on his body suddenly stretched out, and then he looked up to the sky and let out a long howl: "Awoo——"

Under the bright white light of the surrounding crystal buildings, its silver-gray fur looked more beautiful, and the blood patterns on its body seemed to have become a little lighter.

Is this what Yingying in the video said, strengthening the bloodline of the giant beast and suppressing the blood pattern mutation?

The Silver King's behemoth bloodline is relatively rich, so the effect is immediate.

"Come with me."

Xu Xin climbed onto the wolf, hesitated for a moment, and reached out his hand to Shi Wanyun, who was looking at the Silver King in surprise.

"Oh, okay." Shi Wanyun nodded slightly, grabbed his hand, and was pulled forward by him.

He didn't dare let this woman sit behind him.

"Silver King, full speed back to the treehouse!"

“Ouch—”

The Silver King howled again, then kicked his feet, and the whole wolf suddenly shot out, running wildly towards the tree house, shuttling back and forth between the crystal houses.

"ah!"

Shi Wanyun didn't react in time and her back suddenly bumped into Xu Xin's arms.

"Hmm?" Keke lowered her little head and patted Shi Wanyun's head with her little paws.

She subconsciously wanted to leave, but when she thought of her plan, her body paused and did not move.

However, Xu Xin didn't dare let her get so close to him, so he immediately pushed her away gently: "You should have a mount too, right?"

The mount is the reward for collecting the three treasure chests of gold, silver and bronze. Since Shi Wanyun has found the gold treasure chest, she should have a mount.

"Hmm...it was a very fast and large elk." Shi Wanyun was a little surprised when Xu Xin pushed her away, but she didn't say anything. "It should still be in my tree house now. I wonder what's going on with it."

Deer?

“Good choice.”

Normally, deer are faster than wolves and are much larger in size.

Although normal riding is definitely not stable, with the support of the mount contract, it is also a very good mount. It does not need to eat meat like the Silver King, but only needs to eat grass.

The Silver King was very fast. In less than a minute, he rushed from the center of the entire Crystal City, the location of the Crystal Palace, to the very edge of the Crystal City and rushed out of the Crystal City.

The distance was about two and a half kilometers and it took less than a minute.

The Silver King's speed increased again.

The moment they rushed out of the Crystal City, the two people on the wolf's back immediately felt that they were enveloped by even hotter air!

It was too hot, and Xu Xin was now tightly wrapped up, making it difficult for him to breathe.

Only then did he realize that the temperature in Crystal City was actually quite suitable!

Although the temperature rose rapidly from around 20 degrees Celsius to at least 40 degrees Celsius due to the influence of sunlight and the high temperature of the ground when it rose to the ground!

But after that, the temperature seemed to start to drop, and eventually stabilized at around 30 degrees.

Because he was a little anxious, he did not notice this matter. Lou Feier and the others did not notice it either because their mutated bloodlines had low temperature sensitivity.

Thirty degrees, although it is not a comfortable temperature, compared to the temperature outside Crystal City which is close to fifty degrees, it is simply the difference between heaven and hell!

It seems that Crystal City has the ability to control temperature!

That's right, since the Giant Core and the Tree House Core, which are made of very similar materials, can maintain temperature, it's normal that Crystal City can also control the temperature.

However, he also tried those two cores when the hot summer came. Although they could bring warmth in the cold winter, they could not bring coolness when the hot summer came. It should be because those two cores rely on releasing energy to maintain temperature. No matter how much energy is released, the high temperature is still high temperature.

But Crystal City can... does this count as absorbing heat?

If you ignore the fact that the buildings are glowing all day long, that place is really suitable for living.

The 500-meter distance between the edge of Crystal City and the tree house is just a dozen seconds for the Silver King.

As soon as he rushed out of the jungle, he immediately heard many people cheering.

"Brother Xin! Brother Xin is back!"

"Brother Xin is awesome!"

"That crystal-like city outside, was it really built by Brother Xin?"

"This is too strong!"

"Huh? Who's that woman sitting in front of Brother Xin? Why haven't I seen her before?"

"A new person you met by chance?"

"She's actually riding a wolf with Brother Xin! Why not me?"

"By the way, did any of you see that before Crystal City appeared, didn't a girl also come?"

"I saw her, and I felt that the girl looked familiar..."

"It seems like you're chatting with Wen Xi now?"

…

Xu Xin's arrival attracted the attention of a group of survivors who were leaning on the windows of the tree house and looking out.

They still lived comfortably on the first and second floors of the tree house.

"Xu Xin, come up quickly!" At this time, the window on the third floor opened and Li Yajun stuck her head out of the window.

Without saying a word, Xu Xin controlled the roots and quickly rolled him, Coco, the Silver King and Shi Wanyun up.
