This little pterosaur was very close to Xu Xin and was completely defenseless towards him. It closed its eyes and looked like it was enjoying Xu Xin's touch.

"It's so well-behaved!" Xu Ying's eyes lit up. She squatted down and reached out to touch it, but it turned its head away.

"Ah--" the little pterosaur flapped its wings and cried out, showing a little resistance to Xu Ying.

"...Why can you touch me but I can't?" Xu Ying and the little pterosaur stared at each other.

Xu Xin immediately activated his mind-reading ability.

【Don't touch me!】qqxsnew

[No one except the master can touch me! ]

The little pterosaur called him master.

"Little guy, are you the giant egg?" Xu Xin asked immediately.

"Ah!" The little pterosaur rubbed Xu Xin with its head.

Wow, it really is!

The dome had already shown signs of hatching during the previous hot summer activities.

Because he has not been here during this period, the task of hatching the giant egg has been given to the pangolin concubine, and the three pangolins are taken care of by Li Yajun, who has the knowledge and ability in this area.

He has been very busy recently and has not paid attention to the hatching progress of the dome.

And now, the giant egg that could move freely before it was hatched has actually hatched a living creature!

All in all, more than a month has passed inside the World Tree, so it is normal for the giant egg to hatch during this period of time.

But, this is a... pterosaur?

Xu Xin had seen petrified pterosaurs before, but there seemed to be something different about this little pterosaur before him...

Where... ?

"Ah, it's Brother Xin who's back! And is that... Brother Xin's sister?"

"Finally I see Brother Xin again. Has it been another half a month?"

"You can't say it's finally here. It's only been a few hours outside."

"Brother Xin! How's the home we built? Isn't it great?"

All the survivors had smiles on their faces that they had never seen before.

Everyone gathered around.

Before everyone gathered around, the little pterosaur had already taken off into the sky and flew to the orchard.

Xu Xin talked with the survivors who gathered around him.

During this period, they have been building this area and have hardly had any rest except sleeping and eating.

But each of them is very satisfied.

"Haha, Brother Xin, we're not tired at all. Compared to outside, we're just like playing a construction game!"

"Oh, I've had a dream since I was a kid, to build my own area just like in the game. I never thought it would come true in this world!"

"What world? This is Earth, okay? You should be saying that your dream has finally come true after a thousand years~"

"...? Why does it sound so miserable? Besides, I'm talking about the world within this 'World Tree'!"

Amidst the laughter and joy of the crowd, Xu Xin asked about the current location of Ji Chaoyang and the others, then said goodbye to everyone and walked over there.

Infected by this atmosphere, Xu Xin sighed, "Oh, they are living so comfortably here. I don't even want to go out."

"Hmm...me too." Xu Ying said with some envy, "After we transfer the technology from the underground world up here, we'll need some time to produce weapons and equipment. It's perfect, I can also live a relaxed life here for a while."

If this area was like a township before, it now looks like a villa area.

"There's even a stream?" Xu Xin looked at the stream that ran through the area not far away, somewhat surprised. "How did this stream appear? Where does the water come from?"

This reminded him of the memory that Shi Wanyun had passed on to him. There was also a stream in the area where the woman called No. 5 lived.

"Don't forget, this is inside the World Tree. If you want water,

It’s so easy.”

The two walked to the stream. Xu Ying scooped up a handful of water and took a sip, revealing a satisfied expression: "As expected, it's the water from the World Tree. It's so sweet!"

"The spring water from the World Tree?"

Xu Xin looked towards the stream and saw that there were even some small fish and shrimps swimming in the flowing stream.

"Yes, it's water drawn from the World Tree, purified by the World Tree, and then provided to those within it."

Xu Ying stood up.

"This is also one of the unique abilities of the World Tree. It purifies water resources. Even by the sea, in a place full of poison, or even in the desert, as long as you plant a World Tree, it will be able to extract sufficient water. Moreover, all of it is very high-quality World Tree spring water that can be directly drunk."

She explained.

"...The World Tree is indeed researched by alien invaders, it is extremely strategic." Xu Xin sighed.

This function alone would have been a national treasure a thousand years ago.

"No, that's not something those monsters deliberately studied." Xu Ying shook her head. "Water is the source of life on Earth, but not for those alien invaders. As far as I know, they don't need water at all.

The World Tree can purify water resources probably because the World Tree's prototype, the Banyan Tree, itself needs to absorb a lot of water. We can just get a piece of the pie..."

"Wait a minute," Xu interrupted her. "You just said that alien invaders don't need water to survive?"

"As far as I know, they don't need it." Xu Ying nodded. "Not only do they not need it, they seem to have a strong aversion to water and don't even want to come into contact with liquid water."

"Is this really the case..." Xu Xin said to himself.

"Um...it was just a rumor we had at the time. Whether it was true or not, I don't know. It was a rumor we couldn't confirm, but that's what everyone said at the time."
