"In short, all we can do in this regard is to improve ourselves as quickly as possible." Xu Xin said.

Then, he frowned slightly again.

"What are you thinking about?" Seeing his expression, Li Wenxi leaned against him and asked.

"Oh...it's about us."

After that, he and Ji Chaoyang asked Changyin and the monster many questions.

Xu Xin also asked the doubts in his mind.

But...he didn't get the answer he wanted.

First, he asked the monster about the altar.

As a result, he learned from the monster that the altar was not built by the monster.

It was only after it discovered Xu Xin and this group of people who were sent to the future that it discovered the two strange altars nearby.

There are two buildings nearby, one near Xu Xin's tree house at that time, and one near Ji Chaoyang's tree house at that time.

It can feel the energy of time and space from the altar, and there is also a special kind of energy.

The monster was very surprised when it felt this special energy, because it felt very familiar with it.

This energy is almost the same as the special energy that it has been studying for decades out of curiosity, those people in the underground city who somehow can still move after being petrified, and can even control the stones around them.

Consistent!

This is true for both altars.

The energy of the altar at that time was still very overbearing and would directly petrify and devour any creature that entered the altar!

That's right, it was swallowed, swallowed directly by the sunken ground.

But it is not death, but petrification. If you want to save the devoured creatures, you must use the flesh and blood of the same kind of creatures or the most special parts of the body to sacrifice, in order to free the petrified creatures from petrification.

…

"Ah, you mean the altar surrounded by hills?" Li Wenxi said in surprise, "It's not far from where we found the giant's head, right?"

"Yes, that's the altar. There was a similar altar at Ji Chaoyang's place at that time. At that time, we relied on this altar to resurrect the intermediate mutated creatures and then kill them, and we achieved first and second place in the standings at that time," Xu Xin said.

"Ah, I know this." Li Wenxi nodded, "You told me before."

"Huh? What are you talking about..." Lou Fei'er was confused, "Are you talking about hunting activities?"

She had never heard of this.

At that time, she still belonged to District 187. Later, she wanted to kill Xu Xin and was captured. She was not trusted for a long time, so naturally she had never heard of it.

"It's like this..." Li Wenxi simply explained it to her.

"Ah... there is such a magical place?" Lou Fei'er was surprised, and then she rolled her eyes, "Wait... then... then if you want Chang Yin and the others to return to human bodies, wouldn't they need... humans?

The flesh and blood and special parts of the body?”

Logically speaking, this is indeed the case.

In particular, the special energy in the bodies of the Changyin family is still the same as the energy in the altar.

Therefore, the monster ordered people to make mysterious sounds to tell the Changyin family that there was an altar on the ground, and they could restore their human bodies by making sacrifices.

Therefore, after Changyin's family came to the ground, they left Xu Xin.

Xu Xin later found traces of sacrifices made by Changyin's family in the altar.

However, the Changyin family seemed to have used the props in their hands to sacrifice at that time, so it was not successful. They were also deceived by alien invaders into the underground world to conduct experiments on petrifying giant beasts.

"Terrible... I remember you said that if you want to break a stone statue and let living creatures come out, you have to kill at least hundreds of their kind, right?" Li Wenxi murmured, "Then Chang Yin and the others...

"

If according to this ratio, if their family wants to transform from stone statues back to humans, they must at least...

Sacrifice hundreds of humans.

Changyin also fell silent when he learned about this.

But he also said that it was good to be able to change back to a human, but it didn't matter if he couldn't change back. At least the stone statue's body felt safer now.

"Hmm...how did the long seal turn into a stone statue?" Li Wenxi asked again.

"...I don't know." Xu Xin shook his head.

"Ah? Didn't Changyin tell you?"

"I told you, but...he said that the reason why he turned into a stone statue was because of the first batch of survivors." Xu Xin said.

The first time he met Chang Yin, he had already revealed some information to Xu Xin.

The first survivors did some very outrageous things to their family.

The first batch of survivors, that is, the first batch of humans brought by monsters thousands of years ago, are the only survivors who formed groups to survive together from the very beginning.

After all, they are the first batch, and the selection is not yet mature. The selection format is very different from the current survivor selection.

In this harsh environment, there is no law for group survival, and everything depends on strength. The evil in the nature of the strong will be infinitely magnified.

This is not to say that everyone is like this, but among the first batch of strong survivors at that time, there were quite a few such people.

And when I went underground and saw this family, it happened to be exactly this kind of person.

Changyin did not say what those people did to Changyin OnePlus.

But Xu Xin suddenly thought of the frightening carvings carved on the stone table in the underground city.

Among the random lettering, there are only a few legible fonts.

【They are all demons】

【Kill me, I want to die so much】

【You shall not die well】

When I saw it at that time, it made Xu Xin's heart stand on end.

The Changyin family was also petrified in this process. Then the survivors who entered the underground city were all turned into monsters worse than death by the Changyin family, and then stayed underground forever, in the flooded city.

In the underground city.

Therefore, Chang Yin always felt that it was those survivors who turned him into stone.

It's just that they got away with it and were killed by themselves.

But the monster said that this was simply impossible, and that those first survivors could not have this ability.

"Hey, wait a minute!" Li Wenxi interrupted Xu Xin and asked doubtfully, "Didn't the first batch of survivors come forty-eight years ago? Changyin was still a human being forty-eight years ago? He also experienced thousands of years

The disaster before? Who is he? A survivor from a thousand years ago? He lived fifty years ago? Is he a lackey of the alien invaders? "

"...I don't know. At least from Chang Yin's mouth, he didn't know about it. He was even extremely shocked that the world is now a thousand years later."
