"This prison you just entered is actually a pilot project for breeding stone creatures," Chang Yin said gravely. "You should have seen the experimental creatures in the underground warehouse, right? Those are actually underground creatures in the experimental stage, and haven't yet fully become stone creatures."

Xu Xin narrowed his eyes slightly.

Is that really the case?

The entire underground prison is actually a breeding ground for petrified creatures.

"Cultivating stone creatures here?" Ji Chaoyang frowned slightly. "Those stone creatures we encountered before were all cultivated underground?"

However, others were not surprised because they had heard this speculation a long time ago.

They all turned to look at Xu Xin.

"You guessed it right, Brother Xin!" Wang Lei said with admiration.

"I didn't expect it to be true!" Wen Guixin sighed.

Instead, Ji Chaoyang looked at them in surprise: "What did you... encounter underground?"

"The following is a bit complicated. I'll explain it to you later."

Xu Xin continued to look at Chang Yin and said, "So, what is the situation now, and what is your relationship with this underground prison?"

Chang Yin hesitated, but still spoke, "Well, I... can be said to be a researcher in this underground prison. Actually, the petrification technology was provided by me. It can be said that everything about the stone statues you encountered near the teleportation formation originated from me."

"What?!" Zhao Xiaochuan exclaimed.

"The technology you provided?!" Wang Lei was also a little bit unbelievable.

"...Those stone statues outside are all your work?" Wen Guixin couldn't help but be shocked.

Xu Xin and Ji Chaoyang also looked at each other and could see the surprise in each other's eyes.

The two had actually made such a guess a long time ago, but hearing such things come out of their own mouths was too shocking.

"Well... I can't say I made all of them, but..." Chang Yin touched his chin with his hand, making a sound of stones rubbing against each other. "To put it simply, I'm the only one who possesses the core technology. It can be said that without me, these stone statues would not have been created."

"So..." Xu Xin frowned slightly and looked at him, "Are you the mastermind behind this?"

"Of course not." Chang Yin pretended to sigh, but of course, his stone body had no breath to sigh out. "I was forcibly brought here to be experimented on by them."

Then he began to explain their current situation and where this place was.

As he continued to explain, the expressions of the people present gradually became solemn.

The origins of the creatures in the underground world are basically the same as they had previously deduced.

These creatures have awakened their own consciousness because the bloodline of the giant beast is stronger than the blood pattern mutation, making it impossible for the "Blood Pattern Clan" to control them.

So, they simply threw all these huge guys into the ground.

This incident happened forty-eight years ago.

That is, before the first survivors appeared.

In this way, the prototype of the underground world was born.

This group of underground creatures have been a group of mutant creatures from the very beginning. Moreover, they are mutant creatures that possess the blood of giant beasts and have undergone blood pattern mutations.

These two variations coexist but conflict with each other.

This also results in the genetic instability of this group of creatures living underground.

During the initial period, this group of creatures were undergoing individual mutations almost every day!

That’s right, it’s not group variation caused by reproduction, but individual variation!

Not only are the genes in the body changing rapidly, but even the body shape and traits are changing rapidly.

The same creature may look completely different from one day to the next!

The entire underground world was in great chaos at that time.

Extremely chaotic.

Every day, there is genocide, and every day, new species are born.

During this process, the "Blood Pattern Clan" continued to send new Blood Pattern beasts into this underground world.

The underground world is undergoing earth-shaking changes every day.

This process lasted for more than ten years.

That’s right, when the first batch of survivors came to this world, the underground world was still a complete mess!

Of course, the entire underground world finally stabilized after more than ten years, when the Blood Vein Clan stopped sending new Blood Vein behemoths into it.

In this way, after nearly fifty years of evolution, the underground world that they see now emerged, which looks somewhat vibrant and has a relatively stable ecology.

"Is this how this underground world was formed? Your logic doesn't make sense, does it?"

Zhao Xiaochuan asked with some doubt, "Just because they're disobedient, they dug out this underground world and put them in? This... is too much trouble, right? They're just looking for trouble!"

"That's right!" Wang Lei nodded. "This underground world is so deep. If we want to transfer the creatures down, we must first subdue them, right? Then killing them should be easy, right? If that's the case, why bother with so much effort to get them down?"

"We don't kill them because they are still useful, right?" Lou Feier speculated, then glanced at Xu Xin.
