"That's right. Since you're here, Jiang Er should be here too." Cao Yuan thought about this and relaxed. "She doesn't have any life fluctuations, so she won't be discovered even if she uses the Forbidden Ruins. This place is her world..."

An Qingyu's eyes swept over Cao Yuan, pausing for a moment on the glowing chains, and frowned slightly.

"These chains..."

These chains pierced through Cao Yuan's body and got stuck on his bones, completely locking his movements. Not only that, the faint light on the surface of the chains came into contact with his bones, corroding the surroundings like sulfuric acid.

In An Qingyu's eyes, these faint lights were slowly devouring Cao Yuan's body, but at the same time, there were wisps of tiny black flames burning from Cao Yuan's body, competing with these faint lights and preventing them from spreading.

"They are eating away at my bones. However, the evil spirit of the Black King flowing in my body can resist them and I won't die." Cao Yuan smiled palely.

"Aren't you in pain?" An Qingyu frowned and looked into Cao Yuan's eyes.

This process sounds simple, but in fact, the pain involved is far beyond what most people can bear. It is like someone chiseling your bones little by little with a chisel, and it stays in the same area. The most important thing is that this pain is continuous...

Cao Yuan has been gritting his teeth and enduring for nearly two years.

"It hurts." Cao Yuan grinned, "But I don't have any other advantages. I can endure it... and I have no other choice but to endure it."

An Qingyu frowned, glanced at the chains, took out a few black scalpels from his pocket, and said:

"I'll help you cut these chains..."

"no."

Cao Yuan shook his head decisively, "Those oracles are still here. Once you rescue me from the chains, they will definitely notice something, and then we will all be unable to leave. You have finally managed to sneak into the Pure Land, so you should have more important things to do."

"But you..."

"Don't worry about me. It's just a little pain. I've endured it for two years. Is it going to take another moment?" Cao Yuan smiled. "Also, these chains are constantly corroding my bones. They are tempered by the evil flames. I can feel my body getting stronger and stronger. My control over [Black King Slash] has also improved. This is also a kind of practice for me."

An Qingyu was silent for a moment, then said bitterly, "Your practice is too hard."

"I don't have a brain as smart as yours, a talent as strong as Qiye, or luck as good as Pangpang... If I want to keep up with you, how can I do it without suffering a little?" Cao Yuan smiled and shook his head, "Just go, don't worry about me, go do what you should do, and when the time is right, come back to save me."

An Qingyu stood in front of Cao Yuan, pondered for a long time, and nodded heavily.

"Okay, three days, give me another three days!" A firm look flashed in An Qingyu's eyes, "Within three days, I will definitely get rid of those oracles and come back to save you!"

Get rid of the oracle in three days?

If someone else said this, Cao Yuan would definitely not believe it, but if the person who said it was An Qingyu... then the situation would be different.

If An Qingyu says that we can do it in three days, then we can definitely do it.

"Okay." Cao Yuan nodded, "I'll wait for you."

An Qingyu took one last look at him, turned around decisively, and strode towards the door.

When the prison door was closed, the cell fell into darkness again. The severe pain made Cao Yuan grit his teeth, but now, the piercing pain did not seem unbearable...

After a long time, a faint smile appeared on Cao Yuan's lips:

"It's really reassuring to have a companion..."

…

"Qing Yu, I have overwritten the surveillance records of you entering the cell and talking to Cao Yuan, and deleted all visitor records. They won't find out that you have been here."

Jiang Er's voice sounded in the Bluetooth headset, and An Qingyu nodded slightly.

"here you go."

"Are you sure you can get rid of the Oracles in the Pure Land within three days?" Jiang Er's voice was filled with worry. "Each of them is a Klein-level peak warrior, and they all have powerful abilities. You are still half a step away from entering the Infinite Realm..."

"Who said I was going to kill them head-on?" An Qingyu pushed up his glasses, the lenses reflecting the pale light, and said calmly, "For this last move, I'm going to take a big gamble."

"I trust you."

"How is the information of Subject 0 being retrieved?"

"It has been retrieved." Jiang Er paused and began to read the data about Subject No. 0 from Pure Land:

"Subject No. 0, real name Yuuri Takishiro, thirteen years old, son of the [Ghost]-level wanted criminal Yuuri Kurotetsu, second generation 'Royal Blood' awakener, the observation experiment lasted for thirteen years, two months and six days...

On September 16, 101, the 138th purity test of the "Royal Blood" was conducted. The test results showed that the purity was 0.13% higher than that of the 137th test. The analysis results showed that...

On October 3, 101 of the new calendar, a beta-level sixth-generation artificial hormone was injected intravenously, and the mental strength increased by 2.82%. The analysis results...

On October 4, 2012, he had an adverse reaction to the beta-level artificial hormone injection, vomited blood, had a sallow complexion, and lost consciousness. He was injected with gamma-level artificial hormones to forcefully stimulate his body's potential, and he woke up at 8:14:07 pm that day...

On October 19, 101 of the new calendar, a beta-level sixth-generation auxiliary artificial hormone was injected intravenously..."

While listening to Jiang Er reading the experimental report of the past two months, An Qingyu's brows became more and more furrowed.

"What on earth do these oracles want to do to this child... Jiang Er, print me a complete experimental report for the past thirteen years. I want to study this experiment from the beginning. I want to see what these oracles who have mastered advanced technology are up to..."

"OK."

When An Qingyu returned to the control room, an experimental report of more than 800 pages was piled on his desk, forming a small mountain.

This time, An Qingyu entered the prison area with Jiang Er escorting him all the way. He hacked into the surveillance system and deleted all the records of his appearance, so he did not arouse the vigilance of other Oracles at all. They did not expect that there was an intruder in this [Pure Land], living with them day and night in secret...

An Qingyu sat at the low table, picked up the experimental reports beside the table, and read them carefully one by one.

As time passed, the surprise in An Qingyu's eyes became more and more intense. In the end, his eyes were full of shock!

"This experiment...are these oracles crazy?!"
