"Also, since you are here, Jiang Er should also be there." Cao Yuan thought of this and relaxed, "She doesn't have life fluctuations herself, even if she uses the forbidden ruins, she won't be discovered, in this place, but her world is ......"

An Qingyu's eyes swept over Cao Yuan, pausing for a moment on those glowing chains, his brows furrowed slightly.

"These chains ......"

These chains pierced through Cao Yuan's body, stuck on his own bones, and completely locked his movements, not only that, but the ghostly light on the surface of the chains touched his bones, corroding the surroundings like sulfuric acid.

In An Qingyu's eyes, these ghostly lights were slowly eating away at Cao Yuan's body, but at the same time, there were also subtle wisps of pitch-black flames burning from Cao Yuan's body, fighting against these ghostly lights and stopping them from spreading.

"They are eating away at my bones, but the evil aura of the Black King flowing in my body can resist them, and I can'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 contained in it is far from being bearable by ordinary people, just like someone holding a chisel to chisel your bones little by little, and staying in the same range, the most important thing is that this pain is continuous......

Cao Yuan has gritted his teeth and endured it for nearly two years.

"It hurts." Cao Yuan grinned, "But I don't have any other advantages as a person, that is, I can endure it...... And I don't have any choice but to endure it. ”

An Qingyu's brows tightened, his gaze swept over these chains, took out a few black scalpels from his pocket, and said:

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

"Nope."

Cao Yuan shook his head decisively, "Those oracle envoys are still here, once you save me from the chains, they will definitely notice it, and we won't be able to leave at that time, you have finally mixed into the [Pure Land], there should be more important things to do." ”

"But you ......"

"Don't worry about me, it's just a little pain, I've been putting up with it for two years, is it still a while?" Cao Yuan smiled slightly, "Moreover, these chains continue to erode my bones, and they are tempered by the evil qi flames, and imperceptibly, I can feel that my body strength is getting higher and higher, and the control of the [Black King Slash] has also improved, which is also a kind of cultivation for me." ”

An Qingyu was silent for a moment, and said bitterly, "Your cultivation is too bitter." ”

"I don't have a brain as smart as you, I don't have the talent as strong as Nanaya, and I don't have the good luck of Chubby...... I want to keep up with your pace, how can I do it without suffering a little? Cao Yuan smiled and shook his head, "You go, leave me alone, do what you have to do, and when the time comes, 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 three more days!" An Qingyu's eyes flashed with firmness, "Within three days, I will definitely get rid of those oracle envoys, and then come back to save you!" ”

Solve the oracle in three days?

If someone else said this, Cao Yuan would definitely not believe it, but the person who said it was An Qingyu...... Then things are different.

An Qingyu said that if he can do it in three days, he will definitely be able to.

"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 was once again plunged into darkness, and the severe pain made Cao Yuan can't help but clench his teeth, but now, the piercing pain doesn't seem to be unbearable......

After a long time, a faint smile appeared on the corner of Cao Yuan's mouth:

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

……

"Qingyu, I have overwritten the surveillance records of you entering the cell and talking to Cao Yuan, and at the same time deleted all visitor records, they will not find out that you have been here."

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

"Well done."

"Are you really sure that you can dispose of the oracle in the [Pure Land] within three days?" Jiang Er's voice was full of worry, "Each of them is a powerhouse at the peak of the 'Klein' realm, and they all have powerful abilities, you still have half a step to step into the 'immeasurable' ...... now."

"Who said I'm going to kill them head-on?" An Qingyu pushed his glasses, the lenses reflected the miserable white light, and said lightly, "This last move, I have to bet a big one." ”

"I believe in you."

"How's the information from Subject 0?"

"It's been retrieved." Jiang Er's voice paused, and began to read the information about Subject 0 inside the [Pure Land]:

"Subject 0, whose real name is Yuzu Takibai, is thirteen years old, the son of the [Fierce Ghost] level wanted criminal Yuzu Kuritha, the second generation of 'King Blood' awakened, and the observation experiment lasted for thirteen years, two months and six days......

On September 16, 101 of the new calendar, the 138th purity test of 'royal blood' was conducted, and the test result was 0.13% higher than the 137th purity, and the analysis results were ......

On October 3, 101 of the new calendar, the intravenous injection of β-grade sixth-generation artificial hormones was carried out, and the mental strength was increased by 2.82%, and the analysis results were ......

On October 4, 101 of the new calendar, there was an adverse reaction of grade β artificial hormone injection, vomiting blood, pale complexion, loss of consciousness, injection of grade γ artificial hormones, forcibly inducing the body's potential, and woke up at 8:14:07 pm on the same day......

On October 19, 101 of the new calendar, the intravenous injection of β-level sixth-generation auxiliary artificial hormones was carried out......"

While listening to Jiang Er's test report for the last two months, An Qingyu's brows became tighter and tighter.

"What exactly are these oracles trying to do to this child...... Jiang Er, print me a complete experiment report for thirteen years, I want to study this experiment from scratch, I want to see what the hell this group of oracles who have mastered advanced technology are doing......

"Okay."

By the time An Qingyu returned to the central control room, an experiment report of more than 800 pages had been piled up on his desk, forming a small mountain.

An Qingyu entered the prison area this time, and Jiang Er escorted him all the way, hacked into the monitoring system, and deleted all the records he had appeared, so he did not arouse the alarm of other oracle envoys at all, and they didn't expect that there was an intruder in this [Pure Land] who was secretly getting along with them day and night......

An Qingyu sat at the low table, picked up the experimental report on the table, and carefully flipped through them one by one.

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

"This experiment...... Are these oracles crazy?! ”
