Chapter 2424

Later, as if recalling past events, he continued, "One of the karmic merits that allowed the Black Emperor to ascend to the position of Emperor Venerable was the destruction of a Heavenly Demon Spirit capable of devouring and destroying. This act saved the living beings of heaven and earth, securing his status. That event occurred tens of thousands of years ago. I never expected the Heavenly Demon Cave to reappear now."

"This Heavenly Demon Cave sounds terrifying," Zhu Yanyi said softly from the side.

"It is essentially a black hole," Yan Aohan explained to Zhu Yanyi promptly. "The principle of the Heavenly Demon Cave is similar to that of a black hole. No one knows the exact magnitude of a black hole's power, but anything that enters it simply vanishes."

"Does the appearance of the Heavenly Demon Cave indicate something is wrong with the Yunhe River?" Zhu Yanyi asked.

Yan Aohan shook his head. "It has nothing to do with the Yunhe River. The emergence of the Heavenly Demon Cave is linked to the human heart. The darkness within human hearts gives rise to evil spirits, which eventually converge to form the Heavenly Demon Cave."

Zhu Yanyi suddenly understood. "So, does that mean the Heavenly Demon Cave will never disappear?"

As long as there are people, there will be dark sides. With dark sides comes dark energy, which naturally leads to the continuous emergence of evil spirits and Heavenly Demon Caves.

Yan Aohan nodded. "Indeed, that is the case."

Zhu Yanyi tapped her forehead. "Then, now that the Heavenly Demon Cave has disappeared, what do you plan to do?"

"I can only have people patrol the Yanluo Realm to prevent the Heavenly Demon Cave from appearing there. To destroy this Heavenly Demon Cave, we must rely on the Black Emperor. His abilities are the perfect counter to this Black Demon Cave."

Hearing this, Zhu Yanyi breathed a sigh of relief. "It is good that there is a counter."

"It is naturally good that there is a counter, but we must also prepare for prevention. To be honest, the appearance of this Heavenly Demon Cave surprises me. I always believed it would take at least hundreds of millions of years for one to appear. I never expected it to happen after only tens of thousands of years. Could there be something unexpected happening here?" Yan Aohan frowned slightly.

The Immortal Emperor said, "I have already sent people to investigate this matter. However, what worries me is that the Heavenly Demon Cave appeared and then disappeared. That is what is truly concerning."

"Isn't its disappearance a good thing?" Zhu Yanyi asked, confused.

"This disappearance is not that disappearance. This disappearance likely means the Heavenly Demon Cave is lying dormant. If that is the case, it implies the Heavenly Demon Cave has gained sentience. Once it has sentience, no one knows where the final outcome will lead. It might even nurture a resurrected soul and then possess someone. If that happens, the world will fall into chaos." The Immortal Emperor looked worried. He was not exaggerating; after all, when the Heavenly Demon Cave first appeared, it truly brought disaster.

Zhu Yanyi frowned slightly. She understood the Immortal Emperor's concern, but she did not know what to say, as she had no ability to stop this black hole. Yan Aohan thought for a moment and said, "For now, we can only defend. Let us wait for the Black Emperor to arrive. Have you sent her a message?"

"I have." The Immortal Emperor nodded. "He should arrive soon."

In fact, he arrived quite quickly, as the Black Emperor tore through the void to get there.

Yan Aohan saw the Black Emperor and said, "I was worried about my wife, so I flew slowly. You tore through the void, yet you arrived later than me." Yan Aohan knew the Black Emperor was not the type to be late without reason, so he must have been occupied with something.

"After receiving the news that a Heavenly Demon Cave appeared and disappeared in the Yunhe River, I specifically went to the place where I originally destroyed the Heavenly Demon Cave to take a look. Do you know what I found?" The Black Emperor looked at the Immortal Emperor, Yan Aohan, and the others.

"Did something happen?" The Black Emperor’s words suggested that something serious might have occurred.

"As everyone knows, Heavenly Demon Black Holes cannot be completely destroyed. Therefore, I originally only sealed the Heavenly Demon Black Hole. This time, when I went there, I found that the original seal was still intact. However, I discovered that a derivative body spawned from that original Heavenly Demon Black Hole had escaped through a nearby crack."

The Black Emperor looked at everyone with a helpless expression. "So, I suspect that the Heavenly Demon Cave that appeared recently is likely a derivative of that original Heavenly Demon Cave."

Seeing how naturally the Black Emperor spoke, Yan Aohan’s eyes flashed with sharp light. He chuckled. "In that case, you handle this matter."

The Black Emperor pursed his lips. "You cannot be so heartless."

"What does my heartlessness have to do with it? I don’t think it matters," Yan Aohan said calmly. "I have no time to deal with this right now. The Yanluo Realm has a pile of matters to attend to. Unless the Heavenly Demon Cave appears in the Yanluo Realm, I will handle it. But you know, the probability of a Heavenly Demon Cave appearing in the Yanluo Realm is zero."

The Black Emperor sighed. "How should I put it? Although it is unlikely for a Heavenly Demon Cave to appear in the Yanluo Realm, because this Heavenly Demon Cave is a derivative, it might transform into a soul and hide in your Yanluo Realm. Then, through reincarnation, it enters the human world, thus gaining new life."

Yan Aohan tilted his head, looking at the Black Emperor. "Is it stupid? The Yanluo Realm today is not the Underworld of the past. The system in the Yanluo Realm is very strict. To reincarnate, one needs an identity certificate. Without an identity certificate, it will be dealt with. All souls have identity certificates. This is common knowledge. If there is no identity certificate, it is an extra soul. Such a soul cannot even approach the Reincarnation Platform, let alone pass the review. It will be directly destroyed by the Soul-Extinguishing Thunder of the Yanluo Realm."

The Black Emperor said calmly, "It is a derivative. Its only impression of the Yanluo Realm is what the Underworld looked like in the past. Therefore, it naturally does not know that the Yanluo Realm has changed."

Yan Aohan had nothing more to say. "I will keep an eye on the Underworld side. But I think you should focus on other things. Just because the Yanluo Realm will not have problems does not mean other places will not."

The Black Emperor hummed. "I have thought about it. I plan to go to the Yanluo Realm with you first."

"What are you going to the Yanluo Realm for?" Yan Aohan looked at the Black Emperor, his eyes full of confusion.

"To help you investigate this Heavenly Demon Cave," the Black Emperor said seriously.

"No need. You are a demonic cultivator. You are not suitable for the Yanluo Realm," Zhu Yanyi refused.

Yan Aohan glanced at Zhu Yanyi, then smiled and said to the Black Emperor, "That is correct. You are a demonic cultivator. The cultivation energy in our Yanluo Realm is soul Yin energy, not demonic energy. Therefore, you are not suitable for the Yanluo Realm."

"But I am not at ease," the Black Emperor continued.

"You are not at ease with us?" Yan Aohan dragged out the words. He immediately struck out with a palm. "I am not at ease with you either. What kind of ghost thing are you, daring to transform into the Black Emperor’s appearance?"
