"Are you going to the Demon Realm?" Dongfang Bubai asked.

After dinner, Li Daoyi suggested that he go to the Demon Realm.

The Demon Realm, also known as the Underworld, is the territory of the Styx Ancestor in the Primordial Plane, beneath the Blood Sea. It is an independent small world created by the former Demon God Rahu.

In the previous primordial world, the Demon Realm disappeared with Rahu's self-destruction, but in the Journey to the West world, this small world still exists. After Wutian became a demon, he cultivated in the Demon Realm, and was later suppressed by Tathagata and imprisoned in the Demon Realm.

“Yes, I’ve thought about it, and this incident might be inextricably linked to Wutian,” Li Daoyi said.

Are you going alone?

Li Daoyi looked at Qiyu.

"Saitama is coming with me. I feel at ease with Mengmeng here."

"Um."

"Brother Daoyi, I want to go too." Mengmeng hugged Li Daoyi's leg tightly, rubbing her little head against him.

"Listen to me, stay here and protect your Sister Dongfang and Sister Long. We're just going to take a look, we'll be back soon," Li Daoyi said, patting Mengmeng's hair.

The little guy pursed his lips, but didn't argue, and obediently nodded.

The next day, General Hu and his companion arrived with rosy cheeks, presumably having eaten and drunk their fill the night before. They bowed immediately upon entering.

"Greetings, esteemed master."

"Get up!"

"What instructions do you have, sir?"

"I plan to explore the Demon Realm. You all stay in the city and don't go out."

"The Demon Realm..." The two were immediately shocked. That was a legendary place, and no one dared to go there.

"Master, isn't this too dangerous?"

"It's okay, Saitama is with me."

The two looked at Saitama, the Great Demon King, and, recalling his domineering demeanor from yesterday, couldn't help but swallow hard before saying nothing more.

“Grab me,” Li Daoyi said to Saitama.

Saitama quickly grabbed Li Daoyi's shoulder.

"Escape." Li Daoyi uttered softly.

The two then disappeared into the ground, vanishing from everyone's sight.

Saitama felt a force enveloping him, surrounded by darkness, a smell of earth, and a sensation of freefall.

After an unknown amount of time, Saitama felt the darkness before him turn gray, and his descent gradually slowed down.

Saitama looked down and saw an endless depression below, with a deep pit ten miles in circumference in the center.

"This must have been a lake, right?" Saitama looked around and then said. This depression looked like it used to be a lake, and the water seemed to have flowed away from the giant pit in the middle.

“The Sea of ​​Blood, this is the Sea of ​​Blood, it has dried up,” Li Daoyi said.

"Is it that pit?" Saitama asked.

Li Daoyi looked around. There was no sound near the sea of ​​blood, and it seemed that the Asura Clan could not escape their fate either.

“Hold on tight to me, let’s continue,” Li Daoyi said.

The two then fell into the giant pit.

Upon entering the giant pit, he was surrounded by smooth, black stone walls, as if they had been pierced directly by some kind of energy pillar. Li Daoyi pondered to himself that the power capable of causing this level of damage was already at the Hunyuan level. Moreover, judging from the smoothness of the stone walls, the energy was surging upwards from below, which should have originated from the Demon Realm below.

"Wu Tian, ​​what exactly happened to you?" Li Daoyi asked, somewhat puzzled.

They fell for about fifteen minutes before finally entering a huge space, where the remaining malevolent energy surged towards them.

Li Daoyi remained calm, reached into his hair, removed the hairpin, and tossed it casually forward.

The hairpin rapidly grew larger, quickly transforming into a dark-colored spear—the very same God-Slaying Spear that had been retrieved from the Underworld.

The God-Slaying Spear emitted bursts of eerie light, and the surrounding malevolent energy instantly surged into the spear and was absorbed by it.

"Buzz..." The God-Slaying Spear emitted a series of buzzing sounds, seemingly quite pleased.

"Suck it in..." Li Daoyi smiled.

"Wow, that's amazing." Saitama's eyes widened. Although he didn't have any magic power, his senses were not weak, and he could feel the power contained in the spear.

"Do you like it? If you like it, I'll give it to you," Li Daoyi said with a smile.

"Huh? Give it to me? But I don't know how to use it, and I don't have hair like you can plug it in. Never mind, never mind." Saitama said, scratching his bald head.

Li Dao rolled his eyes immediately. This guy was really unreliable; his reason for refusing was that he had no hair.

After a short while, the evil energy in the surrounding space had been completely absorbed. The God-Slaying Spear, still not satisfied, flew back to Li Daoyi and lingered around, as if it hadn't had enough.

"There wasn't much to begin with, so let's leave it at that for now. I'll let you eat as much as you want when we get back, but you might not be able to beat Mengmeng to it, hahaha." Li Daoyi said and burst into laughter.

"Buzzing..."

The God-Slaying Spear emitted a few aggrieved buzzing sounds, then slowly shrank and automatically flew back into Li Daoyi's hair.

The two flew downwards, heading towards a high platform resembling an altar. Scattered on the platform were many thick iron chains, and traces of an array could be vaguely seen around it, bearing many Sanskrit characters. Presumably, this was the place where Wutian was suppressed, and those iron chains were the instruments of torture used to bind him.

Saitama picked up a piece of iron chain that was thicker than his thigh and weighed it in his hand.

"Wow, it's quite heavy, it doesn't seem to be made of steel."

“This is a magical artifact, not steel. Alas, Wutian must have suffered a lot,” Li Daoyi said.

"Where is he?"

Li Daoyi didn't speak, but walked to the middle. There were two deep marks there, the marks left by people kneeling. It was clear that Wutian had knelt here when he was locked up.

Li Daoyi squatted down, reached out and stroked it, then closed his eyes.

"boom..."

A powerful energy erupted from his body, and Saitama was directly blasted back to the edge of the platform by this force.

Then Saitama looked up at Li Daoyi and saw a huge white figure behind him, its appearance unclear in a blur.

“Time rewind,” Li Daoyi said in a deep voice.

An energy spread outward from the center of the platform, and then the surroundings began to change. Suddenly, phantom images appeared on the chains on the ground. These phantom images began to emerge from the scattered chains, and then they recombined into three complete iron chains. The phantom chains inserted themselves into the platform, and then these chains began to fly along the central position.

Slowly, a black figure appeared where Li Daoyi was. Dressed in black, with long, flowing hair and a pale, arrogant face, it was the phantom of Wutian in black.

The phantom of Wutian showed a pained expression, with black lines like earthworms wriggling on his face.

Wutian was wailing in agony. Although there was no sound on the screen, one could still feel the heart-wrenching pain. Then, Wutian suddenly looked up, his eyes turned black, and the screen disappeared.

The illusory figure behind Li Daoyi slowly disappeared, and the oppressive feeling also vanished. Saitama leaped over.

"What's wrong with him?" Saitama asked.

“They’ve been infected, but we can’t figure out why. Sigh, it’s just a trial card after all, it’s too restrictive,” Li Daoyi said in a deep voice.

Just then, a faint light appeared where Wutian's knee mark had been.

"Huh?"

Li Daoyi quickly squatted down again, reached out and touched it, peeling away the layer of black dust to reveal two lines of writing inside.

"Goodness is gone, and evil thoughts have arisen."

"When the Heavenly Demon descends, I am no longer myself."

Li Daoyi read it aloud softly.

"What do you mean?" Saitama looked completely bewildered.

"Sigh..." Li Daoyi sat down cross-legged, looking sadly at the gloomy sky of the Demon Realm.

“It’s my fault,” Li Daoyi said in a deep voice.

"..." Saitama still scratched his head, completely bewildered.

"The White-Clad Wutian was his benevolent self. After I summoned him, I gave him a new life, but I also stripped him of his benevolent self identity. Without his benevolent self, the Black-Clad Wutian lost the goodness in his heart. Over time, he developed inner demons. Perhaps his inner demons communicated with some evil beings in other worlds. At that time, the Black-Clad Wutian was locked up and could not do anything. He could only watch helplessly as his body was devoured."

"The final scene just now explains everything. Wutian was completely controlled by his inner demons, which gave him the ability to break free and summon extraterrestrial demons into this world, leading to the current situation," Li Daoyi sighed.

Saitama remained silent upon hearing this. Although he did not know Black-Clad Wutian, he and White-Clad Wutian were very close in the previous world, and he was very saddened to learn of this outcome.

"Are those extraterrestrial demons very strong? Aren't so many gods no match for them?" Saitama asked.

"Do you know about the virus?" Li Daoyi asked.

As a person from the civilized world, Saitama naturally knew, so he nodded.

"If a person with a cold goes to a secluded island, the cold virus he carries will cause unpredictable harm to the island's natives. You can't say that the cold virus is powerful, but the natives just happen to be unable to resist it. This kind of evil is the same principle."

“They are not strong, but they can cause great harm to cultivators. If it were you, these evil spirits would not be able to harm you at all, because you have no magic power.” Li Daoyi patted Qi Yu and said.

"I see." Saitama nodded.

"Let's go, let's leave here and go see the underworld."

Then Li Daoyi grabbed Saitama and flew away again through the hole above his head.

The moment he entered the cave, Li Daoyi reached out and pressed down.

The high platform that once locked up and suppressed the tyrannical ruler collapsed.

"Wu Tian, ​​I'm sorry." Li Daoyi sighed softly, then flew into the cave.
