After killing Wan Tianchou, the King of Ghost Evil respectfully walked up to Yun Sheng. He kneeled on one knee, lowered his head, and placed his right hand on his bare chest to pay his respects to Yun Sheng.

The posture no longer had the fierce demeanor from when he killed Wan Tianchou.

Yun Sheng was dumbfounded.

"What is this?" Yun Sheng was slightly stunned.

"Dear master, he’s acknowledging you," Bo Bo suddenly appeared, a little disgruntled that a big dude was competing for the master’s attention.

Ah, dear master’s everything is good, just too powerful, you see, yet another Summoned Beast has appeared, at this rate, Bo Bo will definitely fall out of favor.

Bo Bo was wallowing in self-pity, completely forgetting that it was the one who had always hoped Yun Sheng would get stronger and stronger, to have a better chance against that arrogant Netherworld God.

Though unhappy, Bo Bo’s biggest trait is optimism.

No matter how many Demon Beasts dear master has, Bo Bo is always the most important.

After understanding, Bo Bo had no reservations towards the King of Ghost Evil, knowing it was formed by the gathering of Ghostly Evil Energy from the Ghost King Cave.

Unexpectedly, such a small Ghost King Cave could have so much Ghostly Evil Energy.

Bo Bo wasn’t shy, fluttering its fleshy wings, landing on the King of Ghost Evil’s knee.

One was an extremely ugly ghostly evil, and the other a cute pink sheep.

Lantern-like big eyes meeting small black bean eyes, surprisingly, there was no repulsion between the King of Ghost Evil and Bo Bo.

The King of Ghost Evil tilted its head, showing an ugly yet obviously flattering smile to Bo Bo.

"Bo Bo, dear master, this big guy is very strong, and he’s different from usual ghostly evils." After some "spiritual communication" with the King of Ghost Evil, Bo Bo found this big guy to be a typical case of strong muscles and simple mind. With proper training, he would definitely be Bo Bo’s... oh, no, the master’s right-hand man.

Generally speaking, Yin Sha Energy is the most evil force; Bo Bo initially thought the King of Ghost Evil, formed by Yin Sha Energy, would also be a wicked and murderous figure. 𝓯𝙧𝙚𝒆𝙬𝙚𝒃𝙣𝙤𝒗𝓮𝓵.𝙘𝙤𝙢

But it wasn’t so; the Yin Sha Energy in the Ghost King Cave was different.

Back then, the Netherworld Ghost King had secretly captured numerous Mages and Martial Artists from the Human World while constructing the Ghost King Cave.

These individuals were imprisoned in the Ghost King Cave, tasked not only with excavating it but also with building its four major Magic Arrays.

After the Magic Arrays were completed, they discovered the Netherworld Ghost King had long left a deadly evil poison in their bodies.

One by one, the poison took effect, leading to their tragic deaths in the Ghost King Cave.

The King of Ghost Evil formed by their gathered Evil Souls was easier to control than those formed by common evil qi.

"Aww, so pitiful. Dear master, the King of Ghost Evil doesn’t have a name yet; why don’t we name him Big Fool?" Bo Bo’s heart went out to the King of Ghost Evil after hearing its tragic story, sympathetically giving a loud sniff.

Big Fool...

Yun Sheng rolled her eyes. How could she summon the awe-inspiring King of Ghost Evil with a name like that?

But the problem was, before Yun Sheng could object, the King of Ghost Evil eagerly nodded, indicating he liked the name very much.

Bo Bo immediately broke into a smile, happily playing with the King of Ghost Evil.

After killing Wan Tianchou, Yun Sheng took a moment to rest, waiting for someone to come out of the Teleportation Magic Array.

Unexpectedly, she waited for a full half hour.

There was no sign of activity from either of the Magic Arrays.

Those who could escape the Abyssal Tentacle Sunflower and enter the Ghost King Cave were already Martial God Level powerhouses; earlier, about twelve or thirteen individuals had entered the teleportation arrays.

Even if there was some powerful ambush or mechanism at the other end of the arrays, it was impossible for all of them to have been killed in this time.

Something’s wrong!

Could it be that the Teleportation Magic Array has other pathways?

Yun Sheng’s eyelids twitched, losing interest in waiting. Despite her calculations, she hadn’t accounted for the possibility of other paths deep within the Ghost King Cave.

Yun Sheng suddenly realized that Big Fool was formed from thousands of ghostly evils from the Ghost King Cave, so he should know what transpired within.

Yun Sheng’s heart stirred slightly.

"King of Ghost Evil, let me ask you, how did the Netherworld Ghost King die back then? Which of the two Magic Arrays actually holds the Ghost King’s corpse?" Yun Sheng initially planned to wait for the people from the Eight Prefectures of Netherworld to emerge before snatching the Heart Difficulty Lamp.

But quite some time had passed since the heroes entered the two Transmission Arrays, yet no one emerged; Yun Sheng couldn’t help but feel puzzled.

Back then, after the Netherworld Ghost King constructed the Ghost King Cave, where did he go?

In the end, who killed him?

Yun Sheng guessed that the answer might lie within one of the two Teleportation Magic Arrays.

"My lord, the Ghost King last entered the right Teleportation Array," Big Fool replied respectfully, his voice very low.

But what Big Fool could tell Yun Sheng was limited to this.

He didn’t know who killed the Netherworld Ghost King.

After entering the right Teleportation Array of the four Magic Arrays, the Netherworld Ghost King vanished without a trace. "Never appeared again? What does that mean?" Yun Sheng was greatly surprised.

The Ghost King Cave existed for as long as Big Fool did; earlier, due to the absence of Undead Summoners, Big Fool wandered in ghostly form within the cave.

Every disturbance in the Ghost King Cave was crystal clear to Big Fool, except for the four Magic Arrays.

But one thing was certain; the Netherworld Ghost King had entered the right Teleportation Array.

Since then, he completely vanished in the Netherworld.

Neither his subordinates nor his enemies could find any trace of him.

Some people had tried to enter the Ghost King Cave to find out about the Netherworld Ghost King’s fate, but those intruders either fell before the Sub-God Demon Beast Arrow-tailed War Rhinoceros or, like the Ghost King, mysteriously disappeared in the Teleportation Magic Array.

Gradually, for reasons unknown, news of the Netherworld Ghost King’s demise spread throughout the Netherworld.

"So, the Netherworld Ghost King merely disappeared? Moreover, is there something peculiar in that Teleportation Magic Array?" Yun Sheng asked, her gaze focusing on the right Transmission Array.

"You could say that; how could others possibly come out of a Magic Array that even the Netherworld Ghost King couldn’t escape," Big Fool nodded.
