The team marched towards the cave.

Xu Tianhai walked at the front of the line as the front row, and he released stars and dots on him.

At this time, only Nangong Yan and a Six-colored Danwang Elder could stand by her side.

Xu Tianhai said that once he activated the holy weapon, it would be safe within half a meter of his side, so that he would not be affected by the holy weapon on the other side.

Luckily, they entered the cave for a while, but they didn't find any monsters, and they didn't find any signs of monster activity here.

After entering the cave, they found that it was a huge karst cave inside.

They can't use their Divine Sense to probe here, so they can only keep their eyes open to see what's going on around them.

Soon, Xu Tianhai and others found some clues.

"He should be right in front!"

They saw some 'fresh' humanoid footprints on the ground, and they could tell from the 'fresh' humanoid footprints that the burly man in black was nearby.

They looked around nervously, looking around warily.

"Where is he?"

The same thought flashed through their minds.

They found that they were surrounded by various towering stone pillars, and it was difficult for them to find the burly man in black.

The team continued for miles, and suddenly, they saw a faint green light in a cave in front of them.

They immediately prepared for battle and cautiously lurked past.

Before he got close to the cave, Xu Tianhai first accepted the holy weapon on the other side, and after letting Nangong Yan and the Elder of the Six-colored Danwang leave, he opened the holy weapon on the other side again, and then sneaked into the cave.

He didn't know what was going to happen to him next, so he let the two of them go just to be safe.

Once inside the cave, he could see the surroundings around him.

He saw a large green luminary in front of him, and next to that huge green luminous figure, on a stone wall, there was a black figure clinging to the stone wall.

Xu Tianhai immediately recognized that the black figure was the Immortal Evil King.

After the Immortal Evil King saw Xu Tianhai appear, he didn't say a word, and rushed over directly.

Xu Tianhai immediately opened the holy weapon on the other side, and his body also rushed towards the immortal evil king.

The immortal evil king saw that starlight suddenly appeared on Xu Tianhai's body, and he thought of its terrifyingness.

Although he didn't know why starry light suddenly appeared on Xu Tianhai's body for no reason, he knew that once the starlight really appeared on the other party's body, those demonic beasts that attacked him would all disappear for no reason.

He knew he had to be wary of this anomaly.

How dare he rush towards Xu Tianhai again, he just wants to dodge and avoid the starlight on the other party's body.

But the next moment, he found that he couldn't dodge at all, and then, he felt that his eyes were black, and then he was enveloped in a powerful teleportation energy, teleporting him to other places.

"Where is this?"

After the teleportation energy was gone, he looked around and found that he had come to a very strange space.

"This immortal evil king, you can rest here, don't worry, it's safe here!"

Immediately after, he heard Xu Tianhai's voice.

"Who are you, and why are you trapping me here?"

The Undead Evil King asked.

"Immortal Evil King, you are now trapped in my holy weapon, you don't want to get out of the holy weapon alive, this holy weapon can lock up all monsters for a lifetime!"

Xu Tianhai replied.

"So you mean I don't need to be stranded on the Isle of Eternal Darkness anymore?"

The Immortal Evil King asked suddenly.

"It should be!"

Xu Tianhai frowned slightly, he felt that the immortal evil king was trapped here, which should be related to his racial identity.

"Let me ask you, Immortal Evil King, are you a demon or a natural spirit?"

Xu Tianhai hurriedly asked.

"Guess what!"

The Immortal Evil King sneered and said.

"Oh, I just forgot to tell you, if you're a demon clan, then when we go out, you're still going to be hit by lightning here, and if you're a natural spirit, you'll be able to get out of here safely!"

"I'm a demon! I'm not a natural creature!"

When the Immortal Evil King heard this, he immediately became anxious.

"I see!"

Xu Tianhai suddenly realized, and he understood why he was afraid of lightning.

Under normal circumstances, the demon clan is very afraid of lightning.

"Are you tempting me?"

The Immortal Evil King immediately understood.

"I'm not tempting you, I just don't want accidents! What is this place, and why are you imprisoned here?"

Xu Tianhai asked.

"I was imprisoned here by a very powerful person, who sealed my people here, fortunately, I escaped at that time, but my people were sealed inside, and they all died!"

The Immortal Evil King said with a sigh.

"You mean to say that your people are sealed in the giant luminous body in front of you?"

Xu Tianhai frowned slightly, and he thought of a possibility.

"Yes!"

The Immortal King replied.

"Then what is your true nature? Immortal Evil King, you have to reveal your true nature to me! I will find out the truth for you!"

Xu Tianhai said.

"Okay!"

The Immortal Evil King immediately revealed his body, which turned out to be a giant turtle.

But unlike ordinary turtles, its shell shimmers with an unusual light.

After seeing its body clearly, Xu Tianhai suddenly realized.

"Your body turned out to be a nine-colored turtle! I know why that person wanted to seal your clansmen! That person wants to boil your clan's life essence into a nine-colored longevity liquid! This nine-colored longevity liquid can make a person live longer, at least it can increase the longevity for hundreds of years!"

"I see!!"

When the Immortal King heard this, he wailed.

"Our people didn't do anything, why did God do this to them? They died so miserably!"

"What are you crying for? Is it useful for you to cry? I ask you, do you know how to get out of here?"

"I know, but why should I tell you! unless you're willing to get revenge on me!

The Undead Evil King threatened.

"Don't think about revenge, let me tell you, I think this crystal is at least three hundred years old, this is exactly the history of this place becoming an eternal dark island, generally speaking, if you want to boil into a nine-colored immortal liquid, it will take at least three or four hundred years of history, I estimate that person will come here soon! I think that person's strength is not weak, he should be a strong person in the Dao Heaven Realm! Because, only the powerhouses of the Dao Heaven Realm can take the nine-colored elixir, this nine-colored elixir is not something that ordinary people can take, if it were me, and if I take it now, I can only explode and die!"

Xu Tianhai pondered for a while, and finally said his guess.

"The other party leaked your fish that slipped through the net, maybe once your clan was sealed inside, if you want to disassemble this crystal, you can only scrap your previous efforts, therefore, that person will let you go! It's not that you're powerful, but this crystal can only be molded at one time!"

Xu Tianhai told the truth.

"I see!"

The Immortal Evil King is in despair.

"What's going on with that Nangong Leng, and how did he get in?"

Suddenly, Xu Tianhai thought of Nangong Leng.

"I don't know how he got in, but one day he was wandering out and I sent my men to arrest him!"
