They hurried down the dark stone staircase.

At first, there were no lights at all underneath, and they had to be lit by torches.

After advancing for a while, they saw a faint and soft light emitting from the stone walls in front of them.

When they looked closer, they saw that there were a large number of night pearls on both sides of the stone wall.

"Don't touch these Night Pearls, these Night Pearls may trigger some kind of trap!"

At this moment, Mo Ruyu hurriedly said.

She didn't want the disciples around her to be curious or greedy for those night pearls, and touched the magic circle here.

"They've been here before!"

Xu Hai saw a mess of footprints on the ground, and those footprints were numerous, and they were all very fresh.

The aisles are covered with dust, so when those footprints are stepped on the aisles, they leave clear marks.

When Xu Hai and the others saw those clear traces, they concluded that Mo Youqian and the others had been here before.

They moved forward for a moment, and then they saw a stone gate appear in front of them.

The stone door was opened.

They walked slowly and heard the sound of running water in front of them.

"There's an underground river here!"

Xu Hai immediately thought of this possibility.

When they walked out of the stone gate, they actually saw an underground river appear in front of them.

I saw that the underground river was rushing and gurgling.

They looked around, but they didn't see any road signs nearby.

"In which direction are they going?"

Xu Hai's Divine Sense was released, however, to his disappointment, he found that there was a strong Divine Sense Shielding Detection Power here, making his Divine Sense Detection ineffective.

Now he can only see the source and flow of the underground river with the naked eye.

"In which direction will they go?"

At this time, this thought flashed through their hearts.

"Xu Hai, should you and us go towards the source of this river, or go downstream?"

Mo Ruyu asked.

"I don't know much about this, I think we should go to the source, if the source doesn't have any clues, let's go downstream!"

Xu Hai said lightly.

"That's all there is to it!"

Her eyes widened, scrutinizing her surroundings.

However, she didn't find any clues from her father in the surrounding area.

"You stay on the shore and don't move, I'll dive down and see!"

After Xu Hai finished, he jumped and jumped into the Linxia River Zheng

He had stabbed into the underground river with the Wind and Thunder Sword before, and he found that the underground river was very deep.

His current cultivation was enough for him to be able to rest underwater for ten nights, and he didn't need to worry about the lack of oxygen.

Others were just waiting on the sidelines.

After Xu Hai dived into the underground river, he swam in the direction of the source.

He kept swimming ahead, and soon, he saw a large number of cave stone pillars in front of him.

"This place is so big! Looks like I'm going to have to make a mark here, or we're going to get lost here!"

His mind moved, and he waved his right hand.

The Wind and Thunder Sword was sharpened by his envoy, and a stone pillar was sharpened.

Now, the shape of the pillar resembles the tip of a spear.

Xu Hai also carved a number on the stone pillar.

Then he continued to move forward.

After advancing for a while, he saw a dense pile of stone pillars in front of him.

His brow furrowed, he knew that if they didn't remember the way they came, they might easily get lost in Stone Pillar Zheng

In order not to get lost, as soon as his mind moved, he used the Wind and Thunder Sword to cut off the heads of all the stone pillars in front of him.

After doing all this, he moved on.

When he passed some bends in the river, he would use his sword to leave sword marks on them.

He advanced about a few hundred meters, and finally, he saw a waterfall up to 100 meters in front of him.

The sides of the waterfall were very smooth, and he wanted to cast a flying spell, but found that he still couldn't cast a flying spell here.

He took a deep breath, and he thought of an easy solution, which was to keep blasting a pit in the rocks of the waterfall with the Wind Thunder Sword.

Then he could step on the pit and go up one step at a time.

An hour later, the Wind Thunder Sword finally blasted out hundreds of pits.

He took a deep breath, and after taking some Ning Dan Xian Dan and Shen Yi Xian Dan, he rushed forward.

After dozens of breaths, he rushed to the top of the waterfall.

When he went up, he saw a pavilion-like building on it.

He immediately entered the gazebo in front of him, and after a careful examination, he found that there were no footprints in the ground of the gazebo.

He concluded that Mo Youqian and the others should not have been here before.

"Looks like they're heading down the river!"

He immediately entered the gazebo, he looked around, and soon he saw that above one of the caves, there seemed to be traces of buildings.

So, he went to the bottom of the cave and looked for clues.

Suddenly, he felt a sharp pain in his chest.

His complexion changed dramatically, and his heart beat violently.

He really couldn't figure out when he had been plotted, and he wondered if he might have been poisoned.

He hurriedly ran the exercises, holding his breath.

Then, he immediately took off his shirt, and he wanted to see what was wrong with his chest.

The next moment, he saw a red 'blood vessel' appear in his heart.

The 'blood vessels' stretched from his heart to the palm of his right hand.

Seeing this, his face changed greatly, and his heart was shocked, and he immediately thought of a possibility.

"Could it be that the curse in my body is backlashing? It's just that this curse is backing up too quickly, isn't it? Why did this curse backlash suddenly erupt?"

He pondered for a moment, and then thought of a possibility.

"Could it be that Xu Yifan is around here?"

He wanted to find Xu Yifan as soon as possible and settle the grievances between them.

"Looks like he might be here!"

He let out a breath of turbidity, and when he had stabilized the sharp pain in his body, he immediately climbed to the top of the cave to check what was going on.

When he climbed to the top of the cave, he saw that it was a very clean tower.

"How can this tower be so clean? Has anyone been here before?"

He checked, and soon he found that there was a hole in the top of the tower that could only hold one person through.

His eyes flashed, and he immediately activated the flying spell.

The next moment, he sensed that he could fly here.

He took a deep breath and flew up the hole.

After a while, he flew out of the hole.

As soon as he flew out, he saw an unfathomable cliff beneath his feet.

He looked around again, and saw that he was at the bottom of a very hidden cliff corner.

It would be very difficult for ordinary people to find the place where he was now.

The place where he was now was very secretive and not easy to spot.

"It seems that Mo Youqian should be heading downstream!"

Xu Hai immediately flew down the cave, and he returned to the tower.

He immediately returned the same way, and he knew that the next thing he was going to do was to lead Mo Ruyu and the others to find Mo Youqian and the others' whereabouts.

An hour later, he finally returned to the place he had agreed with Mo Ruyu and the others before.

But to his surprise, he didn't see anyone staying.

"What about them?"

So, he immediately rushed in to find Mo Ruyu and the others.

After a while, he returned to the hall Zheng

At this time, there were still a large number of Youdao Academy disciples in the hall.

They stayed where they were, and they didn't go anywhere.

Seeing them, Xu Hai immediately asked, "Disciples, have you seen Mo Ruyu, Mo Youqian and the others? Have they ever come up?"

"No, none of them have come up except you!"

"We've been staying here and not going anywhere! we've just seen you come up alone!"

The disciples replied.

Xu Hai immediately gasped when he heard their answers.

He pondered that it was very likely that Mo Ruyu and the others were going downstream, but he couldn't understand why they didn't stay where they were and wait for him.

"What the hell are they doing?"

Xu Hai exhaled a breath of turbidity, and as soon as his mind moved, he immediately walked down the underground passage.

Soon, he came to the place where the river was under the rain.

He took a deep breath and dived into Shui Zheng

Ten breaths later, suddenly, he saw a boat appear below.

His eyes widened and he was dumbfounded.

"How can there be a ship here?"

He just felt incredible.

"Should I get on board and take a look?"

His eyes flashed, and then he decided that he shouldn't have boarded the ship to find out.

"It's very unreasonable for this ship to appear here for no reason! Besides, I didn't see anyone on it!"

He saw a soft glow floating on that ship, and after he looked closely, he felt that those soft lights should be released by the Night Pearl.

He took a deep breath and followed closely behind the ship.

He saw the ship stop for a moment towards the exit of the underpass, then leave, returning the way it came.

When Xu Hai saw this, he felt that the ship was full of mystery.

He lurked near it, following closely.

He followed it for dozens of miles, and finally saw it land on a building that resembled a dock.

Moreover, he saw that there were more than a dozen similar ships in that place that resembled a dock.

"What the hell is this place?"

He looked around for a moment, then decided to go around the left side of the dock-like building.

A quarter of an hour later, he had infiltrated the dock-like building.

After entering inside, he was shocked to find that the Yuan Force in his body was strongly suppressed.

"It's so strong Yuan Force suppression here!"

His complexion changed dramatically, and his heart beat violently.

He hurriedly ran the exercises and transferred the Yuan Force in his body to Ning Dan Zheng

In Xu Zhenyang's memory, there is a way to deal with the suppression of Yuan Li.

Now he used Xu Zhenyang's response to the suppression of Yuan Li to protect himself to the greatest extent.

"What the hell is this place, and why is it so weird?"

Xu Hai only felt that the place he was going to now was full of all kinds of weirdness that he couldn't understand.
