Yin Xu’s pupils contracted slightly, and he waved his hand.

A point of black light flashed in front of him, rapidly growing larger at a visible speed, transforming into a black circular mirror. It spun incessantly, emitting strange black rays of light that swept outwards.

Wherever the black light passed, illusory figures appeared in the void, walking back and forth or flying past. They appeared to be people who had passed through this place in the past.

Some of these figures were clear, while others were extremely blurred.

Among the figures, the figures of Han Li and the others appeared, extremely clear, rapidly flying towards a small path.

"Chase!" Yin Xu and Gui Mu immediately flew after them.

……

Deep within the black palace, Han Li and his group were advancing rapidly.

The scenery on both sides retreated quickly, revealing a series of continuous palace walls, pavilions, and towers, resembling an imperial city.

The group dared not fly in the sky, but instead stuck close to the ground, flying forward between the buildings.

As they went deeper, the light nearby grew dimmer and dimmer, and faint wisps of black mist lingered in the void. Anything beyond thirty or forty zhang was blurry and indistinct, and their spiritual sense could not stray too far from their bodies.

At this time, with the eyesight of Hu San and the others, they could only barely see beyond a hundred zhang.

Han Li’s eyes shot out two purple lights, urging the Nine Serenities Devil Eyes to look ahead. He could still make out the road ahead, but only to a distance of about three hundred zhang.

In addition, there seemed to be some indescribable spatial pressure in the void. Although it was not enough to harm Han Li and the others, their forward speed was greatly reduced.

"What the hell is this place? I feel a little strange. Fellow Daoist Tihun, have you discovered anything?" Hu San couldn't help but say while running.

"No, this is my first time here too," Tihun shook her head.

"Since intense fighting is prohibited here, it's very beneficial to us. Why don't we have a big battle with the pursuers behind us?" Hu San said again.

"No, although there is such a rule here, once we fight to the death, the other party's Grand Luo cultivators may not abide by it. The risk is too great. We can't bet our hopes on them. Even if we fight, we must find a place that is absolutely favorable to us," Shi Chuankong immediately shook his head in rejection.

"That makes sense," Hu San nodded.

"Eh!"

While moving forward, Han Li looked around and suddenly let out a soft exclamation.

"Fellow Daoist Li, have you discovered something?" Shi Chuankong looked over.

"No, I just think the layout of the surrounding palaces is a bit mysterious, like some kind of large formation. Perhaps the pressure in the space is related to this..." Han Li said thoughtfully.

The layout of the surrounding palaces, pavilions, and other buildings seemed ordinary, but in fact, it implied a certain pattern. Moreover, these buildings were all engraved with many restriction runes, and there was an indescribable connection between them.

"Speaking of which, it seems that's indeed the case. It seems that this place is indeed an important forbidden area, but it's strange that there isn't a single person guarding it," Baili Yan nodded.

"Not good, Gui Mu and the others are catching up, and they're very fast!" Tihun's expression suddenly changed, and she said.

The others were startled when they heard this. Without asking how Tihun sensed the situation behind them, they immediately accelerated their forward speed.

However, their cultivation base was far from that of Gui Mu and the others, and with the spatial pressure in the void, although they tried their best, the distance between the two sides continued to shrink.

"There's a passage leading to the underground ahead, and there's a strange aura inside. Do you want to go in?" Han Li looked in a certain direction ahead and suddenly said.

"Go in, take a gamble!" Shi Chuankong said through gritted teeth.

"What could be more troublesome inside than the two guys chasing us from behind?" Hu San grinned.

"That's right. Now that we've come to this point, let's go in and see. As things stand, there is only a glimmer of hope if we put ourselves in a desperate situation," Baili Yan also hardened his heart.

Tihun naturally followed Han Li's lead without a second thought.

"Follow me," Han Li slightly changed direction and flew towards the left front.

The others immediately followed, instantly arriving next to a huge artificial mountain hundreds of zhang high. There was a cave entrance at the bottom of the artificial mountain.

The entrance was quite large, more than three or four zhang high. The rocks on both sides inside were light white, faintly revealing faint light, making the light inside quite bright.

The white light flickered, making it quite beautiful.

Inside the cave was a long passage, which seemed to lead to the underground. A warm air current rushed from inside, the air current was slightly pungent, seeming to be the smell of sulfur and magma.

The group did not hesitate and immediately flew away, fleeing into the depths.

Just as the figures of Han Li and the others disappeared into the underground passage, figures flashed outside the cave, revealing the figures of Gui Mu and Yin Xu.

"Damn it, they actually escaped inside. Do these people know the secrets here? Impossible, only the Domain Lord and Grand Luo like us know these things, even You Luo doesn't know!" Gui Mu said with an ugly expression.

"Stop talking nonsense, go in and catch them immediately," Yin Xu coldly snorted impatiently, and his figure flew into the cave entrance.

Gui Mu's expression turned cold, and a trace of anger flashed in his eyes.

At this moment, the white civet cat in his arms looked up at its master and let out a soft cry.

Gui Mu stroked the civet cat's head, took a deep breath, and his expression had recovered. His figure also flew in.

Han Li and the others advanced with all their strength along the passage. There was only one passage, and it rarely curved. Moreover, the light inside the cave became brighter as they went deeper. The group's advance was quite smooth.

However, there was no joy on their faces. Such a straight road was more suitable for the pursuers behind them.

The group's expressions suddenly changed completely, and their fleeing figures stopped.

The passage ahead suddenly became larger, and a huge square space emerged, resembling a giant hall. It was about thirty or forty zhang in size.

However, they had also reached the end here. There was only a tightly closed giant stone door on the innermost wall of the giant hall, and the spatial pressure in the void had reached a rather frightening level.

The stone door was engraved with dense curse patterns, emitting several different colors of light. Each light emitted a powerful aura fluctuation, obviously all extremely powerful restrictions. Among them, a silver light was particularly dazzling, forming a silver light curtain covering the stone door.

Strands of silver light, like water waves, undulated and flickered on the light curtain, appearing quite gorgeous.

Similar array patterns were also engraved on the other walls around the giant hall, connected to the restrictions on the stone door, forming some kind of special restriction.

The crowd looked around, as if they all thought of something, and their expressions instantly became extremely ugly.

Hu San gritted his teeth, raised his hand and waved, and a dazzling white light shot out. It was a cone-shaped immortal artifact about a foot long, snow-white all over.

Judging from the aura it emitted, it was at least a Rank 7.

Strands of white electric arcs were wrapped around the white cone, making bursts of thunderous rumbling sounds. It instantly turned into a blurry white phantom and stabbed fiercely at the stone door.

At the moment of impending contact, Hu San urged the magic formula in his hand and whispered, "Hurry!"

As soon as he finished speaking, a deafening thunderclap exploded!

Then, a round of dazzling, scorching-white sun emerged, and suddenly burst open. Countless dazzling white electric arcs shot out in all directions, submerging the stone door inside, making it impossible to see the situation inside for a while.

Seeing this scene, Han Li's eyes flashed with purple light, and his brows furrowed.

The dazzling, scorching-white sun faded quickly, soon revealing the situation inside.

It could be seen that the white cone-shaped immortal artifact had stabbed on the stone door. The several kinds of restriction lights on the door flickered slightly, but not a single trace appeared.

Seeing this scene, the crowd's expressions changed again.

The power of the white cone was obvious to all, but it could not leave a single trace on this stone door.

"I'm sorry for bringing everyone to this kind of place. It seems that the trouble is big," Han Li smiled wryly and said.

"Fellow Daoist Li, why blame yourself? Coming in here was a decision made together by all of us, and we will naturally bear the consequences together. Moreover, it may not be a good thing to continue running away like this. Since we are caught up, there is no way, let's fight to the death," Hu San waved his hand to recall the white cone and hovered over his head, smiling faintly, and turned to look at the way he came.

"That's right, those people don't dare to engage in intense fighting here, but we don't have this concern, and we may not lose," Baili Yan also laughed loudly and turned around.

A sharp light flashed in Han Li's eyes, and he also turned to look in the direction he came from, and golden light faintly appeared on his body.

Tihun glanced at Han Li and stood beside him.

Shi Chuankong did not follow Han Li and the others to meet the enemy, but flew to the stone door and waved his hand with a magic formula.

A flash of silver light appeared in front of him, and a silver ancient mirror appeared. With a flash of light, it spewed out a silver light, shining on the stone door.

The restrictions on the stone door immediately fluctuated, especially the silver light curtain, which trembled endlessly.

"Fellow Daoist Shi, could it be that you can crack these restrictions?" Baili Yan asked with joy in his eyes.

"The restrictions here are very clever. Shi is not sure that he can break them, and I need to spend some time to study them carefully," Shi Chuankong shook his head, and said ambiguously.

"That's good, Brother Shi, feel free to study it with peace of mind. We will deal with the pursuers and try our best to buy you time," Hu San laughed loudly and said.

Shi Chuankong nodded, then ignored the others and concentrated on studying the restrictions on the stone door.

Han Li turned his head and glanced at Shi Chuankong, quickly retracted his gaze, and looked towards the passage ahead.

"They're here!" Tihun suddenly said softly.

Figures flashed in the passage ahead, revealing the figures of Gui Mu and Yin Xu.

"A few rats, you run very fast!" Yin Xu glanced around the hall, his eyes relaxed slightly, and he said coldly.

"If you know what's good for you..." Gui Mu also sneered, just about to say something.

"Boom"

A thunderous roar exploded, but it was the white cone above Hu San's head that shot out with white electric light wrapped around its surface, shooting towards where Gui Mu was.

"If you want to fight, then fight, why bother talking nonsense!"
