The most shocking thing was that the liquid inside that lake turned out to be blood.

At first, those who discovered the lake thought it was just ordinary red water.

However, after repeated confirmations, it was finally recognized as blood, and indeed human blood.

Zhu Ge Hongyun and others, upon receiving the order, entered the area for inspection.

After inspecting, they found that it was genuinely a pool of human blood.

As to where the blood inside the pool came from, they attempted to dive deeper, eventually concluding that the blood was coming from underground.

However, they were unable to go deep beneath the bottom of the lake, as there appeared a powerful Space Crystal Wall, obstructing their advancement.

They tried numerous methods, attempting to break through the Space Crystal Wall, but all attempts ultimately failed.

This left Zhu Ge Hongyun and his companions utterly shocked; they never thought that such a bizarre Blood Lake could exist in the world, and beneath it was a Space Crystal Wall they couldn't cross.

Hence, they returned to the Green Cloud Sect to find Duan Gujin.

After listening, Duan Gujin felt that there was definitely something strange about the Blood Lake and the Space Crystal Wall.

Consequently, he rushed over overnight.

Simultaneously, Huang Lingyu from Guanghan Heavenly Palace was scouring through the classics all night, but her subordinates found no relevant records.

"How strange, where did this Blood Lake come from, and how was it formed?"

At that moment, opinions were many and varied.

Various Martial Artists from Qiankun Continent came to the edge of the Blood Pond Lake, trying various methods to find a way to cross the Space Crystal Wall.

But no matter how hard they tried, they ultimately could find no way to breach the Space Crystal Wall.

Upon seeing the Blood Lake, Duan Gujin's expression greatly changed, he furrowed his brow in thought, sensing the presence of the Netherworld Dark Clan within the lake.

Despite the very faint presence, he was certain that the Netherworld Dark Clan had been here before.

He thought that all would be peaceful once the Sky Crossing Demon King was eliminated, but it turned out to be a critical moment as Cao Wentian escaped.

Compared to the Sky Crossing Demon King, Cao Wentian seemed insignificant.

But somehow, during his period of seclusion, Duan Gujin was always restless.

He arrived at the edge of the Blood Lake, and let loose his Divine Sense.

After a while, his eyes suddenly brightened.

"I can now confirm that the energy in this Blood Lake must have been consumed just two or three days ago! It has been over ten days since I eliminated the Sky Crossing Demon King, could it be that Cao Wentian consumed the blood in this lake?"

Duan Gujin quickly inquired with Huang Lingyu, wanting to know if she had any records about the Blood Lake.

Huang Lingyu told him that there were no such records in Guanghan Heavenly Palace.

"How strange, why would such a bizarre Blood Pond appear here?"

Duan Gujin's eyes flickered, a possibility crossed his mind.

"I heard from others before that the Netherworld Dark Clan has a special type of transport passage, which allows them to enter from one Plane to another; because this transport passage resembles a wormhole, it is called the Netherworld Wormhole."

Duan Gujin took a deep breath, his mind whirling. He thought hard, analyzing again and again, finally thinking it highly possible that the passage beneath the Blood Pond was the so-called Netherworld Wormhole.

But he couldn't understand why a Netherworld Wormhole would appear here in Qiankun Continent.

Suddenly, someone ahead let out a scream.

"Everyone, I've discovered something here!"

The crowd ran towards the direction of the voice.

Soon, they saw a smooth rock wall, which revealed some characters.

What baffled everyone the most was that the characters meant that Cao Wentian had left a message, saying if he returned one day, he would definitely exterminate all sects of the Qiankun Continent.

Seeing those words, disdain filled everyone's eyes.

"His return one day? Who is Cao Wentian trying to fool?"

Many Martial Artists thought that this was just a ruse by Cao Wentian, aimed to make people think he had left the Qiankun Continent so they would stop pursuing him.

Huang Lingyu felt it was impossible for Cao Wentian to leave such a threatening message on the rock wall, so she secretly consulted Gujin, wanting to know the meaning behind that sentence.

Gujin immediately shared his speculation with Huang Lingyu to prepare her mentally.

"What? You're saying there's a Netherworld Wormhole below?"

After hearing Gujin's words, Huang Lingyu's complexion slightly changed, and she whispered her question secretly.

"Yes!"

After hearing Gujin's words and reconsidering the words on the rock wall, Huang Lingyu felt everything made sense.

"No wonder Cao Wentian said so, but do you think this could be his cunning plot?"

Huang Lingyu asked dubiously through a secret transmission.

"It's hard to say!"

Gujin furrowed his brows as he examined the rock wall.

After a moment, he finally understood why the words suddenly appeared on the rock wall.

It turned out there was a hidden Array on the rock wall; without careful inspection, it was very difficult to notice any writing.

Although many people from the Qiankun Continent had come here these days, everyone's attention was mostly on the Blood Lake ahead, and only a few would wander around looking for clues.

As the energy inside the hidden Array gradually dissipated, its concealing effect significantly weakened.

Thus, it became quite easy for those nearby to discover it.

"Could all this be Cao Wentian's plot? Or did he actually go through the Netherworld Wormhole below, to another place?"

After pondering for a while, Gujin said to Huang Lingyu: "Palace Master, please deploy more guards to carefully watch this place! Ensure your people are vigilant, and immediately report any activity! I also cannot determine whether this wormhole is real. If it is, Cao Wentian won't return anytime soon! If it's fake, this so-called Netherworld Wormhole will disappear after some time! After a while, we should find a way to destroy this wormhole!"

"Right! We need to find a way to destroy this Netherworld Wormhole!"

Huang Lingyu's eyes lit up as she suddenly understood.

"Let's not overthink! If this is a calamity of the Qiankun Continent, we accept it!"

Gujin said earnestly.

"Right! If this is a disaster for the Qiankun Continent, we accept it too!"

Thus, Huang Lingyu immediately dispatched many people to guard this area, ordering them to report back as soon as they noticed anything.

Meanwhile, Huang Lingyu also asked other sects to send more people to search for Cao Wentian and see if they could locate him.

On the road, Huang Lingyu made a decision.

"Gujin, would you like to enter the trials at Guanghan Heavenly Palace?"
