“Now that things have come to this, I won't hide anything from you all. I do know something about the seventh level of this Time Tower. You've all probably realized along the way that this Time Tower is a prison, holding many prisoners. The seventh level is the same, suppressing an unparalleled demon." Lei Yuce withdrew his gaze from Xiong Shan and said slowly.

"An unparalleled demon?" Han Li raised an eyebrow.

"That's right, this unparalleled demon is far from comparable to the prisoners we encountered earlier," Lei Yuce added.

"The prisoners we encountered earlier were already at the Grand Luo level. Could this unparalleled demon be a Dao Ancestor?" Lan Yan scoffed, unconvinced.

"My Tongtian Sword Sect's founding ancestor participated in the sealing of this demon. According to the records left by the ancestor, even if that demon isn't a Dao Ancestor, it's not far off," Lei Yuce said with a solemn expression.

Seeing Lei Yuce's expression, Lan Yan also put away her smile.

"Your sect's ancestor has been here before? This Time Tower should have been built by Immortal Sovereign Taisui. Could it be that your sect's ancestor knew Immortal Sovereign Taisui?" Han Li's eyes narrowed as he asked.

"Regarding this, the sect's records don't mention it, and I'm not sure," Lei Yuce glanced at Han Li and shook his head.

Han Li remained silent, but he was skeptical of Lei Yuce's words, unsure whether he was deliberately withholding information or genuinely didn't know.

"Lei Daoyou, is the demon you're talking about the Black Heaven Demon God who once blood-sacrificed the entire Jin Yuan Immortal Domain?" Su Anqian suddenly interjected.

"That's right, it's this demon. Su Daoyou must have a deep impression of this demon, right?" Lei Yuce looked deeply at Su Anqian and said.

"During that great calamity, my Tianshui Sect's records naturally also have accounts of it," Su Anqian nodded, her face slightly pale.

"What are the two of you talking about? Could you also let us know?" Han Li asked.

"You Daoyou are not from the Jin Yuan Immortal Domain, so you don't know about this matter. Many millennia ago, tracing back to the time of the war with the Demon Realm, we in the Jin Yuan Immortal Domain experienced a great calamity. A Demon Race powerhouse named Black Heaven Demon God descended upon the Jin Yuan Immortal Domain and launched an unparalleled demon formation, blood-sacrificing the entire Jin Yuan Immortal Domain. At that time, more than half of the living beings in the Jin Yuan Immortal Domain died in that demon formation. Later, a Heavenly Court Dao Ancestor took action to break that demon formation. This matter was a great calamity for the Jin Yuan Immortal Domain, causing extremely severe damage. It can be said that it hasn't recovered even now. The name Black Heaven Demon God is also a taboo in the Jin Yuan Immortal Domain," Su Anqian sighed and said.

"I see," Han Li nodded slowly, his gaze turning towards the front of the cave, his mind racing.

The demon here is actually related to the Immortal-Demon War of that year. I wonder what the relationship is with the people of the Nightfall Dynasty?

"Su Xianzi is absolutely right. Actually, the emergence of Immortal Abode Taisui this time isn't accidental. According to the sect's records, it's likely that the demon is attacking the seal, causing the immortal abode to appear. My purpose with Wen Zhong's coming here is to reinforce the seal. The great formation sealing that demon has five formation eyes, arranged according to Metal, Wood, Water, Fire, and Earth. Under each formation eye are also sealed some demons from the Demon Realm. This golden altar here is the Metal formation eye," Lei Yuce continued.

"The golden altar has now collapsed, meaning one of the formation eyes has been destroyed?" Lan Yan said with some unease.

The others also became solemn.

"That's right. Originally, as long as the five formation eyes were unharmed, the Black Heaven Demon God would never have been able to escape. Unfortunately, now the Metal formation eye has been destroyed. If the other formation eyes are destroyed, the Black Heaven Demon God is likely to break free from the seal. At that time, not only will we have no chance of survival, but the entire Jin Yuan Immortal Domain will once again fall into calamity. Therefore, you must be cautious in your actions next, and you must not damage any other formation eyes," Lei Yuce said with an extremely solemn expression.

Hearing this, the others nodded.

"Then what do we do next? Do we continue forward?" Lan Yan asked.

"That's right. But before we go, I'll try to repair this formation here. This formation is the key to the Metal formation eye. Although it's damaged, its essence hasn't completely dissipated. If it can be repaired, it might still be able to play some role," Lei Yuce pondered for a moment, then said.

Saying that, he bent down to examine the formation on the ground.

Wen Zhong also stepped forward to help. After discussing it, the two quickly began to act, taking out various formation tools and starting to repair the formation.

Han Li and the others were not familiar with the formation on the ground and couldn't help, so they walked to the side and continued to meditate and cultivate.

In the blink of an eye, more than half a day passed. While Han Li and the others were cultivating, a strong formation fluctuation came, and everyone hurriedly stood up.

They saw that the golden formation on the ground had been repaired. At this moment, it was buzzing and operating, and a thick golden light rose from the formation, disappearing into the stone wall of the cave ceiling.

Lei Yuce continuously formed hand seals, and the golden formation slowly stopped, and the golden beam of light quickly dissipated.

"Fortunately, not much of the formation was damaged, and it was barely repaired," Lei Yuce said with a smile on his face, nodding.

"Then can the repaired formation function?" Lan Yan seemed quite fearful of the Black Heaven Demon God and hurriedly asked.

"I don't know about that. Let's hope it's useful," Lei Yuce said after a moment of silence.

Hearing this, the others looked at each other, and no one spoke for a moment.

"Let's go, we've been delayed here for a long time, let's move forward quickly," Lei Yuce said, then waved his hand and sent out a golden light, rolling up the nearby stones and covering them on the golden formation.

Everyone's injuries had mostly recovered by now, and they were already impatient to stay here, so they quickly continued forward.

…

Following the mountain cave all the way out, the group walked for a long time and finally exited the cave.

Outside the cave was a platform with an area of ​​only a few hundred zhang. The ground was rocky, seemingly halfway up a huge mountain.

Han Li and others came to the edge of the platform and looked around, but saw gray mist swirling in the void, and they couldn't see anything at all.

Xiong Shan stared into the distance for a while, frowned, and suddenly raised the golden long sword in his hand and slashed towards the distant void.

Only a sword sound was heard, and a huge golden sword light burst out instantly.

Looking at the strength and speed of the sword, it should have instantly split the void and traveled hundreds of miles, but to everyone's surprise, the sword light only flew out a few hundred zhang before it seemed to hit a high wall, and with a bang, it disintegrated.

"Sure enough, there are restrictions..." Xiong Shan muttered to himself upon seeing this.

"There's no need for you to try, the restrictions outside this mountain are related to the foundation of the entire Time Tower, unless someone has the ability to smash the entire Time Tower, otherwise don't think about breaking through by force," Lei Yuce reminded upon seeing this.

Hearing this, Han Li's divine sense spread out, and his divine sense began to probe in all directions.

However, his brows quickly furrowed. The restrictions around him were also very strict on the imprisonment of divine sense. With the strength of his divine sense, he could not spread too far.

Seeing this, everyone had no other choice but to swoop out of the cliff and fly upwards along the mountain peak.

After flying nearly a thousand zhang, Jiao San suddenly gave a light "Eh" and stopped first.

Seeing this, everyone stopped immediately and looked towards the mountain in the direction of her gaze, and saw that another cliff platform had appeared there, with a man-made stone ladder that stretched upwards along the mountain.

"Let's go, let's go and take a look." Lei Yuce called out and flew towards that side first.

Wen Zhong and Su Anqian followed up first, and Han Li and the others followed closely behind and flew away.

Han Li landed on the cliff, glanced around, and found that there were no caves around, only that stone ladder.

So everyone went up the stone steps one after another and rushed towards the top of the mountain.

The stone steps were steep and winding, taking everyone all the way up. After traveling hundreds of zhang, they arrived at another larger platform, where a water-blue double-eaved hall appeared, built on the mountainside, with flying eaves, looking very simple.

In front of the main hall was a square with an area of ​​several hundred zhang. The ground looked like a lake, reflecting mirror-like light, and there seemed to be water vapor rising on it, filled with a light blue water mist, making it unclear.

Lan Yuanzi glanced at the water mist, frowned slightly, and a hint of doubt flashed in his eyes.

"Brother, what's wrong?" Lan Yan asked suspiciously.

"Here looks sparkling with water, and there are faint fluctuations of water attribute laws, but the water vapor is not as thick as seen with the naked eye. I think... this is mostly a water attribute illusion formation." Lan Yuanzi pondered.

"Water attribute illusion formation?" Hearing this, Han Li couldn't help frowning.

A flash of purple light flashed in his eyes, and the Nine Nether Devil Eye Divine Ability started to operate, carefully looking inside.

Under the Devil Eye, one could see clusters of water vapor vortexes condensing and flowing in the water mist, attracting and resisting each other, forming a very special aura fluctuation.

After watching for a while, Han Li felt that the corners of his eyes were a little wet, as if water vapor was invading. While he was wondering, when he looked around again, he suddenly found that Lei Yuce and Jiao San and all the others were gone.

He smiled bitterly in his heart and felt a little helpless. It turned out that when they crossed the last stone step and came to the edge of the cliff, they had already entered the illusion formation.

Han Li's eyes narrowed, and he began to fully operate the Refining God Technique, trying to forcibly break through the obstacles in front of him with the powerful power of his divine sense.

However, it would have been better if he hadn't operated it. Once he operated it, the surrounding scenery immediately changed.

I saw that the water vapor vortexes that I had just seen seemed to be stimulated by something, and they began to spin violently, pulling and colliding with each other, looking like a series of hurricanes collided together.

As soon as Han Li had such an idea in his mind, he suddenly heard the sound of waves all around, and his figure actually appeared on a dark sea.
