Ye Tianfan and the others saw a light ahead, and quickly dimmed their magical treasures to the lowest brightness.

The presence of light ahead indicated people were there. If someone was around and their magical treasures were still on, as long as the enemy wasn't blind, they would know that someone was there.

Ye Tianfan and the others couldn't expose themselves right now; otherwise, they might not make it out of the Polo Cave, especially since they couldn't be sure if there were experts above Qian Yuan's level among them.

Just as everyone thought the enemy hadn't discovered them, a sudden change occurred. A ghostly wailing howl echoed around them, and various colors of light appeared in the darkness, rushing toward Ye Tianfan and the others.

Ye Tianfan and his group were startled, but fortunately, they had only dimmed their magical treasures instead of retracting them to be safe. Thus, the defense capabilities remained intact, blocking the magical treasures shot from all directions.

Just as the group heaved a sigh of relief seeing these magical treasures blocked outside, the ghostly wailing sound grew increasingly piercing.

"Damn, it's a sonic magical treasure. Everyone, cover your ears," Yun Tian, the eldest brother, advised the group insightfully. However, even with their ears covered, they would still be affected. After all, sound penetrates not only through the ears but can enter anywhere in the body, and don't forget sound can travel through vibrations. As long as the sonic waves emitted by the magical treasure hit any part of the body, they can transmit tiny vibrations to the auditory nerves to affect Ye Tianfan and his group.

The ghostly wailing sound made Ye Tianfan and the others feel dizzy and unsteady, while Ma Feiyun, driven by frustration, almost rushed out of the protection circle of the Qilin Seal. Fortunately, Yun Tian stopped him; otherwise, it would have been a senseless loss.

"Don't be reckless! They want us to rush out of the magical protection to eliminate us. Don't fall into their trap," Yun Tian shouted at Ma Feiyun, also reminding Bai Feng and Ye Tianfan.

But as Ye Tianfan and the others were feeling dizzy and extremely restless, various colors of magical treasures launched another wave of attacks from the darkness, fiercely striking Ye Tianfan's Xuanhuang Tower.

"Be careful, they're trying to take us down one by one!" Yun Tian quickly saw through the Demon Sect individuals' intentions. But Ye Tianfan also realized it without Yun Tian's reminder. It was painfully obvious.

Ye Tianfan, enduring the dizziness, formed a few hand seals. The Xuanhuang Tower shone brilliantly as Ye Tianfan inside it took deep breaths and vigilantly observed the surroundings.

It was clear Ye Tianfan had also blocked out the sound. While this meant he wouldn't be harmed anymore, he also couldn't hear Yun Tian and the others. Inside the tower, Ye Tianfan was as if isolated from the world.

The surroundings were no longer dark, illuminated as bright as day by Ye Tianfan's Xuanhuang Tower.

All around were countless people, with various magical treasures floating beside them. It seemed the treasures attacking earlier belonged to them.

After Ye Tianfan isolated the outside noise, Yun Tian and Bai Feng also pain-stakingly performed hand seals to block the outside. However, this meant they couldn't hear each other and could barely see one another due to the blinding light of the magical treasures.

However, among the crowd, Ye Tianfan noticed a person playing a bizarre instrument. This instrument seemed strange because Ye Tianfan had never seen anything like it. Not only did it look odd, but the way it was played was also exaggerated.

Nevertheless, Ye Tianfan and the others were sure that the ghostly wailing sound originated from this individual.

Ye Tianfan nodded at Yun Tian, although Yun Tian might not see it due to the blinding light of the Xuanhuang Tower. Ye Tianfan then unleashed the Fire Lotus Sword, directly attacking the person.

That person leapt to the side, and the Fire Lotus Sword stabbed the individual behind him instead.

After retrieving the Fire Lotus Sword, Ye Tianfan prepared to attack again but saw the stabbed person turn around, swinging a fist and a short axe from his waist toward the instrument player.

The stabbed person cursed, "You bastard, you dare dodge? Don't you know that by dodging, you made me take the hit? Since I took the sword for you, now you'll pay back."

The instrument player, not expecting to dodge an enemy's sword but then get punched and axed by his own, began cursing at his attacker with vile words before dying, causing his attacker to retaliate by chopping him again.

"Still dare to curse me," the attacker said, delivering several more chops.

What is going on?

Ye Tianfan was baffled, instinctively turning to look at Yun Tian. The magical treasure light had dimmed significantly now. Keeping it at full brightness was extremely taxing on spiritual power; despite being unable to hear, they could see confusion in each other's eyes.

After shooting an arrow, missing, and then witnessing the enemy helping finish the job, Ye Tianfan never expected such a scenario. The Demon Sect truly lived up to its name; such bizarre occurrences seemed typical.

Since the other side helped with this troublesome magical treasure, Ye Tianfan thought to offer a big "gift" in return.

Ye Tianfan swiftly formed a hand seal and sent a sharp and thin Sword Qi streaking through the crowd from the Fire Lotus Sword.

Those Demon Sect members barely dodged; most of them were sliced in half at the waist where the Sword Qi cut through.

Seeing this, Ye Tianfan exchanged glances with Yun Tian and the others, nodding in unison. What followed was a gruesome slaughter.

After Ye Tianfan and the group dealt with all enemies, they discussed and decided not to inform Yu Shan and the others immediately, opting instead to continue deeper into the cave to see what else lay within.

When Ye Tianfan and the others reached the torch-lit area, they saw a massive stone door.

"It would be great if the Dali Sect were here," Ye Tianfan said upon seeing the heavy stone door.

The other three nodded in agreement.

Nevertheless, they exerted great effort and managed to open the stone door, revealing a shocking sight.

Behind the stone door was nothing but a large pool, nothing else. This giant pool wasn't filled with water, but with a pool of blood.
