"Buzz!"

Numerous ripples suddenly appeared within the originally calm Mysterious Black Yin Mountain when this Soul Power light beam smashed into the seal. Low muffled sound was emitted from the sky and wisps of black devilish aura similar to small black snakes were emitted.

When everyone saw this black demonic aura, there were quite a few changes in their expressions. Immediately, their bodies carefully withdrew a little.

Finally, it was accompanied by a creaking sound as the seal at the entrance of the cave was broken. At that spot, after the black Qi had scattered, a thick stone door that was a couple hundred feet long slowly opened the moment the seal was broken.

The moment the stone door opened, they took in a deep breath and stared intently at the opening stone door. There might be a scent that made their hearts palpitate, but they were well aware of what treasure was inside.

Boom!

The opened cave was just like an explosion that had been ignited. In an instant, it caused the eyes of countless number of experts to turn red with envy. The rushing wind sound that filled the sky appeared at the same time.

Xia Hun Wu felt the sky filled with human figures and his expression slightly froze. Even before reaching a place where he could suppress the Habitat Devil Sin, there would still be so many people. It was just that he did not know if the Devil Sin was still alive.

"Brat, later when you enter, you must be careful. The life force of the Black Demon Clan is extremely tenacious. They will not be so easily suppressed."

Old Man Mu's eyes narrowed slightly and he spoke softly to Xia Hewwu. Then, he quickly turned into an afterimage as he swept through Xia Hun Wu's body. Without Old Man Mu's support, the Scarlet Dragon Tiger would once again turn into a tiger cub.

He immediately placed the Scarlet Dragon Tiger into his embrace and with a tap of his feet, he rushed into the cave at the mountain entrance.

The moment he rushed into the cave entrance, the black aura made Xia Hun Wu extremely uncomfortable. He could feel the corrosive intent from the black aura and immediately, waves of Azure Sky Flames started to spread out, resisting the black aura's corrosion.

When he opened his eyes again, the scene in front of him was immediately reflected in Xia Hun Wu's eyes. A brief moment of absent-mindedness could be seen in his eyes.

"This... "There's actually another small world here!"

On this land, there were numerous palaces. However, most of these palaces had already been turned into ruins. However, from the looks of these ruins, it was still clear just how grand and majestic this small world was back then.

Right now, there was a black and white light appearing on this piece of land. A kind of bald and useless aura filled this small world. The desolation within it was especially obvious.

Evidently, it had been a long time since there was a chance for life in this small world.

Although this small world was not as large as the Five Yuan World, it still caused Xia Hun Wu to be slightly startled. Clearly, he did not expect that there was such a scene within the cave. From the looks of it, this was a fight between a sect and the Black Demon Sect, and not a fight between a supreme expert and the Habitat Devil Thief.

"Did we get screwed by that roll of kraft paper?" Xia Hun Wu muttered to himself.

"It seems that this Venerable One is no ordinary Venerable One. He must be at least a Venerable One in the dead realm. And that piece of kraft paper was obviously deliberately released by the Black Demon Sect." At this moment, Elder Mu's voice rang out from within Xia Hun Wu's heart.

"Then should we return it or keep it?" Hearing this, Xia Hun Wu's face became gloomy. If this piece of kraft paper was deliberately set free by the Black Demon, then this must be a plot of the Black Demon. With his strength, he still wasn't strong enough to contend with the Black Demon.

"Let's take a look first. Even the twelve super empires and the Soul Region have sent people over. It is likely that there are quite a number of treasures within. As for the black demon, if something is wrong, we will immediately flee." Elder Mu couldn't help but comment when he saw Xia Hun Wu's intention to retreat.

"Alright, since we're already here, let's try our luck." Xia Hun Wu lightly nodded his head. After his voice sounded out, his body flew into the air as his eyes continuously swept across the pile of ruins below him.

As he advanced in this manner, Xia Hun Wu was also able to see the traces left behind by the battle between the Venerable Martial Saint and the Black Demon Sect. It seems like a soul-stirring battle had indeed erupted at that place back then.

"Could it be that the Black Demon Sect was hidden in this small world, and the Venerable Martial Reverend caused this great war?"

Although he did not know the origin of this Venerable Warrior Wu Dou, it was likely that he would be able to fight with the Black Demon Sect at such a time. His strength was quite tyrannical, after all, only the three sects and four sects would dare to fight with the Black Demon Sect at such a time.

As this thought flashed in Xia Hun Wu's mind, he continued to scan his surroundings. Suddenly, a thought struck him. The scene before his eyes seemed to have a sense of familiarity …

This spiritual energy … It seems to be the Divine Inscriptionist's … This aura is the Essence Sky Seal?

Xia Hun Wu's expression instantly turned serious. He finally understood why there was a familiar feeling coming from this place. This was because the aura here was similar to the aura that had emerged from the Devouring Sky Seal in the Spirit Emblem Tower earlier.

Moreover, with the strength of this spiritual force, it would definitely be one of the eight source seals. During the ancient era, the Black Demon Sect had once hunted down and killed a Heavenly Seal Master with eight source seals?

Xia Hun Wu's figure that was hovering in the air slowly stopped. A trace of astonishment rose in his eyes at this moment. In his heart, he said: "Old Mu!"

"Yo, not bad kid. You discovered him so early …" Old man Mu's voice was very calm, but at this moment, it was filled with a rare sense of vicissitudes.

"Is it really those Black Demon's doing?" Xia Hun Wu asked as he exhaled deeply.

"More or less …" I am not too sure about the specifics, after all the two devils possess too much power. Even if they had gathered eight Source Heavenly Seals, they would only barely be able to seal them. And after those almighty beings sealed the Black Demon and Black Demon, the Black Demon Sect would also completely disappear without a trace. "

"Although the vitality of the Black Demon Sect is extremely tenacious, eight Heavenly Seal Essences are their mortal enemies. And the Heavenly Seal Masters who possess eight Heavenly Seal Essences have already been annihilated by the Black Demon Clan by no less than ten.
