The Eight Great Demon Gods of the Demon God Mountain at this moment also saw the situation on the distant mountain peak. One by one, they looked at the remnant souls of the Outer Heaven Demons emerging from the Ancient Battlefield, their expressions turning grim.

Cang Yue sighed, "I didn’t expect that the great war tens of thousands of years ago didn’t completely annihilate those creatures from beyond; now they’ve returned."

He quickly said to Chen Nan, "Chen Nan, we old folks will block these remnant souls of the Outer Heaven Demons. You must leave here quickly."

Chen Nan’s face changed, "What about Dragon Emperor, senior?"

He desperately needed the Origin Power of the Heavenly People Clan’s supreme power, but he was equally worried about the safety of the Dragon Emperor. The Dragon Emperor had spent thousands of years to complete the great work of revival, and now, at the final juncture, if something went wrong, it would all be for naught.

Even if the Origin Power is lost, it can be sought again outside the domain from the Heavenly People Clan’s supreme power, but if the Dragon Emperor fails to revive this time, it might take thousands of years again. By then, the Four Extremes World could experience other changes, perhaps becoming drastically different.

Cang Yue shook his head, "The Dragon Emperor is powerful and shouldn’t be in danger. His Dragon Soul has long recovered, what’s left is only the restoration of his physical form, which just requires a bit of time. You should go quickly, these Outer Heaven Demons may just be remnant souls, but they’re definitely not easy to deal with."

At this moment, an ancient voice echoed throughout the Panlong Star Domain from within the Stone Coffin, "Chen Nan, you should leave, this matter doesn’t need your involvement. All of today’s events are the result of the karmic cycle planted by this seat over tens of thousands of years, and cannot be avoided until the shackles of the Heavenly Dao are broken."

Countless remnant souls of the Outer Heaven Demons appeared, immediately causing chaos, with lightning flashing and thunder rumbling across the entire Panlong Star Domain’s sky.

These remnant souls of the demons directly triggered the Heavenly Dao’s punishment in the Four Extremes World.

"Heh heh, there’s a powerful Ancient Divine Dragon in that Stone Coffin trying to revive, what a powerful aura; if we absorb its energy, it would be enough to restore our bodies."

Among these remnant souls of the demons, the leading soul’s eyes shone with greed, as if ready to devour at any moment.

"Dragon Emperor, senior, if these Ancient Demon God remnant souls seize your energy, then the entire Four Extremes World will fall. Today, whether for you or for myself, for my friends, I have no reason to leave."

Chen Nan was truly enraged; at this moment, he absolutely could not leave.

Taking a step back would be nothing, but stepping back could lead to a thousand more retreats in the future, and that was not Chen Nan. He could never coexist with these Outer Heaven Demons.

The only solution was to eliminate them all within the Panlong Star Domain since they sought death anyway, it’d be perfect to catch them all in one go.

"Cang Yue, senior, let me help you kill the enemies."

A ruthless glint flashed in Chen Nan’s eyes, and he never felt any mercy towards these invaders.

As soon as Chen Nan said this, the remnant souls of the Heavenly Demon God Demon all revealed ferocious looks, baring their teeth: "Kid, you’re just a mere Heavenly Monarch Realm, yet you dare to meddle in what your grandfathers are doing, you’re looking for death."

These Outer Heaven Demons were fearless supreme experts in life, if not for suppression by the Four Extremes World’s laws, they would have occupied the Four Extremes World long ago during the Ancient War.

The strength of the Outer Heaven Demons was so formidable that even the Heavenly Dao of the Four Extremes World couldn’t contain them.

Compared to the Heavenly People Clan, they were even more terrifying. If their powers weren’t suppressed upon arrival, equating them to the supreme experts of the Human Clan, the ancient experts of the Four Extremes World would not be able to withstand them.

Hearing their words, Chen Nan wasn’t angry; instead, he retorted with a smirk, "Just a bunch of remnant souls dare to be so arrogant, do you really think the Four Extremes World is without people, the Mortal World is without people?"

These remnant souls’ expressions changed drastically, gritting their teeth, always ready to pounce and devour Chen Nan.

Chen Nan chuckled coldly, "Even if you revive, you lack the power of your prime. Don’t even mention asking our Human Clan’s supreme to act, I, a mere small Heavenly Monarch, can make you soul scattered and completely obliterated."

"Damn native ant, what gives you such audacity?"

The leading remnant soul rolled its eyes, staring at Chen Nan, trying to discern the source of his confidence.

"What gives me the right? It’s not like I haven’t been to the Ancient God Demon Battlefield. Not only did I go, but I also killed two of you Outer Heaven Demons incidentally."

As he said this, he suddenly seemed to recall something, slapping his forehead, with an ’almost forgot’ expression, laughed, "Oh right, there was a guy, the Slayer Demon Lord, who was killed by my Human Clan’s supreme and refined into my avatar. Want to see it?"

He laughed heartily and instantly summoned the Demon Lord Avatar.

As soon as the Demon Lord Avatar appeared, the remnant souls of the Outer Heaven Demons were all visibly shocked, able to discern the avatar’s power.

Unexpectedly, such a supreme-powerful avatar was refined by a junior, no wonder he was so arrogant.

Among them, some even recognized Slayer Demon Lord, whose strength among supremos was exceptionally formidable, yet he was slain.

The remnant souls of these Outer Heaven Demons immediately became somewhat uneasy, hesitating, as they weren’t released from the Ancient God Demon Battlefield just to throw away their lives.

A sly glint flashed in Chen Nan’s eyes. Now was the critical moment for the Dragon Emperor’s revival, and any time he could stall was beneficial.

Seeing the remnant souls of the Outer Heaven Demons seemingly hesitating, Chen Nan’s lips curled into a smile of a plot well-executed. 𝒻𝘳ℯℯ𝑤ℯ𝒷𝘯ℴ𝓋ℯ𝘭.𝑐ℴ𝑚

Just as he was about to telepathically communicate with the Dragon Emperor, he suddenly saw a Dragon Claw reach out from the Stone Coffin, carrying a blue-white spherical object flying toward his hand.

This spherical object contained terrifying energy, instinctively grabbed by Chen Nan.

"Chen Nan, this tribulation isn’t as simple as you think, you must leave quickly. This is the Origin Power of the World seized from the supreme of the Heavenly People Clan. Take it to the Ancient God Star to that girl, and she will be cured."

Seeing Chen Nan grasp that mass of Origin Power, the Dragon Emperor was about to throw him out when suddenly, a deeply displeased voice came from the distant void.

"Dragon Emperor, why put on such an act? Even if Chen Nan is here today, I won’t make things difficult for him. Do you have to be the world’s saint? What do I do?"

A voice, also carrying a sense of deep age yet full of boundless anger, exploded in the void, instantly invigorating the remnant souls of these Outer Heaven Demons.

The remnant souls, initially bluffed by Chen Nan, now charged toward the Dragon Emperor’s Stone Coffin. With their arrival, the range of heavenly thunder and lightning above the Panlong Star Domain also extended to the vicinity of the Dragon Emperor’s Stone Coffin.

Just as the myriad of demon remnant souls appeared, Chen Nan thought first about the safety of the Nine Nether Evil Emperor on the Ancient God Demon Battlefield. At this moment, seeing the Nine Nether Evil Emperor in the void, his face turned extremely grim.
