In that ruined medicine garden, there were thousands of high-grade supreme divine medicine sea abyss demon grasses that were ten meters long and shrouded in a layer of pitch-black seawater.

The City Lord of Xinhai City looked at those top-grade supreme divine elixirs Haiyuan Demon Grass, and his eyes flashed with longing. Even if he wanted to use a thousand low-grade supreme elixirs to shake a high-grade supreme elixir, the sea abyss demon grass, he was willing.

The Superior Supreme Elixir can increase the evolutionary potential of the lower Supreme Demons, allowing them to increase their potential to break through to the Middle Supreme Demons.

Each of those lower supreme demons is a genius against the sky, the son of the world of many big worlds, and the existence of invincible opponents in the world in those big worlds.

The palace master of the Black Moon Palace used to be the lady of heaven in a big world, defeated countless Tianjiao in that big world, dominated the entire world, and then entered the demon world, and went through countless hardships before advancing to the lower level.

However, after the palace master of the Black Moon Palace advanced to the lower level, it was difficult to progress again. Because His evolutionary potential has reached its limit, even if he devours other lower supreme powers, he will not be able to progress.

Only those high-ranking supreme elixirs have the magical power to evolve the potential of the lower-level supreme demons, so it will cause those lower-level supreme demons to go crazy as well.

"There's a powerful ban open here!"

Yang Fan activated the [Insight] skill at once, and his pupils turned into [Insight] magic pupils, and he looked around, and at a glance, he could see that there was an incomparably powerful enchantment opening around the medicine garden.

"However, this barrier is almost impossible for the lower supreme demon to break through. For me, it's a sword thing!"

Yang Fan took a closer look around, and then took out the [Almighty Compass] for heavenly deduction: "I won't have a bad end if I slash this sword!"

The fog churned above the [Almighty Compass], and a confirmation symbol emerged.

Yang Fan held the magic sword transformed into the [Almighty Compass] and slashed towards that enchantment.

A sword light slashed at the barrier, splitting it in two in an instant.

A twisted crack appeared.

Yang Fan threw the Sea Whale Demon into the other side of the crack and probed.

After passing through the crack, the sea whale demon appeared in the medicine garden.

Yang Fan boldly led everyone into the medicine garden.

"You go and find your way!"

Yang Fan gave an order, and the Sea Whale Demon involuntarily turned into a puppet and explored the way ahead.

In the Demon Emperor's cave, I don't know what terrible prohibition is hidden. Yang Fan's Heavenly Skill Attainments were very high, but each of those Demon Emperor powerhouses was incredibly strong. Their methods can't even be resisted by some heavenly powerhouses.

The reason why Yang Fan escaped from the Demon Domain where the Southern Demon Emperor was located was that he didn't dare to underestimate the Southern Demon Emperor. The Giant Heaven Demon Emperor is a supreme demon king, extremely powerful, stealing all over the world, but as soon as he provokes the Southern Demon Emperor, he will be finished immediately, and he can't escape. The horror of the Southern Demon Emperor can be seen.

In that medicine garden, there are many prohibitions and enchantments, but they are all very broken.

Those forbidden enchantments are dangerous for both the lower and middle supreme demons. However, for a strong man like Yang Fan, who is at the peak of the middle rank and is holding the mid-grade supreme artifact [Almighty Compass], he is vulnerable.

"No!!"

After the sea whale demon passed through the medicine garden, he suddenly screamed, and his body was eroded by the dead air, and he directly turned into a corpse and fell to the ground.

"What is that? What a strong breath! Could it be that it is the corpse of a Demon Emperor!! What he has been looking for is the corpse of a Demon Emperor!!"

The city lord of Xinhai City looked ahead, and at a glance he saw a huge and boundless monster that seemed to be able to easily devour one world after another, like a snake-like terrifying monster curled up on the ground, and the incomparably rich death qi diffused from the wounds on his body, surrounding his body, forming a sea of death qi.

"Finally found! The corpse of the Demon Emperor of the Nine Extremes Abyss!"

Yang Fan looked at the corpse of the Demon Emperor that was out of sight, a burning color flashed in his eyes, and ordered, "Golden-winged Dapeng go and test it!"

"Yes, master!"

A trace of solemnity flashed in the eyes of the golden-winged roc, and a layer of incomparably powerful spatial enchantment opened up at once, and cautiously walked towards the corpse of the Demon Emperor.

Whew!

As soon as the Golden-Winged Roc stepped into the sea of dead air, the spatial barrier that surrounded his body collapsed, and the terrifying death qi passed through the spatial barrier and landed on his body, beginning to erode his body and soul.

The Golden-Winged Roc retreated in an instant, his face pale, and his soul was eroded.

Yang Fan frowned slightly, stretched out his hand, and with a move, an improved [Demon Realm Healing Technique] landed on the body of the Golden-Winged Dapeng, slowing down the erosion of those dead qi on the Golden-Winged Dapeng.

Yang Fan calmly analyzed: "The powerhouses of the median supreme demon level can't resist the erosion of that stream of dead qi! only the upper supreme demon can resist the erosion of those dead qi and approach the corpse of that demon emperor!"

Each of the Demon Emperor powerhouses is a terrifying existence that has experienced countless battles and refined countless heavenly and earthly treasures. Each of them has once dominated the Demon Realm, and they are boundlessly powerful. Ordinary powers, that is, the existence that they kill at will.

"Then after raising to the highest realm, I'll go in again!"

Yang Fan's combat power in holding the [Almighty Compass] was already comparable to that of the Supreme Demon, and the defensive enchantment he opened with the [Almighty Compass] was also comparable to the defensive enchantment opened by the Supreme Demon. However, he still chose to be more steady.

Yang Fan returned to the medicine garden, picked those sea abyss demon grasses one by one, refined them, and transformed them into supreme evolution points.

A month later.

Yang Fan sat cross-legged on that medicine garden, and a terrifying aura of the highest supreme demon level permeated from his body.

"Superior Supreme! He actually advanced to the Upper Rank Supreme so quickly? How is this possible? Could he be the rebirth of a certain Demon Emperor? Otherwise, how could he have such a terrifying cultivation speed?"

The city lord of Xinhai City stood silently to the side, dumbfounded, with a look of disbelief flashing in his eyes. He didn't know how much time and energy he had spent on advancing to the middle supreme demon.

"That's it!"

After Yang Fan opened his eyes, he took out the [Almighty Compass] and urged the supreme power, and a layer of golden light emerged from the [Almighty Compass], forming a divine gold defensive enchantment around his body.

Whew!

As soon as Yang Fan entered the sea of dead qi, the divine gold defense enchantment on his body immediately made a crisp sound and began to be slowly eroded.

Yang Fan continued to expend his strength to maintain the birth of a new Divine Gold Enchantment, and came to the corpse of the Nine Extremes Sea Abyss Demon Emperor.
