Yang Fan stretched out his hand and pressed it on the corpse of the Demon Emperor.

Dead qi instantly eroded Yang Fan's right hand, and a trace of gray aura began to emerge. Even if it is a terrifying existence of the upper rank and the highest number, it is difficult to resist in the face of the erosion of the Demon Emperor's dead qi, and if you are not careful, you will be eroded and become all kinds of monsters.

If you want to resist the erosion of the death qi of the Demon Emperor powerhouse, you must at least have the strength of the Supreme Demon King level.

"Do you consume 10,000 Supreme Evolution Points to condense the Demon Emperor's power crystal?"

"Yes!"

Countless supreme evolution points poured into the Demon Emperor's corpse along Yang Fan's right hand.

The corpse of the Demon Emperor instantly appeared with countless mysterious spell marks, and the huge and incomparably powerful power frantically converged and submerged into Yang Fan's palm.

A power crystal engraved with countless mysterious spell marks condensed in Yang Fan's right hand.

The corpse of the Demon Emperor also began to slowly crumble, turning into ashes and drifting away in the wind.

A year later, the corpse of the Nine Extremes Sea Abyss Demon Emperor completely collapsed and turned into ashes.

Yang Fan looked at the power crystal in his hand, and a trace of burning color appeared in his eyes: "Finally extracted the power of the Demon Emperor!!! The Demon Emperor is really terrifying, worthy of being a powerhouse in the only realm of half a step!"

After inheriting the inheritance of Wanyuan Divine Monarch, Yang Fan also knew a lot of common sense in cultivation.

After the supreme realm, there is the higher realm that the god emperor and the demon emperor in the two worlds of gods and demons are pursuing, and that is the only realm. Theoretically, once you advance to the One Realm, you can survive the destruction of the universe.

The God Emperor and the Demon Emperor are all terrifying existences in the half-step realm. Theoretically, they are only the powerhouses of the Great Secret Realm of the Supreme Realm, but they have already set foot in some of the mysteries of the One Realm, and they are incredibly strong.

"Let's get started!"

Yang Fan stuffed the Demon Emperor Crystal directly into his mouth, swallowed it in one gulp, and then urged the Supreme Evolution Points to begin refining the Demon Emperor Crystal.

Countless black magic lights poured out from that Demon Emperor Crystal and submerged into the [Evolution] Crystal in Yang Fan's Brain Domain Skill Ring.

A trace of terrifying aura slowly diffused out from Yang Fan's body, spreading in all directions.

Time passed, and three years passed in a flash.

"[Evolution] quality is the only one in half a step!"

A line of information suddenly appeared, Yang Fan slowly opened his eyes, and a terrifying aura of the Supreme Demon King level permeated from his body.

A trace of regret flashed in Yang Fan's eyes: "I have finally advanced to the Supreme Demon King!, unfortunately, the resources here are not enough for me to advance to the only one half step and become the Demon Emperor!"

After the [Evolution] skill quality has advanced to become the only half-step, this means that Yang Fan has opened the only way to the half-step advancement. As long as the resources are sufficient, it is possible for him to break through the barriers and advance to become a powerhouse in the half-step realm.

It's just that in this secret realm, except for the corpse of the Nine Extremes Sea Abyss Demon Emperor, the other resources are not enough for Yang Fan to advance to the Demon Emperor.

"Black Mist Demon Tide, it's still too dangerous there! And with my strength, it's basically impossible for the Sky Snatcher Demon Emperor to let me in. ”

Yang Fan suddenly thought of the Black Mist Demon Tide where the Sky Snatching Demon Emperor was, but he had no choice but to give up the next moment.

"Let me see what else is good in this secret realm!"

Yang Fan began to walk in that broken secret realm, looking for resources that would be useful to him.

In that ruined secret realm, there were still powerful enchantments in many places, and even the powerhouses of the upper rank and the highest rank did not dare to act rashly.

However, Yang Fan had already advanced to the realm of the Supreme Demon King, and he broke through those enchantments casually, plundering all kinds of resources in that secret realm to his heart's content.

A sword light flashed, and a pitch-black gate instantly split apart, turning into countless fragments scattered on the ground.

"Found it!"

As soon as Yang Fan entered the door, his eyes suddenly lit up: "There are so many treasures!"

In that treasure house, there are all kinds of heavenly and earthly treasures of great power levels.

Yang Fan raised his eyebrows slightly: "These are top-notch heavenly and earthly treasures, which can create a super-grade supreme artifact." But there are no materials to make the Emperor's Weapon!"

The so-called Emperor Weapon is a terrifying secret treasure of the half-step unique level that the God Emperor and the Demon Emperor have spent countless years and months to create.

A matching emperor weapon can increase the combat power of a god emperor and a demon emperor by about 20%!

In the Demon Realm, in addition to the Four Emperors of the Demon Realm, there are also other Demon Emperors. It's just that most of those Demon Emperors are defeated under the Four Emperors of the Demon Realm. One of the biggest gaps between them and the Four Emperors of the Demon Realm was that none of them had their own imperial weapons.

"However, with these materials, I can just raise the [Almighty Compass] to the point of being a super-grade supreme artifact. In this way, even if it is a Demon Emperor powerhouse, it will be difficult to find my position through the Heavenly Machine Technique. And my ability to predict the blessings and misfortunes of heaven will be even better!"

"Before that, I can merge this world into the [Yanhuang Cave Mansion] and improve the quality of the [Yanhuang Cave Mansion] again!"

Yang Fan strode to the control center of that secret realm, and poured supreme evolution points into it, eroding the control center of that secret realm.

After controlling the entire secret realm, Yang Fan moved his mind and included that secret realm in the [Yanhuang Cave Mansion].

As soon as that secret realm was included in the [Yanhuang Cave Mansion], the world tree in the entire [Yanhuang Cave Mansion] immediately bloomed and began to absorb the entire secret realm for transformation.

Yang Fan's mind moved, and the massive number of supreme evolution points were submerged into the [Yanhuang Cave Mansion], so that the [Yanhuang Cave Mansion] began to evolve.

"Top-grade supreme artifact [Yanhuang Cave Mansion]. ”

Yang Fan's eyes showed a hint of satisfaction: "Yes! At present, there are five hundred medicine gardens that can cultivate supreme divine medicine! If it is in the Cangxing Realm, it can be cultivated in a hundred years. If it is in a place where the demonic qi of the Demon Realm is strong, it only takes ten years to harvest a batch of supreme divine medicine!"

In the Demon Realm, the reason why those powerful forces have fixed nests is because those huge forces can only cultivate supreme elixirs and other heavenly and earthly treasures in those places where the demonic energy of the Demon Realm is strong.

There is also such a reason why the Four Emperors of the Demon Realm dominate the Demon Realm and occupy the territory of the Four Demon Realms respectively. After the Four Emperors of the Demon Realm dominate the Demon Realm, there will be countless powerhouses working for them, collecting all kinds of heaven and earth treasures.

Similarly, the location of the lair of the Four Emperors of the Demon Realm is also the place where the demonic energy of the Demon Realm is the strongest, and all kinds of magical potions can be cultivated.

"First of all, we must strengthen the [Sun God Furnace] and let it also advance to the Supreme Artifact, otherwise it will not be able to refine the main materials of those super-grade Supreme Artifacts at all. “

Yang Fan threw all kinds of heavenly and earthly treasures into the [Sun God Furnace] and began to forge and strengthen the [Sun God Furnace].
