"However, among all the treasures of the Young Master of the Black Bone Demon Sect, the most precious thing is this lamp!"

Yang Fan's heart moved, and a broken bronze lamp suddenly appeared in his hand. As soon as he grasped the bronze lamp, he sensed a trace of power fluctuations of great energy levels coming from it.

That bronze lamp was the treasure that Yang Fan sensed with the help of the remnant power of the young master of the Black Bone Demon Sect with the help of the Heavenly Technique.

"Except for a hint of power, this bronze lamp is unremarkable and has no special powers. But!"

Yang Fan's figure flickered, and suddenly appeared above the Demon Realm Kunpeng Giant Boat.

Circles of mysterious cyan light appeared on the bronze lamp, turning into a bronze indicator sign pointing towards the depths of the black fog demon tide.

Yang Fan's eyes lit up: "The young master of the Black Bone Demon Sect has amazing wealth and a powerful father. This treasure turned out to be his most precious treasure, so there was only a place where treasures such as the Great Power Cave, the Treasure, or the Supreme Artifact existed!"

"But before that, I still have to refine the essence of those demon lords, and then restore the Yanhuang Cave Mansion into a supreme artifact!"

"Dark Poison Red Leaves, I'll leave it to you here!, move in the direction of this bronze lamp!"

With a wave of his hand, Yang Fan threw the bronze lamp into the hand of the dark poisonous red leaf.

"Yes, master!"

A hint of excitement flashed in the beautiful eyes of the dark poisonous red leaves, and then she showed a provocative smile to the Yin Qingwu sisters who were standing quietly beside Yang Fan.

The tone is dull and the face is expressionless.

Yin Qingwu smiled slightly, and followed Yang Fan with Yin Wuguang in her arms.

Yang Fan's mind moved, and he returned directly to the Yanhuang Cave Mansion and began to retreat and cultivate, refining the main elixir and the essence of the demon lord.

"+3.5 Evolution Point Supreme!"

"The quality of these demon lord's essences is too poor, and most of them are the essence of the lower demon lords. There is no essence of the superior demon lord and the king of the demon lord. However, it's enough to allow the Yanhuang Cave Mansion to fully recover!"

Yang Fan's mind moved, and 1 supreme evolution point was submerged into the Yanhuang Cave Mansion.

In the center of the Yanhuang Cave Mansion, countless mysterious and unpredictable lights shone, and the entire Yanhuang Cave Mansion was full of light, and countless starlight and vitality converged in the center of the Cave Mansion.

A sapling of the World Tree began to grow rapidly in the center of the cave, reaching into the sky, blooming with incomparably brilliant divine light.

When the sapling of the World Tree grew to 100,000 miles, it suddenly bloomed with incomparably brilliant divine light, and endless vitality suddenly diffused in the Yanhuang Cave Mansion, and the Yanhuang Cave Mansion seemed to have become a world at once.

"Inferior Supreme Artifact Yanhuang Cave Mansion!"

Yang Fan's eyes showed a hint of satisfaction: "Not bad!

As soon as the Yanhuang Cave Mansion advanced to the low-grade supreme artifact, it evolved into a world that could continuously draw power from the world sea and continue to grow, forming a great world in its own circle.

If Yang Fan left directly, he would leave the Yanhuang Cave Mansion. Even if 10 billion years pass, the Yanhuang Cave Mansion will not be destroyed, but will continue to exist like the Cangxing Realm, and it is possible that it will continue to grow and evolve, and the power of evolution will never be exhausted.

In addition, once Yang Fan hid in the Yanhuang Cave Mansion, he could mobilize the power of the Yanhuang Cave Mansion to open a layer of extremely powerful defensive barriers, even if the powerful powerhouses of the Supreme Realm attacked, it would be difficult to break through the defenses of the Yanhuang Cave Mansion.

Of course, the Yanhuang Cave Mansion can only barely resist the attacks of those weakest powers now, if the top powers, or the Demon Emperor's powerhouse, can still break through the entire Yanhuang Cave Mansion.

"If my Yanhuang Cave Mansion fuses with a strong man of the Demon Lord King, he can exert a weak and powerful combat power in this Cave Mansion! However, that doesn't make much sense!"

Yang Fan thought for a while, and then gave up this idea.

After all, a weak power that can only stay in the Yanhuang Cave Mansion is of little use to Yang Fan now, but it consumes a lot of resources.

In addition, as soon as the Yanhuang Cave Mansion advanced to the supreme artifact, the time for cultivating the true divine medicine, the main divine medicine, and the demon main medicine was shortened by a large margin.

In fact, the Yanhuang Cave Mansion is not a supreme artifact of the combat class, but a supreme artifact that tends to be of the logistics class. As long as there are some seeds of the Supreme Divine Medicine, then the Yanhuang Cave Mansion can continuously cultivate the Supreme Divine Medicine.

"Now there are two more gardens where the Supreme Elixir can be cultivated, and there are five! If there is a seed of the Supreme Elixir, one garden can cultivate one Supreme Elixir. About every thousand years, I will be able to harvest 5 supreme elixirs!"

"In just a hundred years, I can get a thousand main elixirs. “

"This speed is extremely unnatural for other powers!, but for me, it's still too slow!!"

"If you want to continue the life of the green bead, the main elixir is enough. However, if she wants to take her foundation recovery to the next level, she needs the supreme elixir. “

Yang Fan analyzed quietly.

Emperor Zero forcibly killed a True God Strongman and was injured in the Origin, and it can be said that most of him has died, and the True God Medicine can only prolong his life.

However, there are also countless treasures of heaven and earth in the Demon Realm, and many Demon Masters can prolong the life of the Zero Emperor. However, the best effect on him was the supreme elixir! It was a treasure of the Demon Realm that could only be enjoyed by great powers, and the Demon Realm was not sold on the Internet at all.

No matter where it is, the supreme elixir is an incomparably scarce existence.

"So many demon main pills and the corpses of those demon lords can just increase the strength of the Golden-winged Roc!"

Yang Fan's mind moved, and he began to consume a large number of main god evolution points to improve the strength of his subordinates. He consumed more than 1,000 main god evolution points and 1 supreme evolution point to elevate the golden-winged roc to the realm of the king of the demon lords.

In addition, Xiao Hei also consumes the same resources to advance to become the king of the demon lords.

The four powerhouses of the Yin Qingwu Sisters, Lang Jiu, Qi Qi, and Dark Poison Red Leaf have also advanced to become high-level demon masters.

Ten days later.

Suddenly, a lower demon lord shrouded in dark power, with a thousand tentacles and ten eyes, poured out from the black mist demon tide.

"Meow~!I'll come~!I'll kill him!No one is allowed to shoot!"

Little Black's eyes lit up, and a hint of excitement flashed as he shouted.

After the black scorpion advanced to the king of the Demon Lord, he had never encountered an opponent in the Demon Lord Realm, and now he was naturally excited to meet a monster in the Demon Lord Realm.

The golden-winged Dapeng and other powerhouses glanced at the demon lord, and many people were eager to try, but in the end they didn't make a move. After all, Xiao Hei was the first demon beast to follow Yang Fan, and he was also one of the most favored powerhouses under Yang Fan's command!
