In the ancient coffin, there is an ancient tree, and its entire body is like glass, transparent and crystal clear, and wisps of divine matter are spreading out.

"The root of the immortal spirit energy is that it permeates this ancient coffin."

Yang Yu looked at the ancient tree in front of him, exactly the same as the exorcist book he had seen before.

However, the corpse of the Pu Demon Immortal King is different. Ye Guan seems to be able to cover the sky and exude a shocking demon shadow power, as if he can make people fall into a devil.

"The body of the Immortal King is actually buried in this Baiduan Mountain? How is this possible? Is the lower realm so terrifying?"

Yang Yu frowned and directly took out an ancient coffin buried with the Immortal King. Yang Yu's breathing became heavier and he couldn't believe it.

"However, it seems normal. There are many immortals buried in the lower realm..."

After a long time, Yang Yu finally came back to his senses, his mind fell down, and he looked at the ancient coffin in front of him, and his eyes gradually calmed down.

Kunpeng Nest, the ancient cave with real dragon eggs, and the countless true immortals buried under Xiling Beast Mountain, all prove that the lower world is far from as unbearable as it looks.

Even, it is no different from the nine heavens and ten earths in the upper realm.

"However, the Immortal King's corpse is a divine object to me, but it seems that I can't use this corpse now."

However, looking at the Immortal King's corpse, Yang Yu was a little helpless. The corpse was too terrifying and its hardness could not be erased even in the years. It was even more impossible for Yang Yu to have a cave realm.

"How to use it now, this Immortal King's corpse is definitely unrealistic, but it cannot be abandoned like this."

Yang Yu put away the ancient coffin, his eyes flashing, thinking about how to deal with the corpse of the Demon Immortal King Pu.

"Refining medicine can maximize the benefits, but there is a kind of divine fire, otherwise even the corpse of the Pu Demon Immortal King will not be able to solve it."

Yang Yu has a plan. The remains of the Demon Immortal King Pu is not even worse than the immortal medicine. He has absolutely terrifying divine power.

"There seems to be a divine fire in these hundred and Duanshan Mountains."

Yang Yu's eyes flashed, Bai Duanshan was extraordinary, and perhaps a kind of divine fire could be found, which could also refine the remains of Pu Demon Immortal King.

After all, the Pu Demon Immortal King is just a corpse now, and there is no means, so it is not impossible to temper it.

"We must first go to Xiaobudian to borrow the tripod transformed into the original True Explanation and Transcendence."

Yang Yu's eyes flashed, and he went to the divine cave again, looking for the little one.

However, the trip to the Divine Cave has ended, and Xiao Budian is already eating braised lion heads.

"Oh, so many ancient relics."

Yang Yu fell from the sky, holding a feather fan in his hand, graceful and graceful.

"Damn, why is this devil here??"

"Run, Demon Yang Yu is here!"

All around, all the ancient relics onlookers ran away, and they were frightened when they saw Yang Yu.

"Baby, you eat first. If I have something to do at home, I will leave first."

The ancient relic of the ancient seed who had just had a good relationship with Xiao Budian changed his face, and he threw a piece of treasure meat and soared into the sky.

"Naked kid, I remember this battle today, and I will kill you next time!"

The nine-headed lion looked ugly, but he didn't dare to challenge Xiaobudian anymore, so he could only escape far away.

"Um?"

Yang Yu stared at the nine-headed lion.

“…”

The nine-headed lion made a cold war and didn't dare to say a word, so he quickly fled.

"Why are you here again? What should we do? Scare away all the ancient seeds, how can I fill my stomach in the future?"

Xiao Budian looked at Yang Yu with a dark face.

"Stop talking, lend me the ancient tripod from Shicun to use, and return it to you after Baiduanshan is over."

Yang Yu waved his hand, and he really couldn't stay with Xiaobudian, destroying Xiaobudian's "life and death tempering" in Baiduan Mountains.

"What do you want the ancient tripod?"

Xiao Budian took out the ancient cauldron and gave it to Yang Yu without thinking, and asked curiously.

"I'll talk about big things later. There are outsiders here."

Yang Yu waved his hand, held the ancient tripod in his hand, and left directly.

However, Yang Yu searched around in Baiduan Mountain and spent most of his time, but he could not find the real creatures of the ancient sacred mountain.

"Do you know where there is a place where the divine fire soars into the sky in Baiduan Mountain?"

A few days later, Yang Yu met Yun Xi and had to ask for information.

"There is, but that place is very dangerous."

Yun Xi spoke and frowned at Yang Yu.

"Just say anything, just say it."

Yang Yu shook his head and his eyes lit up.

"Flame Mountain, the flames in that place are very terrifying. Even the divine treasures fall into it and will become ashes in an instant, which is extremely terrifying."

Yun Xi spoke.

"It's OK, are there flames there continuous?"

Yang Yu lowered his head and pondered for a while, and asked.

If the flames in Flame Mountain are not strong enough, but can be supplied continuously, Yang Yu also has other ways to refine the remains of Pu Mo Xianwang.

"It seems that this Baiduan Mountain has existed for countless years, and the flame has never been extinguished."

Yun Xi nodded, but looking at Yang Yu's expression, she frowned and asked, "What are you going to do?"

"Refining an alchemy requires a terrifying flame to refine a medicinal material."

Yang Yu waved his hand, said nothing more, and rushed directly into the distance.

Yun Xi looked at it with a hint of worry in her eyes, but Yang Yu's back gradually disappeared and she could no longer catch up.

Yang Yu was on the road fast enough and couldn't wait. When he arrived at Flame Mountain, he finally showed a look of joy.

The divine fire in Flame Mountain is of high level, but it still cannot reach the level of burning the remains of the Immortal King.

However, Flame Mountain is the source of a innate divine fire, which can continuously produce this divine fire.

"start!"

Yang Yu took out the ancient coffin of the Immortal King Pu, the ancient cauldron of Shicun, and the Shantung halberd.

"The divine fire in Fire Mountain cannot refine the remains. Is the chief fire of the Heavenly Dao in the Silent Heaven halberd?"

Yang Yu smiled, the Silent Sphur floated up, and wisps of divine light emerged, sweeping towards the Flaming Mountain.

"swallow!"

Yang Yu shouted softly and activated the fire beads in the Shantung halberd to swallow the divine fire of the Flaming Mountain.

"Fire the Heavenly Dao Fire, come out!"

At the other end of the Flame Mountain, Yang Yu sat cross-legged under the Jitian Salute, and the remains of Pu Demon Immortal King had been put into the ancient cauldron.

With Yang Yu's low shout, strands of purple divine fire fell from the Nine Heavenly Fire Beads of the Silent Heavenly Spikes. It was the Burning Heavenly Dao Fire that Yang Yu could melt even the chaotic essence gold in the prehistoric world.

"start!"

Yang Yu is very skilled in elixir refining, even the elixir at the level of the Immortal King's corpse is extremely simple.

Yang Yu sacrificed and refined the immortal Ganoderma lucidum and other spiritual medicines he had looted from the Little West Heaven spiritual medicine field into the ancient cauldron.

For forty-nine days, Yang Yu refined the alchemy and tempered the alchemy, and finally released the cauldron, it took him 7749 days.

Yang Yu succeeded, with the Burning Heaven Dao Fire, it was not difficult to refine the remains of the Immortal King.
