The Thunder Fire Ancient Cave is also a place of opportunity within the Gate of the Ancient Gods.
The strange fire and thunder in it are naturally coveted.
However, for the strange fire and thunder, the Fire Tribe and Thunder Tribe are the ones most in need.
The Fire Tribe suffered heavy losses in the Ancient Forbidden Territory, and even Yan Xuanji died. This time, no genius from the Fire Tribe came to the Gate of the Ancient Gods.
As for the Lei Clan, after Ye Guchen killed Lei Jiuyou, only Lei Jiuyou was left.
Ye Guchen is not too afraid of Lei Jiuyou, but he will not underestimate him either.
After all, he is a person who has gained the meaning of life and death. Even if he has not completely stepped into the realm of life and death, he is probably not far away.
As soon as he entered the Thunder Fire Ancient Cave, Ye Guchen felt a strong blazing aura, mixed with the explosive power of thunder, rushing towards him.
"It can temper the physical body." Ye Guchen's eyes lit up.
Strange fire and thunder are the best materials for tempering the physical body.
Besides, he has practiced the Ancient God Art, and his physical body also needs to be tempered.
Ye Guchen did not protect his body with the demon armor, but instead let go and accepted the tempering of red flames and thunder.
However, the flames and thunder outside the Thunder Fire Ancient Cave are the most ordinary ones, and their tempering effect is limited.
For Ye Guchen, who was possessed by strange fire and thunder, it did not have much effect.
He gradually went deep into the depths of the Leihuo Ancient Cave.
As we go deeper, the surrounding environment becomes more and more extreme.
If it were an ordinary saint, son or daughter, it would be impossible to move forward without using the power of totem to protect oneself.
However, Ye Guchen was calm and composed, like a fish in the water, undergoing tempering.
At this moment, Ye Guchen's steps suddenly stopped.
The fire of Tianyang Xuanming Fire in his body seemed to tremble.
It was an aura that sensed similar species and threats.
"Wonderful fire in heaven and earth!"
Ye Guchen almost didn't hesitate at all and escaped directly into the depths of the Thunder Fire Ancient Cave.
The depths of Leihuo Ancient Cave are like a honeycomb, with many caves scattered throughout.
Most of the caves contained only ordinary flames and thunder.
Only a very few caves have strange fires and thunder.
However, relying on the perception of Tianyang Xuanming Fire in his body, he also chose a cave and escaped directly into it.
The deeper you go, the more intense the intense heat becomes.
However, the strange thing is that the fiery power does not seem to only burn the physical body.
Even the soul feels like it is being burned.
The light in Ye Guchen's eyes became brighter and brighter.
Finally, at the end of the cave passage, the space suddenly widened, and within it, there was a black flame suspended in mid-air.
As the pitch-black flame rolled, there was a faint and breathtaking wave coming out, as if it were a will-o'-the-wisp.
"That's the Heart-Destroying Demon Flame!" Ye Guchen's eyes showed a hint of surprise.
He followed the old drunkard for a while, and the old drunkard almost told Ye Guchen about most of the strange fires and thunder types in the world.
If Ye Guchen saw this pitch-black flame correctly.
It is the inner demon flame of annihilation that is rumored to be able to burn the soul and even arouse inner demons.
The Nirvana Heart Demon Flame ranks very high among the strange fires of heaven and earth, far superior to the Tianyang Xuanming Fire in Ye Guchen's body.
It even almost caught up with the old drunkard's Purple Emperor Skyfire.
However, the unique and terrifying ability of the Nirvana Heart Demon Flame to burn the soul cannot even be matched by the Purple Emperor Sky Fire.
"Sure enough, I will give you a pillow when you feel sleepy." Ye Guchen couldn't help but reveal a faint smile on his lips.
He wanted to go to the Fire Tribe before to see if he could get the strange fire that burned the soul.
But there has never been a chance.
But now, there is finally a fire that can help Ye Guchen overcome the sea of consciousness and soul tribulation.
However, there is a reason why this Demon-Destroying Flame has been able to exist in the Thunder Fire Ancient Cave for a long time without being collected by anyone.
Because the Nirvana Heart Demon Flame is very difficult to refine.
Thinking about it, Ye Guchen's refining of Tianyang Xuanming Fire was extremely dangerous.
Not to mention the Heart-Destroying Demon Flame.
If the difficulty of refining Tianyang Xuanming Fire is one, then the difficulty of refining the Nirvana Heart Demon Flame is over fifty.
This is not a level of flame at all.
Coupled with the unique ability of the Soul-Destroying Heart Demon Flame to burn souls, even some Holy Sons of the Fire Tribe who came here did not dare to refine it before.
Ye Guchen's eyes suddenly swept away.
Suddenly, I discovered that there were some corpses in this space.
Judging from their appearance, they are all saints and saints who failed to refine the inner demon flame of annihilation.
These corpses have long been charred black, and each of them has a distorted shape, as if they have suffered tremendous torture.
Ye Guchen's face was also slightly solemn.
No wonder the Heart Demon Flame of Annihilation has been here for a long time and no one has been able to take it away.
Because everyone who tried to refine it and take it away was already dead.
The Demonic Flame of Annihilation is just like its name, and it also has a terrifying special ability.
It is the ability to use its own flames to arouse the inner demons in people's hearts.
This kind of inner demon may be some kind of obsession, it may be a certain person, or it may be some kind of painful memory.
All in all, inner demons are extremely terrifying.
Clues can be seen from these twisted corpses of dead people.
Even in the future, when Ye Guchen reaches a higher level in cultivation, he will also have to withstand the test of his inner demons.
"The road to martial arts is to go against the current. If you are afraid, how can you reach the supreme peak?" Ye Guchen's eyes were filled with determination.
His character no longer needs testing.
If it were anyone else, even if the leader of the Fire Tribe came here and saw the Nirvana Heart Demon Flame, he wouldn't necessarily dare to refine it.
But Ye Guchen dared.
Because he has not forgotten his blood feud and Gu Shaoyang.
If you want to defeat Gu Shaoyang, the top talent in the Southern Territory and one of the top ten young masters.
How can we do it without fighting?
The Nine Tribulations Heart Sutra is Ye Guchen's strongest means of crushing these geniuses from the Southern Heaven Region.
Therefore, Ye Guchen must survive the Soul Tribulation of the Sea of Knowledge!
The Demonic Flame of Annihilation must also be refined!
"Let's get started."
This place is quiet and deserted, which is a good time for refining.
Ye Guchen slowly approached the Heart-Destroying Demon Flame.
The Demonic Flame of Annihilation also seems to have spirituality, and it rolls more violently.
"It actually has a hint of spirituality. It deserves to be regarded as a top-notch magical fire." Ye Guchen secretly said.
At this time, in the violently rolling black flames, it gradually materialized into a terrifying human face.
The human face cannot speak, but it can make a ghostly howling sound, which is frightening and frightening, as if the soul is about to be shattered.
"When you meet me, you have no right to resist. You can only become my flame and be used by me."
The true energy and totem power in Ye Guchen's body suddenly exploded.
The power of the two attributes was sacrificed by Ye Guchen at the same time, directly wrapping the Nirvana Heart Demon Flame in it.
The pitch-black flames suddenly seemed to be boiling, and the ghostly roar became sharper and shriller, almost threatening to shatter the sea of consciousness.
But Ye Guchen's consciousness was protected by the Starfall Demonic Soul Butterfly, so he was not affected.
"Destroy the Heart Demon Flame, let me see how difficult it is to refine you!"
The power of true energy and totem directly compressed the fire of the Annihilating Heart Demon Flame into the size of a fist.
