"Master Wang, this is our clan's secret altar, that is, the place where the heart fire crystal is born. The patriarch has an order, you can cultivate freely here, but you can't take away the heart fire crystal here without permission. ”

Following the Elder Honghao, Wang Sanniu came to a remote cave. However, at the entrance of this cave, there are four Red Feather Phoenixes of the Jade Clear Realm guarding it, which is enough to show the importance of this place to the Red Feather Phoenix clan.

Elder Honghao held the token given to him by Hongxuan, and the four Hongling Phoenixes didn't ask much, and let them go directly. So, Wang Sanniu entered the cave alone.

Stepping through the dim hole, Wang Sanniu's eyes suddenly lit up, and an altar made of hard black diamonds appeared in his field of vision. Around the altar, there was a strong condensation of fire attribute spiritual power, and above the altar, there was a transparent red flame burning directly.

"Is this where the Heartfire Crystal was born?"

Looking at the altar in front of him, which was completely made of black diamonds, Wang Sanniu couldn't help but smack his lips. Black diamonds are one of the hardest gemstones known, and unlike ordinary diamonds, they have fire and cold resistance that ordinary gemstones cannot match.

Therefore, the price of a black diamond is also relatively expensive, a black diamond the size of a quail egg is comparable to the price of a sixth-level elixir. The altar is completely made of black diamonds, which Wang Sanniu can't even imagine.

Although the black diamond is expensive, it has no spirituality after all, and compared to the heart fire crystal in the altar, it is just ordinary.

Stepping up the steps to the altar, what Wang Sanniu saw was a bottomless cave. The crimson rock walls all exuded a rich flame attribute, and just one breath made the spiritual power in Wang Sanniu's body tremble—here, it was really a paradise for flame attribute cultivators!

Using spiritual power to maintain his figure, Wang Sanniu began his initial infiltration. The further down it goes, the more open the cave becomes, and the richness of the flame attribute is getting higher and higher. Now he feels like he's in the middle of an active volcano. The rich flame element burned his whole body.

Wang Sanniu was sure that even if he didn't have that heart fire crystal, as long as he was allowed to cultivate here for three months, he would definitely be able to break through to the Sanqing Realm. However, there is not so much time for him now, so he must find the Soul Fire Crystal, refine and improve himself quickly.

As Wang Sanniu deepened, this space had completely turned into a red color, and the light from the outside world had long since disappeared, only the red light emitted by the flame attribute vaguely illuminated this area.

"Is this the heart of the fire? ……”

After diving for five minutes, Wang Sanniu finally felt the source of a flame attribute. A pale red spar the size of a palm was quietly sticking to the rock wall, constantly exuding a rich flame spiritual power. It seems that this is the heart fire crystal that Wang Sanniu has been looking for.

Gently pasting his fingers, Wang Sanniu didn't feel very hot, but the flame spiritual power in his body was ignited all of a sudden, and the pure flame attribute gradually merged into Wang Sanniu's limbs and bones along his fingers, palms, and arms, making Wang Sanniu feel comfortable for a while, and even couldn't help but moan.

Before Wang Sanniu could finish enjoying this comfortable feeling, a heart-wrenching pain made him fall into the abyss in an instant. The flame spiritual power was quiet in all parts of his body, but when it flowed to his heart, it brought him the pain like a river and a sea.

"No wonder it's called 'Heart Fire', is it actually this effect......

Forcibly enduring the colic in his heart, Wang Sanniu worked hard to operate his spiritual power and began to take this opportunity to cultivate. Although the pain at this time is indeed far beyond what people can bear, it does make the spiritual power in Wang Sanniu's body continue to increase, and it also makes his flame continue to sublimate.

Wang Sanniu, who has experienced the quenching of the Dragon Immortal Dew, the meridians in his body are considered to be relatively powerful existences of the same level, so even if the fragile place like the heart has been tempered by the heart fire, it is still within the range that Wang Sanniu can endure.

If he were to be an ordinary Divine Desperate Realm cultivator who came here, I am afraid that it would not be long before he would have to stop and relieve the cramping pain in his heart, but Wang Sanniu was able to rely on his own advantages and continue to endure it. In this way, his cultivation effect can also be optimal.

After a stick of incense, Wang Sanniu gradually found that his heart didn't seem to hurt as much as before. When he opened his eyes, he saw that the fire crystal in front of him had become dim, as if it had turned into an ordinary gem, and no longer had spirituality.

"Have you run out of power? ……”

Wang Sanniu withdrew his hand and clenched his fists, a little unsatisfied. He could feel that just for the time of this incense, it was as if he had been cultivating for several days, and his spiritual power had already made visible progress with the naked eye. Moreover, the flame attribute in his body was also constantly sublimated in the tempering just now, and it seemed to have become more pure.

"Wang Sanniu, would you mind if I regained my strength here?"

Without waiting for Wang Sanniu to look for the next piece of heart fire crystal, Bi Fangniao actually appeared from Wang Sanniu's body and came to Wang Sanniu in the form of a woman.

"You are free...... Wang Sanniu was a little puzzled, why Bi Fangniao asked like this.

"You can think clearly, if I regain my strength here, it is very likely that I will complete the materialization, and you will not be able to suppress me at that time, aren't you afraid that I will take it?" Bi Fang Bird is colorful.

"I still say that no bad guy is stupid enough to tell his victims about his evil plans. Moreover, if you really have the heart to give up, there are not many opportunities before, and there is no need to wait until this time.

The main thing is that I have seen you clearly in the past few years of getting along. You're not as scary as rumored, you're just hot on the outside, and I'm still quite cute. So...... I believe you. ”

Wang Sanniu looked at Bi Fangniao with a warm smile on his face.

"Hmph, you'd better pay attention to it, don't be so big and small. For thousands of years, no one has ever used 'cute' to describe this seat......" Bi Fangniao snorted coldly, and directly turned into its original form and flapped its wings away.

"And ...... Knife mouth tofu heart ......"

Looking at her departing back, Wang Sanniu shook his head with a smile and continued to dive, looking for the next piece of heart fire crystal. Now he had understood that the moment his flame was completely purified by his heart fire was the moment when his cultivation here ended. Whether or not you can break through the Three Qings depends on how much you can cultivate during this time......
