For this cave, Tang Huan has long been quite curious.

He originally wanted to wait for the "Fengling Martial Arts Meeting" to end, and then come in and take a look when he was fully prepared, after all, he had been in here for a long time, and he was already hungry, if he continued to go deeper, if something happened and he was trapped, if he delayed the martial arts meeting, he might be starved to death.

But with a little guidance, the situation is very different, and what can make it so interesting must be a gemstone, and it is probably not far away.

In that case, it doesn't hurt to go in and have a look now.

In the blink of an eye, Tang Huan was already striding towards the depths of the cave, and with a cheerful "babbling", he jumped on Tang Huan's shoulder with four paws.

The blood-red stone cave meandered, and the further forward it went, the more intense the heat wave became.

After advancing for about two hundred meters, Tang Huan was already sweating profusely, and the heat of this place was a little unbearable even for him. But just when Tang Huan was about to run the "Heaven and Earth Jiaotai Jue" and urge the power of true fire to resist the invasion of heat, in the dantian, the "Jiuyang Divine Furnace" suddenly took the initiative to rotate.

"It's ......"

A trace of doubt flashed in Tang Huan's eyes.

Such a change also occurred in the "Jiuyang Divine Furnace", that is, when the "Pure Yang Danzhu" in Shanshan's body occurred. Now that the Ding Furnace is showing such movement again, it could be that there is something similar to the "Pure Yang Danzhu" in front of the cave.

Thinking about it, Tang Huan sensed it carefully.

Just a moment later, Tang Huan discovered that with the rapid rotation of the "Jiuyang Divine Furnace", there was actually a trace of subtle and strange pure heat separated from the surrounding heat waves, quickly penetrated into the body, and followed the meridians into the Dantian Ding Furnace.

Without the wisps of strange heat, the heat around it dropped suddenly.

"Nirvana Flame?"

In the next moment, Tang Huan's mind fluctuated.

The aura that was exuded by the heat absorbed by the Ding Furnace was extremely similar to the phoenix feather that Gu Fei gave him in his arms.

Although the strength of the heat emitted by the two is different, it is the same, and it seems to have the same root and origin.

"Could it be that the 'Nirvana Holy Fire' is in the depths of this cave, not the Fengling Valley over there?" Tang Huan couldn't help but have such a thought flashing through his mind.

If the "Nirvana Holy Flame" really appeared in front, Tang Huan would not be surprised at all. The "Nirvana Holy Fire" was not a dead thing, it was one of the five great spiritual fires, it had existed for countless years, and its spirituality was extremely strong, so it was not surprising that it had been transferred from the Phoenix Spirit Valley to the Blood Flame Peak.

"To go, or not to go?"

The blood-red cave didn't know how far it would go forward, but Tang Huan was a little hesitant.

The "Nirvana Holy Flame" was one of his goals when he came to Fengming Mountain, and he never thought that he would encounter the "Nirvana Holy Fire" so soon.

In his original idea, he would wait for the "Phoenix Spirit Martial Meeting" to end before acting. At that time, without the attraction of "Feng Yan Marrow", the many martial artists gathered would definitely disperse quickly, and he could also slowly search for traces of spiritual fire without worrying about being disturbed too much.

But the plan can't keep up with the changes at all.

He had just come to this Blood Flame Peak to look for Feng Yu, but by mistake, it was actually possible to find the true hiding place of the "Nirvana Holy Fire".

"Now that you're here, how can you back down?"

In an instant, Tang Huan made a decision and continued to march.

However, when he took a step forward, Tang Huan had already run the exercises to the extreme, and within the dantian, the "Jiuyang Divine Furnace" and the Spirit Wheel were all spinning rapidly, and that strange heat penetrated into the body at a faster speed, and then was refined and absorbed by Tang Huan little by little.

The heat wave was like a raging wave, constantly whistling, but as soon as he got close to Tang Huan, the strange heat contained in the heat wave was absorbed into it, and the heat that Tang Huan could sense suddenly plummeted, and it was almost the same as the entrance of the cave, which was completely within Tang Huan's tolerance range.

"Little bit, what you just discovered wasn't a gem, but a 'Nirvana Holy Flame', right?" Tang Huan walked vigorously and couldn't help but smile and ask.

"Hubble?"

Xiao Budian scratched his head, and seemed to be a little confused.

Tang Huan smiled dumbly, such a possibility is not impossible, whether it is the "Phoenix Stone" or the Phoenix Feather, the thermal aura contained in it is actually very similar to the "Nirvana Holy Fire". The heat of the surging heat contained the hot breath of the Holy Flame, and it was normal for it to be misjudged.

After continuing to travel for nearly a kilometer, the strange heat was more than ten times stronger.

Tang Huan's speed of refining heat has completely failed to keep up with the speed of heat absorption in the "Jiuyang Divine Furnace", and more and more heat has begun to gather in the Ding Furnace.

At this moment, the cave in front of him suddenly expanded sharply, and two blood-red gates suddenly entered Tang Huan's line of sight.

The two doors are several meters wide and more than ten meters high, and there are almost no gaps between them.

On the surface of the gate, each carved an upside-down fiery red phoenix, with long tail feathers connected, and the phoenix's beak opposite, connected into a large circle. The heat that filled the cavern passage emanated from the door, wave after wave, as if it would never stop.

"Since there is a door, there must be a hole behind the door!"

Tang walked happily to the door, if the "Nirvana Holy Fire" was really in the depths of this cave, then it must be behind these two gates.

It's just that I don't know how to open these two doors? Tang Huan's thoughts turned sharply, and his palms full of true qi fell on the door, and with a push of luck, the two doors did not move at all.

Seeing this, Tang Huan immediately understood.

If you want to push this door open, you should not be able to use your dead strength, and besides, this door must also be able to be opened, otherwise, how did the person who made this door get in? How could the "Nirvana Holy Fire" get in? In the blink of an eye, Tang Huan began to observe carefully.

"Huh?"

After a while, Tang Huan found that under the heads of the two phoenixes, there was actually a fiery red ring that rose above the door, which was crystal clear, as if it was carved from beautiful jade. Each ring is as thick as three fingers and the size of two basketballs.

Tang Huan only hesitated slightly, then stretched out his hands and held a ring in each.

But the next moment, Tang Huan frowned slightly.

Almost as soon as he touched the ring, he felt a strong absorbing force, which actually firmly adsorbed his two palms on the ring, and then, the true qi in Tang Huan's body was triggered, surging out like a flood of a broken embankment, and disappeared into the ring.

"This thing can suck power. ”

Tang Huan's brows furrowed more and more, with the speed at which this ring was absorbing true qi, I am afraid that it would not be long before the true qi in his body would be consumed.

Between his thoughts, Tang Huan urged the real fire.

Under the coercion of the power of true fire, the strange heat gathered in the dantian passed through the spiritual veins, revealing both palms, and was also absorbed by the ring.
