In the vast invisible flame, Huo Xuan shook his head vigorously, forcing himself to remain calm and clear.

At this time, Huo Xuan's body was shrouded in a layer of cyan blue flames, and on the periphery of that flame, there was a large mass of invisible flames circling back and forth like a small snake, and the terrifying temperature even though it was isolated by blue and blue fire, it still made Huo Xuan's skin feel the same way.

"Tsk!"

Suddenly, a burst of furious sound waves full of excitement came out from the invisible flames, and the sound waves that were sharp enough to make an ordinary fighting spirit detonate his body on the spot spread rapidly, and then hit the magma under the deep cave, and suddenly, the magma world seemed to be thrown into countless bombs, and the low roar continued to sound, and the huge blood-red magma suddenly surged up from the ground, and finally carried the momentum of overwhelming the mountains and seas, covering the entire deep cave all over the world.

With a sweep of his eyes, whether it was up and down or left and right, everywhere he entered, there were countless crimson magma flowing slowly like blood, Huo Xuan knew that here, the power of the Falling Heart Flame was almost endless, although Huo Xuan could break through its blockade and leave, but for the plan to subdue the Falling Heart Flame, Huo Xuan showed weakness and let the Falling Heart Flame surround him, while the Falling Heart Flame tried to refine Huo Xuan, Huo Xuan was also taking the opportunity to find its origin.

After all, attacking the Falling Heart Flame indiscriminately is just a waste of power, and what Huo Xuan sees now is just the appearance of the Fallen Heart Flame, the real Falling Heart Flame Origin, hiding somewhere in this huge form body, as long as Huo Xuan finds it out and causes damage to that source, then the Falling Heart Flame will naturally be hit hard.

Huo Xuan raised his head slightly, his eyes scanning this huge invisible flame, it was hard to imagine that this flame actually had its own spiritual intelligence...

In Huo Xuan's glance, somewhere in the invisible flame, two faint green rays suddenly appeared, like a pair of eye pupils, looking at Huo Xuan's location with greed, the green light flashed slightly, and after a while, Huo Xuan seemed to understand something, and suddenly secretly said something bad in his heart, and at the moment when his voice just fell, he clearly sensed that an extremely hot heart fire suddenly appeared in his body.

At the heart of Huo Xuan's body, there was a fiery heart fire that appeared strangely, and then unscrupulously released a high temperature full of destructive power, and the momentum was as if everything in Huo Xuan's body was going to be burned to the ground.

The moment the fire in the heart of the body appeared, Huo Xuan's face also changed slightly, he was now extremely jealous of this heart fire, his mind moved, the blue flame in Huo Xuan's body surged rapidly, at an extremely fast speed, before the heart fire completely released the high temperature, it was firmly wrapped, and then slowly and forcibly incinerated it into nothingness...

Feeling that Huo Xuan was able to resist its heart fire, two faint green rays of Falling Heart Flame appeared, and a strange scream full of anger resounded in Huo Xuan's ears, and then, two points of faint green light suddenly rose, and a cluster of extremely hot and fierce invisible flames suddenly poured out from the four walls of the Falling Heart Flame, and then surrounded Huo Xuan in all directions, and finally adhered to the blue flame on Huo Xuan's body, burning and eroding it.

Moreover, when the outside began to attack on a large scale, Falling Heart Flame also summoned a fierce heart fire in Huo Xuan's heart again, and then frantically wantonly destruction, looking at his actions, it was obvious that he wanted to completely kill Huo Xuan's stubborn guy under this internal and external attack.

Exhaling deeply, the blue flames in Huo Xuan's body surged along the meridians, and finally slowly penetrated out, constantly resisting the erosion of the heart fire in the body and the invisible flame outside the body.

Although the consumption of Dou Qi is a bit huge, there is a big gap between the Falling Heart Flame and the cyan blue flame formed by the fusion of the three different fires of Qinglian Earth Heart Fire, Wind Thunder Fury, and Sea Heart Flame, so for such a consumption, Huo Xuan can support it for a while.

"Calm down, look for the origin...", muttering almost to himself, Huo Xuan slowly exhaled again, with the help of the medicinal power of the Qingxin Pill, Huo Xuan's originally restless heart also quietly became calm.

As his mind became calm, Huo Xuan's dark eyes were slowly flooded with a strange blue flame, and as the blue flame filled Huo Xuan's eyes, the world that appeared in front of him suddenly changed greatly.

Although it is still a red world, but the surrounding Falling Heart Flame is slowly becoming transparent, and in that transparency, a palm-sized, somewhat milky white flame snake is constantly flashing, the pupils of the little snake are full of invisible flames, and the eyes are turning, it looks quite agile, it is obvious that this little snake has spiritual intelligence.

And when Huo Xuan looked at the flame snake, the latter seemed to have discovered him, and at that moment, the pair of snake pupils were filled with fierceness, and terrifying invisible flames slowly rose from their bodies.

"Is this the true origin of the Fallen Heart Flame..."

His eyes blinked slowly, and Huo Xuan chuckled, although the large flames around him seemed to be all Falling Heart Flames, but if you want to crack it, you must find the most core part, and this little flame snake is where this core is!

Slowly stretching out his left hand, Huo Xuan smiled at the place where the little flame snake was hiding.

Seeing Huoxuan's smile, the little flame snake that couldn't be seen with the naked eye seemed to notice that something was wrong, and with a flick of his tail, his small body was like lightning, shuttling around, trying to avoid Huoxuan's sight.

"Want to run?"

In the eyes full of flames, the flame snake's every move was extremely clear, the corners of Huo Xuan's mouth were raised, his left hand was slammed, and in the palm of his hand, a trace of silver space power flashed out, and suddenly, the surrounding free space energy entered an instant solidification at this moment.

The spatial solidification only lasted for a moment, and it was burned and distorted into nothingness by the raging invisible flames, but above Huo Xuan's right hand, the blazing flame sword swung violently at the moment when the flame snake was stagnant.

Suddenly, the increasingly dense flame sword slashed through the void like lightning, extreme speed, terrifying power, and violent flames, causing the entire space to fluctuate violently at this moment......
