"Bang!"

It seemed that a huge fireball exploded in the heart palace, and the scorching heat flow rolled out along the two veins of heaven and earth, and in an instant, it spread to all the meridians and hidden apertures. Immediately, the true qi in the meridians and hidden knots was like boiling boiling water, surging violently.

"Hmm!"

Mu Han snorted, feeling like a monkey stuffed into the Taishang Laojun gossip furnace, all the internal organs seemed to be bursting into flames, and even the breath that erupted seemed to be burning violently. With a flick of his fingers, Mu Han's skin became red.

At this moment, all the pores on Mu Han's body seemed to open up, and he kept spewing flames outward, and the crazy surging heat seemed to burn him to ashes.

Mu Han gritted his teeth tightly, his mouth made a rattling sound, and the ten fingers of his hands were actually trapped in the purple star stone, and while desperately enduring it, he ran the "Purple Jade Smoke Technique" to the extreme, and the heat that lingered in this mine crazily converged towards Mu Han's body.

In a moment, the dozens of meters long cave all turned red.

At the exit of the mine, he suddenly noticed that his surroundings had become much cooler, and Mu Tietang couldn't help but get up, but found that the heat in the mine was rushing towards the cave where Mu Han was like a wave. Mu Tietang was still a little confused, and the red light from the cave entered his sight, and he couldn't help but be surprised, as soon as his figure moved, he leaped away from there, and landed at the entrance of the cave in a few steps.

Staring at it, Mu Tietang's complexion had changed greatly, and the cave was already fiery red, and even Mu Han's figure could not be distinguished.

"Senior Brother Xinghan!"

Mu Tietang shouted, but there was no response inside.

Seeing this, Mu Tietang was extremely worried, and as soon as his footsteps moved, he quickly rushed forward, but after only two or three meters in, he couldn't withstand the pressing heat wave, and had to hurriedly retreat out. I tried several more times, but even if I ran the true qi of my whole body, I didn't get into five meters.

Mu Tietang's brows furrowed, like ants on a hot nest kept turning around the entrance of the cave.

Inside the cave, Mu Han's teeth were almost crushed, and beads of sweat came out in large pieces, but as soon as they were exposed to the surface of his body, they were evaporated by the heat.

With the vigorous operation of the "Purple Jade Smoke Technique", the "Purple Void Divine Palace" was also rapidly absorbing that scorching breath, but the faster the exercise worked, the more heat surged from the outside, and it gathered with the scorching breath in the Heart Palace, as if it was endless.

No matter how hard Mu Han tried, the raging momentum of the heat was not alleviated in the slightest, every cell and every inch of nerve in his body seemed to be burned on the fire, and the indescribable severe pain surged into his heart, making Mu Han want to hit the stone wall headlong.

"Is it really going to be burned here?"

This time, Mu Han really didn't dare to believe that when he was about to be scalded to death by this heat, the "Purple Void Divine Palace" would be able to save his embarrassment again.

Mu Han desperately turned his brain, but at this moment, under the incessant baking of heat, his consciousness began to become a little drowsy, so that the speed of thinking was greatly reduced.

After a long time, Mu Han suddenly gritted his teeth and stretched into his arms, taking out the golden horn that carved the Dao pattern.

Reluctantly closing the golden horn in his palm, Mu Han once again operated the "Thunder Pole Sound Gang" at the same time, the thunder sound was agitated, and the mana rushed out of the heart palace and quickly extended to both palms.

The heat that raged wildly in Mu Han's body seemed to have found an outlet, and it roared out of Mu Han's palms like a flood of mana, and instantly penetrated into the golden horn.

"Buzz!"

In the fierce trembling sound, the Dao pattern was instantly stimulated, and brilliant golden rays shot out from Mu Han's palm.

Mu Han had already had the experience of refining the Dao pattern twice, although now he was refining the Dao pattern with fifty points, but the reason was the same. The front and back two patterns are connected into one on the arc-shaped golden horn, and fifty pairs of lines echo each other, like twin brothers.

In a matter of moments, the mana pouring into the golden horn was already extremely majestic, and the heat that accompanied the mana was even more terrifying. The extremely strong suction power was generated between fifty pairs of positive and negative lines, which in turn allowed more mana and heat to pour into the golden horn.

The heat drained, and the pain that made people go crazy was finally relieved a little.

"Whew!"

Mu Han let out a long breath, he knew that if nothing else happened, his little life should be saved, it seemed that the step just now was correct, fortunately, these days the generals have brought this unrefined Dao weapon with him, otherwise today is really dangerous.

Despite this, Mu Han did not dare to relax at all.

Under Mu Han's extreme control, the mana has always maintained a rapid momentum and injected into the golden horn, and the heat caused by the mana is also surging like a wave, endlessly. To Mu Han's surprise, this mana seemed to be inexhaustible, and it didn't decay at all after several minutes.

However, the current Mu Han didn't have the heart to delve into the reasons at all, for him, it was a good thing that mana was sufficient all the time.

If the supply of mana is not interrupted, it means that the loss of heat will not stop.

"Boom ......"

The thunder in the body is in harmony with the hum of the golden horn. After lasting for such a long time, the attraction between the front and back two Dao patterns increased several times, and the two Dao patterns with the surname of the spirit like living creatures slowly broke away from the imprint on the surface of the golden horn and gradually moved closer to the inside of the golden horn.

With this attraction involved, the mana and heat flowing into the golden horn increased again.

At this moment, Mu Han finally breathed a sigh of relief, and was finally able to shift some attention to the inside of the Heart Palace, after all, the culprit was inside.

But after a little induction, Mu Han was disappointed.

At this moment, the heart palace was still full of heat, and the originally white space was filled with a fiery red aura, and Mu Han still couldn't identify what was following the "Purple Star Vitality" in, but he faintly felt that it seemed to be extremely closely related to mana.

After a short while, it was still in vain, Mu Han had to give up, and his attention shifted to the meridians.

"Huh?"

Suddenly, Mu Han whispered in surprise in his heart, he suddenly found that the barrier between his heart palace and the twin veins of heaven and earth seemed to have disappeared without a trace, and the three of the heart palace, meridians, and hidden knots were completely connected into a perfect whole without him being aware of it at all.

"Jade Pivot Realm?"

Mu Han only felt unbelievable, and subconsciously distracted himself for two purposes, mobilizing some of the true qi in the heavenly veins to flow towards the Heart Palace. This time, Mu Han was extremely cautious, and the current situation could not help him not to be cautious, that scorching breath was still raging, and a slight negligence could lead to huge consequences.

After an instant, that bit of true qi actually entered the heart palace unimpeded.

......
