After taking the Escape Pill, Su Che used the Escape Technique to sneak into the stone wall behind him, and then sank down the stone wall to a depth of more than thirty zhang, bypassing the lava river from below, and diving towards the small island in the lake.

When diving through the bottom of the lava river, he could still feel the extremely high temperature, but it had no effect on an immortal cultivator like Su Che, and he could withstand it with only his True Qi Protective Body.

Following Lao Hei's guidance, Su Che came to the bottom of the black island, and was about to climb up, but heard Lao Hei say: "Master, that black island is actually a complete black boulder, and my detection ability can't see through it, so I can't be sure if your retreat technique can be effective, so you have to be slower when you ascend." ”

Su Che responded, naturally knowing that if the Escape Technique didn't work on the black boulder, he would bump into it with a pop and break his head and bleed......

Slowing down the speed of retreat, Su Che cautiously climbed upward, and as the temperature of the ground rose sharply, he soon touched the bottom of the black boulder. Su Che raised his hand to touch it, but felt the real hardness and heaviness.

"It really doesn't work. ”

The art of retreat can treat the earth and stone as nothing, and being able to touch it at this moment shows that this black boulder is very special, different from the natural things in the earth.

Su Che first took out his magic sword and dug a crypt in the soil layer at the bottom of the black boulder, so that even if the medicinal power of the Retreat Pill failed after a while, he would still have enough space to move around at will.

Then, he used the magic sword to cut a few times at the black boulder above, and the scandium and scandium were strong, and not a single stone chip was cut off, but the magic sword in his hand was seriously damaged. Obviously, his magic weapon flying sword is far inferior to this stone in terms of hardness.

"Good baby!"

The magic sword was damaged, but Su Che was very happy, because the attempt just now could at least prove that this black boulder belonged to some kind of high-strength refining material...... It is harder than the finished magic sword, and it is conceivable that the innate grade of this refining material must not be low.

Such a large boulder, to say the least, has hundreds of thousands of catties, if it is really a high-grade refining material, then it will be rich!

At the same time, Su Che was secretly worried: "This guy is so hard, but he doesn't have the right tools to cut it, do you have to take it away whole?"

Sensing Su Che's thoughts, Lao Hei replied: "No, master, such a big stone, I can't put it in the Immortal Prison...... At the very least, the current capacity is certainly not possible. ”

Cut and cut and can't move, collect and can't take away, and the magic weapon of the Lingqi on it is guarded by the red-tailed fox and the flame monster...... Could it be that this time I searched for treasures, did I really want to find nothing?

Of course, Su Che was extremely unwilling, and his palm subconsciously pressed against the black boulder, revealing a reluctant look.

But he didn't want to, a cool feeling penetrated into his palm, making Su Che refreshed, and for an instant, he completely ignored the high temperature baking caused by the magma above.

"It's so comfortable!"

Su Che praised in his heart, and suddenly remembered the warm current of vitality created by the Immortal Prison, one cold and one warm, both of which made people feel comfortable...... So, a flash of inspiration flashed in his mind, and he shouted in his heart: "Old Hei, pass on some vitality!"

"Okay, master. ”

After a few breaths, the vitality transformed by Lao Hei was transmitted from the center of his eyebrows, and Su Che consciously guided the warm current of vitality towards his shoulder, and at the same time, the clear current from his palm was also directed towards his shoulder......

"Master, be careful. Lao Hei was tense in the immortal prison, his black hair trembled, and he couldn't help but be nervous about his master's adventurous attempts.

"It's okay, I trust my instincts. ”

In many cases, Su Che is indeed bold and adventurous......

Finally, one cold and one warm, two strands of energy as thin as a hair converged together at the Yunmen Acupoint at Su Che's shoulder blades...... As soon as they come into contact, they blend together like water and milk, and there is almost no reaction process.

"One cold and one warm, one yin and one yang, I'm really ......"

Su Che was a little complacent, but he didn't want to, the two energies that fused with each other came into contact with the true qi in the meridians, and this time, something that surprised Su Che appeared.

With a bang, the true qi in the body suddenly boiled, as if a burning torch had fallen into a pond filled with fire oil, and the flames that rushed to the sky suddenly soared, unstoppable!

"Ahh

Su Che screamed, and the palm on the black stone shrank back like an electric shock, and in the immortal prison, Lao Hei also hurriedly braked the teleportation of his life force......

"Master, how are you?" called out the old black in alarm.

Su Che didn't care to answer him, and immediately sat cross-legged on the ground, trying his best to adjust his internal breath, trying to control the true qi in the meridians and dantian that had boiled to the earth.

"Control...... I can't stop it!"

WhewW......

The inside of the body seemed to be on fire, and the blood and water were also boiling, not to mention controlling the true qi, even his sitting posture, Su Che couldn't control it, and he fell to the ground with a plop, his fingers couldn't move, and he completely lost his ability to move.

"It's okay, it's okay, I trust my instincts, it's okay, it's not wrong......"

At this moment, Su Che endured the pain of frying and frying, and he was still clinging to his so-called intuition in his heart. Just now, there was a very clear feeling that there could be no mistake......

However, intuition is such an ethereal thing, can it really be believed?

"What should I do? What can I do?" Lao Hei was in a hurry in the immortal prison, but he didn't dare to help indiscriminately, lest he make mistakes in the chaos, and the more wrong he was, the more chaotic he became.

Call~~~

After a while, Su Che faced a terrible situation inside and outside, because, not only was the true qi in his body boiling to the point of exploding, but at this time, the intense fire qi from the underground fire vein above his head was attracted for some reason, hulala, and the scorching fire qi penetrated everywhere, along Su Che's mouth and nose, sweat pores, and acupuncture points all over his body, and penetrated into it unobstructed.

"It's okay, it's definitely going to be okay!"

It was already a situation of internal and external suffering, and Su Che was still clinging to his instincts, like a stubborn madman.

The fire qi entered the body, gradually thickening, calcining every cell in Su Che's body, of course, including the already boiling true qi, and the boundless pain hit like a tide. Fortunately, the Immortal Hell Pagoda in his mind was like a needle of the sea god, silently guarding Su Che's consciousness and always staying awake.

At this moment, this situation of converging fire qi reminded Su Che of the first time he swallowed the Retreat Pill and hit the middle stage of Qi cultivation in the depths of the ground, and he suddenly had a trace of realization in his heart.

"Old Black, help me up and resist the black stone...... There is also the Earth Spirit Pill, the vitality ......"

The thought sent by Su Che seemed a little incoherent, but Lao Hei still understood, and immediately transformed into a heavenly demon form and drilled out of the immortal prison, helped Su Che up from the ground with the power of the heavenly demon, and helped him press his hands on the black boulder, and took out an earth spirit pill from the immortal prison for Su Che to take, and after that, a steady stream of vitality was conveyed to the past......

The two energies, one cold and one warm, reappeared, or converged and fused in the 'Cloud Gate Acupoint', igniting the true qi to a greater extent and aggravating Su Che's pain to a greater extent.

What does this do?

Adding fuel to the fire and wanting to commit suicide?

Of course not!

When this kind of suffering reaches a certain apex and transcends a certain limit, the true qi and the fire qi no longer suffer each other, but smoothly merge together, and begin to burn the original earth-based characteristics of the true qi within it, which means that Su Che's true qi surname has begun to transform towards the fire system.

At the same time, Su Che's cultivation strength was also growing exponentially, and the medicinal power of an Earth Spirit Pill originally took three days to absorb and digest, but now, after only three hours, it was consumed.

Lao Hei had already figured out the reason for this, and without Su Che's instructions, he took out the second Earth Spirit Pill in time and gave it to Su Che.

Three hours later, it was a third......

In this way, a total of twenty Earth Spirit Pills were taken, and five days passed in a flash. In the crypt, Su Che slowly retracted, and an orange-red flame brilliance flashed in his eyes.

Repair for a big rise!

Tossing like this a few more times, it seems that you can advance to the fifth level of qi training......

"Fire, earth, and wood are three spiritual roots...... Unexpectedly, tossing and tossing, until now I have embarked on the road of the fire system with the heaviest tendency. ”

Su Che smiled silently, silently sighing that the arrangement of fate was really wonderful.

Yes, after this rather inexplicable toss, Su Che actually succeeded in absorbing a large amount of fire qi from the underground fire vein, forcibly changed the true qi surname, and changed from the characteristics of the earth system to the characteristics of the fire system, from now on, if he cultivates the fire system exercises, it will naturally be more suitable.

Forcibly reversing the true qi surname, if this kind of thing is said, even the great cultivator of the Yuan Infant Cultivation will find it incredible. It is said that if a person wants to change his true qi and surname, he must go through a process of re-cultivation after dispersing his exercises, and if it is not necessary, no one will be so nonsense.

However, when he came to Su Che, not only did he not need to disperse his skills, but he could also greatly improve his cultivation on the original basis, which was indeed unheard of.

Su Che and Lao Hei knew that the fundamental reason for being able to do this was, of course, two wonderful energies, one cold and one warm. It is already known that the warm current of the Immortal Hell is the vitality that can nourish all things, so what is the cool air flow from the black boulder?
