Deep underground, the tomb is pitch black, and the dazzling fire rises.

A tall fiery figure stood, his strength bulging, and the crimson fire covered his whole body, like a demon god crawling out of hell.

Flames churned, air twisted, and a suffocating heat permeated the chamber.

Kong Yu spread out his hand, and the foot-high flame compressed and solidified, faintly showing an orange-red color.

The flames turned into fireballs, suspended within a foot of thin air as his mind controlled.

His eyes widened as he stared at the fireball.

"Spin it!

The fireball seemed to be alive, understood what he meant, trembled slightly, and began to spin.

After a few breaths, the fireball whirred faster and faster.

When the fireball was about to explode, Kong Yu moved his mind and gave the fireball a traction.

The fireball flew out and slammed into the walls of the tomb, exploding in a cloud of bright sparks, leaving a few shallow cracks in the walls.

Since the breakthrough to the double internal force, Kong Yu has not stopped to rest for a while.

He was not hungry or tired, but he was a little thirsty, so after going out to find some water to drink, he continued to use milky liquid to frantically improve his internal strength.

After almost sleepless cultivation for another seven days, he finally broke through the realm again and reached the triple level of internal strength.

Overjoyed, he discovered that although the temperature of the flames had increased a bit, the range of the detached flames had not changed at all.

He could almost confirm that the ascension of the internal force realm had no effect on this.

In addition to his daily practice, he began to take a certain amount of time out to practice his fire ability.

In the past, in the outside world, although I had good reconnaissance skills, I was always worried that practicing fire abilities would be discovered.

But in this place, he didn't have to worry about his fire ability being exposed to people, let alone the loss of internal strength.

Kong Zhu found that in addition to consuming internal energy, the ability to urge flames also consumed a lot of mental energy, and the more delicate the operation, the more it consumed his spirit.

He could mimic the flames as birds, fish, and insects, but at most he could resemble them, and it was impossible to construct the details with his control.

It can also turn flames into fire knives and swords, but they are all appearances, they look very bluffing, but they are not powerful.

These operations are only a little more delicate than compressing the flames and turning them into fireballs, which can be considered rough, but they will also make him mentally tired after practicing for a long time.

After recovering his spirit, Kong Yu was pleasantly surprised to find that his controllable range of the detached flame had been slightly improved.

So he had some thoughts in his heart, and the flame out of body manipulation might be related to proficiency or mental power.

Kong Catch then spends a little longer practicing the fire ability, and he's found the best way to practice it so far.

It was a spiral-like spinning fireball, and the faster the fireball spun, the more difficult it was to control and the more it drained his mind.

Kong Zhu practiced in this way, and after only three days, he was able to control a foot and a half of flames outside his body.

Today, the fire ability has been practiced for nearly an hour, and most of the internal strength has been consumed, and the spirit is already very tired.

He was ready to practice again, so he went back to practice the Fire Burning Cloud Inner Gong as a rest.

Taking a deep breath, he almost sucked the flames covering his body into his throat.

With two dry coughs, the internal force surged, and the crimson flame pillar rose in the palm of his hand, and then slowly compressed into an orange-red fireball under the control of his mind.

The fireball began to spin, from slow to fast, with the sound of whirring wind.

The fireball spun at a rapid pace, faintly revealing a dangerous aura.

Kong Yu knew that this was just an illusion, this fireball looked very bluffing, and when he threw it out, it exploded suddenly, but it could only last less than a breath.

If the flame persists, the flame of nearly 1,000 degrees can burn a person to only a few scraps of bones.

And the flame exists for too short, and the power is at most to burn people, but not fatal.

After a time of one or twenty breaths, the fireball slowly accelerated, and now the speed of rotation was extremely terrifying, and Kong Yu could no longer control it.

He was about to throw the fireball out, but his spirit suddenly went into a trance, and the fireball paused in front of him for a moment.

The next moment,

Rumble~!

The rapidly spinning fireball exploded in front of him, and for a moment, the alarm bell rang in Kong Tuo's heart, and a sense of danger rose in his heart.

Without hesitation, the muscles on Kong Zhu's body swelled, and his whole body showed a copper color, which was the bronze statue skill.

In the blink of an eye, a dazzling light bloomed in front of him, Kong Yu closed his eyes, only to feel a strong force hit him, and his throat was suddenly sweet.

Bang!

Taking two steps back, Kong Yu opened his eyes and dispersed the flame ability on his body, and the tomb suddenly became pitch black.

He felt a pain in his chest, a trace of blood oozing from the corner of his mouth, and his clothes were even more tattered.

But Kong Zhu's eyes were extremely bright, as if he had discovered a new continent.

"Why did this fireball burst out with such power?"

Although he was in a bit of a hurry just now, he couldn't fully defend himself, so he let the power of the fireball explosion hurt him.

But the power of the fireball is also very large, enough to blow up the bones of ordinary internal force martial artists and their protectors.

Kong Zhu's originally tired spirit seemed to recover a lot in an instant, thinking about the answer to this question.

But he couldn't figure it out, so he used his internal force again, creating a spinning fireball, which accelerated to a certain level and exploded in front of him.

This time, he was ready, and the bronze statue skill had already been displayed in advance.

The fireball exploded and exploded with great force, pushing him away.

He observed the whole process carefully, but found nothing unusual.

Taking a deep breath, he created another spinning fireball, but this time he didn't let it explode in front of him, but threw it two feet away.

Two feet away, it was already out of his control.

The fireball exploded, and suddenly burst into a dazzling flame, but Kong Yu frowned slightly.

This fireball obviously has no power, at most, the high-temperature flames released can burn people, and it does not have the explosive power of the previous two fireballs.

After two experiments, he had already understood that the fireball had to explode within his control range in order to be extremely powerful.

And outside of his control, Gao Fushuai's fireball has also become mediocre.

"What's the difference between the two, that a fireball in the control area can be explosive, but not outside the control range?"

In Kong Zhu's opinion, the two fireballs are the same, the difference is that they are within the control range and outside.

And one is powerful, while the other only has an impact of a few thousand catties at most, and the difference is too big.

"How does this work?"

Kong Zhu's head was about to explode in an instant.

He also thought that he would soon become a noble master who controlled the spinning small fireball.

In a blink of an eye, he turned out to be a muscular reckless man with his sleeves rolled up.

With a small fireball in his left hand and right hand, he was a melee mage at best.
