The originally quiet underground flame cave became lively because Huo Yuxiang and others searched for Ling Yun everywhere.

From time to time, various fighting sounds of Huo Yuxiang and others with the monsters in the Flame Cave sounded.

Between these people, Ling Yun quietly hangs between the magma in the magma pond.

The Fire Heart is constantly refining, and even when the Heaven-Swallowing Furnace is turned on, the Fire Heart is refining quite slowly.

Ling Yun knew that the taboo in the martial arts path was to be quick success and instant benefits.

So he wasn't too anxious.

Moreover, the slower the refining speed, it can also be shown in disguise from another perspective that the fire heart is indeed extraordinary.

"What? This kid's refining speed is too fast? Just the fire heart he refined in these few breaths, it will take less to say how many days will it take to put the rest of the warriors?"

When Ling Yun was not very satisfied with his refining speed, Yanhuo Tianzun was shocked.

The heart of fire is extremely violent and extremely difficult to refine.

Even some disciples with excellent talent may take a lot of time to refine a trace of Fire Heart, but Ling Yun seems to be an exception. Refining Fire Heart is like no obstacle, even if it is the Fire Heavenly Lord is not surprised.

"This kid's physique seems to be very special? And he seems to have mastered some very powerful secret techniques?"

"Just a mere seventh-level warrior in the martial arts realm, can he do this? If this kid grows up in the future, he will definitely be a dragon and a phoenix among people."

Yanhuo Tianzun narrowed his eyes slightly, but his eyes looking at Ling Yun became deeper and curious.

However, Ling Yun was obviously unaware of these thoughts of the Yanhuo Tianzun.

As the fire heart continued to be refined, the fire aura continued to run around his body.

His limbs, bones, extraordinary meridians, and internal organs were burned by the power of fire, as if they were about to burn.

It was precisely because of this that Ling Yun's expression became painful.

But Ling Yun did not give up at all and gritted his teeth and persevered.

Hard work pays off.

With Ling Yun's unremitting persistence, Ling Yun's body finally began to adapt to the violent flame aura. The burning pain gradually eased, and then the trace of flame aura began to constantly merge with the spiritual energy in Ling Yun's body.

Not only did they merge together, but they also continued to pour into Lingyun's skin and every part of his body along with the spiritual energy, and finally all gathered in his dantian.

At this moment, Ling Yun felt that the spiritual power emitted from his dantian turned red. Not only that, the red spiritual power was several times stronger than the previous spiritual power.

"Tsk tsk, the absorption and refining of just a few breaths actually strengthened my spiritual power several times. The effect brought by the Fire Heart is so significant."

Ling Yun smashed his mouth, and his face, which had been painful before, has been replaced by a smile at this moment.

This also shows that the so-called Fire Heavenly Lord did not lie to him.

"No matter what, continue to refine and absorb, and you must improve your martial arts cultivation as much as possible in the shortest time."

"Huo Yuxiang, Ouyang Xun, Jiang Ruoxue, and others who want to kill me? Just wait for me to take my life."

Lingyun's heart is full of thoughts and his whole body is full of fighting spirit.

Immediately afterwards, he worked hard to calm his energy and concentrate his mind, completely empty his mind, and refine this fire heart in the best state.

Gradually, Ling Yun fell into the state of emptiness and brightness that he had entered before.

The mind is as clear as empty, and everything is empty and bright.

This is the best state for a warrior to practice.

With this state of occurrence, Ling Yun's body's refining and absorption speed of the Fire Heart actually accelerated a little more.

"What? The realm of emptiness and brightness? This son is actually... so extraordinary."

The eyes of the Fire Heavenly Lord were shining with splendor.

Even if he dreamed of martial arts cultivation in this state of emptiness and brightness, he never expected that such a young boy would enter as soon as he said he could enter?

What does this mean?

Does this kid have extraordinary talent?

This shows that this kid's future is limitless.

"Why did I feel the taste of that person in this kid? Could this kid be like that person in the future..."

A towering figure couldn't help but surged in love in Yanhuo Tianzun's mind. Even if the figure only appeared in his mind, it made Yanhuo Tianzun's face full of horror and fear.

Next, time is lost.

In the blink of an eye, it disappeared for three days.

Within these three days, as Ling Yun's body continuously refined the fire heart, a thick layer of red light continued to shine in Ling Yun's body.

Whether it is meridians, bones, or the skin of various organs, they have been greatly strengthened.

Of course, these are not the most important ones.

More importantly, after spending all his efforts on refining these three days, Ling Yun finally felt a sign of a breakthrough.

The thick barrier of realm that was invisible and intangible before, and could only be understood, has become weaker and weaker at this moment, and even the barrier of the entire realm becomes looser and looser, as if it is about to be broken at any time.

Such signs of breakthrough also made Ling Yun come back to his senses from the realm of emptiness and brightness.

Ling Yun licked his lips, his eyes hot: "Raise me."

What he needs most now is to improve his martial arts cultivation. This time, there are signs of breakthroughs. How could he easily miss this great opportunity?

So, without hesitation, he activated the red spiritual power that had been strengthened countless times in his body, and spared no effort to rush up to the barrier of the realm.

The violent impact made Ling Yun's body tremble for a moment.

If it were in the past, such a barrier of realm would be indestructible and extremely difficult to overcome. But this time, the barrier of realm would be like a thin piece of white paper, and with a light poke, it would be broken directly.

At this moment, the red spiritual power in the body flowed wildly, and the red luster became brighter.

Bang.

A momentum surged into the sky on the surface of his body. With this momentum soaring, Ling Yun's martial arts cultivation finally stepped into the late stage of the seventh level of the earth's martial arts realm from the middle stage of the seventh level of the earth's martial arts realm in one fell swoop.

"Cool."

The moment he broke through, Ling Yun suddenly felt a sense of pleasure as if he was leaping over the dragon gate.

However, even though he was happy, Ling Yun's expression soon calmed down again.

"The late stage of the seventh level of the Earth Martial Arts is still too weak. It is probably still difficult to meet Huo Yuxiang and others. You can't stop, continue to refine and continue to make breakthroughs."

Ling Yun made up his mind and rays of light burst out from his eyes.

He had no intention of staying, and continued to activate the Heaven-Swallowing Furnace, and continued to refine the remaining Fire Heart as quickly as possible.

"Not arrogant or impatient, neither humble or arrogant, calm and composed, this boy's mind is so amazing. A genius is really a genius."
