After all, it was the first time to refine the spiritual fire, Tang Bohu didn't have the slightest experience, although these Xuan Lao understood, but Tang Bohu could only experience it himself.

And after this initial experience, Tang Bohu has been made worse than dead, which is Tang Bohu's deep experience.

This was the first time he had been so close, in contact with the spiritual fire that no one controlled, and although there was some strange novelty in his heart, it was more of an uneasiness and apprehension.

In this case, if the blood-colored cuticle on the arm cannot be repaired, then he Tang Bohu may turn into a pile of ashes in just a few seconds.

Beneath the blood-colored stratum corneum, sweat dripped from Tang Bohu's forehead and fell into his eyes.

Although it was sour and painful, he didn't even dare to blink his eyes once, pursed his mouth tightly, and his palms grabbed inch by inch in the cyan flames.

While looking for the wisp of the ancient flame of the Qinghe Spiritual Fire, Tang Bohu couldn't help but feel shocked and amazed by the high temperature of this spiritual fire.

The high temperature it contained was far beyond Tang Bohu's expectations, even if it was fully prepared, the terrifying high temperature carried by the Qinghe Spirit Ancient Fire still slowly penetrated the blood-colored cuticle, as well as the defense of the Qinghe Energy Shield.

Let Tang Bohu, who had to hide under him, his skin was as red as the red-hot soldering iron.

Gritting his teeth and enduring the intense burning pain, Tang Bo quickly glanced around from the corner of his tiger's eyes, but he was a little shocked to find.

The surrounding caves, which were originally not too spacious, have now been nearly doubled.

Moreover, at this time, the Qinghe Spirit Ancient Fire also seemed to be aware of Tang Bohu's actions, and suddenly the cyan flames churned violently.

In the surrounding space, the energy of heaven and earth contained in it was also like a riot at this moment.

The colorful mottled energy flows slowly, like a colorful river, which is extremely dazzling.

Colorful mottled energy hovered around the Qinghe Spirit Ancient Fire, and occasionally a cluster of flames fluttered up.

Suddenly, these ring-shaped mottled energy circles were like pies that had been bitten by dogs, with few corners and edges.

With the sudden riot of the Qinghe Spirit Ancient Fire, the already terrifying temperature in the cave immediately skyrocketed again.

And the surrounding caves, in the sudden surge of high temperatures, began to crack rapidly, and huge cracks quietly spread.

In just a moment, it was all over the cave, and looking at the damaged interior, if it weren't for the support of Xuan Lao, I am afraid it would have collapsed long ago.

"It's really a terrifying destructive power, if you throw it in a city, I'm afraid that in an hour, a large city can be burned to ruins, right?"

Looking at the inside of the cave, which had changed greatly in just a moment, a palpitation appeared on Tang Bohu's face, and he muttered, and then moved his gaze to Xuan Lao.

At this time, Xuan Lao was staring at the cyan flame's every move with a nervous face, and felt Tang Bohu looking at him, and his tense old face was slightly soft, showing a comforting smile at him.

Nodding at Xuan Lao with a forced smile, Tang Bohu's eyebrows suddenly raised, and a touch of ecstasy surged up on his face, and he hurriedly turned his head and stared at the cyan flames.

The arm, covered in the blood-colored cuticle, was in the cyan flames, and it was like a mad frenzy.

After an instant, the rapidly dancing arm suddenly stiffened, and a smile gradually climbed up the corner of Tang Bohu's mouth.

Looking at Tang Bohu's expression from the side, Xuan Lao was also greatly relieved, although the blood armor condensed by the Blood Soul Saint Pill was strong, but it could not withstand the long-term spiritual fire.

If the blood armor was volatilized due to the exhaustion of energy, then Tang Bohu's devouring spiritual fire this time would have to be declared a complete failure.

Grabbing a touch of the palm of his hand, it was like a substance-like object, Tang Bohu gritted his teeth, endured the hot pain from the palm of his hand, and slowly pulled his arm out of the cyan flames.

When the arm was withdrawn from the cyan flames, in Shangguan Yu's palm, a wisp of liquid-like thing like cyan magma squirmed slightly in it.

"Is this the spark of the Qinghe Spirit Ancient Fire?"

Staring at the wisp of cyan magma released in his hand, with a terrifying temperature, Tang Bohu blinked his eyes and muttered softly.

As the flame was pulled out of the Qinghe Spirit Ancient Heart Fire, the huge cyan flame in front of him suddenly gradually shrank.

A moment later, it turned into a thin cyan flame and burrowed into the cyan magma strip in Tang Bohu's palm.

"This is the origin of the Qinghe Spirit Ancient Fire, don't underestimate its volume, when it was first formed, it should have been as huge as half a mountain, but after thousands of years of training on the earth, the volume is getting smaller and smaller. ”

And when its volume is compressed to the size of a palm, it can form a little fire spirit, and at this time, it can really be called spiritual fire. ”

"You can imagine how devastating it would be if the terrifying energy absorbed for thousands of years was compressed into such a thumb-sized magma bar, and if it exploded completely. ”

"And to put it bluntly, at that time, even if it was a Spirit Sect Realm powerhouse, in the face of such a sudden burst of power, there was definitely only one end......"

Xuan Lao stared at the cyan magma in Tang Bohu's palm, which was like a worm, and said softly: "That's the fall!"

With a long exhale, Tang Bohu nodded silently, carefully holding the cyan magma strip.

In the palm of his hand, due to the terrifying high temperature contained in the magma strip, the thick blood-colored cuticle is melting at a terrifying speed.

"What's next?" Tang Bohu blinked and muttered.

"Swallow it. ”

The white flames above Xuan Lao's body trembled irrepressibly a few times, and there was still a little tremor in the old man's voice who was trying to maintain his composure.

The step that Tang Bohu has to take now is the most dangerous step when devouring the spiritual fire, no matter how hard the human body is, the inside of the body is always the most vulnerable part.

In the human body, not to mention the spiritual fire with destructive power, even if you get into something, you can make a strong person unable to survive or die.

Hearing Xuan Lao's words, Tang Bohu clenched the palm of the Qinghe Spirit Ancient Fire Flame, and trembled a few times imperceptibly.

In the dark eyes that hung his head slightly, he stared at the slowly wriggling fire, and his black and white eyes flickered with struggle.
