"Puny brat, where are you going to escape?"

The Black Turtle King swallowed the top-grade earth-grade silver spear and shattered the tall treasure cliff, then he quickly chased after Ye Chenfeng.

Besides the two golden-armored puppets protecting the cliff, there was no more danger in the stone forest. Ye Zichen flapped his Golden Roc wings quickly, then flew at a high speed for two hours before arriving at the end of the stone forest.

"Phew, I'm going to barge into the path of fire."

Ye Zichen guessed that since the Black Turtle King had survived the thunder tribulation, it was most likely that he would choose the path of thunder. Therefore, he had no choice but to enter the path of fire and try his best not to fight the Black Turtle King.

"What a high temperature."

He noticed that the two sides of the road were burning with raging flames. The high temperature caused his skin to hurt, while a large amount of fire energy passed through the pores of his body and rushed into his body, as if it wanted to melt him.

"Primordial Divine Wood, devour!"

The Divine Primal Chaos Wood could devour all kinds of energy. Ye Zichen could feel that the flame power that drilled into his body was increasing, while the pain was becoming more and more intense. He quickly controlled the Divine Primal Chaos Wood to devour the flame power within his body.

With the Primal Chaos Wood devouring him, the pressure on Ye Zichen was greatly reduced. He flashed and quickly ran towards the end of the road of flames.

"What's that?"

Ye Zichen quickly moved for the time of one incense stick's worth of time. He suddenly felt a huge pressure from above him. A meteor with a long fiery tail cut through the scorching space, locked onto Ye Chenfeng, and plummeted towards him at an extremely fast speed.

"Blood dragon fusion, 450,000 jins of strength."

There was nowhere for him to run. Ye Chenfeng decisively merged with the blood dragon's power and unleashed a terrifying power. He held the Great Heavenly Sword and charged forward.

"Rumble!"

When Ye Zichen's sword attack, which weighed 450,000 pounds, struck the fiery meteor, it was as if it hit an unstoppable piece of black iron. Waves of powerful explosive power exploded on the surface of the fiery meteor.

The terrifying explosive force rushed into Ye Zichen's arm through the Great Heavenly Sword, causing his arm to be injured. He continuously retreated, while a large amount of blood uncontrollably spurted out.

"Perfection Sword Force!"

Ye Zichen's body was continuously pushed back by the fire meteor, then he shouted loudly as the Perfection Sword Force sprayed out from his body and fused into the Great Heavenly Sword. He continued to increase the attack power of the Great Heavenly Sword and focused on attacking the fire meteor.

"Kacha kacha …"

The moment Ye Zichen used all his strength to resist the fiery meteors, a series of shattering sounds rang out. The fiery meteors were attacked by both Perfection Sword Force and 450,000 pounds of force, causing cracks to appear on the surface of the fiery meteors.

"Break!"

Ye Zichen pushed himself to the limit and released all the power in his body. He held the Great Heavenly Sword tightly in his hands and pierced through the fiery meteor, shattering it.

"Huff, huff. The power of these fiery meteors is simply too terrifying."

Although Ye Zichen had shattered the fiery meteor, both of his arms had lost a lot of blood due to the fiery meteor's power. The qi and blood in his body tumbled, causing him to consume a large amount of energy.

"It looks like with my current strength, wanting to pass this road of fire is no small feat."

Feeling the difficulty of the path of fire, Ye Zichen hesitated for a moment, then took out a fist-sized Magical Crystal Bone. He was prepared to refine the Magical Crystal Bone, refine his bones, and further increase his strength.

If he could cultivate the Bone Forging stage to the Great Perfection Stage, then his physical strength would reach 550,000 Jin, which was enough to deal with the many dangers within the path of fire.

"Mm, why is the demonic energy in this magicite gem so weak?"

When Ye Zichen released the magical energy from the demon crystal bone, he discovered to his surprise that the demonic energy contained within the demon crystal bone was extremely weak, and was not enough to pose any threat to him.

"Soul Devouring Spell, Devour!"

As the mind devoured the demonic energy, Ye Zichen immediately used the Soul Devouring Secret Art to devour the pure energy contained within the demon crystal bone.

The magicite gem that Ye Chen had consumed was the size of a fist. The energy it contained far exceeded the one that Mo Yuyan had given him.

As the large amount of pure energy fused into his body, Ye Chenfeng clenched his teeth and endured the pain. He slowly pushed the energy through his flesh and blood, forcefully pressing it into his bones to temper the bones in his body.

"Mm. Why is the effect of magicite gems on the body so much weaker?" Ye Chenfeng clenched his teeth, and used all his strength to temper his body, only to discover that the effects of the Magical Crystal Bones were far less than the first two times. "Could it be that my physical body has developed an antibody against the Magical Crystal Bones?"

Thinking of the possibilities, Ye Chenfeng's thoughts raced as he thought of a solution.

He really could not afford to waste too much time on the path of fire. If he allowed the Black Turtle King to rush out of the path of lightning ahead of time, he would lose the initiative and be put into a passive state.

"Thunder can speed up the body tempering, I wonder if fire can do it?"

Ye Zichen took a deep breath and decided to take the risk. He controlled the Primal Chaos Divine Wood to stop devouring it and circulated his six meridians' astral energy, slowly compressing the flame energy that invaded his body into his bones.

Every time a sliver of flame power was pressed into his bones, Ye Chenfeng would endure the pain of his body being burnt. It was extremely painful, but the effect was very obvious.

After confirming that the power of fire could truly speed up the process of tempering his bones, Ye Chenfeng relied on his unyielding heart and endured the torment of the flames to temper his body.

Time passed slowly amidst the immense pain.

Seventy percent of the Bone Forging stage, eighty percent, ninety percent …

Ye Zichen painstakingly trained on the path of fire for more than six hours, before fusing the fist-sized Magical Crystal Bones into his bones. Then, his physical strength increased explosively to five hundred thousand pounds.

Ye Zichen did not stop after refining the demon crystal bone. He immediately took out the last fist-sized demon crystal bone, then devoured the demon energy and continued to refine it.

When Ye Chenfeng had refined more than half of the energy contained within the demon crystal bone, he finally refined all of the bones in his body to perfection. Every bone was shining like crystals, and the strength of his body soared once again.

"Bone like a crystal, invincible and all-conquering. This is the performance of someone at the peak of the Bone Forging stage."

Feeling the changes in his entire skeleton, as well as the increase in his physical strength to 550,000 kg, Ye Zichen let out a long sigh and punched the scorching air.

"Rumble!"

After throwing out that punch, the fist power that had been compressed to its limit exploded into layers of flames, shattering a fiery red huge rock not far away.

"With my current physical strength, I should be able to easily shatter a fiery meteor."

After reaching the Bone Forging stage, Ye Chenfeng did not waste any more time. He summoned his Golden Roc Wings, causing bursts of heat waves, and quickly flew towards the end of the path of fire.

While he was flying, a fiery meteor appeared in the fiery red sky. Carrying a powerful impact, it shot towards him.
