Ye Chen exhaled lightly and loosened his muscles. Although he had not yet practiced hand-to-hand combat with others, he could already feel the tremendous power surging in his bones and blood. He was definitely not comparable to his previous self.

"Here is the [World Burning] secret book. You must practice well. This secret book is divided into three levels, namely 'Swallowing Fire', 'Refining Fire', and 'Creating Fire'. When you practice to the third level and can create the first divine fire that burns the world, you will have truly succeeded in your practice."

The Fire-Blood Phoenix opened its mouth and swallowed the book of [Fire Phoenix Nirvana], then spat out a roll of bone of the same size and flew towards Ye Chen.

Ye Chenzhong took it and saw that the bone fragment was densely covered with many tiny words, about the size of a pinhole, but with his eyesight, he could see them clearly.

"Senior Sister Suzaku, is what you finally refined the Suzaku Flame?" Ye Chen asked, looking up.

"That's right." Fireblood Phoenix nodded and said, "What your second sister refined is the Taihuang Ancient Fire. This fire can refine all the matter and energy in the world and transform it into flame crystals. This flame crystal can replenish her energy. In other words, even the enemy's attack, all energy, including the law, can be swallowed up, and she is immune to any attack.

Ye Chen was stunned, "Doesn't that mean I'm invincible?"

"Of course not." Fire Blood Phoenix sighed softly: "For people of your realm, it is indeed invincible, but after reaching a certain realm, it is achieved that there is no energy in the body, but everything in the world is his body. He can control the power of the world and directly use the power of the world to crush everything. This is the most terrifying."

Ye Chen suddenly came to his senses.

"You can refine what kind of flame you want. You have to figure it out yourself." Fire-Blood Phoenix sighed. "You can only rely on yourself. If you can only refine the most basic ordinary flame, there is nothing you can do. This set of secrets can only be practiced once. Some people become invincible after learning it, but some people are still useless after learning it."

Ye Chen had already understood its meaning, his expression became serious. He looked down at the words on the bone fragment and began to practice the first level of the "Fire Swallowing" secret method recorded therein.

Swallowing fire means first swallowing the maximum amount of fire that the body can withstand, exercising the five internal organs, spleen and lungs, making the blood flow with fire energy, making the fire become one's own blood and the blood one's own fire.

The suffering that one needs to endure in this first step is definitely no less than the previous divine fire body refining, and may even be more terrifying.

Ye Chen started to practice meditation right away. He swallowed all the golden flames around his body into his stomach, and then tempered his heart, liver, spleen and lungs. He closed his eyes and burned and melted his blood vessels, heart, brain, eyeballs and everything else with the raging fire.

Time passes quietly...

This sitting lasted for ten years.

Ten years of time did not leave any trace on Ye Chen's body. Even the grown beard was quickly burned by the flames. Under the tempering of the flames, his plump skin became more elastic and plump, with a layer of exquisite and strong luster.

In the silent golden sea of ​​fire, Ye Chen suddenly opened his eyes, and his gaze burst out like two balls of flames, filled with terrifying divine light, as if his entire body was a ball of rage that no one dared to touch.

The light in Ye Chen's pupils gradually converged, but his whole body still exuded an unparalleled strong aura. He exhaled lightly, and a flame spurted out of his mouth. His teeth, tongue, bones, blood vessels and blood were all like a raging fire, hot and blazing, never extinguished, never silent!

His soul seemed to be a ball of flame, glowing and radiating heat!

"My body has finally completely become a body of fire." Ye Chen looked down at his skin and couldn't help but sigh. He stretched out his fingers, and a cluster of flames emerged from his fingertips, jumping with enchanting golden flames.

"Next, it's fire refining."

Ye Chen took out the bone fragment and examined it. It was still cold in the golden sea of ​​fire, like a piece of ice that would never melt. He didn't know what kind of ferocious beast the bone was cut from. "Refine the fire. Treat your body as a furnace and melt everything in your body, including bones, blood, heart, life, soul, as well as your own secrets, laws, and energy. Burn everything!"

"Finally, it will be refined into a unique flame that belongs to you alone!"

"If you are not careful, you may be completely refined and even lose your consciousness, and become just a **."

When Ye Chen saw this, he frowned, then was silent for a moment, and then slowly continued to practice.

A ball of fire suddenly gathered at the position of his heart in his body, wrapping his heart and bones, refining them like frying them. The raging flames burned his bones and heart, and it seemed as if drops of pure oil could flow out of them. This bone-eroding burning sensation drove people crazy.

Ye Chen's teeth were clenched and clacking. If his whole body had not become harder under the tempering of the flames, his teeth would have been broken. At this moment, his eyes were full of bloodshot, almost bulging out of his eye sockets, and his cheeks were twisted into a hideous shape under the great pain.

Ye Chen gritted his teeth tightly, fearing that he would not be able to go if he let go.

Refine! Refine!

Ye Chen melted all the bones, blood, and internal organs in his body in a fierce flame, burning them into ashes, along with his own vitality, soul, the laws of control, and various energies.

Even the twelve mysteries of energy were melted under the spontaneous flames.

With every thing that was melted, the flame in the body became more fierce and more powerful. After the internal organs were refined, the flame changed from a golden flame to a blood-red flame, like a strange blood, burning thickly in the body with a bloody smell.

Later, after the twelve mysteries of ice and snow, the sky, the earth, etc. were slowly melted into it, the color of the flame changed from blood red to gradually deeper, from bright yellow to dark red, and finally to purple, and then slowly turned into a rich dark black.

The twelve mysteries of energy burned fiercely in Ye Chen's body, followed by the law of the origin of wind.

Under the burning of the dark flame, this set of laws was slowly melted like a green whirlwind, gradually shrinking, and then slowly disappeared without a trace, while the temperature of the dark flame became more terrifying, and became somewhat lighter.

Ye Chen then melted the divine blood in his body. This drop of golden divine blood had been with him since the Earth era, allowing him to possess three superman modes: Ant Superman, Lightning Superman, and Sky Beast Superman. Now he can also devour the genes of three creatures for melting.

However, when reaching this level, the genetic level of the body has become unimportant. What is needed is the absolute power controlled by each individual!

At this moment, this drop of blood had melted 99% of the God's blood since he broke through to the God Emperor, and carried out the final smelting. It was unknown how long it had passed before it slowly changed from a golden liquid to a light flame, and then slowly penetrated into the dark flame.

The infiltration of this drop of flame gave the dark flame an extra layer of holy radiance. Although the pitch-black color looked somewhat hideous and terrifying, the aura it exuded was pure and soft, just like light!

Ye Chen then began to smelt the ant superman gene, followed by the lightning superman gene, and finally the celestial beast superman gene.

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

The genes of Ant-Man and Lightning Man are easier to fuse. Under this dark flame, they are instantly integrated with just a light touch.

The Beast Man gene struggled a little, but was finally slowly integrated.

Then there was the Source Crystal Grass on his body, as well as the Heavenly Dao Sutra, the Blood God Secret Art, and the previous Fire Phoenix Nirvana, as well as all the secret books he had ever learned, including the Yan God Secret Book.

Ye Chen's body was like a big furnace, burning everything to ashes.

All kinds of secret manuals were melted down and became nutrients for the dark flame. Every time a secret manual was melted, the color of the dark flame became darker. In the end, it was so dark that it seemed like a bottomless pool, like a dark cave, which was terrifying.

Ye Chen's heart entered an unprecedented state of peace.

He didn't even know if he still had a heart at this moment. He only knew that the heart that grew in him later was melted, his consciousness was melted, his soul was melted, and everything about him was melted.

Melting slowly...

It was as if it had become firewood for the dark flame, making the flame burst out even brighter.

If Ye Chen opened his eyes at this moment, he would definitely see the shocked look of the Fire-Blood Phoenix, because Ye Chen, who was sitting in the center of the golden sea of ​​fire, was burning with blazing black flames all over his body. This sticky flame with an evil aura seemed to be the most terrifying and evil thing in the world, causing the surrounding golden sea of ​​fire to automatically retreat like a tidal wave, and no one dared to approach.

Those who were unable to dodge the golden sea of ​​fire were touched by the black flames and were swallowed up by them as if they were stuck. They were quickly swallowed up by the black flames.

The black flames were like a huge monster mouth, swallowing up everything that came close.

For a long, long time.

Ye Chen slowly opened his eyes.

Under the long curved eyelashes are a pair of pitch-black pupils, as dark as a pool, with a cold and eerie luster, as if he were an ancient evil god.

When the Fire-Blood Phoenix saw these eyes, its heart skipped a beat, as if it had been struck by electricity, and it trembled uncontrollably. When it discovered this, it was even more shocked.

"You, what kind of flame is this?" The Fire Blood Phoenix looked at Ye Chen, "What on earth is inside your body that you have refined and transformed into such a weird and evil flame."

Ye Chen was stunned for a moment, then he raised his palm. A cluster of sticky black flames appeared in his palm, emitting a strange evil light. "I just melted everything in my body. I don't know how it turned into this."

The Fire-Blood Phoenix looked at him deeply, "You must have something of the Dark Demon God in you. No one else has this evil feeling except him!"
