"According to my calculations, this medicine fire may have to go through five stages: gray, white, blue, purple, and gold before it can finally recover to its strongest state. At present, the power of this heavenly fire is at best a little stronger than ordinary medicinal fire real fire and the like. ”

"So, I have to find a way to go to the Medicine Fire Cave one more time?" Chu Chen shook his head helplessly, "How much True Fire does this thing need to swallow to completely restore the rules of the Medicine Palace, even if it is a disciple who has cultivated to the Spirit Spring Realm, it can only enter it three more times, in case there are not so many medicine fires in the Medicine Fire Cave, it is also a very troublesome matter." ”

"There is a place in your Medicine Palace called 'Fighting Fire Altar', which is not far from the Melting Fire Altar. It was a special place for the disciples of the Medicine Palace to practice controlling the medicine fire. You can go around and try your Heavenly Fire power, and maybe you'll be lucky enough to swallow a few Medicinal Fires, which will be much faster than catching them in the Medicinal Fire Cave. If you want this heavenly fire to completely grow to the strongest level, it is not something that can be completed in a while, take your time. ”

The little hamster thought for a moment and buckled his nose, "Anyway, with this heavenly fire protection, you shouldn't have to be afraid of other people's medicine fire anymore, and fighting against the pharmacist can be regarded as invincible." ”

Chu Chen's brows furrowed slightly, and he nodded silently.

After five days of adjusting and cultivating, Chu Chen finally completely recovered all his energy, and all his fatigue was swept away.

In fact, the benefits of refining the Heavenly Fire as one's own natal medicine fire were immediate.

Not only did the cultivation in the body become more vigorous, but the spiritual spring also seemed to have been thoroughly baptized by the heavenly fire from the inside out, and the spiritual power running in the body became more pure, thick, and dense.

Not only that, but it seems to be contaminated with the kind of ruined miè aura that is unique to heavenly fire.

Now the spiritual power in Chu Chen's body was also filled with a taste of madness, destruction, and destruction, and he saw with his own eyes that a finger of his fingers flew by, and a steel plate in front of him that was about three inches wide and more than a foot wide was completely blasted into iron powder.

Before smelting the Heavenly Fire, his fingers could only punch a round hole in the steel plate at most.

Now that his cultivation and energy had recovered, Chu Chen went to the Fighting Fire Altar of the Medicine Palace to try it as the little hamster said.

The Douhuo Altar is not far from the Melting Fire Terrace, which is also a stone platform carved from a whole piece of Refining Fire Crystal Jade, but the area is much smaller than that of the Melting Fire Terrace, and it occupies only about ten zhang in a circle.

It's just that although it occupies a small area, there are many more disciples gathered around the Fighting Fire Altar than the Melting Fire Altar. From time to time, bursts of cheers erupted from time to time, which was extremely lively.

After the initial smelting of the medicinal fire, many medicinal palace disciples still need a period of adaptation if they want to completely control the power of the medicinal fire.

After all, as the saying goes, fire and water are ruthless, and the true fire that can be selected as the natal medicine fire itself is extremely powerful, even if it has been refined, if it cannot be fully controlled, it may still cause some irreparable consequences.

The Fighting Fire Altar is a place specially built to allow students to skillfully use medicinal fire.

The rules of the Fighting Fire Arena are generally that students release their own medicinal fire, and manipulate it to fight with other medicinal fires in the void with their minds.

On the one hand, this can train the disciples to control their own medicinal fire, and on the other hand, it can also enable each student to exchange with each other the method and know-how of manipulating the medicinal fire, which has a significant effect on the disciple's early control of the medicinal fire.

As soon as I came to the altar of fighting fire, I saw the glare over the huge red stone platform.

Medicinal fires of different colors collided, entangled, annihilated, and exploded in the void, shooting out waves of brilliant firelight and qi, which were as beautiful as fireworks.

Around the Douhuo Altar, there were even good deeds that opened a betting board guessing game, inviting many disciples who watched to bet on which one of the medicinal fires would win.

The entire Douhuo Altar was full of people, as lively as a mortal street.

Seeing this scene, the corners of Chu Chen's mouth couldn't help twitching.

The three outer floors around the Fighting Fire Altar were full of people, and it was really not easy to get in.

Chu Chen struggled to squeeze to the innermost layer, and was just about to step onto the fire arena but was squeezed down by a tall and strong man.

"What's the hurry! if you want to see it, it's good-looking, don't go up, in case it is burned by those medicinal fires, it's not a joke!" The fat man turned his head and glared at Chu Chen.

"Uh...... I'm not here to see, I'm going to go in and fight. Chu Chen rubbed his temples helplessly.

"You want to go in and fight the fire too?" the big man looked him up and down a few times, glanced at the corner of his mouth, and his fat body reluctantly moved out of a position that only allowed one person to pass through guò.

"Thank you, brother. Chu Chen nodded, and his figure turned into a gray shadow and jumped onto the fire fighting altar about half a zhang high.

"Huh, how did this guy get there?"

The big man who gave up his seat to Chu Chen was stunned for a moment. Chu Chen's speed was so fast that he couldn't see his figure clearly at all. It seemed that only a shadow flashed in front of him, and when he looked at it again, he had already gone up to the altar of fire.

Am I mistaken?

The big man rubbed his eyes, and his face was suspicious.

At this time, there were about a dozen students fighting each other in pairs on the fire fighting altar.

From time to time, you can see some flames being blasted away by the powerful force, turning into bits of fluorescent light and dissipating in the air, and after a while, they reappear in another place, flickering bright again to join the battle group.

Chu Chen glanced at it, stood on the edge of the Fighting Fire Altar and exhaled slightly, and ignited his own medicinal fire with a "boom". Suddenly, a light gray flame rose up, swaying in the void.

"Hmm, how is there a gray fire here...... Isn't that a waste fire?"

Among the true flames full of various brilliant colors, Chu Chen's light gray flames were extremely conspicuous. For no other reason, this light gray hue is too obvious.

At this time, the flames fighting each other on the altar of the fire were of various colors. Red, orange, yellow, green, blue, purple, black and white have all colors, except for the gray flame.

All flames, regardless of their rank, are extremely pure and dazzling in color alone.

In the world of medicinal fire, gray only represents one meaning: that is, the waste fire that contains too many impurities to be used at all! The higher the quality of the medicinal fire, the less impurities it has, and the purer the color. It's almost become a law.

Therefore, seeing Chu Chen's gray flames rising up, the disciples who had gathered around the Fighting Fire Altar to watch suddenly burst into exclamations. It is a well-known fact that waste fire cannot be refined.
