The time to complete the task is one day, which is a hundred days for the Nether, and it takes several days to go back and forth to the black market castle in the north of the city, so Jiang Yi has plenty of time. He hurried back to the attic where he lived, then closed his room and immediately went into retreat.

While cultivating his heavenly power, he urged the Chaos Pill to collect two flames, and this time he didn't go to comprehend the laws in the Chaos Pill. Instead, he went to comprehend the "way of refining fire", he wanted to master this supernatural power in a few days, and then fused the two flames together, and immediately went out on a mission.

It's a pity that he underestimated the subtle complexity of this way of refining fire, and it took him ten days to get started, because he had studied the witchcraft of "burning the sky" for many years before, and he had a certain foundation for fire refining, otherwise it was estimated that he would not be able to get started at this moment.

After entering the house, everything was a matter of course, and thirteen days later he opened his eyes and decided to start refining fire.

He looked inward at the Fire Spirit Bead and found that there were hundreds of flames of both kinds, and a few dark red flames appeared as soon as the Fire Spirit Bead lit up, but he quickly discovered the problem - the prohibition in this room was too weak, if he practiced fire here for a long time, it was estimated that the entire house would be burned down, and then the attic would be burned into nothingness.

"Go to the Demon Slayer Pavilion!"

Jiang Yi remembered that there was a practice room in the Demon Slayer Pavilion, and the prohibition inside was very powerful, and the attacks of the Demon Slayer War King could not be broken, but it would cost battle merits, and he couldn't care so much at the moment, so he got up and strode towards the Demon Slaying Pavilion.

Walking into the second corridor on the right, you can practice the hall, there are more than a hundred secret rooms in it, all of which are for the members of the Demon Slayer Pavilion to cultivate, he chose the smallest one, set ten hours, and consumed a full hundred points of combat merit.

"Buzz!"

The ban on the practice room was opened, Jiang Yi released a flame, and the ban lit up slightly, and sure enough, there was nothing wrong. Jiang Yi released two flames respectively, and then used the method of fire refining to absorb the flames, and the flames turned into special energy into his body. Jiang Yi used to know this method of refining fire, but now the method of refining fire is more subtle, and after the two flame energies enter the body, they can easily turn into two different energies and surging towards the divine core.

The way of refining fire, the place of refining fire is in the divine core.

Fuse the two flames together in the Divine Core and release them when the time comes, and the power can be doubled. However, the flame cannot be stored in the divine core, and can only be released immediately after rapid fire refining on the spot, so only those who cultivate the laws of the fire system can refine fire, and there is more than one kind of flame that can be released.

Two completely different flame energies entered the body, followed the meridians into the dantian, and finally merged into the divine core. Jiang Yi controlled the two groups of energy to cross together, and then quickly rotated, like a Tai Chi Bagua fish, and at the same time, he controlled some heavenly power to fuse into two flames respectively, which were used to neutralize the two different energies, so that the two different flames could be fused.

The two flames of energy rotated rapidly, and the speed became faster and faster, and Jiang Yikong constantly injected some heavenly power into it. However, what made him extremely depressed was that for half an hour of refining fire, the two clouds of energy just did not fuse, and when they rotated, the two flames seemed to be entangled together, but once they stopped and separated, they were still a little resistant to each other, and water and fire were incompatible...

"Is there something wrong with this way of refining fire? I was deceived?"

Jiang Yi opened his eyes, he completely refined the fire according to the method above the way of fire refining, but now it has been half an hour, and the two flames have not fused, so he is still playing with a ball?

"Could it be that these two flames, one is extremely cold and the other is extremely hot, so they repel each other and cannot be fused at all?"

Jiang Yi scratched his head, thinking of the situation when he killed the Chaos Beast, he hesitated a little, if he couldn't fuse it, he would lose a lot, there was definitely something good in that spatial ring, otherwise the old man would not immediately agree to the exchange.

'Try again!'

Jiang Yi closed his eyes and tried again, but unfortunately after half an hour, he still couldn't fuse, if it wasn't for the problem with this fire refining method, it was that these two flames couldn't be fused at all.

"No more!"

He was a little irritable and controlled the two balls of flame energy from the divine core, ready to be thrown into the fire spirit bead. He didn't care at all, just at this time, the ninth star that was slowly circling around the divine core flew near the two flame energies, and he didn't pay attention for a while, the two flame energies were actually absorbed by the ninth star.

"Huh?"

Jiang Yi's heart was silent and his soul trembled, and he discovered a strange thing, these two flame energies entered the ninth star and transformed into two strange energies, one blue and one red, and these two energies were slowly fusing together.

"What's the situation?"

Jiang Yi used the way of refining fire to fuse for more than an hour, racking his brains and unable to fuse, as soon as he entered, the ninth star actually fused automatically? Jiang Yi thought that he had sensed it wrong, and observed for a long time until the two clouds of energy were completely fused into one mass before he opened his eyes in shock.

"Hell, this ninth star didn't merge into the Divine Core, and it still has this wonderful use? The ninth star has always been very weird, and it can also absorb Gangfeng energy, which should have a lot to do with the nameless exercises. ”

The remnant soul of the mysterious old man fell asleep, and Jiang Yi couldn't figure it out and couldn't solve it. He could only hide this doubt in his stomach, and he controlled the cloud of energy that turned blue-red from the meridians, and finally condensed in the palm of his hand.

"Whew!"

The two flames fused and turned into a blue-red flame. The moment this flame appeared, the forbidden light in the room shone endlessly, the air around was slightly curled, and the temperature was terrifyingly high, but Jiang Yi's body was immune to fire, and he didn't know how high the temperature of this flame was.

"Good!"

He was in a state of shock, and swung the flame at the wall, wanting to test the lethality of the flame against the prohibition and judge the power of the flame. As a result, as soon as the flame touched the prohibition, the forbidden light was great, and a terrifying coercion came, and the whole room was so bright that he couldn't open his eyes.

"Rub, this flame is very powerful, and it has touched the high-level prohibition of the practice room. When the flames were consumed, the forbidden light dimmed, and Jiang Yi's face was full of ecstasy.

This is really a turning of peaks and loops, the willows and flowers are bright and another village, the way of refining fire is ineffective, but the ninth star can automatically fuse flames. But if he didn't buy this supernatural secret technique, he didn't know that his ninth star was so useful...

He quickly controlled the fire spirit bead to gush out a ball of flames, this time the fire refining was too simple, the flames were converted into energy and entered the dantian, and it would automatically be absorbed by the ninth star, and then fused with a kind of energy, and the refining speed was too fast and too fast.

"This ninth star is a super fire spirit bead, and the fusion flame can be directly stored in it in the future. This star is boundless, even the flames of a hundred volcanoes can absorb it, it seems that I should find a way to find more heaven and earth strange fires! If I fuse dozens of flames, how powerful would this be?"

Jiang Yi didn't dare to imagine that at this moment, he finally knew the power of the Nameless Exercises, and the mysterious old man said that if he could collect all the seven fragments of the Fire Dragon Sword and the Instrument Spirit, he would be able to have the strength to fight against the Underworld after cultivating the Nameless Exercises to the ninth level.

He didn't believe it before, but after seeing the magic of the ninth star now, Jiang Yi inexplicably believed that if there was no problem with this exercise, it would be very powerful, so powerful that it was beyond his imagination...
