Refining the fire is not difficult to say, but it is very difficult to really implement.

The fire is self-contained, and it is difficult for Chu Duan's spiritual mind to enter it.

Refining the fire, the first step is to put your spiritual mind and the Heavenly Desolate Sword Yuan into the fire, stationed in it, and then master it, it can be said that after completing the first step, it is equivalent to the initial refining of the fire, and then it is relatively easy to completely refine it.

The tinder itself constantly released pale yellow flames, the temperature was not obvious, and there was no heat emitted, but it was really high, very terrifying, and Chu Duan's ice spirit power was constantly consumed.

The Heavenly Desolate Sword Yuan and the spiritual mind cooperated with the continuous impact of the fire, trying to invade it, and the fire instinctively resisted.

While doing it, Chu Duan took the Ice Spirit Pill from time to time to keep the power of the Ice Spirit from being consumed, and under this kind of confrontation, he continued to work hard.

The Heavenly Desolate Sword Yuan and the spiritual intent were constantly being consumed, and Chu Duan's expression was very focused, and sweat began to seep out of his forehead.

At the beginning of refining, it is best not to stop, otherwise the previous efforts will be wasted, and if you don't do well, you may be injured back.

Fortunately, the trauma suffered by the Geocentric Desolate Flame was really serious, and it turned into fire, and even resisting was just an instinct, otherwise as long as it released a more powerful flame, it would be enough to burn Chu Duan to ashes.

Chu Duan didn't dare to be distracted in the slightest, that meant death.

The Ice Spirit Pill was taken one after another, and it was consumed, and under this kind of confrontation, every flawless quality Ice Spirit Pill could not support much time.

Chu Duan pinched the fingers of the tinder, which had been covered with frost, quickly melting and replenishing, constantly fighting.

The activity of the spiritual mind is much stronger than before, and under control, it is mixed with the sword element, condensed into a small sword, and attacks again and again.

Tinder resembles a strong fortress. No matter how Chu Duan attacked, he couldn't shake it and break it.

Suddenly, Chu Duan had a whim and changed the way of attacking.

The small sword condensed from the spiritual mind mixed with the Heavenly Desolate Sword Element, like a real sword, under the control of Chu Duan's mind, performed a swordsmanship, which was the Heavenly Desolate Sword Technique.

The one-style attack was even more powerful than before, which made Chu Duan secretly happy.

He also tried to use the power of the mountain to use it. It was just that as soon as he used it, the little sword almost collapsed, and Chu Duan understood that it was because the small sword formed by the condensation of the spiritual mind and the Heavenly Desolate Sword Yuan was not strong enough to withstand the shock of the mountain.

Continue to perform the Heavenly Desolation Sword Technique, constantly attacking, and try to fuse sword styles.

Two-style fusion, three-style integration. Four-style fusion ......

In the continuous attempts, the consumption speed of the spiritual mind and the Heavenly Desolate Sword Yuan accelerated by a few points.

At present, Chu Duan's limit is to fuse the first fifteen styles into one sword.

The little sword is a little distance from the tinder. The green tendons on Chu Duan's forehead bulged, and he went all out.

The fifteen-style Heavenly Desolation Sword Technique is fused into one sword, and the power is extremely strong.

A sword breaks through the air, and the power is amazing!

Moment. It was stabbed on the tinder, and the pale yellow flame outside the tinder swayed wildly and shattered instantly. The fire was also opened, and in an instant, the broken little sword was divided into spiritual thoughts and the Heavenly Desolate Sword Yuan, and immediately followed the crack and entered the inside of the fire.

As soon as the spiritual mind entered the fire, Chu Duan felt a faint fluctuation in consciousness, which was the consciousness of the desolate flame in the center of the earth itself, which was still asleep.

Chu Duan's spiritual thoughts swept away with a strong and domineering attitude, directly defeating and absorbing the spiritual consciousness of the desolate flames in the center of the earth, and successfully leaving his spiritual thoughts in the fire and turning them into imprints.

The Heavenly Desolate Sword Yuan also penetrated into the fire, scattered, and spread all over every corner of the fire.

This is the first step of fire refining.

Chu Duan only felt that there was an intimate connection between the fire between his fingers and himself, and this connection would continue to strengthen with the passage of time and the deepening of tempering.

The power of the ice spirit on his fingers dissipated again, but Chu Duan did not mobilize, but moved his mind, controlling the fire, and the pale yellow flame burned, but it did not hurt Chu Duan's two fingers.

After initially refining the fire, Chu Duan was no longer afraid of the flames of the fire.

His spiritual mind and Heavenly Desolate Sword Yuan were almost consumed, and he hurriedly put down the fire and recovered.

When the spiritual mind and the Heavenly Desolate Sword Yuan were fully recovered, Chu Duan continued to refine, deepen refining, and further refine.

This second step is a process of slow work and meticulous work, with a long stream of water and slow running-in until it is completely refined.

Chu Duan couldn't help but rejoice that the Earth Heart Desolate Flame had been so badly traumatized and turned into fire, and even his consciousness fell into a deep sleep, otherwise, Chu Duan would not have any chance.

Even if he was lucky enough to encounter the Geocentric Desolate, there was no other way than to turn to ashes under the attack of the Geocentric Desolate.

However, there are gains and losses, refining the fire, just getting the fire, not the real core desolate, want to turn the fire back into the core desolate, it is a difficult process, it may take a long time.

Of course, if there are some suitable treasures, it can accelerate the regeneration of the fire and turn it into the core of the earth again.

In the next time, Chu Duan used everything on the refining of fire, there was no way, he had to leave here, but at present, this place was like a closed space, there was no way out, thinking about it, the only way out was very likely to enter the magma pool.

However, entering the magma pool without an ice treasure such as the Ice Cover is no different from suicide.

Chu Duan thought of a method, that is, after refining the fire, he used the power of the fire to protect himself, dived into the magma pool, and then left through the magma pool.

Therefore, the premise is to try his best to refine the fire, the more he refines, the greater the probability, and Chu Duan has to temporarily give up other cultivation and refine the fire wholeheartedly.

In addition to refining the fire, Chu Duan also dug out some red lotus seeds from the lotus pod, and found that these lotus seeds all had high temperatures, different from the lotus seeds that he usually knows, there was no lotus heart and no gaps, it was a whole round ball, trying to break through the inside, and immediately saw that there was a red viscous liquid inside, the quality was pure and flawless, very exquisite, and contained rich fire energy.

Chu Duan was even more pleasantly surprised to find that the liquid in the lotus seeds was actually useful to the fire, which could be absorbed by the fire, and the power of the fire was also slightly increased after absorption.

In other words, Chu Duan can use the energy of these lotus seeds to accelerate the recovery of the fire.

In addition to refining the fire, Chu Duan had something to do, digging lotus seeds.

There are more than fifty lotus flowers in total, and each lotus flower has a lotus pod, and there are lotus seeds in the lotus pod, more or less, under Chu Duan's collection, he quickly collected it, and he got a total of more than 6,000 lotus seeds, and the harvest is not small.

While refining, while using the energy of lotus seeds for the fire to absorb, the volume of the fire is increasing little by little, when the lotus seeds consume a hundred grains, the volume of the fire increases by about thirty percent, and the light yellow flame released has also deepened in color, but it is extremely difficult to identify.

This is a welcome step forward.

With the help of lotus seed energy, Chu Duan's refining of the fire was smoother and more efficient, and finally, after the lotus seeds consumed two thousand grains, Chu Duan completely refined the fire.

Outside the tinder in his hand, the pale yellow flame with a deepened color was introverted, and it completely entered the tinder, and the color of this tinder was brighter than before, bright yellow, and the volume also increased to the size of two soybeans.

Immediately after, under Chu Duan's spiritual thoughts, the fire slowly softened, became paralyzed, and changed its form little by little, and finally turned into a bright yellow flame the size of a candle flame, burning and swaying on Chu Duan's fingertips like an elf.

Then, this flame entered Chu Duan's finger and disappeared, and after a while, a small bright yellow flame appeared on Chu Duan's dantian.

Absorbing the energy of two thousand lotus seeds, the fire finally recovered partially and turned into flames again, but it was not yet a complete form of the Earth Desolate Flame, and using it, Chu Duan needed to consume a lot of Heavenly Desolate Sword Yuan.

"Now that you've refined, it's time to get out of here. Chu Duan said to himself, and he didn't know how long he had been in this place, in this place, he couldn't feel the passage of time at all, he could only vaguely feel that at least the past two months had passed, maybe longer.

After recovering the Heavenly Desolate Sword Yuan and Spiritual Intent, and reaching its peak, Chu Duan took out the only five remaining Ice Spirit Pills and took them, quickly transformed them into the power of the Ice Spirit, blessed himself, and then, looked down at the magma, jumped slightly, and fell.

At the moment when his body was about to touch the magma, Chu Duan activated the small Desolate Flame of the Earth's Heart, and the Heavenly Desolate Sword Yuan was injected into it, stimulating a pale yellow flame that permeated the surface of his body.

Hardly there was a sound, Chu Duan fell into the magma pool, and quickly fell downward, pale yellow flames permeating the surface of his body, resisting the high temperature of the magma and the invasion of the magma flow.

And the power of the ice spirit was running in the body, reducing the high temperature that partially penetrated, and Chu Duan accelerated to sink, and as far as the eye could see, there was only a dark red fill.

The spiritual thoughts emanated and were greatly suppressed, and even the spiritual world felt a high temperature burning.

Chu Duan had to endure this burn, using his spiritual mind to find his way, and when the sword yuan was consumed in large quantities, Chu Duan had to return the way he came, jump on the lotus flower and rest, until he recovered, and then enter again.

Rest again and again, look again and again, and constantly determine the direction.

Finally, after more than thirty times, there were several times when he encountered the Yan Snake, fortunately he returned in time, Chu Duan found the right direction, he was lucky not to encounter the Yan Snake, and he emerged from another magma pool, which was the magma pool in the belly of the cave he fell into, and the Heavenly Desolate Sword Yuan at this time was almost consumed.

Narrowly escaped death, and got another adventure, refining the fire to get the desolate flame in the center of the earth, and finally left the closed place, which made Chu Duan breathe a sigh of relief, and the whole person lay on the ground, only feeling very tired.

After resting for a while, Chu Duan got up and left the Yan Cave and hurried to the Heavenly Desolate Divine Mountain. (To be continued......)
