Stretching out his hand, he was careful to bring out the new out-of-heaven fire, which was led out by "Lu Xin". Then, he skillfully threw the Devil's Foot Root into the Heavenly Flames and began the second round of refining.

The step of "refining" proceeded quickly, after all, "Lu Xin" was an immortal, and his kung fu of forging materials with fire was already extremely skillful. In addition, he had only refined Qianzhang Dust once just now, so this step was even easier for him.

After a while, the step of "refining" was completed, followed by "melting". This step is much easier than "grouping", but it is still a rather delicate and elaborate step, and if you are not careful, you will fail completely and let the material go to waste.

Now "Lu Xin" is naturally a lot more proficient in this step, after all, he already has the experience just now. Finally, in less than half a moment, the step of "melting" was completely facilitated by him, and he was slightly relieved, and he also knew that the next step was the most difficult "group".

Now this "group" step is much more difficult than before, because now the flame that has been removed from the original attribute but added the attribute of the ghost foot root wood is a new artificial flame, and if you want to integrate it into the flame that can no longer be completely called the earth fire, not only must it be contained by the earth fire itself, but also need it not to conflict with the earth attribute of thousands of feet of dust.

"Whether my method works or not, we will find out after this step. "Staring at the flame that had turned into a brown ghost foot root," Lu Xin muttered to himself with some solemnity.

"Lu Xin" knows in his heart that every "group" of every material cannot afford to fail. Because as long as it fails, it means that the plan to strengthen the earth fire has completely failed, and even the original earth fire will disappear completely. For the current material, the key to success or failure is whether his method of Mu Ketu will work, whether things will develop as he imagined, if it is biased, the consequences will be unimaginable.

After thinking silently for a while, the time seemed to be short, but in fact, "Lu Xin" had already passed countless thoughts in his heart. In the end, when he was sure that he had no more clever way, and he couldn't think of any flaws in his current method, he finally made a move.

The two hands, one on the left and one on the right, reached out respectively, controlling the earth fire and the ghost foot root flame and began to slowly move closer. The earthy yellow flames and brown flames were originally extremely quiet, but when they were less than an inch apart, the mutation suddenly appeared.

I saw that the brown flame suddenly rose a little, and it actually took the initiative to rush towards the earthy yellow flame, as if it was fierce and wanted to "eat" the earthy flame. The earthy yellow flame, on the other hand, lowered itself a little as if it were spiritual, as if it was showing weakness to the brown flame.

"Mu can overcome the soil, this phenomenon is in line with my calculations. However, I still have to be careful, otherwise if all the attributes of Qianzhangchen are destroyed by the Devil's Foot Root Flame, then everything I have done will be finished. Looking at the phenomenon that just happened, a drop of sweat quietly fell from the corner of Lu Xin's forehead, and he thought silently in his heart.

Then, the speed at which "Lu Xin" brought his hands closer together slowed down a few points, and continued to move the two flames closer to the middle. As the two flames continued to get closer, the momentum of the brown flame became stronger and stronger, and the momentum of the earthy yellow flame became weaker and weaker.

It wasn't until there was less than half an inch between the two flames that the brown flame actually took the initiative to rush towards the earthy yellow flame, and it was instantly entangled with it.

The moment the earthy yellow flame was swept away, it first fell sharply, and then it rose up as if it was fighting for its life, as if it was not convinced by the power of the brown flame.

At this moment, the intensity of the rejection and conflict between the two flames was unimaginable. I'm afraid that only "Lu Xin" himself knows how dangerous this situation is.

"Not good, could it be that my judgment was wrong, why is the reaction of the earth fire so strong?" His eyes looked at the two flames that had been entangled with great solemnity, and watched the brown and yellow constantly fighting back and forth, "Lu Xin" exclaimed, and hurriedly used his spiritual power to frantically control the flames in his hands to prevent them from happening to a greater accident.

Large drops of sweat continued to flow down from "Lu Xin's" forehead, and he could now be said to have used almost all of his ability to control fire to deal with this situation.

Fortunately, this situation did not last long, and after a short battle between the two flames, the principle of Mu Neng Ketu was manifested. As a result, the brown flames gradually gained the upper hand, while the earthy yellow flames gradually became lower, and the repulsive force between the two flames continued to shrink.

The shrinkage of the repulsion force represents the shrinking of the fire control pressure of "Lu Xin". After realizing that what he thought was not wrong, a burst of surprise first came to "Lu Xin"'s heart, and then he thought of what to do next.

Now that the power of rejection has been reduced, it is neither the earthy yellow flame nor the brown flame that should take the initiative, but "Lu Xin" himself. Now he needs to let the two flames develop in the direction he needs, mainly the earthy yellow flame, to absorb the ghostfoot root wood attribute in the brown flame, and also absorb more firepower, so that the flame power of the earth fire will be strengthened again, and the attribute will be added to it.

Half an hour later, when "Lu Xin" exhaled a deep breath of turbidity, the flames floating in front of him had completely changed from two to one, a quiet one.

This flame is still mainly earthy yellow, but it is slightly deeper than before, and it is a new earth fire that has successfully absorbed the attribute power of the ghost foot root wood.

"It seems that the time of this retreat is not short, each of these materials will take me about an hour, and the creation of earth fire is really not easy. ”

"But fortunately, now that I am strengthening the earth fire, I can distract myself and not think about the "Infinite Earth Sutra", which is quite beneficial to let go of the obsession with the "Infinite Earth Sutra". If I had been concentrating on strengthening the earth fire during this time, I would not have been able to wait until my earth fire was completed, and my obsession with the "Infinite Earth Sutra" would not have been much left. Slightly tired and muttered a few words to himself, "Lu Xin" knew that he would face difficulties and challenges for a long time next. However, he was already ready to deal with it.

In the next three months, "Lu Xin" continued to integrate new attributes into the earth fire as he had planned, and also added more flame power. Every time a new attribute is added, it is a new challenge for him, and it almost makes him sweat.

Especially when more and more properties are added to the local fire, the more difficult it is to add each new material. This increase in difficulty is far steeper than the experience and proficiency that "Lu Xin" gained in one success after another, so even if "Lu Xin" does the same thing many times, the speed is still not fast, and every time he is terrified.

During these three months, only "Lu Xin" himself knew how many difficulties he had experienced and how many dangerous crises he had experienced. And the most important thing is that every crisis has the potential to make all his efforts completely wasted and his earth fire completely disintegrate. So his heart is always hanging, and he has never felt steady.

Such a strengthened earth fire is no less than fighting with a strong man for months and countless rounds of battle. If he hadn't been holding on to a string and not relaxing, constantly alerting himself, I'm afraid he would have fallen down because of his lack of strength and energy.

One day, three months later, there were no more than a thousand materials in the secret room, but only one left. Next to this material, there is a huge ball of fire that burns brightly. This fire mass is earthy yellow, and it is very close to the real earth fire. However, its size is no less than a hundred times larger than the original earth fire, and the flame power contained in it is so strong that it is faintly comparable to the real earth fire.

"Heh......" A breath came from the dark corner of the retreat, causing the floating earthy yellow flames to flicker a few times. Then, a tired, even slightly withered face appeared in the firelight. Then appeared a slightly clumsy figure.

With such a face and such a figure, if people look at it, I am afraid they will subconsciously think of four words - the end of the year. It's a pity that the person who has such a face and figure now is not an old man, but a young man, his name is Huan Yin.

After three months of painstaking strengthening, Huan Yin has now integrated nine hundred and ninety-five materials into the earth fire. Therefore, the earth fire in the secret room now is the earth fire that is close to completion, and it is something that Huan Yin finally got after going through countless difficulties and tortures in the past three months.

It's just that in order to get this thing now, Huan Yin has paid too much, and now he is extremely tired, and he may fall down at any time. So, even the faceless ones have now been put away by him. Because he was no longer able to distract himself and support the faceless power to continue.

"There's one last one......" A hoarse voice came out of Huan Yin's mouth, accompanied by a somewhat distorted smile on his withered countenance.
