The small cloud of earthy yellow flames floating in front of "Lu Xin" at this moment was naturally the earth fire that he had created by himself after comprehending the true source power of the flames. However, this small flame is not exactly called an earth fire now, it is only a little stronger than the tinder, and it is quite appropriate to describe it as a "flame".

But it can also be seen that the current mass of earth fire is much stronger than when "Lu Xin" created it. This is naturally related to the recent ascension of "Lu Xin's" cultivation, and secondly, it is also inseparable from the fact that "Lu Xin" has always placed it in the Fox Ding and slowly strengthened it.

"Hey, the speed is still too slow, if it goes on like this, even if I really reach the point where I can step into the earth to cultivate, you still can't reach the level I want, and you can't be regarded as a real Dacheng realm." There was a slight depth of brilliance flashing in his eyes, and Lu Xin looked at the flames the size of a baby's fist in front of him, and finally shook his head a little helplessly.

Since the earth fire was generated, in fact, "Lu Xin" has been paying attention to and strengthening the earth fire in his body all the time. It's just that the more he cares, the more he feels the difficulty of creating out of thin air. Even if he had completely created the prototype of the Earth Fire, it would be so difficult to strengthen it to the fullest, at least relying on his subtle and repeated strengthening, he didn't know what year and month he would have to wait until to do it.

In fact, "Lu Xin" finally made up his mind to strengthen the earth fire in a special retreat, and relied on the methods he thought of to cultivate it to perfection in a short period of time, and it was precisely because he discovered that the strengthening of the earth fire was not as simple as he imagined before.

And the method that "Lu Xin" came up with, although it still mainly relied on the flame true source power to create, also used many materials floating around him, and also added his understanding of materials as an instrument immortal to a considerable extent, as well as his attainments in knowing materials. So generally speaking, this time the strengthening of the earth fire is not only a kind of promotion and cultivation for "Lu Xin", but also a bit similar to refining weapons.

Such an approach is naturally a unique way. If he can succeed, he will be able to make "Lu Xin" get his wish in a short period of time and get the real Dacheng earth fire he wants. However, the success rate of this is probably not high, and it can even be said that it is extremely risky. Because no one has ever created a flame like this, such a method is completely deduced by "Lu Xin" himself with experience and understanding, and no one has ever really witnessed whether he can succeed or not.

It's just that the personality of "Lu Xin" is like this, he knows that cultivation is difficult, and if he is timid, he will not be able to do anything, let alone talk about anything to surpass others. He has cultivated the Tao in this life so far, and he has been born and cultivated, but the most important thing is to rely on his persistent cultivation heart, as well as his extraordinary understanding and courage. "Lu Xin" has never been afraid of failure, he is only afraid of his stagnation. And in order to progress, as long as it is the method he identifies, even if it is nine deaths and a lifetime, he will not hesitate to implement it.

"As long as these materials are added to the earth fire one by one, if the earth fire does not disintegrate because of this, then my earth fire will be completely completed because of the power of these materials and the more flame power I convey. But if it fails......" muttered to himself, "Lu Xin" suddenly smiled bitterly and did not continue. He knew that if he failed, the best result would be to completely destroy the earth fire he had created with great difficulty, and everything he had worked on before would be in vain, and all things related to earth fire would have to start all over again.

Without thinking about it any more, Lu Xin's face soon had a look of determination, and then he opened his mouth again and spit out, and a blood-red flame surged out, floating to the right of the earthy yellow flame.

The blood-red flame is naturally the fire flowing out of the sky, and this is also what "Lu Xin" wants to use to strengthen the fundamental power of the earth fire flame.

There is no particularly complicated reason why the reason why the Heavenly Flowing Fire was chosen instead of the Yin Luo Ghost Fire, and it was not to use two fires to blend together as it did in the first creation. After all, the current "Lu Xin" has completely comprehended the true source power of the flame, and has completely stepped on such a realm, so now for him, there is no difference between the Heavenly Flowing Fire and the Yin Luo Ghost Fire, both are just flames of the same origin, and they can also provide the necessary flame power for the strengthening of the Earth Fire.

With a gesture of his hand, a pile of sand flew from behind "Lu Xin" and was caught in his left hand. This sand is called Qianzhang Chen, and it is the material that "Lu Xin" asked for the most in this time, and it originates from the depths of at least a thousand zhang under the island of the Demon Cultivation Sea.

Qianzhangchen is such a thing, "Lu Xin" didn't know about its existence until he came to hell. This kind of thing is actually very ordinary, because it is not rare, but wherever it goes to a thousand feet underground or even deeper, it is generally easy to find, and there are many of them. Moreover, this kind of thing can neither be used in medicine nor used by craftsmen to forge it, so there are very few places where it can work.

But there is some truth to saying that this kind of thing is not ordinary. Because after all, it is not possible to reach the ground under the ground, and to obtain this thousand zhang of dust, even if it is a monk in the realm of "Lu Xin", it will take a lot of effort. Moreover, the earth attribute of this thing is extremely strong, as if it is the essence of the soil in hell. When it comes to the nature of earth, there are few things in hell that can be compared.

"Here comes the fire!" With a flick of his fingers, the raging flame of the sky separated into a small group, and soon came to the right hand of "Lu Xin".

Looking at the small ball of out-of-the-sky flames above his right hand, "Lu Xin" quickly and decisively pressed all the thousands of zhang dust that he was holding in his left hand into the out-of-the-sky fire. The sound of "crackling" sounded, accompanied by the slight movement of blood-red flames, which was an inevitable phenomenon when two completely different things came into contact with each other.

Didn't care about this phenomenon at all, "Lu Xin"'s gaze quickly condensed on the out-of-the-sky fire, and the spiritual power cautiously surged out, controlling the flame on his right hand, and shouted in his mouth: "Refine!"

As soon as he spoke, the fire outside the sky began to beat even more violently as if it were spiritual, and the thousands of feet of dust wrapped in it were quickly burned into a pile of ashes. It's just that this pile of ashes did not fall under the control of "Lu Xin's" spiritual power, but still floated in the flames.

As Lu Xin's spiritual power continued to strengthen, the ashes began to slowly transform into liquid, and after liquid, they slowly became gas. This kung fu is quite similar to that of Wei Bing when he only controlled fire refining materials with his hands, which is also the best proof that "Lu Xin" as a sword casting master, fire control and refining attainments have been perfected.

When Qianzhang dust completely turned into gas, it was still under the control of "Lu Xin's" spiritual power, and it was still tightly wrapped in the flowing fire outside the sky. Doing this, "Lu Xin" took a few deep breaths of air, and he knew that he had now completed the first step of the first material.

There was silence for a moment, but Lu Xin's right hand was still raised, but his eyes were slowly closed. However, the moment his eyes closed, a sharp divine consciousness rushed out of his consciousness threshold and surged into the heavenly flames in his right hand.

"Melt!" A word came out of his mouth again, and the spiritual power of "Lu Xin" still controlled the blood-red flames above his right hand and the thousands of feet of dust gas within the flames. However, this time, what can be found is that there is an extra feeling in the manipulation spiritual power of "Lu Xin", and this feeling is called "delicate".

The current "Lu Xin", what he is doing is to let the heavenly fire in his hand fuse with thousands of feet of dust gas. And once he successfully fused, the Extraterrestrial Flowing Fire in his hand would no longer be the Extraterrestrial Flowing Fire, but the Extraterrestrial Flowing Fire with extremely strong earth attributes. At that time, as long as he erased the original attribute of the Outer Heaven Flowing Fire, the flame in his hand would be a flame that should not have existed in the Three Realms, but an artificial flame rich in extremely strong earth attributes.

This kind of artificial flame is naturally very different from the earth fire, but this is only the first step in the creation of "Lu Xin". As long as he continues to succeed step by step, the flames he creates will have more and more chaotic attributes, and they will become closer and closer to the earth fire.

Now "Lu Xin" doesn't use his eyes to observe, but uses his divine sense instead, and the spiritual power in his hand is extremely finely controlled, because he knows that it is not easy to fuse other things with flames at this step, if there is a little bit of improper control, if there is a mess, then all his previous efforts will be in vain. And more importantly, he doesn't have any more dust now.

With this closing of the eyes, a moment of time has passed. A moment later, when "Lu Xin" opened his eyes again, the original blood-colored flame on his right hand had turned the color of earthy yellow, and it looked like it had a somewhat similar taste to the real earth fire.

"Lu Xin" knew that this was the result of the Heavenly Flowing Fire taking off its original attributes and integrating into Qianzhang Chen. Now he has succeeded in the two steps of "refining" and "melting", and the next thing he wants to do is "group"!
