Lu Fang took out the white jade skull palm and put it on his chest to wait for the demon heart to absorb it, and after a quarter of an hour, when the white jade skull palm, the supreme treasure, turned into powder, it breathed a long sigh of satisfaction with satisfaction.

After waiting for a while, he found that the demon heart had been silent, and he couldn't help but urge in his heart: "Have you forgotten something?" ”

Demon Heart said in a deep voice: "Of course I haven't forgotten, don't be in such a hurry first, it is not a simple matter to directly teach you the secret method of fire, I need to make some preparations." ”

With its current strength, the secret method of fire could indeed be taught to him.

It's just that after absorbing the Treasure White Jade Skull Palm, it wanted to perceive another existence in Lu Fang's body at the cost of consuming a large amount of cultivation origin, the guy who could erase it or prevent it from absorbing his cultivation origin.

Know yourself and know your opponent to win all battles!

After hearing that Lu Fang could erase himself at the cost of fifty years of life, the demon thought for a long time, it must be impossible to do it with his ability alone.

So before it, there was another being in his body.

In any case, it must figure out whether this existence has the strength to erase itself.

If it could, it was willing to lose both at the cost of burning most of its cultivation origin, and the unknown existence, because it couldn't imagine how slow its cultivation speed would be if it had not been able to absorb Lu Fang's cultivation source.

Moment!

At the cost of burning a part of the source of cultivation, the Demon Heart has increased its already terrifying perception in a short period of time, and methods like this to kill eight hundred enemies and self-damage one thousand are generally very effective.

However, it was unable to perceive another existence in Lu Fang's body.

No way!

Could it be that I was wrong? There is no unknown existence at all, it's just that Lu Fang has special extraordinary powers?

However, the strength of extraordinary strength is generally equal to my own realm, and even if it is exceeded, it will not be exceeded.

If it was based on the current strength of Lu Fang, even if he had special extraordinary power, he should not be able to prevent it from absorbing the cultivation origin and erasing it, even at the cost of fifty years of life.

However, I didn't perceive anything else.

What the hell is going on?

Could it be that the unknown existence is too strong, so I can't perceive its existence.

The Demon Heart has already come this far, it will definitely not give up easily, thinking of this possibility, it does not hesitate without any hesitation, burning more cultivation origin, no matter what, it must see that unknown existence this time.

At this moment, its perception has reached a state of extreme terror.

In its perception, it seems that everything in the entire heaven and earth is frozen, but what makes it a little strange is that it still does not perceive any other unknown existence.

Is it true that Lu Fang has special extraordinary powers?

As soon as the Demon Heart thought of this, it was suddenly surprised to find that Lu Fang, who was supposed to be motionless in its super-perceptual state, had become normal.

Lu Fang was normal, but everything around him was still in the same freeze.

This sense of disobedience makes the demon heart wonder, shouldn't it be like this, why is it like this?

Don't wait for it to think about it.

Lu Fang's frowning brows slowly stretched, and he muttered, "Demon Heart, are you perceiving that unknown existence?" Looks like you're curious about it? Just want to see it? ”

With his strength, he naturally won't find the difference.

However, the demon heart cultivated the origin with burning and wanted to perceive the existence of the ink pen book realm, but the realm spirit noticed it and informed him.

Demon Heart: "Now that you know, it's okay to meet each other." ”

Lu Fang was silent, he thought for a moment, and said, "Yes, since you meet, then let you meet." ”

Almost as soon as the words fell.

The demon heart's eyes were dark, and when he came back to his senses, he had already appeared in the ink pen book realm, but the difference was that the current ink pen book realm was full of ink and ink, and all kinds of spiritual books were gone, only a huge pen stood in the heaven and earth.

"This is the unknown being?"

The Demon Heart was a little shocked.

Lu Fang glanced at the heart the size of his head next to him, this was the first time he had seen the demon heart so clearly, it turned out that its body was like this.

Without waiting for him to answer, the giant pen in mid-air waved his pen and wrote a line of words: "You don't have to be curious about me, as long as it is not requested by the host Lu Fang, I will not erase you." ”

The Demon Heart didn't say anything, but used its extraterrestrial perception to perceive the realm spirit, and it wanted to make sure that the other party was so powerful that it could really erase it.

But its idea was frustrated, and it couldn't perceive the realm spirit at all.

The gap between the two sides is too huge.

Even if it had expected it before, it didn't know until this moment how strong this unknown being was.

With another wave of the pen, a rippling aura like water waves spread to the demon heart, and in an instant, the heart the size of a head shrank little by little, and finally became the size of a fist.

"This is punishment for you snooping on me."

The spirit of the realm wrote this sentence.

In the blink of an eye, Lu Fang and Demon Heart came out of the ink pen book realm at the same time.

"Are you alright?"

Lu Fang asked the demon heart in his heart.

He didn't expect that the realm spirit would do something to the demon heart, but he didn't care, but he was a little worried that it wouldn't be able to teach him the secret method of fire now.

Demon Heart's voice was a little weak, and he said, "I taught you the secret method of fire, and you need to sleep for a while. ”

As soon as the words fell.

A memory appeared in Lu Fang's mind, this was a technique about fire control, this memory appeared and disappeared over and over again, and in just a quarter of an hour, he had already practiced it in his mind many times.

"Are you the secret method of fire control?"

As soon as Lu Fang stretched out his hand, the fire in the stove was pulled into his palm, and with such a high flame temperature, he just felt warm.

With a thought, a large mass of earth fire condensed into a little blue light.

What made him feel miraculous was that this light was hotter than the previous ground fire.

After waiting for a long time and not seeing the Demon Heart respond, Lu Fang estimated that it had just used a certain method to perceive the realm spirit of the Ink Pen Book Realm, and it must have consumed a lot of cultivation origin, plus it was finally punished by the realm spirit, it should have really fallen asleep now.

In fact, he didn't want to do this, maybe he would soon encounter an ancient alien race, and at this time, the demon heart was sleeping, which would definitely be bad for him.

But that's already the case, and he can't help it.

Without the reminder of the Demon Heart, Lu Fang carefully used the earth fire controlled to start melting the solid stone, and sure enough, as the Demon Heart said, the temperature of the earth fire controlled by the secret method of fire was just enough to melt the solid stone.

Melt into molten iron and pour it into the sword embryo.

In addition to the difficulty of melting the solid stone, the other processes are quite simple, he has also communicated with the demon heart before, the solid stone is naturally lethal to punishment, and only the simplest sword embryo is needed.
