Hearing Yang Fan's words, the Yan Demon suddenly screamed like a cat whose tail had been stepped on, "Don't you think, kid, don't daydream, even if you don't die, this seat will not give you the Heart of Earth Rock."

The roar of the fire demon shook the heavens and the earth, and a pair of eyes stared at Yang Fan deadly, full of coldness.

The heart of this earth rock is a supreme divine treasure, and it is recorded in the Kyushu Mountains and Rivers Chronicles that the heart of the earth rock is a supreme divine treasure bred in the underground world, which is somewhat similar to the heart of the divine power of the heavenly sea bred in the ocean.

The Heart of Earth Rock is a metallic treasure that can only be found in the underground where fire demons can be born.

Since this flame abyss gave birth to the Fire Demon, it must have the existence of the Heart of the Earth Rock.

Yang Fan's heart was naturally hot, if he could get the heart of the earth rock, he could directly devour it, and even comprehend the Golden Dao.

In this way, it is only one step away from the integration of the five elements and breaking through the realm of martial arts.

However, it is obvious that the value of the Heart of Earth Rock is too great, it is one of the most precious divine treasures in the gold system, and the Fire Demon will not hand it over so easily.

Even because the Earth Rock Heart Flame Demon dared to fall out with Yang Fan, he directly killed Yang Fan.

However, Yang Fan knows that the treasure of the Heart of the Earth Rock is hard to find, only this place has it, if he misses it, the golden supernatural power does not know when he will be able to comprehend, and he does not know when he will be able to enter the realm of martial arts.

So he had to seize this once-in-a-lifetime opportunity.

Yang Fan said, "Flame Demon, I know that the heart of this earth rock is a heavy treasure, and it is extremely important to you, but we can make an exchange."

"I won't change anything for this seat, even if it's the legendary immortal elixir this seat, I won't change it" The fire demon sneered, "The heart of the earth rock is the foundation of the rise of this seat, and no one can take it away"

"Flame Demon, you have been bred in this flame abyss for more than 100,000 years, the ancient one is unimaginable, have you ever thought of going out one day?" Yang Fan asked.

"Do you have a way?" Yan Demon looked at Yang Fan coldly, licked his hideous mouth, and said, "If it devours your Red Flame Demon Fire, this seat can go out"

There was a cold glint in his eyes, as if he had thought of something, and then a look of fear flashed as he shook his hideous head, apparently trying to throw this tempting but deadly threat out of his mind.

But he was not reconciled, and the flame demon said, "If your red flame demon fire is exchanged with this seat, this seat will promise you"

Yang Fan said with a dark face, "Although the Heart of Earth Rock is precious, it is still much worse than Tianhuo, your idea is good."

"Hmph, then there's no need to talk about it, before this seat changes its mind to kill you, it's best to quickly take the initiative to disappear here" The Fire Demon smiled coldly.

Yang Fan said, "Why are you in such a hurry to let me go?

"Oh, what way?" the fire demon's eyes flashed.

"I am the descendant of the Ancestral Saint, and I will definitely reign in the heavens and all worlds in the future, I know that you can't get out of this flame abyss now because you can't form your own fire demon heart, so you must rely on this flame abyss to survive, slowly refine the heart of the earth rock, and let the heart of the earth rock gradually transform into the heart of the fire demon"

Yang Fan said slowly, as if he had mastered everything, and his demeanor was extraordinary, "However, even if you condense for 100,000 years, you may not be able to successfully transform, unless one day you fuse the Heavenly Fire, maybe the success rate will increase a little."

"That's right, you know very well, but what can you do to help this seat?" the Flame Demon looked at Yang Fan, with a hint of expectation in his flaming eyes.

"There is naturally a way, as long as I cultivate to the realm of the Great Emperor, you and I can work together to refine the heart of the earth and rock together, and help you turn into the heart of the fire demon, and then you can leave this flame abyss," Yang Fan said.

"The realm of the Great Emperor? haha, funny, really funny, you are really ridiculous~~~~~ do you think the realm of the Great Emperor is so easy to reach? This seat has been trapped at the peak of the Emperor Realm for 50,000 years, but it has been unable to break through the Great Emperor Realm for a long time, who do you think you are? If you want to break through the Great Emperor Realm, you can break through?"

Yan Demon sneered, "Your empty gloves and white wolf methods are really clumsy, this seat advises you to take back that little thought"

Yang Fan shook his head and said, "It may be unimaginably difficult for others to reach the realm of the Great Emperor, since I, Yang Fan, am the heir of the ancestral saint, it is natural to achieve the realm of the Great Emperor."

Hearing Yang Fan's words, the Yan Demon was silent for a while, as if he was thinking, and seemed to be weighing the pros and cons.

The facts are indeed very similar to what Yang Fan said, is it not easy for the ancestors to reach the realm of the Great Emperor?

Yang Fan continued, "Half a year ago, I was still a Martial Apprentice Realm Triple Heaven Cultivator, a low-level cultivator, sitting in a well and watching the sky, and then I got the Ancestral Saint Inheritance by chance, and in just half a year, my cultivation has reached the peak of the Martial Master Realm, and my strength has reached 9.99 million stones, which can almost sweep the powerhouses below the Martial Artist Realm, do you think I still can't break through the Great Emperor Realm?"

Yang Fan's cultivation experience was indeed too shocking, even an old monster like the Flame Demon was shocked.

In Yang Fan's realm, he thought about it for a while, and he estimated that he would be slapped to death by Yang Fan.

That's the terrible thing about the ancestors.

In fact, how does Yang Fan know what the ancestral saint is, he has never heard of this title, he has only heard of the human race hundred saints, I don't know if it has anything to do with the so-called ancestral saint?

However, since the Yan Demon has identified his identity as the heir of the Ancestral Saint, Yang Fan doesn't mind pulling the tiger skin, no matter what, he will get the Heart of Earth Rock first.

The fire demon's eyes flickered violently, as if he was thinking, as if he was weighing, as if he was struggling.

He bit it and said, "Okay, this seat will believe you once, to be precise, it is to believe in the ancestral saint once, this seat believes that the ancestral saint's vision will not choose the wrong successor, but this seat can't casually give you the heart of the earth rock, this is related to the foundation of this seat, if you get the heart of the earth rock and then break the appointment with this seat, won't you lose your wife and lose your soldiers?"

Yang Fan nodded, and said, "Okay, I will make an oath to let you rest assured in your heart, I, Yang Fan, swear here, after the Yan Demon hands over the Heart of the Earth Rock to me, he will definitely return to this Heavenly Demon Sanctuary to rescue the Yan Demon from the sea of suffering, if he violates this oath, he will definitely suffer a great injury in the future."

The Great Dao Wound, which is the so-called "Dao Wound", is the scar left by the Heavenly Dao in the cultivator's body, which is almost incurable, unless it is an immortal elixir, but the immortal elixir is difficult to find, and the Holy Mother of Da Luo who is as powerful as Da Luo almost died under the Great Dao Injury.

This kind of oath is almost one of the heaviest vows of a cultivator.

You must know that in this world of cultivators, there is a destiny in the underworld, and many oaths are very effective, so cultivators rarely swear, because breaking the oath will often be rebuffed by the oath.

In the world of Kyushu, there are often lightning and thunder in the clear sky in broad daylight, that is, a cultivator has broken his oath and has been thundered by the sky.

So seeing that Yang Fan made an oath, the Flame Demon was very satisfied.

With a flick of his giant claw, a flame flew in.

In the midst of the flames swirled a fist-sized stone.

The stone was full of golden color, beating violently, like a heart, exuding endless golden energy.

The stone that beats like a heart is the heart of the most precious rock.

Yang Fan was thrilled.

He grasped the Heart of Earth Rock in his hand, and immediately felt a strong and powerful beating sound.

"Heaven Swallowing Divine Skill, Refining with All Strength" Yang Fan directly operated the Heaven Swallowing Divine Skill and refined it in front of the Yan Demon, letting the Yan Demon know that he had definitely obtained the ancestral saint inheritance, which made this terrifying old demon feel fear in his heart.

It didn't take long for the heart of the earth rock to be completely refined by Yang Fan and absorbed into the body, and suddenly, the power of the gold system began to resonate with the rest of the three systems, water, fire, and earth.

Buzzing, the power of the gold system seems to be condensed and formed, and the supreme magic technique will evolve.

Eternal years, but a dream.

The Young Emperor stepped out again and practiced the magic method for Yang Fan.

The flame demon seemed to sense something, his body trembled violently, and he exclaimed, "Ancestor Sheng, come out again, boy, what are you doing?"

He quickly shrank into the depths of the abyss, obviously extremely jealous of the Young Emperor.

Yang Fan didn't pay attention to him at all, and wholeheartedly comprehended the wonderful technique that the Young Emperor practiced for him.

"The Golden Emperor's Ascension to Heaven"

It's a kind of avenue.

Avenue of Gold.

The Golden Emperor Ascension Dao, the pinnacle of the Golden Dao Divine Power, can evolve the Golden Emperor Divine Fist, which resonates with the Fire Emperor Fist, the Water Emperor Fist, and the Earth Emperor Fist evolved by the Emperor Heaven Thick Earth Dao.

The Young Emperor disappeared in a flash, and Yang Fan also opened his eyes, and punched three times in succession, the golden light was brilliant and dazzling, which was the essence of the Golden Dao.

At this moment, Yang Fan, the way of the five elements has been learned by him, four of them.

Although the attack power of these five elements is not very powerful, each of them is the foundation of their own Dao magic powers.

Because the five elements are the foundation, the foundation that supports the universe of heaven and earth.

Without one of the five elements, Yang Fan is only one step away from being able to enter the realm of military generals.
