The huge Heart of the Emperor Domain suddenly vibrated and then shrunk continuously, turning into an old human form.

With a kind face, he looked at Yang Yi who was pale.

"Xiaoyou is seriously injured, let the old man help you!" The heart of the Emperor Domain pointed with one hand, and the endless heaven and earth vitality wrapped Yang Yi.

Although the Heaven and Earth Yuan Qi is fierce, it is very gentle, constantly wandering in Yang Yi's meridians, whether it is internal or external, it has begun to heal gradually under this warm Heaven and Earth Yuan Qi.

"Hey, Xiaoyou's power is very peculiar, although it is born from the Heaven and Earth Vitality, but it is different from the Heaven and Earth Vitality, even the old man has never seen it before!" A strange light appeared in the eyes of the Emperor's Heart.

Yang Yi breathed a long sigh of relief, and stood in the sky, the serious injury just now had already recovered.

The void fluctuated, and the white-haired and white-bearded guardian of the Emperor Domain walked out.

When the Heart of the Emperor Domain saw the Guardian of the Emperor Domain appear, it did not have any surprised expression, but seemed to be very familiar.

"Old friend, you're here!"

The guardian of the Emperor Domain looked at the core location of the Emperor Domain, which had been destroyed by madness, and sighed softly.

"Old friend, has your seal been opened?"

The Heart of the Emperor Domain nodded: "Yes, the Twin Towers of Gods and Demons have been killed by this little friend! Even the old man was very surprised, this little friend's strength is very strange, is he the legendary Mandate of Heaven? Only the Mandate of Heaven can have the power to kill gods and demons!"

The guardian of the Imperial Domain smiled slightly: "Yes, when the old man noticed the power of this little friend, he was also surprised, this kind of power is also unprecedented, so the old man showed up and let the little friend inherit this destiny!"

Yang Yi moved his body for a moment, and said with a wry smile: "I said two old men, as soon as you move your mouth, it's simple, but I almost died!"

The heart of the emperor domain said: "Xiaoyou also saw that although the old man is the heart of the emperor's domain, he was also completely imprisoned here by the seal set by the gods and demons, and now the old man has run out of oil and dried up, and in less than 10,000 years, I am afraid that he will be purified by the gods and demons, and then swallowed by them, and then the emperor must be devastated!"

Regarding this, Yang Yizhi nodded: "You're right, the gods and demons are extremely ambitious, and they are a very formidable enemy!"

The Imperial Domain guarded and smiled slightly: "But Xiaoyou has the strength to kill the gods and demons, and this is the responsibility of inheriting the Imperial Domain, and now it will fall on Xiaoyou!"

Yang Yi shrugged: "Yes, anyway, my family is above this Emperor Domain!"

The Guardian of the Imperial Domain and the Heart of the Imperial Domain glanced at each other and nodded at the same time.

"Xiaoyou, the old man's destiny has passed, I will pour all the true elements into the heart of the Emperor Domain in a while, and then Xiaoyou can devour the Heart of the Emperor Domain and truly become the master of the Emperor Domain, the rest of the matter will be please!"

There was a hint of determination in the eyes of the guardian of the Emperor Domain, and then he put his hands behind his back, and his body emitted starlight, and the endless heaven and earth vitality rushed into the sky, and then poured into the body of the Heart of the Emperor Domain.

The human form of the Heart of the Emperor slowly vanished, leaving behind only a wonderful object.

"Little friend, as long as you devour this heart of the Emperor Domain, you will be the master of the Emperor Domain, hehe......"

The figures of the Guardian of the Emperor Domain and the Heart of the Emperor Domain disappeared at the same time, and the voices continued to echo until they finally disappeared.

Yang Yi stood in the void, looking at the Heart of the Emperor Domain, which represented the Great Dao of the Emperor Domain in front of him, and did not choose to devour.

Devouring a heavenly and earthly treasure is a very normal behavior for a martial artist, but Yang Yi is not a simple martial artist, he is a real cultivator in his bones.

Cultivators have a lot of means to deal with a treasure of heaven and earth, devouring is the lowest one, Yang Yi has already had an idea when he saw the heart of the emperor domain, he wants to refine the entire emperor domain into a magic weapon, integrate it into his own sea of knowledge, and use the power of the heart of the emperor domain to completely condense his sea of knowledge into an inner world, from then on, the entire emperor domain can be large or small, and even use the power of the emperor domain to suppress the enemy.

Yang Yi has great ambitions, since he knows that the Tian Yuan World has eight domains, then integrate the Tian Yuan Great World, completely integrate the eight domains, and refine them into a true innate magic weapon.

"Well, let's do it......!

Now that there is a vague connection between Yang Yi and the Heart of the Emperor Domain, he can also borrow all the Heaven and Earth Yuan Qi above the Emperor Domain.

Standing in the sky, sitting cross-legged, Yang Yi's hands continued to condense the magic technique, and constantly injected into the heart of the Emperor Domain, because the Heart of the Emperor Domain has returned to its original form, and there is no longer any ability to resist, so Yang Yi's magic trick is also entered into the Heart of the Emperor Domain without resistance.

One day...... Two days...... One month...... Two months......

For a hundred days, Yang Yi had never felt so tired, this was also the greatest method of assimilation that he had never used, the heart of the Emperor Domain had been completely integrated with him, and he now had a feeling that one step out could run through the entire Emperor Domain, and for any item in the Emperor Domain, he could think of life and death.

"Hahaha......" Yang Yi laughed, stood up, his body shook, and the heart of the Emperor Domain was completely integrated into his inner world.

For a full hundred days, Yang Yi's sea of knowledge is like Pangu opening the world, the light one rises, the heavy one lands, the exhalation becomes the wind, and the tears become rain.

It's just that Yang Yi's inner world is dead silent, and there is no life, when the heart of the emperor appears, the entire inner world begins to rejuvenate, a little green appears, trees and flowers, endless vitality begins to appear, and Yang Yi's whole temperament has also begun to be sublimated, and the infant continues to grow, turning into chaos and infinite fixed on Yang Yi's sea of knowledge.

"Hehe, it's a success!" Yang Yi put his hands behind his back, took a step lightly, and countless stars appeared around his body in the form of disillusionment, and then, his aura continued to rise, making the entire world shake for it, which was the precursor to the advanced Sumeru realm, and Yang Yi was not an ordinary Sumeru realm, and at the same time, he had advanced to the cave void period.

The fusion of the heart of the Emperor Domain made Yang Yi begin to comprehend the wonder of the Heaven and Earth Cave Void Dao, and as soon as his eyes opened, he saw countless red lines in the Heavenly Dao, which were constantly entwined and distorted.

"Is this cause and effect?" Yang Yi muttered to himself, his voice as if it had penetrated the void and kept reverberating.

Then, he saw countless red threads connecting to him from the void.

"Hehe, so much cause and effect, Heavenly Dao! I don't want to be your puppet!" Yang Yi shook his head, although he can see through the void now, the strength of the Void Period is not enough to cut off the cause and effect.

"Well, now, let's integrate this Emperor Domain!"
