Mu Yi looked at the willow demon who was still struggling, and thought of his powerlessness in the face of the willow demon at the beginning, and in a blink of an eye, the situation was reversed, even Mu Yi did not expect that this day would come so quickly, and the law of the weak is the eternal law of the underworld.

Mu Yi stepped out in a few steps, looked at the willow demon condescendingly, and said slowly: "Surrender to me, you may have a day of detachment." ”

Hearing Mu Yi's words, the willow demon struggled even more violently, and at the same time, an illusory face emerged, it was the appearance of an old man, staring at Mu Yi with a pair of empty eyes.

"Still unwilling to surrender?" Mu Yi frowned slightly, "Since this is the case, then wipe your sanity away, although the effect will be a little worse, but such a heaven and earth spirit root is also rare." ”

Saying that, Mu Yi slowly raised his hand, ready to completely erase the willow demon's sanity, with his current realm, even if the willow demon is the eighth heaven, there is still no power to resist, as his palm fell, the illusory face began to struggle violently, and finally, just when Mu Yi's hand was about to be submerged in it, a jerky voice sounded.

"Please spare your life."

At the same time, the willow demon also retracted his aura, his body shrank rapidly, and he became ordinary again.

"Open your heart, merge with it, and sit in my world from now on." As Mu Yi spoke, an illusory world suddenly appeared behind him, making the willow demon tremble violently, and finally obediently let the rune submerge into his body.

Subsequently, a breath that had been accumulated for an unknown number of years burst out, if it was really about the foundation, then the willow demon had actually reached the peak of the Eight Heavens early, but it was too difficult for a spiritual root like it to break through.

It's not that no one has ever fought its idea before, but once the Willow Demon is desperate, it will be difficult for the Nine Heavens to surrender it intact, and it will even bring a lot of trouble, which is why the Willow Demon has always existed here.

Originally, if the willow demon wanted to break through, it would take at least a few hundred years, but now, because of a sub-rune, this situation has completely changed, and what the willow demon lacked was the perception of the realm, but now, under the improvement of the realm of Mu Yi's quasi-emperor level, coupled with that little bit of origin, it suddenly triggered a qualitative change.

In the body of the willow demon, the huge power was ignited, and began to change, lifting its body, and the willow branches and roots that were broken before not only recovered quickly, but also became bigger one by one, but this kind of growth was not the kind that the willow demon was desperate for before, but a kind of growth.

The entire valley trembled violently, and within hundreds of miles around, a thick crisis hung over the heads of all living beings, as if the sky was about to fall.

As for the above the willow demon, there are even black clouds rolling, and there are silver snakes swimming in it, and it seems that the willow demon has to bear the punishment of heaven if it breaks through.

"How so?" Mu Yi was a little puzzled, at least he had never encountered such a situation, could it be that the grass and wood spirit creatures broke through to the Nine Heavens and suffered a thunder tribulation? But why are there no living beings? And although Mu Yi could also feel the suppression of heaven and earth before, it was nothing more.

However, at this time, the willow demon resolutely began to break through towards the Nine Heavens, and his aura became higher and higher.

Finally!

"Boom!"

As the heavenly thunder fell, the heavens and the earth suddenly lit up, even if they were separated by a distance, Mu Yi could still feel the destructive power contained in the heavenly thunder, and it fell directly on the willow demon.

"Ahh

Faintly, Mu Yi heard the screams from the willow demon, and countless willow branches turned into ashes in that instant, and half of the rest were scorched black.

But Mu Yi could feel that in the underground, it seemed that a more surging vitality burst out, and then the willow demon soared again, and countless willow branches shone brightly, stretching unscrupulously, as if they were provoking the heavenly thunder overhead.

"Boom!"

Another thick thunder fell, this time, the willow demon was more seriously injured, at least half of it was directly turned into ashes, that kind of power, even Mu Yi couldn't help but reveal a little dignified, he faintly felt that this willow demon was probably even more extraordinary than he imagined, and more mysterious.

But now, all he needs is to wait, as for that rune, even if the willow demon is completely dead, it will be broken at best, as long as he takes back the salary lamp and recuperates for a period of time, it will be restored.

But Mu Yi hopes that the willow demon can succeed, so that he may also know the secret.

Although it has experienced two heavenly thunders, in Mu Yi's induction, the true core of the willow demon has not been damaged, on the contrary, it seems to have thrown away its heavy burden and began to transform more rapidly, and once it succeeds, it will also reach the Nine Heavens.

Don't look at the gap between only one heaven, but in fact, the eight heavens are already the end of many lives, and if you go up, you have to transcend yourself, and right now, the willow demon is detached.

At the same time, the third heavenly thunder has also been conceived, and it fell with a bang, and this heavenly thunder is much stronger than the previous two combined, just one blow, it completely wiped out all the parts on the ground of the willow demon, leaving only a deep pit.

"What a powerful force to destroy." Mu Yi's body shook and appeared on the edge of the pit, still thinking of the last thunder in his mind, the kind of indestructible, the power of destruction, which reminded him of the punch in his memory, which was also indestructible and full of destruction.

Gradually, there was a trace of thunder around Mu Yi's body, and some of the remaining thunder power in the original pit was all submerged into Mu Yi's body, and Mu Yi also came to open a posture, slowly clenched his fists, and suddenly, a terrifying, with a breath of destruction appeared on Mu Yi's body.

Originally, Mu Yi's nine-turn golden body duel fused with the true intent of thunder, and at this moment, feeling the power of the thunder, he was faintly touched, and his fist intent slowly changed, but I don't know why, Mu Yi always felt that there was something wrong with this punch, and something was missing, but he couldn't hit it for a long time.

Suddenly, in that deep pit, a burst of vitality burst forth, and at the same time, it also plucked the string in Mu Yi's heart, and finally made him understand what was missing in his fist intent.

Although thunder is destruction, it also has vitality in destruction, so that it can be endless.

The instant realization made Mu Yi's fist intent suddenly have a trace of endless meaning, and it was perfectly integrated.

"Broken!"

Mu Yi's punch, which had been gathering momentum for a long time, finally struck, and it only swept over a distance of hundreds of zhang in an instant, until it was several miles away, before it crashed into the hill, and in an instant, the hill turned into powder, but the punch also dissipated.

"Boom."

At this moment, the pit began to shake violently, and a touch of green rose into the sky.
