This tree demon maze is very close. From the surface, there is no flaw at all. If an ordinary spiritual practitioner falls into this place, he will almost die. Even a spirit king will be exhausted to death.

But Yun Yi is different. Not only will he not be afraid or nervous, but he will be extremely excited. With the Yuan Formation Heavenly Book in his hand, there is no large formation in the world that he cannot break.

Moreover, if the formation is too weak, it will not arouse his interest. The maze seems to be flawless, but Yun Yi likes it the more he always likes challenges.

More importantly, constantly challenging difficult formations is of great benefit to Yun Yi, and can continuously increase his attainments in the formation.

At that time, the Jiujiu Guiyi formation in the Jiujiu Asura Sword Formation was broken by him. How could this mere tree demon maze formation be difficult for Yun Yi?

Yun Yi held a sword in one hand and continued to fight against the tree demon, while his other hand continued to form a series of restrictions. At the same time, his soul power spread and rippled in the valley.

The powerful soul power penetrated into the middle of countless tree monsters. As long as the maze was running, Yun Yi could rely on the soul power to cooperate with the Yuan Array Heavenly Book to quickly find the trajectory of the maze operation.

It is not difficult for Yun Yi to rely on the trajectory of the maze to break the formation.

However, to break such a complex maze, it is not enough to proficient in the formation alone. It requires strong strength and continuous supply of spiritual power, and to achieve one's own purpose. After all, this is not simply breaking the formation, but also fighting in the process of breaking the formation. The attack power of those vines is very strong and not so easy to deal with. If there is no continuous spiritual power to support the battle, even if the maze operation track is found, the track of the maze operation has been found.

The traces are still useless. It is difficult to break the formation. Once the spiritual power is insufficient, let alone break the formation, people will die tragically under the attack of these vines.

Fortunately, these problems are not a problem with Yun Yi. This situation is something he often encounters. When he broke the Nine-Nine Asura Sword Formation, it was many times more dangerous than here. It can be said that it is not on the same level at all.

Boom...

There was endless roar in the valley, fire waves were surging, vines were flying all over the sky, like moving snakes. Not to mention being in it, even standing outside, it made people feel numb in the scalp.

This continuous battle lasted for an hour. Yun Yi's eyes were very different. The more he fought, the more he became, the more he was brave, and he was invincible.

In an hour, Yun Yi finally figured out all the movement trajectories of the tree demon maze.

Not only that, Yun Yi also accurately found the location of the Tree Demon King.

"Haha, the tree demon maze, break it for me."

Yun Yi laughed wildly, and his whole body suddenly burst out and rushed towards the position of the Tree Demon King. The Jiuji Sword was swinging in front of him, and the vines were cut off continuously, which was simply unstoppable.

Puff!

Yun Yi's battle sword was as powerful as a bamboo shoot, and he thrust into a big tree that looked inconspicuous.

Ao Wow!

The big tree actually made a shrill scream, and a red blood flowed out of the trunk, dyeing the body of the Jiuji Sword red.

Crazy...

The next moment, there was a clamor, and the vines all over the valley began to disappear quickly, and disappeared completely in the blink of an eye. The originally manic valley suddenly became clear and bright.

Yun Yi's sword not only stabbed the tree demon king, but also pierced the eye of the maze formation, killing two birds with one stone.

"Damn human, how dare you hurt me."

A hoarse voice came from the tree demon king, and a powerful recoil force suddenly tilted out of the tree demon king's body. With the flood of this force, Yun Yi was also bounced back.

However, Yun Yi's strength was strong after all, and he instantly stabilized his body and hung in front of the Tree Demon King.

"It's indeed a tree demon king. Judging from his aura, his cultivation should be at the peak of the first level of demon king."

Black Wind said with a smile.

"With my current strength, it is no problem to kill a tree demon of the first level of spirit king."

Yun Yi smiled and said, not caring about the tree demon king at all, this is his confidence in his own strength.

In Yun Yi's opinion, the most terrifying thing about the Tree Demon King is that kind of maze. If he loses the maze, he is just an ordinary demon king. Yun Yi even killed Lin Qingshan. How powerful is this tree demon king than Lin Qingshan?

What's more, Yun Yi's wood spirit is much more powerful than this tree demon. The supreme wood spirit also has a certain degree of suppression on ordinary wood spirits.

Moreover, his own fire was also unbearable for the Tree Demon King.

"Damn kid, he actually dared to break my formation and seek death."

The tree demon king was furious, and the huge tree body suddenly shook, and branches flew out again, like sharp swords, covering the sky and trying to penetrate everything.

"Hmph! Without the formation, your little trick is simply too weak. Let you see my wood aura."

Yun Yi snorted coldly, his spiritual body transformed, and the powerful wooden spirit body rippled open, and countless spiritual powers also turned into sharp blades and attacked the branches of the tree demon king.

"What? It turns out to be the innate Yi Wood Qi. How could you have such noble wood Qi on your body?"

The tree demon king was shocked, and the huge tree body swayed, which seemed too shocking. As a tree demon, he was a wood spirit, and his perception of the spiritual energy of wood was beyond ordinary people.

But the next moment, the shock of the Tree Demon King turned into excitement: "Hahaha, it's great, the innate Yi Wood Qi, as long as I eat you and absorb your wood Qi, I will be able to completely break away from the tree body and become the real king."

As he said that, a bloody mouth appeared on the tree trunk of the Tree Demon King. The huge tree demon broke away from the original place and rushed towards Yun Yi, as if he wanted to eat Yun Yi directly.

A wood spirit body with the innate Yi Wood Qi is so attractive to the Tree Demon King.

However, Yun Yi is not that delicious. If you want to eat him, you are afraid that your teeth will not be good.

"I won't be with you Moji, Jiuyang Burning Heaven, kill me."

Yun Yi didn't want to waste too much time on the tree demon, so he immediately used the Nine Yang Burning Heaven Technique, and nine fire dragons roared out and instantly entangled the tree demon.

Ahhh…

The next moment, there was an extremely shrill scream. With the addition of the Red Lotus Karma Fire, the Nine Yang Holy Fire Beast was even more powerful than the previous Nine Yang Holy Fire Beast. It was really easy to burn wood.

This is complete suppression, and Yun Yi's own strength is not inferior to the Tree Demon King at all. In addition, he had no reservations and used the Nine Yang Burning Heaven Technique to come up, so how could the Tree Demon King bear it?

"The tree demon king can't withstand the burning of the Nine Yang Heavenly Burning Technique. You can take the opportunity to absorb the essence of his wood spiritual energy and impact the Nine Heavens of the First Line." Hei Feng reminded him.
