Outside Biyun Mountain, many mountains have collapsed, and patches of verdant forests no longer exist, and the smoke of gunpowder is billowing out, and the murderous aura is running around.

For mortals, this is simply a devastating disaster, and what is even more incredible is that not only the mountains and forests have been destroyed, but the surrounding space has been distorted and deformed, and black space-time cracks have appeared, and in the dim scene, it looks like the end of the world is coming.

"Buzz!"

At this time, a powerful slashing sword intent continued to shatter the square space, causing a roar!

Even Biyun Mountain trembled because of this, and the internal defensive array became unstable, which made several elders of Biyun Mountain speechless, and hurriedly took measures to close the mountain, so as not to affect the mountain gate.

"Slash!"

The roar of the stars in the sky was so angry that it didn't disperse for a long time, and the place where the sound wave passed was devastated and decayed, and there was nothing left to remain, and it approached where Wu Heng was.

Wu Heng's pupils contracted violently, and he faintly felt that the "slash" was mixed with the power of the true extreme path, and it had surpassed the Ascending Immortal Realm in a certain field, which completely subverted common sense, it should not be a means that a Ascending Immortal Three Realms monk could have, it was estimated that even the existence of the Ascending Immortal Peak would not be able to reach such a majestic aura with all his strength.

It's hard to imagine what kind of opportunity Tianzhong Xingchen got in the deserted city, and it actually made him comprehend this earth-shattering fourth slash!

"Something is wrong, why is the breath of that slash still rising, and the powerful has already crossed the line. "Many of the sect leaders changed color, and if it was a surprise to see the initial form of the Heaven-shattering Fourth Slash before, now they are all starting to feel a little frightened.

"What's going on?"

Biyun Mountain began to shake violently, causing many guests to panic, you must know that at this time, there are several elders who are controlling the defensive array, but even so, the mountain gate is still a little unstable.

Why would there be such a level of aura fluctuations on a monk who had ascended to the Three Realms of Immortals?

"Wangwang!" the big yellow dog jumped in fright, its hair stood on end like a hedgehog, and it shouted, "Oh no, Wuheng is in danger!"

Xuehua, Allure Snow, Liu Cheng and others also found something wrong. At the moment, it is not a normal competition at all, and it can be said that Tianzhong Xingchen is suspected of cheating.

In the face of the earth-shattering fourth slash of the stars, Wu Heng's chances of winning are slim, but at least he still has the ability to resist!

But now there is a great secret in the slash of the Heavenly Vertical Stars, which has shaken the defensive array of Biyun Mountain, which shows that it is not just as simple as the fourth slash, and some immortal masters do not think that they can survive that blow.

"Stop!" Suddenly, a roar turned into rolling thunder and resounded in the sky!

It was the immortal lord of Tianhe Star who shouted, and then he jumped up and disappeared into a black light on his seat.

At the same time, the old immortal lord of Biyun Mountain, the old man of the camel turtle and others all set off, wanting to save Wu Heng's life. They are all speculated by the world to be beyond the existence of ascending immortals, a body of supernatural creation, but in this life, the kind of immortal power fluctuations emanating from their bodies when they leave is like a heavenly power suppressing the world!

"It's too late. On the other side, the middle-aged man sitting in the special seat shook his head gloomily, he knew very well that he couldn't save Wu Heng, and he also knew very well that if he couldn't save Wu Heng, then who else could save Wu Heng?

On the main battlefield, Tianzhong Xingchen didn't pay attention to the few strong men's breaths that pressed over, he was already carried away by hatred, and continued to kill Wu Heng.

At this time, the stars of the sky were simple and unpretentious, and the bright fairy light on his body had dissipated, but his fierce sword intent was incomparable, and he comprehended the return to the basics and walked into a kind of extreme path!

"I have accumulated this sword intent for twenty years, I didn't use it when I practiced nine deaths in the boundless starry sky, I originally planned to keep it to kill the strongest opponent on the path of future certification, it stands to reason that you are not qualified to let me do this, but you must die today!"

In an instant, Wu Heng's mind was blank, and he didn't expect the fourth slash of Tianzong Xingchen at all, and he didn't expect that Tianzong Xingchen had a secret technique of accumulating sword intent, and he had accumulated over time to stay step by step to today!

The sword intent that has been accumulated for more than 20 years by a genius of heaven and soul has exploded at this time, and it is a powerful force that I dare not imagine.

It's no wonder that even a few elders of Biyun Mountain couldn't hold the mountain gate formation, no wonder so many sect leaders were terrified. Tianzhong Xingchen is completely fighting for his life, and finally the hole cards are used!!

As the stars approached, Wu Heng's oppressive force became greater and greater, and his body could not support it at all, and the blood in his body was tumbling.

"Poof"

Wu Heng coughed up blood, his face turned pale, and the stars were still dozens of miles away!

The fourth slash did not fall on Wu Heng, this was just a prelude to the fourth slash, forcing his blood and qi to flow backwards.

He felt the breath of death, and knew very well that what he would do next would be the result of nine deaths.

"Vertical!"

Wu Heng screamed in pain, his bones crackled, and his shoulders seemed to be pressed by a sacred mountain, and it was difficult to move!

"Detachment!"

Wu Heng shouted again, and the four big words "vertical and horizontal" and "detachment" appeared in his mind.

The way of vertical and horizontal is what he observes in the sea of suffering, and the way of detachment is that he comprehends according to the font copied by the snow in the city. It stands to reason that it is difficult for him to appreciate the essence of the word "detachment" copied from the snow in the city, but in recent times, Wu Heng has integrated the word "detachment" with the mystery of "the road is one", and he can also achieve a good effect, which is almost not weaker than the "vertical and horizontal" he comprehends.

Wu Heng had used the Immortal Demon Dao twice before, the first time was in the deserted city, and the second time was when he killed Xuanyuan Ge.

The first time it was used was to integrate one of the seven small parts of the Pangu Immortal Sutra Secret Classics with "vertical and horizontal", that is, the Great Dao was unified and mysterious, and it was very powerful, and it swept all the same generation in the deserted city at that time.

The second time belongs to the enhanced version, integrating the "detachment" of the snow copy of the city, but after all, I couldn't see the real "detachment" stele with my own eyes, and I could only use the effect of the fairy and demon Dao fur.

This time it was completely different, Wu Heng's Immortal Demon Dao had made a qualitative leap again!

Gradually, Wu Heng flowed out of an indescribable artistic conception, with thousands of Tao implications, supreme!

He took a deep breath and threw himself into the mysteries of the Immortal Demon Dao, entering a strange space, a new world, surrounded by emptiness and soft light.

"Sure enough, the Immortal Demon Dao is unparalleled in the world, and it can resist the suppression of the sword intent of the Heavenly Vertical Stars!" Wu Heng was overjoyed, and found a ray of light from despair. In addition, there is a purple immortal light blooming in the center of his eyebrows, if he just uses the Immortal Demon Dao, I am afraid that it will not be enough to resist, and the power of the immortal must be used.

"Do you think you're the only one who has an immortal age?" The eyebrows of the stars in the sky also bloomed with immortal rays, and the immortal light illuminated the four directions!
