The Great Immortal with Boundless Magical Power

The void was as dark as night, and as cold as a bitter winter.

As far as Gao Xian could see, he could only see darkness, and the filthy ghosts wandering in the darkness.

The thick foul air around him was extremely foul, just like the smell of a cesspool where rotten meat had been rotting for dozens of days.

The foul air was extremely sticky, like glue, not only sticking to the flesh, but also sticking to the spirit.

The foul air was fine and sharp, and once it was contaminated, it would continue to penetrate inward.

Gao Xian had such a strong flesh, and his fingers turned black in an instant after being contaminated by a ball of foul air. He urged the Qinghua Divine Light to barely remove it.

The clear and green light emitted by the Qinghua Divine Light attracted the ghosts in the darkness.

The ghosts were different from the creatures of the ghost path. The ghosts were actually evil creatures specially designed by the ghost path, born from the condensation of foul air.

Xuanming Sect has a secret place called Heavenly Ghost Prison, which should be connected to Huangquan Heavenly Prison, where there are many Heavenly Ghosts of various shapes.

At the beginning, Gao Xian relied on the Blood River Heavenly Venerable Transformation Book to transform the foul air, and killed many Heavenly Ghosts in Heavenly Ghost Prison, thus taking down Taining.

The Heavenly Ghosts in Huangquan Heavenly Prison are more like phantoms in form, condensing extremely thick foul air.

Such a powerful evil creature, even if a fifth-level cultivator looks at it from a distance, will be contaminated by the Heavenly Ghost's foul air. The special environment of Huangquan Heavenly Prison is a huge threat to the sixth level.

Gao Xian activated the Blood River Heavenly Venerable Transformation Book as a robe to protect his body and soul. Facing the large number of Heavenly Ghosts surrounding him, he directly activated the Broken Army Heavenly Evil Sword.

The Heavenly Ghost's foul air is too strong, and any artifact activated will be contaminated by the foul air. Even the Blood River Heavenly Venerable Transformation Book is very troublesome to dissolve this level of foul air.

The biggest advantage of the Broken Army Heavenly Evil Sword is that it will not be contaminated by foul air.

The black nine-pointed star flashed, and the deep and sharp starlight swept across the eight directions. The sky ghosts within a radius of tens of thousands of miles were instantly destroyed under the black starlight.

The evil spirit of the Pojun Tiansha Sword was too sharp, and its sharpness was enough to kill the seventh level.

These sky ghosts were only at the fifth level, how could they resist the power of the Pojun Tiansha Sword.

Gao Xian killed many sky ghosts, and he was relieved.

The Pojun Tiansha Sword would also accumulate foul air, but this foul air was transformed by absorbing the evil spirit. Only if it is not actively absorbed, the unparalleled sharpness of the Pojun Tiansha Sword is enough to kill all foul air and other external forces.

The most troublesome thing about Huangquan Tianyu is the endless foul air. Any cultivator who enters this world will feel strongly uncomfortable. Even if you rely on the secret method of the magic sect to temporarily support it, you must use your magic power when you are targeted by the sky ghost, and you will inevitably be contaminated by the foul air.

Gao Xian can solve these two most fundamental problems with the Xuehe Tianzun Huayuan Book and the Pojun Tiansha Sword.

In this way, he had almost no obstacles in Huangquan Heavenly Prison.

Huangquan Heavenly Prison was very vast. According to Gao Xian, it was much larger than Xuantai Heaven.

According to Jiu Da Ye, the Tai Chi Yin Yang Sword should be in the center of Huangquan Heavenly Prison, which was the place with the heaviest foul air.

As long as he continued to move forward along the foul air, he would always find the sword.

There were no other living beings in Huangquan Heavenly Prison, only the heavenly ghosts transformed from the foul air. In this world, the sun, moon, stars, earth, mountains and rivers could not be seen.

Everything was made up of endless foul air.

For normal cultivators, Huangquan Heavenly Prison was really like hell.

Gao Xian also spent his days in it like years. Every year or so, he would leave a physical body as a location. He returned to Qingyun Sect to recuperate for a few days and took the Pure Light Pill to clean up the foul air.

Fortunately, his flying speed was fast enough and he was not afraid of the foul air and the heavenly ghosts.

After more than 20 years in Huangquan Heavenly Prison, Gao Xian finally found the center of Huangquan Heavenly Prison.

This is a huge black vortex visible to the naked eye. The foul air has condensed into ink here. The heavy ink waves are rolling and rotating. The change of the foul air itself is enough to crush all living things.

The strong foul air blocked the Great Power Heavenly Dragon Imperial Seal, and Gao Xian could not see whether there was a sword or anything in the depths of the vortex.

After observing this huge vortex for dozens of days, Gao Xian used the Tai Chi Divine Image to break into the vortex.

The Tai Chi Divine Image has 80% of the power of the original body. With the blessing of the Tai Chi Wu Xiang Divine Cloth, it was contaminated and crushed by the foul air after only a few thousand miles.

This time, nothing was found. Fortunately, the Tai Chi Divine can condense again after twelve hours, so it is not a big loss.

After using the Tai Chi Divine Image to explore hundreds of times, Gao Xian did not find anything. He just figured out some laws of foul air changes in the continuous exploration and mastered some skills to resist foul air.

The foul air vortex is not only huge, but the violent changes in the foul air inside can even crush the pure yang consciousness. The sixth-level cultivator has no ability to go deep.

Even the Taixuan God who controls the Blood River Heavenly Venerable Huayuan Book can hardly withstand the foul air in the depths of the vortex.

It's not that the foul air has any mysterious changes, but the power of the gathered foul air is too strong. Gao Xian estimated that Xuanming Tianjun's cultivation is useless, and he will be crushed by the foul air if he goes in.

No, Xuanming Tianjun has no ability to go deep into the Yellow Springs Heavenly Prison. It's just that the foul air on the periphery is enough to block the seventh-level cultivator.

The most critical problem is that the foul air vortex destroys all perceptions, and the pure yang consciousness will be crushed. Taiji Shenxiang explored hundreds of times, and the scope of exploration was also very limited.

If the location of the sword cannot be determined, he may not be able to find the Taiji Yin-Yang Sword for hundreds of years.

Fortunately, a lot of human spiritual light has been accumulated in the past twenty years, which is enough to upgrade the Great Power Heavenly Dragon Imperial Magic Treasure Seal from expert to master level.

Gao Xian returned to the Shenxiao Hall and completed this upgrade.

The master level Great Power Heavenly Dragon Control Magic Seal doubles the observation range and power in all aspects. It even makes Gao Xian's consciousness grow a little.

Returning to the vortex of foul air again, Gao Xian once again differentiated the Tai Chi God Image and threw it into the vortex.

With the master-level Great Power Heavenly Dragon Control Magic Seal, the Tai Chi God Image can see through the deep and dark foul air and see the details of the transformation of the foul air flow.

With the experience gained in the vortex of foul air, the Tai Chi God Image continued to go deeper with the power of the flowing foul air. After going hundreds of thousands of miles deep, he finally saw the sword deep in the vortex.

The four-foot-long sword has been stained with a dark black by the foul air. The foul air around the sword showed a trace of black sharpness, like thousands of sharp black silk threads...

This is because the foul air has also been assimilated by the sword qi and transformed into a sharp state that can cut everything.

Gao Xian tested it several times, and the Tai Chi God Image would be cut into pieces by the black silk threads as soon as it approached. He tried to use the Pojun Tiansha Sword again, and finally he was able to cut these black silk threads.

However, these black threads were reborn and destroyed, almost endless. After the Pojun Tiansha Sword cut through these threads, there was only a split second to take the sword away.

Gao Xian didn't know if there was anything wrong with the sword, so he finally used the Taiji Shenxiang to control the Xuehe Tianzun Huayuanshu, while his main body was outside to activate the Pojun Tiansha Sword.

The black nine-pointed starlight shone, and countless black threads broke at the same time. The Taiji Shenxiang turned into a red light and threw it into it to roll up the black sword.

Gao Xian simultaneously locked the Shenxiao Hall clone and took the Taiji Shenxiang back to the Shenxiao Hall in an instant.

The Taiji Shenxiang, wearing a black and red robe, turned into a pool of black water in front of Gao Xian... The Xuehe Tianzun Huayuanshu was also pitch black.

The main reason was that the sword qi released by the black sword was too filthy, which made the Xuehe Tianzun Huayuanshu stained with filthy air.

Gao Xian's scalp numbed when he saw it. This thing was really evil. He hurriedly activated the Youzhou Order and ran to the Taiyi Hall.

Jiuzhou Ding saw Gao Xian's look, and he said nothing but waved his sleeves.

The next moment, Gao Xian was in the middle of a red flame, and the endless blazing fire around him made his whole body burn. In a trance, he felt as if he had turned into a piece of burnt meat inside and out...
