The dense Nine Netherworldly Qi slowly emerged from the depths of the earth, surrounding the snow-capped mountains.
Looking from a distance, the white snow-capped mountains have turned black.
Not only that, the earth has also turned into a dark color, and Ye Chen can even vaguely feel that the water of the underworld is about to overflow from the earth.
The entrance where Ye Chen entered the Land of Underworld had long been infected by the black evil spirit and turned into a black pool.
A sinister aura spread out from these black pools, making Ye Chen feel a chill in his heart.
"Is the Twelve Heavenly Formation related to the Yellow Spring Land under the Kunlun Mountains?"
Su Xiyue was stunned for a moment and asked with a puzzled look on her face.
"If my guess is correct, the evil spirit in the land of underworld escapes from the ground because of the dragon veins. The land of underworld has not erupted so far because of the suppression of the dragon veins in Kunlun Mountain."
Ye Chen said in a deep voice: "Although the Twelve Capital Heaven Formation has nothing to do with the Land of Underworld, it has absorbed a large amount of Dragon Vein Qi, causing the power of the Dragon Vein here to fail, which indirectly led to the weakening of the power to seal the Land of Underworld.
This gave these evil spirits a chance to break through the seal."
"What should we do? The evil spirit in this underworld is extremely terrifying. If it really escapes from the underground world, the entire secular world may be in danger."
Su Xiyue's expression changed, and she said solemnly: "Besides, the Twelve Capital Formations have not yet been fully used. Once half a month later, Sister Gong and the others activate the power of the Twelve Capital Formations, I'm afraid they will absorb the power of the Twelve Capital Formations."
The power of the dragon vein will be even greater. Wouldn’t the seal here be broken?”
"It is possible that if the evil spirit of this underworld breaks through the seal, let alone Kunlun, even the West will not be able to escape this disaster."
Ye Chen took a deep breath, his eyes full of gloom.
I don’t know how long it took for this land of hell to be formed here, and the intensity of the evil energy in it is far beyond what ordinary people can bear.
Even a strong master cannot sustain it for too long under the Nine Netherworld Qi in this land of underworld.
If the Nine Netherworld Qi in this land of underworld spreads, it may cause the destruction of all living beings.
The most important thing is that the few grams of 3 dark ancient trees in the Land of the Underworld are already very powerful. If they emerge from the underground and swallow up the life force of the outside world, they may grow to an extremely terrifying state.
Ye Chen has always guessed that so many dark ancient trees are probably preparations for the resurrection of Immortal Qingyun.
With the ability of Immortal Qingyun, and with the help of the power of life in this dark ancient tree, there is a complete chance of resurrection.
If it really comes to that point, for Ye Chen, it may be much more serious than the arrival of Kunlun Xu.
"How could this happen? Now the arrow is on the string and we have to shoot it. Even if we notify several other major sects, I am afraid that it will not be possible to stop the operation of the twelve capital formations at this time."
Su Xiyue easily saw the essence of the matter.
Regardless of how big the threat is from this land of hell, the arrival of Kunlun Xu is already inevitable.
Even if Kunlun's virtual arrival may cause the seal of the Land of Underworld to collapse, this is an inevitable result.
"First let's see how dangerous this place is. Then wait for me here."
Ye Chen's mind moved and he appeared directly above the black pool, looking sharply at the pool below.
Perhaps because of the changes in the Land of Underworld, the restrictions in this valley have been destroyed.
Without the protection of this restriction, it would be easier for the Nine Netherworld Qi to escape.
However, the escaping Nine Netherworld Qi only surrounds the snow-capped mountains and has no tendency to escape in the distance.
Obviously, there is a strange force that Ye Chen doesn't know about, which suppresses the rules of this place and prevents these Nine Netherworld Qi from spreading endlessly.
Ye Chen slowly stretched out his right hand and pointed it like a sword, slashing towards the black pool.
Suddenly, a bright sword energy slashed out from Ye Chen's fingers, and struck on the black pool.
The black pool was cut in two by Ye Chen's sword energy, and the black Nine Netherworld energy suddenly retreated.
The middle of the black pool was split into two by Ye Chen's sword energy, leaving a way out.
At this moment, the roars of evil spirits suddenly came from the black pool.
I saw black threads suddenly shooting out from the black pool and winding towards Ye Chen.
"This thing actually came out of the River Styx?"
Ye Chen's expression changed, a sharp look flashed in his eyes, and with a movement of his mind, the Xuanyuan Sword appeared in Ye Chen's hand and slashed towards the thread in front of him.
The fierce sword energy soared into the sky and directly chopped the black thread.
"His power seems to be weaker than what I saw before. Is it because of the restriction?"
Ye Chen raised his eyebrows, a look of surprise flashed in his eyes.
In the Styx River before, the power of these black threads was much more powerful than it is now. It would be difficult for ordinary Yuan Condensing experts to deal with it.
Nowadays, the power of these black threads may not threaten even the best masters.
As the black thread was cut off, louder roars came from the surroundings!
As if something in the black pool was disturbed by Ye Chen's aura, gloomy auras began to revive in the black pool.
At this moment, the black pool suddenly became turbulent, a black vortex appeared in the center of the pool, and a large amount of Nine Netherworld Qi suddenly became violent.
More black threads, like hair, shot out from the black vortex and wound towards Ye Chen.
An evil spirit suddenly emitted!
Ye Chen raised a faint smile at the corner of his mouth. He was already prepared and retreated towards the distance as soon as his body moved.
After retreating a distance of hundreds of feet, Ye Chen was out of the attack range of these black threads.
Looking from a distance, black threads all over the sky shot out from the pool, almost covering the sky.
Just like the hair of a female ghost, it dances wantonly in the sky, and crazy murderous intent rises into the sky.
"I didn't expect that thing in the River Styx to have really come out. Now I'm in big trouble."
Ye Chen took a deep breath, a sharp look flashed in his eyes.
This guy can only survive in the River Styx. Since the black thread can appear from the pool, it is obvious that the River Styx has spread to this place.
With this guy guarding this place, let alone Ye Chen, even a strong man at the peak of Ningyuan cannot break through the Styx River and enter the land of hell.
The situation here is much more serious than Ye Chen imagined.
