After the Demon King's battle, the snow field returned to tranquility.

The depths of the ice are filled with dead silence.

Yan Sushi sat cross-legged, silently contemplating the formation path and the secret techniques of exercises.

Her talent in the formation is extremely high, in just a few months, she has mastered more than a dozen low-grade formations, compared to it, the cultivation of the secret art of the exercises is much slower, and she has not been able to comprehend the Benyun hand so far.

Gu Xiuyun sat on the other side, deducing the Zhongpin formation.

Suddenly, there was a creaking sound in the ice.

"What's going on?"

The two of them opened their eyes in unison and looked around.

I saw that in the ice crack not far away, there was a faint black gas appearing, immersed in the ice, dyeing the pure white ice gray.

"That's ...... Evil spirits?"

Gu Xiuyun's face changed suddenly.

How hard is the 10,000-year-old ice, how can ordinary air currents penetrate into it? Even if it is refining the sword qi, it can only penetrate half a foot deep.

But the black gas in front of me was like ink spilling into running water, without any obstacles, and it was easily covered with a large layer of ice.

What else could have such power but evil energy?

He hurriedly urged the spirit tortoise black armor stick, and sure enough, what the heavenly machine was pointing to was the evil qi.

"How can there be evil qi here, could it be that there is a leyline hidden under the ice? Those two demon kings fought and shook open the cracks in the earth, so the evil qi seeped out from the leylines?"

The corners of Gu Xiuyun's eyebrows raised slightly, and he continued to urge the hexagram to explore the source of the evil qi.

If there is really a leyline here, it is likely that it has not been discovered by the four great sects, after all, under the ice layer of thousands of zhang, and deep into the snow field, who can find it?

A leyline that has not been looted is definitely a treasure.

"Gu Xiuyun, what is the evil qi?" Yan Sushi asked.

"A very terrifying mist, you be careful, don't be touched by it," Gu Xiuyun said in a deep voice, "If there is a evil qi approaching, immediately take the cold jade essence, and then urge the spiritual power to resist, you must not rely on the physical body, otherwise it will take away the vitality of the physical body, and life and death are unpredictable." ”

"So powerful?" Yan Sushi's face turned pale.

"When the evil qi is the beginning of the opening of heaven and earth, the turbidity is dissolved, and there is a magical power that destroys the vitality of all things and returns to the source, which is naturally powerful. Gu Xiuyun explained.

Hearing this, Yan Sushi immediately looked around, lest any evil qi seep out of the ice and approach her.

The spiritual power around Gu Xiuyun's body surged, and the spirit tortoise black armor skewer danced out of thin air, drawing out countless strange symbols.

Suddenly, the fourteen hexagrams stopped at the same time, all pointing to the southeast side of the ground.

"It seems that the source of the evil qi is there," Gu Xiuyun's eyes lit up, "Miss Yan, you wait here, don't move around, if you can't stop the evil qi, just hide in the cold yin array, and you can support it for a long time." ”

As he spoke, he swung several palms in succession, shattering the ice in front of him and walking deep underground.

The 10,000-year-old ice should have been extremely hard, but after being infiltrated by the evil qi, the structures inside it have been destroyed, and at this moment, it is slightly inferior to ordinary ice cubes, so it naturally can't stop the palm power.

Pong!Pong!Pong!

The ice layer continued to shatter, and in just half a pillar of incense, Gu Xiuyun had already penetrated into it.

The closer they got to the source, the more intense the evil qi in the ice became, and if they were other cultivators, they would have already been forced to turn around and flee by the evil qi, and they didn't dare to go any deeper.

But Gu Xiuyun had already comprehended the spiritual armor technique, and the spiritual power armor around his body was extremely tough, even if he stood in the thick of the evil qi, he would not lose a single bit.

Fusion of five prohibitions, the power is much stronger than the four prohibitions.

If the fusion of the four prohibitions is still in the realm of the secret law, then the five prohibitions are already close to the true Dao.

Therefore, even the disciples of the Traceless Sect rarely fused the five prohibitions and cultivated the secret method to perfection, and even if there were, most of them comprehended the killing secret technique, not the spirit armor technique.

After all, in terms of the difficulty of cultivation, methods such as Benyun Refining Light Fingers do not need to maintain the stable existence of the fusion prohibition, so the difficulty is naturally lower.

After walking for another three thousand zhang, Gu Xiuyun saw the source of the evil qi.

It was a huge spherical cavern.

At this moment, a crack opened in the cave, and the smooth cut mark faintly revealed a cold glow, Gu Xiuyun walked into the cave along the crack, looking around.

The cave is shaped like an egg, and the surrounding stone walls are covered with formation patterns, and there are dense array flags.

At a glance, there are tens of thousands.

At the bottom of the center of the cave, there was a dark and bottomless well, exactly like the abyss in Youning City, and it was constantly oozing evil energy.

"It seems that I guessed wrong, this is not the leyline, but the abyss that has been sealed for countless years. ”

Gu Xiuyun was thoughtful.

The surrounding array flags were close to decay, and the formation patterns had almost been smoothed, so it could be seen that the sealing array here was already close to collapsing.

Even if the two demon kings didn't fight here, at most three thousand years, the sealing array would collapse.

And it just so happened that one of the demon kings used his sword light magic power to break through the earth, piercing into the depths of the ground all the way, splitting the egg-shaped cave, so that this place would appear early, and the evil qi would permeate the ice.

The cave is filled with a rich evil aura, such a huge evil aura, once it all leaks out, it is enough to destroy most of the snow field, the demon beasts have spiritual power to protect their bodies, and they can naturally resist it, but those ordinary creatures will be killed and injured countless times.

Gu Xiuyun walked to the stone wall of the cave and carefully observed the form of the array flag.

He had read many classics in the Traceless Sect, and he also knew that the formation flags used by the four great sects were different, and many times as long as he observed the array flags, he could see the origin of the other party.

But the array flag in front of him was completely different from the four great sects, and it was completely from another school.

"Could it be that I guessed wrong?" Gu Xiuyun hurriedly glanced around, observing the formation patterns in the cave wall.

After a long time, his eyes lit up.

"The formation on the stone wall is not used to seal, but to guard. ”

"Could it be that this is a Guardian Array, in order to protect the abyss?" Gu Xiuyun turned his head to look at the bottomless pit in the center of the cave, "Since it is a Guardian Array, then the bottomless pit here may be able to lead to a secret place? If this is the case, it is also worth exploring." ”

The abyss under Youning City, although it is connected to the depths of the earth, but at its end is a Jedi, as early as countless years ago, there were Douxiao Realm powerhouses who entered it to investigate.

Eventually, the mighty man was trapped in a Jedi and died in the depths of the abyss, leaving behind only a few last words, which were sent through the messenger.

Since then, no cultivator has dared to go deep into the abyss under Youning City, and even the four great sects have given up on this place.

"According to the records of the Traceless Sect's classics, the abyss under Youning City belongs to the Death Cave, and the abyss behind Beiqiong Mountain is the Spirit Cave, so the Weak Water Sect will continue to send disciples to investigate. ”

After entering the Traceless Sect, Gu Xiuyun had read many classics, and the Traceless Sect did not have any restrictions on the books of wild history and miscellaneous talks, so he read a lot.

I also know that there are many bottomless abysses in the secret realm of demons.
