"Tong Jiuyou? Are you sure?" Youhun Zhenren seemed somewhat taken aback.

Of the three minor supernatural abilities of his Youxuan sect, ranked by difficulty, Tong Jiuyou is the most difficult to comprehend.

Many true masters initially choose "severing the life force," as this supernatural power is the easiest to comprehend.

The next best is the "Soul-Capturing Dream," which even true disciples can only comprehend in a few cases.

As for "connecting to the Nine Netherworlds," those are extremely rare...

Even Youhun Zhenren himself, having only comprehended "Severing Life Force" and "Capturing Soul Dream," was already a person of exceptional talent and ranked among the Zhenren.

Of course, those who can comprehend "connecting to the Nine Netherworlds" are not necessarily one in ten thousand geniuses.

In the history of the Hidden Moon Sect, some people have been able to comprehend it, but the vast majority of them only achieved a certain affinity with this particular supernatural power. Those who could comprehend and integrate all three supernatural powers are extremely rare...

"I'm sure!" Chen Yi nodded firmly.

His reason for choosing this supernatural power was also very simple.

Because he had already mastered a minor supernatural power called "Earthly Yin Wrathful Fire Form," which sounded quite compatible with "Connecting to the Nine Netherworlds."

"I still want to give you some advice: young man, do not be overly ambitious," the Ghostly Immortal advised. "However, since you have made up your mind, I will not try to persuade you any further."

Since he was Xuanzhu's disciple, not his own, and he had tried to persuade Chen Yi without success, he decided to let him be.

"You can't take the minor supernatural powers with you; you can only comprehend them in a fixed place. Go through that door over there!" Ghostly Immortal instructed.

Chen Yi looked down at this floor and found that it had twelve doors.

If we consider the four major factions of the Hidden Moon Sect, each with three minor supernatural abilities to inherit, then the total number would be exactly twelve.

"You have six hours. If you cannot comprehend it, it proves that you are not destined for supernatural powers."

"12 hours...?"

Chen Yi discovered that some long-lived old monsters liked to use time to measure things.

Perhaps it was because they were young, or perhaps they had more specific times of day, but they eventually got used to it.

He nodded: "Thank you, senior!"

After saying that, he walked toward that door.

The door was protected by very tight restrictions. Chen Yi glanced at it with his "One Glance at the Array" skill and almost lost his sight.

Such a complex formation would probably require him to reach level 3 in formation mastery before he could decipher it.

However, even if one sees through the restrictions here, it will be useless, since there is a Golden Core cultivator guarding this place, and it is impossible to enter and learn supernatural powers at will.

Even if those guys from the Thief Heaven Sect came, they probably wouldn't be able to succeed.

"Boom!"

The stone door suddenly flipped open, pushing Chen Yi inside.

What comes into view is a quiet and secluded scene.

Chen Yi looked somewhat surprised.

This space is somewhat similar to the dream space I entered.

He was certain that what he was seeing was not reality, but some kind of illusion.

Otherwise, the size of the library would not be able to accommodate such a large space.

"......"

However, since the goal is to comprehend minor supernatural powers, it must be related to the environment of this place.

Chen Yi began to carefully observe his surroundings.

Here, the mountains are barren, the peaks do not reach the sky, the ridges are impassable, the caves do not hold clouds, and the streams do not flow.

He walked deeper into the area for a long time and suddenly came across a stone tablet.

The inscription reads, "Mount Xuwei, a place of pure Yin with no Yang."

Behind the stone tablet, a cold wind whistled and a thick black fog hung in the air.

There were no cries of birds or beasts in the air, but occasionally some deformed black shadows flashed before my eyes.

"Go back. This is not a place for you."

"Your yang energy is so strong that it shines like a golden wheel in this place, and evil spirits see you as food for them."

Chen Yi heard a voice echoing in his ears.

He pursed his lips. "I came here to comprehend supernatural powers. Wouldn't it be a waste of my time to go back?"

"Heh heh heh! Interesting kid, you weren't scared off! Well then, why don't you give it a try!"

"This place has nine levels, each guarded by a powerful ghost. If you can connect all nine levels, you can comprehend the divine power. Let alone the early Foundation Establishment stage, even the late Foundation Establishment stage might not be able to descend all nine levels in one go..."

Chen Yi bowed slightly to those behind him: "Thank you for your guidance, Senior Ghost!"

"......"

The eerie voice fell silent.

Yes, that voice did indeed come from the Ghostly Immortal.

Although he had advised Chen Yi against it, Chen Yi was, after all, a disciple of Xuanzhu, so he naturally wanted to see what this young man was really like.

Those whose resolve is not firm will not dare to go any further after seeing the demons and monsters behind the stone tablet.

Chen Yi's eager-to-try appearance left Youhun Zhenren speechless.

Where did Xuanzhu find such an arrogant disciple?

Wasn't the previous female disciple, Su Xin, quite composed?

It's true that old people tend to get confused...

While the Ghostly Immortal remained silent, Chen Yi had already entered the black mist.

Sure enough, in an instant, a swarm of ghostly figures attacked him.

Lightning appeared in his palm, and a bolt of lightning shot out from his palm.

"Smack!"

Those ghostly figures vanished instantly.

The wails echoed through the black mist.

As he ventured deeper into the valley, he came to a canyon.

In the middle of the canyon, a burly figure wielding a rusty broadsword awaited him.

"Whoosh!"

The figure took a step and then disappeared.

Chen Yi suddenly felt a chill run down his spine.

He reached his palm backward.

"boom!"

A flash of lightning, and the ghostly figure's head split open like a watermelon.

It had no head, yet it was still wildly swinging its knife.

Chen Yi decisively fired several more palm lightning bolts, shattering his body.

That's it?

It should be noted that this palm lightning is not even a spell; it is merely a portion of the demonic power he obtained from the Thunder Ghost Crimson Gold Python.

The ghost sent by the Ghostly Immortal to observe trembled.

So decisive and efficient?

"The ghosts on the first level are only at the early stage of Foundation Establishment, nothing special..."

But then Chen Yi showed him with his actions what it meant to be invincible among his peers.

"Slap! Slap!"

The second-level guardian spirit is dead.

"Slap! Slap! Slap!"

The ghosts on the third floor also died.

And so, Chen Yi continued onward.

It wasn't until the sixth floor that he gradually began to feel a bit hot.

The Ghostly Immortal's mouth went dry as he watched: "This boy's talent is truly rare!"

He was incredibly envious; the old ghost Xuanzhu had actually found such a successor.

After a fierce battle, Chen Yi killed the ghost on the sixth floor.

A fragment entered his mind.

These are some insights about "connecting to the Nine Netherworlds".

From the beginning until now, we have collected six insights into supernatural powers.

The amount of information increases as you go further in.

Chen Yi took a deep breath. Now, the supernatural insights in his mind had begun to merge, giving him a certain understanding of this minor supernatural ability.

This supernatural power borrows the power of the Nine Netherworlds and ghosts to fight the enemy, while the user hides in the black mist, making it extremely sinister.

"Could this Hidden Moon Sect be some kind of demonic sect?" he asked with a strange expression.

He continued to delve deeper.

When they reached the seventh level, the ghost's strength was comparable to that of a late-stage Foundation Establishment cultivator.

After the battle, Chen Yi felt that his spiritual energy had been greatly depleted.

Just as he was about to absorb the surrounding spiritual energy to replenish himself, he discovered that he was only inhaling the ghostly energy of the Netherworld.

Not only does it not replenish spiritual energy, but absorbing too much of it will turn a person into a ghost...

His face darkened. That was indeed insidious!
