After drilling into the tomb chamber, Li Hai immediately discovered that this was not a second-level tomb chamber at all, but a dark tunnel that went straight down with no end in sight.

At the same time, the dark inner walls of this long tunnel were surrounded by spiral, descending, layered stone steps that were either broken or continuous.

It felt as if it led to Hell.

A normal person facing such a seemingly bottomless abyss-like tunnel would find it very difficult to muster the courage to explore, and would not dare to walk down the steps one by one.

But Li Hai was not a normal person. No, he wasn't even considered a person now.

So Li Hai didn't take the steps at all; he simply free-fell into the dark tunnel.

This was much faster than taking the stairs.

During the fall, Li Hai could also clearly feel the surrounding evil Qi becoming increasingly dense, even surpassing the central area of the Evil Ground in Guo Family Fortress.

From this, he boldly speculated that at the end of this tunnel-shaped Evil Ground, there might exist a higher-Rank ghost monster that surpassed the Fierce Soul-level.

When Li Hai had fallen to a depth of nearly a hundred zhang, he suddenly noticed several human corpses lying on a certain step to his left.

So he immediately stopped in mid-air and swiftly flew over there.

Li Hai then discovered that these corpses were all wearing rattan armor.

However, the rattan armor was now in tatters, and the bodies wrapped within the armor were covered in large and small blood holes, as if they had been bitten and torn by countless snakes and insects drilling through them.

"They are people from the Niujiao Town militia."

Standing on the steps, Li Hai turned these corpses over and over to examine them.

He found that the penetration depth of the blood holes on these corpses was even deeper than he had imagined, almost piercing through the entire body, and the distribution range was from head to toe, everywhere.

"Was it caused by some kind of ghost monster that can control snakes or insects?"

While pondering, Li Hai had the intention to transform into a living person's state to see what the Human Realm appearance of this long and narrow Evil Ground truly looked like.

But after thinking it over, he didn't do so.

Because Li Hai felt that if this place, upon leaving the ghost eye vision and returning to reality, instantly turned into a purely solid, thick rock layer underground, he would be crushed to death.

A hundred zhang thick earth was not something that could be endured by the Steel Tendons Iron Bones Realm.

Immediately, Li Hai no longer paid attention to these corpses and leaped off the steps, falling once again towards the bottom of the tunnel.

He continued to fall like this.

When he had fallen to a depth of one thousand three hundred zhang, Li Hai once again hovered in mid-air.

For no other reason, he had found several more corpses.

These corpses, also lying on the steps with holes all over them, were uniformly dressed in dark black double-breasted leather tight suits and black long boots, and their clothes were all imprinted with a small 'Slayer' character.

"Are they Demon Slayer Commandants?"

With curiosity, Li Hai flashed onto the steps and began to examine these corpses.

His main focus was to study their martial arts Realm before they died.

Li Hai was very interested in this point.

Overall, martial arts is an art of developing and enhancing one's physical strength.

So even though these people were dead, he could still deduce their martial arts Realm by examining their remains.

After some study, Li Hai found that the Realm of these few people were all, without exception, Jingti Cycle.

Which was the same Rank as Guo Huaijin.

"Could it be that Jingti Cycle..."

Li Hai pondered, "is the baseline for the combat power of the Demon Slayer Commandant group?"

After thinking about it, he believed this was indeed possible.

Because even the weakest Ghost-level monster, when it is in the Evil Ground, its ability to kill and harm is also on the level of Guo Huaijin, and in terms of speed, it is even more rapid.

Only after leaving the Evil Ground would the harmfulness of Ghost-level monsters be greatly reduced, and only then would martial artists of the Guo Huaijin level truly be able to completely defeat them.

Immediately, Li Hai left the steps and continued to fall towards the bottom of the tunnel.

During the entire subsequent falling process, he discovered Demon Slayer Commandant corpses at depths of one thousand five hundred zhang, one thousand eight hundred zhang, and two thousand zhang, respectively.

And these corpses all died in the same way, covered in blood holes.

"The cause of death is completely identical."

As he fell, Li Hai quietly thought, "It seems there is a high probability that there is only one ghost monster in this tunnel."

Thus, in the subsequent falling process, Li Hai did not find any more remains.

And he, too, fell for a full three thousand six hundred zhang before finally reaching the bottom end of the tunnel.

This depth, converted to metric units, is nearly twelve thousand meters, completely surpassing the Mariana Trench on Earth; describing it as an abyssal Hell is no exaggeration at all.

But in such a profound place, there existed a spacious training ground, as well as numerous now dilapidated rooms.

At the same time, around the edges of this now equally mottled and decayed training ground, there were large mechanical components similar to mine hoists.

And these devices, as well as many damaged objects on the training ground, were all imprinted with a small 'Slayer' character.

Li Hai immediately understood:

"So that's it. This training ground should be an underground facility of Mingtang Pavilion, and those hoists are devices used for passage between the ground and underground."

Under normal circumstances, an outpost's underground facility would not be built to a depth greater than the Mariana Trench, even for defense against nuclear bombs it wouldn't be that absurd.

So there was only one possibility: this suddenly appearing Evil Ground had forcibly dragged Mingtang Pavilion's underground training ground to a depth of over ten thousand meters underground.

"There is the Qi of a living person here."

Li Hai's gaze swept around, "Although very weak, it definitely exists."

Following the Qi, he began to search this training ground.

Soon, Li Hai stopped outside a severely twisted and damaged room located at the edge of the training ground.

In such a dangerous environment, he did not risk transforming into a living person's form, but instead, his illusory form directly passed through layers of obstacles and entered the room.

Then, in this dark room, Li Hai saw an old man, nearly dying, leaning against a broken wall pier, holding a broken steel whip.

This old man was also wearing a set of double-breasted dark black tight suits and a pair of black long boots, but there were no blood holes on his body; only his abdomen was nearly half-severed, with blood and intestines flowing out.

Yet, despite this, the man stubbornly held on and did not die, allowing Li Hai to clearly see all of this old man's personal interface information—

Character Name: Unknown

Rank: Zhengchuan Martial Arts → Steel Tendons Iron Bones, Qimen Arts → Spiritual Focus Roaming

Skills: "Hercules Throwing Elephant Technique," "Raging Dragon Whip," "Seeking Ghosts and Tracking Monsters," "Yin Yang Eyes," "Advanced Yuan Breath Refining Yang Method," "Lifespan Reduction Technique," "Heavenly Blaze Drawing Yang Technique," "Shangyuan Spirit Suppression Talisman (Incomplete)"

Trait Attributes: 【Strong Soul Level 2】 【Physical Strength Level 2】 【Fury Level 2】 【Inspiration Level 2】 【Yang Absorption Level 2】 【Spiritual Focus Level 2】 【Mana Level 2】

Strongest Fragment: None

In an instant, Li Hai learned all of this person's Cultivation Technique.

And as he saw this Demon Slayer Commandant, the other party naturally saw him too.

So the old commandant sighed weakly:

"How tragic. I never thought that in the end, it would be a ghost monster to send off old Tea."

"Hello."

Li Hai, who was mistaken for an evil ghost by the old man, walked up to him and asked gently, "Are you Master Tea?"

The old man looked at Li Hai coldly without saying a word, clearly not wanting to speak a single word to him, a ghost monster.

But at this moment, Li Hai actually pulled out a letter from his Arms that was extremely familiar to the old man, and grinned:

"Believe it or not, Zhang Miaoji invited me to join your Demon Slayer Division, saying he wanted me to... slay ghosts and eliminate demons, and bring benefit to the common people."

Looking at the letter and hearing these words, the old man was instantly dumbfounded.
