I can push my cultivation progress to the end

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

At the same time, the black inner walls of this long tunnel were surrounded by spiraling, layered, and intermittently connected stone steps.

It felt as if it were leading to the netherworld.

Faced with this almost bottomless abyss-like tunnel, normal people would find it 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 couldn't even be considered a person anymore.

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

This was much faster than taking the stairs.

At the same time, during the fall, Li Hai could clearly feel the surrounding evil aura becoming increasingly浓郁, even surpassing the central area of the evil ground in Guojiapu.

From this, he boldly guessed that at the end of this tunnel-shaped evil ground, there might be a higher-level ghost beyond the Li Po level.

As Li Hai fell all the way to a depth of nearly a hundred zhang, he suddenly noticed several human corpses lying on one of the steps on the left.

So he immediately stopped in mid-air and flew towards them with a whoosh.

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

However, the rattan armor was now tattered, and the bodies under the armor were covered with large and small bloody holes, as if they had been pierced and bitten by countless snakes and insects.

"They are people from the Niujiao Town militia."

Standing on the steps, Li Hai turned the corpses over and examined them.

He found that the penetration depth of the bloody holes on these corpses was deeper than he had imagined, almost piercing through the entire body, and the coverage area was from head to toe.

"Is it the work of some kind of ghost that can control snakes or insects?"

While pondering, Li Hai was tempted to transform into a living person to see what the world looked like in this narrow evil ground.

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

Because Li Hai felt that if this place returned to reality after leaving the ghost eye vision, and instantly became a pure, solid underground rock layer, he would be crushed to death.

A hundred zhang of earth is not something that even the Steel Bones Realm can withstand.

Then Li Hai ignored the corpses, jumped off the steps, and fell again towards the bottom of the tunnel.

He fell all the way like this.

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

For no other reason than that he found several more corpses.

These corpses, also lying on the steps with bloody holes all over their bodies, were uniformly dressed in black double-breasted leather uniforms and black boots, and their clothes were all printed with a small 'Slay' character.

"Are they Demon Slayer Lieutenants?"

With curiosity in his heart, Li Hai flashed to the steps and began to study these corpses.

The main thing he studied was the martial arts realm they were in during their lifetime.

That is, the same level as Guo Huaijin.

"Could it be that Body Circulation…"

Li Hai pondered, "Is it the baseline for the combat power of the Demon Slayer Lieutenant group?"

After thinking about it, he thought it was indeed possible.

Because even the weakest Wraith-level ghost, when it is in an evil ground, its ability to kill and harm people is also at the level of Guo Huaijin, and it is even faster in terms of speed.

Only after leaving the evil ground will the danger of the Wraith-level ghost be greatly reduced, and then the martial artists of Guo Huaijin's level can truly defeat them completely.

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

In the subsequent falling process, he found corpses of Demon Slayer Lieutenants 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, with bloody holes all over their bodies.

"The cause of death is exactly the same."

Falling, Li Hai thought quietly, "It seems that there is probably only one ghost in this tunnel."

In the following falling process, Li Hai never found any more corpses.

And he finally reached the end of the tunnel after falling a full three thousand six hundred zhang.

This depth, converted into metric units, is nearly twelve thousand meters, completely surpassing the Mariana Trench on Earth, and it would not be an exaggeration to describe it as a deep abyss.

But in such a deep place, there was a wide training ground, and many rooms that were now dilapidated.

At the same time, the edges of this now mottled and dilapidated training ground were also covered with large mechanical parts similar to mine shaft elevators.

And these devices and many broken objects on the training ground were all printed with a small 'Slay' character.

So Li Hai immediately understood:

"So that's how it is. This training ground should be the underground facility of the Mingtang Pavilion, and those elevators are devices used to travel between the surface and the underground."

Under normal circumstances, the underground facilities of a stronghold would not be built in a place deeper than the Mariana Trench, even for defense against nuclear bombing, it would not be so outrageous.

So there is only one possibility, that this suddenly appearing evil ground forcibly dragged the underground training ground of the Mingtang Pavilion to a depth of more than 10,000 meters underground.

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

Li Hai's eyes scanned around, "Although it is very weak, it does exist."

Following the aura, he began to search the training ground.

Soon, Li Hai stopped outside a damaged room located on the edge of the training ground, which was now severely twisted and deformed.

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

Then Li Hai saw an old man leaning against a broken wall pier in the dark room, holding a broken steel whip and nearing death.

This old man was also wearing a black double-breasted uniform and a pair of black boots, but there were no bloody holes on his body, only a nearly half-broken wound in his abdomen, from which blood and intestines flowed out.

But even so, the person stubbornly held on and did not die, so Li Hai clearly saw all the personal interface information of this old man—

Character Name: Unknown

Strong Fragment: None

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

And at the same time that he saw this Demon Slayer Lieutenant, the other party naturally saw him as well.

So the old lieutenant sighed weakly:

"Alas, I never thought that in the end, it would be a ghost that sees Old Cha off."

"Hello."

Li Hai, who was recognized as a ghost by the old man, walked up to him and asked softly, "Are you Master Cha?"

The old man looked at Li Hai coldly without saying a word, obviously not wanting to say half a word to this ghost.

But at this moment, Li Hai actually took out a letter that was extremely familiar to him from his arms, and grinned:

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

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