What do you mean by saying that the corpses I sew are all ominous creatures?

I nodded to him, smiled gently, and didn't say anything more.

At this moment, Zhang Xuanqing squatted down next to a strange corpse, his brows furrowed tightly.

He used the tip of his longsword to pry open the tattered strips of cloth covering the strange corpse, revealing its deathly gray chest.

Something's not right.

Zhang Xuanqing's voice was very low, filled with suppressed anger.

We immediately surrounded them.

"Master Zhang, what have you discovered?"

Luo Pan adjusted his glasses and carefully examined the headless corpse.

Zhang Xuanqing pointed the tip of his sword at a deep, old wound on the corpse's chest, exposing the bone, and said coldly:

"This wound was left on me about two weeks ago."

Everyone was stunned for a moment upon hearing this.

Zhang Xuanqing stood up, his gaze sweeping over the other corpses on the ground, his eyes becoming unusually sharp.

"Two weeks ago, I infiltrated this place alone and fought with a group of men in black."

He pointed to the pieces on the ground: "I killed a few of them before I retreated."

I have absolutely no mistake; the fragments of clothing on these strange corpses, and the fatal sword wounds on their bodies, belong to that group of men in black!

Ling Shu stepped forward, put on medical gloves, and carefully examined the muscle texture and bones of the strange corpse.

"Master Zhang is right."

Ling Shu stood up, his face looking rather grim.

"These corpses had indeed been dead for some time before they were transformed into these monsters."

After listening to their conversation, my eyes narrowed slightly:

"If these corpse monsters were truly his doing, then it seems that the last surviving member of the Sang family has completely gone mad."

He not only experimented on living people, but he even harmed his own fallen comrades...

"A heartless and insane beast."

Shan Yan spat angrily onto the ground.

"Everyone, please be on your best."

Zhang Xuanqing gripped the longsword in his hand tightly, the lightning on the blade flickering faintly.

"If they can even use their own people as materials, what's behind the door is probably more dangerous than we imagine."

"Let's go in and see what they're up to!"

Stepping over the pile of grotesque, foul-smelling remains, we officially entered the space behind the bronze door.

Behind the door lies a vast underground space.

This is no longer the crudely excavated burial pits outside, but a huge sacrificial square that has been carefully restored.

The ground was paved with flat, blue flagstones. In the gaps between the flagstones, traces of dark red, dried blood had seeped into the texture of the stone.

It was as if countless horrific massacres had taken place here.

The entire space is topped by a huge dome.

The intricate star charts and totems are carved on it. Although the colors have faded, one can still feel the oppressive weight of the carvings.

Several beams of powerful flashlight beams swept across the empty square.

To everyone's surprise, this core area, which we thought should be heavily guarded, was still deserted.

There were no evil cultivators lying in ambush, no strange Gu formations, and not even the faint sound of a living person breathing.

Dead silence.

An absolute stillness that sends chills down your spine.

"There is no sign of any living person."

I closed my eyes slightly, spread out my sensory network, and carefully scanned the square before drawing my conclusion.

Upon hearing this, Zhang Xuanqing frowned even more deeply.

He carried his longsword and took a few steps forward cautiously.

"They're not here."

Zhang Xuanqing looked around.

"When I left half a month ago, there were still quite a few of them alive."

The door is now locked from the inside, but the person is nowhere to be found.

This is completely illogical.

Just then, the beam of the compass flashlight suddenly stopped in the very center of the square.

"Look there!" Compass's voice trembled slightly.

Following the beam of light, everyone's breath caught in their throats.

In the very center of the square stands a three-meter-high black polygonal altar.

The altar is made of a rare type of obsidian, with a smooth, mirror-like surface that reflects a cold, eerie light when illuminated by a flashlight.

At the very top of the altar, a huge stone coffin rests quietly.

The stone coffin was twice the size of an ordinary coffin, and its entire body was grayish-white, with countless twisted and struggling human faces carved on its surface.

It was as if countless wronged souls were sealed within it.

What is most shocking is that nine incredibly thick bronze chains are wrapped around the stone coffin.

The other ends of these chains were deeply embedded in the blue stone slabs beneath the altar, like nine giant pythons locking dragons, firmly pressing the stone coffin onto the altar.

Each bronze chain was covered with yellowed and even somewhat broken talismans.

I moved closer and my gaze fell on the black altar.

At the edge of the altar, I saw some dark red marks, a very familiar remnant of malevolent energy.

Although an unknown amount of time has passed and that malevolent aura has become very weak, the jade-colored malevolent aura within my body still resonates with it.

Those are the marks left by my grandfather.

Many years ago, my grandfather stood right here and used every means at his disposal to suppress what was inside the stone coffin.

"This is the core."

I said softly, my gaze following the chains upwards.

Suddenly, my pupils contracted sharply.

I discovered that three of the nine bronze chains wrapped around the stone coffin had broken in the middle.

The fracture surface showed signs of corrosion from some kind of strong acid.

And that enormous, greyish-white stone coffin...

Its coffin lid was not completely closed.

The coffin lid was pushed open with a gap about ten centimeters wide, and a dense, almost visible black aura of yin energy was silently spreading outwards through that gap.

However, this black, yin energy did not immediately dissipate into the air.

It seemed to possess some rudimentary consciousness, flowing slowly down the edge of the obsidian altar.

It silently swam towards us, following the path paved with bluestone slabs.

I squinted slightly, staring at the black mist spreading along the ground, and instantly understood.

This black, sinister aura was exactly the same as the lingering aura on the strange corpses that attacked us in the passage and the miasma forest.

It seems our guess was correct.

Those corpse monsters tainted by Yin energy and whose souls are forcibly locked are mass-produced using this substance.

However, the Yin energy emanating from the corpse monster was nothing compared to the Yin energy overflowing from the stone coffin; it was like a cheap product diluted with countless times the amount of water, completely incomparable.

Just as the black mist was about to reach our feet, Zhang Xuanqing, who was walking at the front, suddenly groaned.

He suddenly took half a step back, his previously calm expression instantly turning extremely serious.
