Nangong Zhen said with a hint of a smile, "Mr. Liu, please!"

"You just need to tell them how to place the stone slabs in the correct positions."

Old Liu picked up the stone slabs on the ground, carefully piecing them together, and moved a few of them before standing up and saying, "Try it!"

Nangong Zhen randomly pointed to a prisoner, "You, come here!"

The man walked forward tremulously, picking up the stone slabs one by one and stacking them into the door frame.

As the last stone slab was pressed into the vacant space, the original stone slabs arranged on the door suddenly transformed into a blood-colored vortex.

In the next instant, more than a dozen iron chains shot out from the vortex, locking onto the man's limbs and dragging him towards the vortex.

The man, weighing over a hundred pounds, was pulled into the air without any resistance and disappeared into the center of the vortex.

A horrifying scream echoed from the center of the vortex, but the vortex gradually shrank until it vanished completely.

Old Liu's expression was slightly grave, but Nangong Zhen laughed and said, "Mr. Liu is indeed extraordinary. I, myself, only managed to open the blood-colored vortex after nineteen tries."

"Mr. Liu was able to do it in one go. Truly remarkable!"

"Come, come... Let's continue, Mr. Liu. We have plenty of people in this inn. Please, feel free to proceed."

Old Liu unfolded his folding fan, "Shouldn't Mr. Nangong also show some sincerity?"

While Old Liu spoke, he was pondering something else.

Nangong Zhen said that he only managed to produce the blood-colored vortex on his nineteenth attempt at assembling the stone slabs, which meant that the traps appearing on the stone door were different for each of the previous eighteen attempts.

Moreover, Nangong Zhen already knew that there was more than one way to assemble the secret texts on the stone slabs.

His feigned surprise just now was clearly a test for Old Liu.

Nangong Zhen laughed and said, "Of course, of course... Please take a look, everyone."

With a wave of Nangong Zhen's hand, the bronze mirror emitted a burst of light, projecting the scene of the demon realm into the air.

The demon realm looked picturesque, like a paradise.

However, this tranquility felt inexplicably eerie.

Old Liu suddenly gasped, "The mountains and rivers here are dead!"

Nangong Zhen clapped his hands in admiration, "Mr. Liu, you truly have sharp eyes, hitting the nail right on the head!"

Before Old Liu could speak, someone in the projection said the same thing as Old Liu.

"The mountains and rivers here are dead. The water doesn't move, the trees don't move, they only have form, no life. Is this really the demon realm?" The speaker was Feng Ruoxing.

Qin Xin, standing next to Feng Ruoxing, also said, "I've heard people say that the places where demons reside are all blessed lands created by the gods, and even barren mountains and rivers have some spirituality. I can't feel any spiritual energy at all."

This time, only Qin Xin, Nie Xiaochun, Feng Ruoxing, and Wang the Butcher had entered the demon realm.

Yun Chang and Xia Mengying were left outside to provide support.

Wang the Butcher frowned and said, "Release the Nine-Tailed Fox and ask her."

Feng Ruoxing shook the Soul Restricting Pouch and poured the soul of the Nine-Tailed Fox onto the ground. Before she could get up, Qin Xin used a red rope to strangle her neck.

It was the demon-binding rope woven by Su Su using the secret technique of Qi Luck. Although it couldn't completely confine demons, it could suppress their Qi Luck and prevent them from escaping.

Qin Xin pulled back on the demon-binding rope, "Get up and take a look. What's going on here?"

The Nine-Tailed Fox said aggrievedly, "Sister, you've already caught me, and I can't escape. Don't be so fierce!"

Before the Nine-Tailed Fox could finish speaking, Wang the Butcher pressed his knife against her neck, "Put away your charms. We don't fall for that. If you dare to play tricks again, be careful I slit your throat."

"Okay!" The Nine-Tailed Fox blinked her eyes as if she was about to cry, but Wang the Butcher slapped her on the forehead with the flat of his blade, making her behave herself.

The Nine-Tailed Fox could charm all living beings, regardless of gender. Anyone who accidentally fell for her charm might fall under her control.

Fortunately, the current Nine-Tailed Fox was only a soul. Otherwise, Wang the Butcher wouldn't have dared to release her so easily.

The Nine-Tailed Fox looked around and her expression changed drastically, "Sister, you've come to the wrong place. Leave here quickly. This is the Burial Ground of Demons."

Wang the Butcher's expression changed upon hearing this.

As a descendant of the Butcher Sect, she had indeed heard legends of the Burial Ground of Demons, but no one had ever confirmed its existence.

Legend has it that some great demons who were hopeless in transcending tribulations but were approaching the end of their lifespan would find a place to bury their corpses before they died.

Just like some things in nature, they simply retained their original nature before they became demons.

In order to protect their bodies from being eaten by their own kind or skinned and dismembered into magical weapons, the great demons would set up many restrictions near their graves.

The Burial Ground of Demons was full of dangers, and even the God-Hand Explorers and tomb raiders did not dare to approach it easily.

In their eyes, demon tombs might contain countless treasures, but they might also be empty. Therefore, they were unwilling to risk gambling on what was inside the demon tombs.

That was why the Burial Ground of Demons had never been confirmed.
