Su Huaiyue and Wei Che sneaked into the basement silently. The air around them was icy cold, as if it was going to penetrate every pore.

Walking a few meters inside, the dim light cast flickering shadows on the stone wall, shrouding the entire space in a strange and mysterious atmosphere.

The lights flickered, as if ghosts were wandering around, making people feel a chill.

The two of them walked lightly and cautiously, fearing to alarm any unpredictable existence.

At this moment, Su Huaiyue's heart was beating like a drum, but her face was as calm as ever. Her eyes sparkled with alertness and wit like stars in the night sky.

Wei Che walked in front of her, his shoulders slightly leaning forward, his body as agile and steady as a tiger, his eyes as sharp as an eagle, as if he was ready to deal with any emergency at any time.

What came into view was a huge room with chains and shackles hanging on the walls. The rusty iron was faintly visible in the dim light.

The ground was covered with a thick layer of straw. Stepping on it felt like entering another silent world. The only sound I could hear was the faint sound of my own breathing.

The air was filled with an unpleasant damp smell, a mixture of decay and rust, which made people feel nauseous.

Su Huaiyue quickly gathered her thoughts, put all her fears behind her, and followed Wei Che closely.

The two hid in a dark corner that was not easily discovered, holding their breath and watching the movements in the room intently.

At this time, two messengers dressed in black appeared quietly, their faces hidden under the wide hoods, revealing only a pair of cold and ruthless eyes.

The two men dragged the unconscious official to a stone block that looked like an altar and skillfully placed the two men on it.

Then, one of the messengers pulled out a small bottle from his bosom. The bottle shone with an unsettling luster under the dim light.

They silently poured out some powder and forced it into the mouths of the two officers, their movements quick and precise.

"What on earth are these people doing?"

Su Huaiyue's heart tightened and she spoke in a low voice, with a hint of suppressed anxiety in her voice, as if every word was struggled out from the bottom of her heart.

But even so, her expression remained firm, without a trace of retreat.

Wei Che frowned, and the deep lines between his brows showed his inner caution and contemplation.

He patted Su Huaiyue's shoulder gently to comfort her and whispered, "It's definitely not a good thing. Keep observing."

There was a cold calmness in his tone, as if this dangerous scene would only inspire his fighting spirit.

After feeding the officer the medicine, the black-clad messenger turned around and dragged the officer into a dark room further inside.

Their movements were orderly, as if they were already used to it.

The room fell silent again, leaving only the dim light casting a lonely shadow on the wall, as if telling a secret. The door closed with an unsettling click.

Su Huaiyue and Wei Che wanted to follow in, but they were stuck by a mechanism on the wall and could not move forward.

"We can't do anything about the mechanism outside, but maybe we can find some clues in this room."

Wei Che encouraged.

The two men searched around unwillingly and finally found something unimaginable on the table: a few handfuls of animal feces of unknown origin.

[Ding! The system has detected bat droppings ahead!]

Bat poop?!

Su Huaiyue squatted down, looked at it carefully for a while, and wrapped it with a handkerchief while enduring the discomfort.

"What's this?"

Wei Che asked doubtfully.

"These are probably bat droppings, and they might be related to their conspiracy. Let's take them back and study them first. We might find something."

She said softly, a look of determination in her eyes.

"good."

Wei Che nodded, approving of her meticulousness.

The two retreated cautiously, and Su Huaiyue felt uneasy along the way.

When Su Huaiyue and Wei Che were about to leave, suddenly, the door of the dark room made a faint sound again.

The two of them hurriedly retreated to the corner and hid themselves in the shadows.

The door opened and the two messengers in black appeared again, but the two officers were nowhere to be seen.

Thin beads of cold sweat appeared on Su Huaiyue's forehead. She held her breath, her mind racing, trying to guess more conspiracies, while Wei Che beside her clenched his fists with a fierce look in his eyes.

Only when the footsteps of the black-clad messenger gradually faded away did they cautiously lean out.

Su Huaiyue whispered to Wei Che, "It seems that what these people are planning is more complicated than we thought."

"yes."

Wei Che nodded, but there was a hint of urgency in his tone.

"We must quickly uncover the secrets of the agency and see if we can rescue those officials."

Su Huaiyue pondered and stared at the mechanism on the wall.

Suddenly, a memory of reading a historical atlas before her time travel flashed through her mind.

"Perhaps, this is some special mechanism designed in ancient times." She whispered.

"What's the meaning?"

Wei Che looked at her curiously.

"This mechanism may require a specific method to open. Let me try."

Su Huaiyue took a step forward and gently ran his fingers across the patterns on the wall.

Then she began to adjust it, as if solving a complex math problem, gently twisting one of the protrusions.

Suddenly there was a creaking sound from the wall, and then a hidden doorway slowly opened.

Wei Che was slightly surprised, obviously shocked by Su Huaiyue's amazing discovery. Then he couldn't help but look at her. He didn't know if it was an illusion, but he always felt that she was hiding some huge secret.

"You actually opened it!"

There was a hint of approval in his voice.

Su Huaiyue smiled, and although she was nervous, there was also a hint of pride: "I didn't expect the knowledge in the illustration book to be useful."

She added solemnly, "Next, we have to be careful."

The two stepped into the dark room and felt a chill on their faces and the dim light.

Su Huaiyue observed the surroundings carefully, trying to find some clues that might guide them.

Wei Che remained alert at all times, always prepared to deal with any emergency.

"This place is set up like a prison cell."

The two stood at the entrance of the dark room. A strange stench emanated from the surrounding area, which made Su Huaiyue frown slightly.

"Look around for any clues."

Wei Che reminded in a low voice.

Su Huaiyue nodded, took a few steps forward, and caught a glimpse of two bodies lying on the ground. The bodies were shriveled and seemed to have been there for some time.

She murmured softly, "It seems someone got there before us and paid the price."

Wei Che squatted down and looked around the corpse: "If they are not officials, who are they?"

"Maybe it was someone who broke in by mistake."

Su Huaiyue no longer investigated and walked briskly through the narrow passage. Her intuition told her that there might be more discoveries ahead.
