Transmigrating into a female supporting role in a book

I only heard the sound of metal colliding, and he seemed to be opening a door. Then, the heavy iron door was pushed open, and a cold air came out from inside and fell to my feet, freezing me so much that I sneezed twice on the spot.

"What is this place?" I couldn't help but hug my arms.

Sun An didn't say anything, but took out a cloak made of animal skin that he didn't know was hidden there and put it on me. Then he took out a torch and led me inside.

After I followed him in, I saw that this seemed to be a carved-out stone cellar. The walls were irregular, and there were some counters, tables, and chairs placed on it. There were also a lot of miscellaneous tools on the largest table. I couldn't see it very clearly under the dim light.

"Huh——" Suddenly, a muffled gasp and the sound of iron chains clinking were heard coming from nearby.

I immediately hugged Sun An's arm and asked, "What, what's that sound?"

He pointed to the opposite side and found that there was another stone chamber in the cellar.

But I always felt that his expression was like he was hiding something, waiting for me to discover it, which made me a little scared. "What's in there?"

"You'll know for yourself." He smiled, and that smile became a little sinister in my eyes.

"If you scare me, I will be angry too. Really angry..." I tried to remain calm and not let my voice tremble.

But he repeatedly urged me to go and take a look myself.

Although she was obviously very scared, she didn't know why she actually listened to him and walked towards that direction step by step.

He stood at the door and lit the torches in the room. Then the light became brighter and I stepped in.

I thought the sound was from some wild beast, but when I came in, what caught my eye was a person, a naked person with chains tied around his arms and neck, nailed to the wall.

I looked at Sun An in shock, but he didn't seem to think there was anything wrong with it. "You're using living people for experiments?"

"Take another good look," he reminded calmly.

I shifted my gaze back. The man had disheveled hair that covered most of his face. Judging from his body, he was a well-maintained adult man, but his skin seemed a little too white, and there was a white...scar on his left chest?

He looked like he was drunk, with his head hung and a low groaning sound coming from his mouth, which sounded like he was sighing or imitating the roar of a wild beast.

As a normal person, I feel a little cold in this place even when wrapped in a thick coat. Doesn’t he feel cold with his naked body?

Seeing that he was tied up with an iron chain and didn't seem to be dangerous, I boldly took two steps forward, wanting to take a closer look at who he was.

Sun An reminded again, "Don't get too close, the corpse is poisonous."

"Corpse...corpse?" I quickly caught the key words in his words.

Sun An nodded, "Yes, this is a corpse."

My scalp went numb for a moment and I took a few steps back. “But why is he still moving?”

"I don't understand this either, so I locked him here and wanted to study it slowly." He explained softly.

Coo, cluck, cluck... A strange sound suddenly came from the corner, like someone laughing shrilly, or like the chirping of some birds.

This sound made the corpse in front of me suddenly active, as if it wanted to struggle to do something, and the iron chain made a loud noise. I continued to retreat, but I saw an iron cage in the corner with a black thing curled up inside.

What kind of monsters did Sun An hide? I screamed and wanted to run away, but when I passed by the corpse, he suddenly broke free from the chain on one arm, reached out and grabbed me, and pulled me in front of him.
