Bab 421: Chu Kong and Silence

"Watch out for your step." Detective Tang said to her, and his voice echoed in the dark tunnel, which led downward. 

According to Detective Tang, this place was initially used as a basement but later used by his friend as his laboratory and living space.

"En." Li Caiyi hummed obediently. She could barely see her own hand, which was holding the edge of his sleeve, so she had no choice but to trudge blindly. 

They went down the stairs in silence. The air was humid, and there was a weird smell, like a mixture of rusty iron and dust. One couldn't help but feel suffocated when they were down here. 

The path was so narrow that it only allowed one person to go through. People had to walk in line to go in and out. 

Li Caiyi couldn't believe someone could really live down there. Even if she was paid, she would never agree to spend a night here. 

Sensing her apprehension, Detective Tang lightly tapped her hand. "We are almost there. Hang in there."
