Just then, a knock sounded at the door.
Tang San walked in.
He wore a fitted black outfit, and his hair was slightly disheveled. He had clearly just emerged from cultivation.
The instant he saw Yu Xiaogang, his steps faltered slightly. A faint chill flashed through his dark eyes, but he quickly concealed it.
"Teacher." Tang San's voice was calm, betraying no emotion.
