When the passage was revealed, a black aura immediately flowed out, causing Yun Lintian and Xing Mo to frown.
"This aura…" Xing Mo frowned deeply. It was definitely the Abyssal aura he knew. Even though Xing Tengfei had cooperated with the Poison Valley, he didn't think Xing Tengfei would bring something contaminated with the Abyssal aura into his courtyard… What exactly happened?
Yun Lintian didn't think about it further. He immediately followed the staircases down and arrived at a small basement room filled with a dark aura. There was little furniture here, looking like a study room.
However, the aura was thin, as if it was about to dissipate at any moment. Without a doubt, there used to have something here.
Yun Lintian scanned the place with the Eyes of Heaven and immediately caught a glimpse of something inside a table's drawer at the corner.
