It was He Yang's cell phone.
Shen Xiuzhu reached for the phone and found that the call was from Xu Chengyan.
The phone was still vibrating, Shen Xiuzhu looked at the words "Xu Chengyan" on the screen, and moved his fingertips casually.
Then, he hung up the phone without hesitation.

Accidentally ate what he's allergic to? Sounds like the white moonlight is a white lotus instead.
