I'll Try to Come Back Alive (6)

"Dad, are you okay?"

Hearing the unusual silence over the phone, Qin Chu was worried.

"Did she come back? Impossible… How can it be? No… it can't be her. If she came back, she'd have come for me."

Professor Lu mumbled the words repeatedly as if he had gone mad.

Qin Chu didn't catch all the words on the phone, other than the word "she"…

Who was she?

About a dozen seconds later, the call ended and the professor didn't call again. Qin Chu didn't dial back, guessing it was inconvenient for the professor to talk on the phone.

A while later, Gao Ran sent files about Zhao Qingya to Qin Chu's cellphone.
