Chapter 231: Why Did He Suddenly Change into a Different Person?

"My sister is missing, and your colleague? wasn't he supposed to watch her here?" Mu Yin stared at him emotionally, almost roaring out.

"Missing? Wait a second, I'll call and check..." The police officer was incredulous, hastily taking out his phone to call Xiaoguo.

Mu Yin also thought of something and almost simultaneously pulled out her phone to call Chi Ying.

The phone rang—

Mu Yin and the officer exchanged glances and quickly ran towards the direction from which the phone's ringtone was coming.

It was near the stairway entrance.

Mu Yin violently pushed the door open and instantly gasped in shock.

There Xiaoguo lay on the ground, stabbed in the abdomen with a knife, blood pouring out.

And his head was also injured, his condition unknown.
