Just as Chen Shu turned around and walked elsewhere, he suddenly had a flash of inspiration and turned back to face the locked window.

"For secret room murder, whether it is the police or the murderer, the most important thing is to figure out where to enter and leave."

A burst of sophistication came from the corridor outside. Chen Shu turned around and saw his old classmate leaning against the door frame, looking at him with the corner of his mouth raised.

Chen Shu blurted out: "Chen Chuan, do you know?"

"You know what the heck!" Chen Chuan leaned against the door frame and laughed heartily, "I have been watching "Detective" in the past few days. I was so exhausted that I couldn't help but drink it."

Chen Shu mechanically raised the corner of his mouth, feeling that he was also stupid, how could he seek advice from this well-known young master in the bureau.

Looking back, when he focused his eyes on the window handle again, inspiration hit Chen Shu's mind like a rising tide on the riverside.

He looked down at his white-gloved hands, then glanced at the window handle nearby. For a moment, he was sure that he had found the key to the secret room.

In order to verify his thoughts, Chen Shu walked to the door of the room, took out his cell phone and turned on the timer, quickly ran from the door to the window, pulled the window's lock handle, and finally trotted back to the door.

I raised my hand and saw that it was only four to five seconds, which was 20% more time than the abnormal five or six seconds of Zheng Amei in the video.

Within six seconds, the window was locked, creating a secret room.

Zheng Jie's alibi is self-defeating.

Snapped!
Chapter completed!
