Chapter 573

Qin Mu currently has a very clear timeline.

"Actually, time can be deduced."

Qin Mu said.

"Really? Little Brother Qin, you've already deduced it?"

Liu Haoran's eyes lit up immediately.

Looking at Qin Mu was like seeing light in the darkness.

"It's like this, if Wang Ou didn't lie, and Zhen Gudong ate the two-hour sleeping pill at 9:15."

"The needle He Cha pricked made the medicine that should have taken effect in two hours now take effect in half an hour."

Qin Mu analyzed the timeline just now and the efficacy of the medicine bottle.

"Then the key is this needle, we must verify with He Cha what the effect of this needle is."

Liu Haoran looked up at Qin Mu.

"Right, is it effective immediately upon pricking or does it need time."

Qin Mu's analysis allowed Liu Haoran to further advance the case.

Just when Qin Mu and Liu Haoran had just reasoned out this cause.

Wang Ou, who was searching for evidence outside, discovered a book.

Inside the book it was written: The effect of the needle is to make the poison take effect immediately.

"Sigh, this book says the needle makes the poison take effect immediately, He Cha, what time did you prick the needle?"

Wang Ou, who discovered this secret, immediately asked He Jiong.

"I was at 9:45, so anyone who had contact with Zhen before me is a suspect."

"Right, it doesn't need two hours anymore."

He Cha immediately went into the room to tell the detective.

"This means the poison will change from two hours to ten minutes, so we can't push the time back to seven o'clock."

Qin Mu said.

"This is very possible."

He Jiong looked serious.
