She Slept, How Could She Not Have Evidence?

"Yes, it's about the new drug you mentioned…"

Cheng Tingxue stammered.

"What is the actual effect of that drug?"

This question was extremely important to Jiang Chengxi!

Now that things had come to this, Cheng Tingxue had nothing to hide.

She could only answer truthfully. "That drug… Not only can it make a man have a certain reaction, but it can also confuse their minds. If it weren't for Young Master Yi's stubbornness in keeping things clean, I wouldn't have used that drug… This is also something Madam Rong has silently agreed to!"

"How long does the drug last?" Jiang Chengxi asked.

"The clinical trial states twelve hours."

Jiang Chengxi was silent.

He watched the surveillance footage a few times in the end.

Besides confirming that the man above was Rong Linyi, she also had to confirm Rong Linyi's mental state at that time.

That night seemed to be a coincidence.
