Chen Wenzhou had been waiting in the hotel above the cafe, and before Shen Heyu arrived at the cafe today, the person Chen Wenzhou met was Lu Yi.
As per the plan between Chen Wenzhou and Lu Yi, Chen Wenzhou lured Shen Heyu out, provoking her to drink a soda water laced with drugs while she was unaware.
After drinking the drugged soda water, she would lose consciousness in three minutes. Lu Yi had to seize this opportunity to call Shen Heyu and inquire about her location, with the legitimate excuse of wanting to know her whereabouts, and then come to find her.
After Lu Yi arrived, he could then take Shen Heyu to the hotel, and the two of them could 'cook the raw rice into cooked rice'.
Lu Yi had been pacing around the hotel all afternoon, thinking that Chen Wenzhou must have botched the plan. Several times he wanted to call Chen Wenzhou to ask how things were progressing; he was anxious and finally received a signal from Chen Wenzhou.
