The thermos worked well, so the water temperature was perfect for drinking. Qin Zhi'ai took out a clean cup and poured some water into it before returning to the balcony.
The wall between the two balconies was wide enough that when Qin Zhi'ai stretched her arm out she still could not pass the water to Gu Yusheng.
She tried a couple more times but finally gave up. She pointed at the room behind her and said, "Master Gu, I'll send the water to your room."
Gu Yusheng turned her suggestion down. "No need, but thank you."
Assuming Gu Yusheng hadn't really wanted the water, Qin Zhi'ai responded, "Okay." She took a step back, preparing to say goodnight and leave the balcony, when suddenly Gu Yusheng, biting a cigarette between his teeth, walked to the wall between the two balconies, pushed aside a plant, and then jumped onto the wall by holding himself with one arm.
