Gu Youyou said, "I suddenly remembered something and wanted to ask you about it."
"What?" What an inopportune time to ask.

But for the sake of their future, she still asked, "You said that to become the State Preceptor one cannot marry, right?"
"Hmm," Jin Zijin didn't know what she was getting at.
"Does this count as an affair?"
"Ah...?" Jin Zijin was a bit stunned, but after a moment, he earnestly told her, "Of course not, we are doing this to detoxify, otherwise we'd have to drink blood."
"You're only fooling yourself with 'covering your ears to steal the bell'." Gu Youyou said irritably, "If others knew we sleep together every night and did nothing but detoxify, do you think they would believe that?"
"Of course they would," Jin Zijin confidently said, "Ajing knows, he's aware that we're detoxifying."
What an idiot.
