Just like the matter with Qiu Tu this time.
Faced with Zhao Ji's questioning, he didn't try to forcibly explain: What's the use of explaining? Would Zhao Ji believe him? Over the years, when has Qiu Tu ever been able to deceive Zhao Ji?
Moreover... the most important thing. If he forcibly came up with a reason, how would he undress next time to heal? How would he enjoy the benefits?
So... he spoke not a word about the reasons. Just said he cared about Zhao Ji, felt for Zhao Ji. Seeing Zhao Ji hurt was like having his heart cut by a knife. He directly moved Zhao Ji with genuine feelings.
Even when Zhao Ji later pressed him for answers, he just casually made up a few reasons, and never spoke definitively.
—Anyway, he also said he didn't know the reason. It's all speculation.
Since it's speculation, there are certainly right and wrong answers. If guessed wrong, it can't be counted as him lying.
Moreover, next time while healing, he could undress, could cuddle.
