Nan Quanyou also worried for Nan Feng. He suddenly remembered, "Could it be the leaves of the red fruit? We've fed everything else, just not these leaves. The bamboo rat might be eating the leaves!"
The leaves?
Yes, why didn't Nan Feng consider this aspect?
It's true that all things in the world have their interactions, but the same things can also behave differently. For instance, someone who becomes heated after eating lychee can drink water steeped with lychee skin to cool down quickly.
Could it be...the antidote to the red fruit's poison is its leaves?
Nan Feng quickly plucked some leaves of the red fruit and fed it to the bamboo rat, then securely tied up its cage before going to bed.
That night, Nan Feng dreamt about the antidote, sometimes not finding it and her facial sores multiplying, and at other times finding it and returning to her former beauty.
...
The next day, Nan Feng woke before dawn. The first thing she did was check the bamboo rats.
