Feats of Memory

[CancerLuna]

I have just reread SPW and LHC's memory when learning Dugu 9 Swords is simply amazing. Are there any other memory feats from the other protagonists (or characters) that rival or surpass his?

One feat I can think of is HYS's wife and her photographic memory.

Wuji being able to identify Cheng Kun from a crowd of people, by recognising the sound of his cough, which he heard once while inside a bag after atleast 2 years or so.

Wang Yuyan's memory is pretty crazy, granted she learned all that since her childhood. But still, she knew all the mainstream martial arts of the central plains, she could recite an entire library from memory.

This. All from a girl who doesn't have any martial arts background.

And not just mainstream, she knew all the esoteric arts too. The only ones she didn't know are the extremely good ones that no one outside the org knew.

We can add Shi Potian to the list. His memory is superb.
