Upon hearing Su Ya's response.
The young legend wasn't annoyed by her calling him by his full name; instead, he couldn't help but raise his hand to touch the mask on his face, confirming it was still there. He then flared his nostrils slightly, carefully sniffing at his robe sleeves, but didn't detect any scent—of course, not ruling out the foxes of Qingqiu Mountain having extraordinarily keen senses, able to smell what he couldn't.
Then, he looked at the little fox lady in front of him with some uncertainty and suspicion.
He was unsure how she discovered his identity.
It should be noted that even two years ago, when he was still a student who hadn't graduated from school, he was able to disguise his identity well in front of a vampire. There's no reason for Su Ya to recognize him right away now, especially since he's covered in a layer of legendary magic power.
