Because on Wu Nian's body, apart from that face, he couldn't see any traces of Shen Nie or Wu's past.
This was the most confusing thing for Kang Chen. If Wu Nian was any one of them, even with amnesia, it would be impossible to completely erase all of his habits.
Xizeer asked, "Dad, several times during dinner, you seemed absent-minded. What were you thinking about?"
Kang Chen sighed, "I was wondering if there's a third person in this world with a face like Shen Nie's?"
Xizeer immediately caught the crux of the matter, "Third face, what do you mean?"
Kang Chen ruffled Xizeer's hair, "It means exactly as you heard it. There used to be someone with an identical face to Shen Nie's, so similar that if they didn't speak or move, perhaps I wouldn't be able to tell who was who."
Xizeer was shocked, "Who was that person?"
