Spoilers . . . I guess she is an important side character and i find it natural for him to be attracted to a female (he has soft spot only for beautiful female , for example he spares yu fei in blood forge continent arc and spoils the entire plan for her ) after a long time without intercourse in world realm. I have read till recent chapter where I saw him freeing a female cultivator ( she is in 2nd stage of ascended) he basically came to save a slave(male) whom he got the info through mind reading a scammer ('young looking guy 'is the supposed name author refers him). That slave haf low level cultivation but an extremely high lvl intent . So after he saves the slave and her . He tells her that he will come back to her . So I can tell that Wei wuyin has soft corner for only BEAUTIFUL WOMEN of course he is by no means a simp or a playboy who goes behind every women . So I find it natural for him to kidnap the female elf since he is consistent in his character .
