@Hifodo if you understand it. Can you explain the part that MC returns after 30 years and at starting point when MC was talking with heavenly demon and her granddaughter is there. Also after MC returns to murim and everyone says he returns after 30years whereas the little girl doesn't look old.
May the force be with you, child
