Also in the beginning of season 2 they say that after the war feng tian yi n yi fuling went to seclusion as husband n wife never a mention abt that yi fuling is “dead” n feng tian yi was searching for her. N in season 1 it mention abt how long he waited ish 3000 days n never abt a baby girl??? Is it just me or am i missing something???

So question in season 1 when bai tian jun kiss yi fuling n both “died” how come in season 2 feng ru che is the daughter of feng tian yi n yi fuling?
