takes place in the same universe though i'm pretty sure it's wayyyy after the events of TTEOTM. the novel of TATMF mentioned TTEOTM briefly so it's not super connected, but both is center around a demon male lead
both stories take place in a fantasy world and share the same male lead, who also appears here in the role of a teacher and mentor guiding others
main lead turns into a villan expect in TTEOTM, it's the male lead. immortal sect/cultivators are also involved
LYST and CZ belong to the xianxia genre, share the same female protagonist, and involve more than one reincarnation
