Read it way back when the manhwa have not introduced the priestess princess yet, so out of sheer curiousity I searched for the novel and found it. Read ahead and so far, it's very good. World building is presented well and questions are slowly being answered regarding the parallel worlds, the summon and it's possible summons's abilities, and the perils of the upper floors. Highly recommend
