What seemed like a casual slice-of-life story turned out to be very strange. Upon further examination, Qi Huantian found out that his mission wasn't as simple as playing out the story of the book he transmigrated into. There are multiple intertwined plot lines, tricky easter eggs planted by the author, and a connection between the FMC and the real world. One misstep and he'll lose out. Did you really think you can escape from your harem of death?
