The Secret of Substance X Luciel begins healing adventurers at the local guild. The adventurers agree to cease hostilities against clinics and change his nickname. Unfortunately, they change it to Saint Weirdo. Luciel gathers gossip from the adventurers; Brod has been forcing adventurers to train with him nonstop, Gulgar has been sneaking Substance-X into adventurer’s food, and several receptionists are getting married, worrying Luciel it might be Nanaela or Monika. Six months later Luciel defeats the floor 30 bosses, three Wights. His use of Substance-X is noticed by Cattleya and the Pope, who reveals it was invented by a Sage to unlock latent magic, but it was a failure; plus its real name is actually Gods Lament due to its foulness. The Pope predicts thanks to Substance-X Luciel may become a Sage within a few years. The Pope reveals the three wights were girls she once knew. Cattleya gives Luciel the official list of Substance-X’s effects; by sacrificing one of the three primal desires; food, sleep or sex, the drinker gains increased physical growth, skill enhancement and protection from illness. Luciel is horrified to realise, with his love of food and sleep that he must have lost his desire for sex, explaining why he is still a virgin despite being surrounded by beautiful women. He resolves to defeat the dungeon so he can quit Substance-X, fall in love and have lots of sex.
