He arrived in the world of science with a crappy system that tricked Conan into mining right from the start. Luo Tian never imagined that he, who thought he was a hunter, would actually become the prey. Xiaolan regarded him as a lucky star, Sonoko saw him as a potential stock, and Kisaki Eri would often ask him to dig wells... This book is also known as: "In Science, Conan was sold to mining right from the start", "Why do you have a system too?", "I am a succubus, but not a heartless well-drilling machine!"
