The first two chapters of the novel were inspired by the deeds of our ace agent Jin Wuzai. If you don't like it, you can skip directly to the third chapter and start the fantasy cultivation part! This book mainly tells the story of a nuclear weapons expert who travels to a different world to cultivate immortality, and saves the world with a nuclear weapon and an immortal sword (of course, nuclear weapons are not written as soon as they come out, there is a slow transition time). This book is rigorously conceived and logically logical. It is not a brainless novel. It requires readers to think carefully and read slowly. It is very different from the style of most Tomato novels, so please read with caution.
