"Anti-Japanese War Spy War + City + Space + Agent + Soul Traversing + Underbelly + Madness Literature", I anchored the background in Shanghai in 1938 - this "isolated island" where concessions and occupied areas are intertwined, and multiple forces are secretly fighting. It is not only a natural stage for spy wars, but also provides an excellent soil for "crazy disguise". The protagonist is set to be a modern top special character. The soul of a worker travels through the wealthy family of the Republic of China, the crazy young man. Space ability is the core golden finger (storage + healing + material reserve). "Crazy" is a weapon to protect and confuse the enemy. "Insanity" is the essential strategy of the modern soul. In the multiple strangles of the Japanese military's special high school, military command, central command, underground party, and puppet government, a thrilling spy war legend is performed step by step.
