In modern society, science and technology are advanced, and the game industry is booming. The protagonist Lin Yu is a senior game player who is familiar with various types of games, and is especially obsessed with games with historical and mythological themes. On a rainy night, Lin Yu was driving home. In order to avoid pedestrians who suddenly rushed out, the vehicle lost control and hit a telephone pole on the roadside. Then his vision went dark and he lost consciousness.
When Lin Yu woke up again, he found himself in a strange world. The architectural style here is simple and the people wear ancient costumes. However, through communication with the people around him, he was shocked to find that this world turned out to be a "mixed world" that integrated many stories such as "Journey to the West", "The Romance of the Three Kingdoms", and "Strange Stories from a Chinese Studio". In this world, the four masters and disciples of Monk Tang have completed their pilgrimage to the West, and Sun Wukong has returned to Huaguo Mountain to continue his leisurely life; the heroes of the Three Kingdoms period have also left their own legendary stories, and the forces of all parties have waxed and waned; the monsters and monsters in Liaozhai live together with humans, some doing good and some doing evil. Moreover, according to folklore, there are still mysterious Ultraman and Godzilla on the remote Japanese island, and they occasionally affect the situation of this world.
Just when Lin Yu felt confused and helpless, a cold mechanical voice suddenly sounded in his mind. It turned out that it was a mysterious system called "The Master System" that bound him. This system told Lin Yu that he could obtain artifacts and skills by completing various tasks issued by the system, so as to survive in this dangerous and opportunity-filled world and gradually reach the top.
