Ye Chen, an ordinary senior student, was supposed to be struggling with his graduation thesis in his dormitory, but he was accidentally involved in the mysterious organization in the rift of time and space - [Space-time Observatory]. The members here firmly believe that she is the best investigator in the station, "Ye Chen". Even if she repeatedly declares that she is not herself, she is only regarded as nonsense caused by amnesia. It turns out that the real investigator Ye Chen is not only extraordinary in skills, but also trapped in a strange amnesia cycle. The arrival of Ye Chen adds even more bizarre variables to this cycle.
In order to "recover his memory", Ye Chen was forced to join the observatory mission, and together with his wolf-eared Asian partner A Yue, square-headed omnic Xiao Fang, vegetable logistician Lao Zhou, and his spiritual boss Feng Ling who can hear the sounds of the world, they went to the newly discovered [Mushroom World] to perform a survey mission. This city-sized planet is full of giant mushrooms, and it also hides a world law that subverts perception - everything will appear visually pixelated.
The mission far exceeded expectations. There was actually an unknown dungeon buried under the surface. Not only did it contain "monsters" wrapped in mushrooms, but it also hid the secrets of the destroyed civilization. Mysteries such as "whether the real Ye Chen is dead", "the truth about the amnesia cycle" and "the disappearing administration behind the observation station" gradually surfaced through time and again time travels and adventures.
This is a journey intertwined with fantasy adventure, suspense conspiracy and warm bond. Ye Chen, an ordinary girl, struggles to survive in a strange world. She disguises her identity to deal with dangerous tasks while exploring the truth about herself and the world. Every choice she makes may affect the fate of the parallel world.
