In 3065 AD, Blue Star in the Nia Star System began operating interdimensional travel trains. These trains crossed time and space to enter fantasy worlds. Ye Zhiqiu, a student in Class 1, Grade 3 at Muyang Middle School, was on an interstellar adventure when he accidentally collided with a time-space train. Ye Zhiqiu died on the spot, but his soul merged with a time-space array disc and entered an interdimensional space, beginning the adventure that was his alone.
