A Journey Across All Realms

A retired special forces soldier chose to commit suicide when he was desperate. Unexpectedly, he was rescued by a jade pendant given by a stranger when he was a child, and it also helped him travel to other worlds. So with the idea of ​​​​going wherever I can, and a panda that is annoying to death, I went farther and farther on the journey. The stranger who gave him the jade pendant left only a piece of jade pendant and the vague words "I will meet you soon", and disappeared without a trace, never to be seen again. Who is the stranger? Can the two of them meet? What is his purpose? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
