Opening an Inn in the Martial Arts World, the System Makes Me an Immortal

Other people's family traveled through time and were suppressed for a lifetime, but I traveled through time and both my parents died. Other people's time-travel systems are awesome, but my time-travel system has serious problems. Even if the system is not serious, the inn employees are not normal people either! I just want to be a salted fish, cook, read books, drink tea, and earn a little money. If I could choose again, I would like a Buddhist system. This novel and its characters are purely fictitious.
