If You Are in Naruto, Take Master Lu with You Wherever You Go

I was a street writer, coding in the middle of the night, but what I never expected was that I would fall asleep because I stayed up too late, drooling on my notebook, and get electrocuted to death. The more important thing is that the world he traveled through turned out to be the legendary Five Villages Fighting. But fortunately, as a time traveler who died of electrocution, Tetsu Kamiya finally got a piece of software on his computer as his golden finger. "What do you mean by rogue software that has to be tightly bound to you even though you have traveled to another world?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
