Get Ready to Feel the Fists of the New Boss

With a second chance at life, I'll knock out the front teeth of anyone who mouths off to me.

Get ready to feel the new boss's fists.

I've got a System, but it's unreliable and transmigrated me to the wrong time. I've got a divine weapon, too, but there's a five-in-six chance it'll kill me.

In that case, I might as well gamble my life from the start.
