An Emergency Doctor’s Life as a Mercenary

I'm serious about saving lives, a professional when it comes to protecting people, and I do enjoy taking the spoils...

Lu Fei, an emergency room doctor, is forced to transmigrate to a small town in a parallel-universe America. He gains a rescue System and, by a twist of fate, becomes a licensed mercenary.

A real man has to cut people open often to save them from danger, and regularly get into fights and killings, wielding thunderous force with a compassionate heart!
