Daily Life as a Medic in an Infinite World

Sun Siming, a military doctor who had just finished his internship, suddenly found himself in a strange place. His memory was also foggy, and he could not recall his past memories. Looking at the system panel in his field of vision, Sun Siming realized that he seemed to have traveled through time into a game called "The Walking Dead"? Well, although I have some incomplete memories, as a doctor, I have to treat illnesses and save lives. No matter what, in order to save lives, I have to follow the protagonist even if there is no main mission! Use your own choices to avoid all kinds of tragedies! This is the story of a military doctor's adventure in an infinite world. But to be precise, it is a story of survival. After all, although there is a system, the rewards given are completely rubbish. Completion reward for clearing the first world "The Walking Dead: Game Edition": a set of medical kits Completion reward for clearing the second world "Train to Busan": a silenced sniper rifle (without ammunition) Reward for completing the mission of the third world "World Zombie War": randomly select a melee weapon
