After dying suddenly from overwork, A Cang, the king of rolling in the emergency department, transmigrated into the notorious "mute good-for-nothing" in the savage beast world! Luckily, her mother is the hot-tempered tribe leader, and her two older brothers are combat ceiling powerhouses, protecting her like a priceless treasure. She originally wanted to go with the flow and lie flat like a salted fish for a lifetime, but unexpectedly, the royal city high priest secretly played dirty tricks, cutting off water and poisoning them, forcing the Gray Wolf tribe to sacrifice A Cang's family! Seeing her family still protecting her behind them despite being covered in scars, A Cang stops pretending! Using wood ash for gastric lavage, bone-setting techniques to cure paralysis, purifying antibiotics to resolve plagues, and engaging in infrastructure to cut off divine power and financial paths! Let's see how the max-level medical student wields a scalpel in the beast world, bringing her top-tier protective family, and slaughtering her way back to the Beast King all the way.
