In the seventh year of the end of Blue Star, outside the safe zone is a wasteland where pollution beasts are rampant, and inside the safe zone are gangs that eat people. Lin Ye was kicked out of the medicine shop and was blamed for the death of the gang leader's only son. He had no food, was in debt, and was hunted down. Even his survival was a problem. But he has a way in his hand that others can't understand - God rewards those who work hard. Treating diseases can improve medical skills, practicing boxing can improve martial arts, and rescuing people can improve physical fitness. The more tired you are, the stronger you will be, and the harder you fight, the more fierce you will be. Others relied on their background to save their lives, but he relied on hard work to change his destiny. Today you call him a waste, but tomorrow he can save a life on the spot, and the day after tomorrow he can decide life or death with a single shot. After that, secret realms, auctions, martial arts families, cults, and foreign royal families all have to kneel down to watch him take off.
