As a veteran fast traveler with more than ten years of service, Zhao Shen planned to wash his hands in a golden basin and live his life freely after completing his last mission. But at the moment when Zhao Shen submitted his resignation to the main system, he, who was known as the system's biological son, was thrown into the flesh-culture world by the main system without any warning for a final resignation experience. Main System: Zhao Shen, this system has always been deeply concerned about your physical and mental problems. In view of the fact that you have developed good psychological quality at work, this system has carefully prepared ten worlds for you to strengthen your body. From now on, physical and mental health is no longer a dream. #Militarycadet'splaything##biology teacher's teaching# Zhao Shen: ... It's very unhealthy to look at these worlds.
