The pottery merchant traveled through time and became Tao Qian's eldest son. At the beginning, he angered his father because of the toilet paper issue. Tao Qian: Treason! You wipe your ass with a secret message! Potter: Can you blame me? Ancient times without toilet paper were so anti-human! Just when the father and son were in a panic, Tao Shang awakened the system and could get rewards as long as he changed history. Tao Qian: What kind of monster are you trying to be? Tao Shang: Dad, I will help you govern Xuzhou first, and then I will take care of Liu Bei and Cao Cao. Tao Qian: ... You should go and forget about that letter first.
