In the comic, Tianjiu? Qin Shi? Fox Demon (may be added later), because there is too little sugar, we can't eat enough, so we turn to be cooks. Without further ado, let's start with the introduction:
World 1: Hong Lian died on her way to the Qin Kingdom in exchange for her brother in her last life, but she was killed unexpectedly. Once she was reborn, she returned to Han Fei Sanghai to study and returned to the country. She remembered that her brother died in the Qin Kingdom, but the specific reason was unknown. This time, her first task was to become stronger and protect her brother! And... Was that the man in black clothes and white hair that she saw before she died...?
Intention: Fulfillment of unresolved wishes
