Time Travel: Cannon Fodder Survival

Once in time, Tan Yu changed from a miserable college student with no hope of finding a job in an unpopular major in the 21st century to the cannon fodder in the novel "His Royal Highness the Prince's Beloved Concubine" that he read a few days ago. She has a seriously ill mother, a father who died young, a young brother and cannon fodder. Others had systems and cheats to pass through books, but as soon as she passed through, the system threatened her with death if she didn't climb to a higher place. After saying this, the system was permanently offline! For the sake of the original owner and his own life, Tan Yu decided to cure his mother's illness first. As a result, when she went out to buy medicine, she met the cruel second prince who was going to a palace banquet. In the original book, she was directly killed because she accidentally looked at the people in the second prince's carriage from the window on the roadside! This time, she will never look up!
