After seven-year-old Li Ya regained her memories of her past life, the first thing she did was not to fight for favor, but to climb over the wall and leave home with a box of failed potions. She originally thought she could survive alone with alchemy, but she met the fallen uncle Huo Chen in a blizzard carrying a broken sword on his back. One refused to be treated as a child, and the other did not dare to accept any more companions. The two embarked on a journey with a thirty-day contract. From the blue fire in the deserted village, the underground auction to the black tide in the north, they gradually discovered that the research left by Li Ya's mother, Huo Chen's defeat twelve years ago, and the memory disaster sweeping the continent all pointed to the same ground controlled by the powerful. The so-called omnipotence never means that one person can do everything, but that every ordinary person has the position to change the outcome.
