She transmigrated as a disgraced concubine confined to the cold palace, with a white silk noose around her neck from the start. Her five-year-old son saved her life with a line spoken in his sleep. He had a special ability: dreaming. Sometimes his dreams foretold the future, sometimes they revisited the past, and they were about seventy percent accurate. After dreaming, he always came down with a fever, and the weaker his body, the deeper his dreams. He knew nothing of politics or schemes, but he knew that "when red things break, people die" and "hands turn red because of poison." The disgraced concubine in the cold palace interpreted his dream talk and turned it into action. From then on, she used her son's dreams to turn the imperial harem upside down.
