Xiao Liu, the heir to an ancestral anti-cancer prescription, sells the medicine at nearly cost price to save lives, but the price of 2,500 yuan is questioned by the patients' families. Under the temptation of low-priced medicines from pharmaceutical companies, family members collectively reported the case, resulting in Xiao Liu being imprisoned and his grandfather dying in hatred. Xiao Liu was killed in revenge ten years later. After accidentally being reborn and returning to the day he was reported, Xiao Liu was determined to fight back, destroying the medicines and selling plasters instead to avoid traps, repeatedly thwarting the plots of his family and the pharmaceutical company. He refused the profit temptation of pharmaceutical companies and chose to cooperate with the National Research Institute to lower drug prices. He not only avenged his past life, but also finally made life-saving drugs available to the public. In the game of human nature and the battle of life and death, he completed redemption.
