Lin Jingyun, a modern doctor, was electrocuted and his soul passed through the poor students of the Daqing Dynasty. When he opened his eyes, he saw a leaky hut, a crying neighbor sister, a clan uncle collecting debts, and soon the fateful college examination. With knowledge spanning thousands of years, he hid his secrets in the imperial examinations, turned stones into gold in the business world, and set off thunderous reforms in the court. However, the flame birthmark on his left shoulder never ceases to burn, and the unjust case of King Zhenbei sixteen years ago remains with him. Three volumes of counterattacks in the Han family, Shanghai and Chaotang, and five love relationships with beauty, confidant, and comrade-in-arms. Let's see how he uses modern wisdom as a sword and the hearts of the people as a shield. In the whirlpool of power and emotion, he reveals his life experience, avenges his father's injustice, and reshapes the empire. This is a counterattack of knowledge against fate, and a heartfelt answer to the times.
