Almost everyone knows that the greatest hero of the late Sui Dynasty was Li Yuanba, but very few know that the greatest genius of the late Sui Dynasty was Zhang Yizhen. This is undoubtedly related to the hero complex of the Chinese people. Our Chinese nation has always had heroic figures revered throughout the ages, while traitors are remembered for their infamy. It’s easy for someone like Zhang Yizhen, a greedy and lustful fellow, to be overshadowed in the chaotic world. Zhang Yizhen was not a hero. Although he was highly skilled in medicine, he never did anything without expecting something in return. If you wanted him to treat you, you either had to have money or be beautiful. Most of the rich people he treated gave him money, and most of the women he cured were exceptionally attractive. Such anecdotes about this unscrupulous doctor are too embarrassing to be recorded in official history. Zhang Yizhen met a tragic end. Despite his advanced martial arts skills, he first drank poisoned wine from Emperor Yang of Sui and then was shot by a thousand Imperial Guards. The cause of this unfortunate event was his selfless act of saving the life of the Empress, who was in a difficult childbirth. He felt extremely wronged by this outcome. He had done a good deed by saving the lives of the mother and child, only to end up with such a fate. Truly, an eternal injustice. Emperor Yang didn’t feel any remorse, saying, “Damn it! You dared to touch my woman. You’re lucky I’m only killing you!” Scientific research in later generations proved that the energy of resentment can transcend time and space, leading to an overwhelming accumulation of grievances. Therefore, Comrade Zhang Yizhen became one of the millions who traversed through time and space, luckily enough.
