Bai Zixun, a doctor of modern biology, accidentally traveled to the ancient Liang Dynasty and became the young master of the Bai family, a wealthy businessman in the capital. He was born with the appearance of a puppy, seemingly innocent and harmless, but in fact he has eight hundred years of scientific knowledge in his head. When he first entered the capital, Bai Zixun was regarded as an embroidered pillow, and his competitors from all walks of life scorned him. However, everyone was shocked when he used modern logic to solve the eight-legged puzzle in the imperial examination room, used chemical principles to create stunning fireworks at the royal banquet, and used biological knowledge to solve the enemy's poison attack on the battlefield. Faced with the difficulties faced by the young master of the aristocratic family, Bai Zixun always maintained a harmless smile, but crushed his opponents time and time again at critical moments. He used modern knowledge to change ancient times, used his simple appearance to confuse his enemies, and eventually grew from a despised "little pretty boy" to a supreme wizard with great power.
