Smart Prince Returns as Fool to Conquer the World

Meng Yi, the heir to the Northern Prince's throne, possesses early wisdom but unexpectedly gains a chance to communicate with the future. Upon achieving fame and success, he voluntarily sacrifices his intelligence. Ten years later, he returns as a fool. On his return day, a family crisis erupts: his father is falsely accused of treason and the princely mansion is raided. In the crisis, he wakes up with modern technology, slaughtering his way to save his mother and repel the enemy. Later, he escapes to the border with his family, narrowly surviving an ambush thanks to modern weapons. During a rainy night when they are separated, he protects his fiancée and exposes a spy nearby. His second uncle betrays them, and the Emperor orders his execution. In this critical moment, his father arrives with his forces. Meng Yi forces the Emperor to surrender with a modern army, leaving the Emperor terrified and ultimately overthrown.
