Nae Joseone Sejong-eun Eopda

A modern soul awakens in the royal court of the Joseon Dynasty, reincarnated as Grand Prince Yangnyeong, the eldest son of King Taejong. History dictates a cruel fate for this body: he is destined to be stripped of his title as Crown Prince, paving the way for his younger brother, Chungnyeong, to ascend the throne and become the legendary King Sejong. However, this new inhabitant possesses something no one else in the era holds—the complete knowledge of what the future has in store. Refusing to accept a predetermined downfall, the reincarnated prince resolves to alter the course of history entirely. Armed with foresight, he sets out to forge the prosperous, enlightened kingdom that Chungnyeong was always meant to build, intending to accomplish it long before his younger brother ever gets the chance. With unwavering ambition, he claims his own vision for the dynasty, declaring that in the Joseon he intends to rule, there will be no need for a King Sejong.
