Sign-In at the Cold Palace: Raising the Prince to Conquer All Nations

Modern young man Ye Ming wakes up after a sudden transmigration, trapped in the Great Xuan Dynasty as a lowly eunuch tasked with tasting poisons in the desolate Cold Palace. Resigned to a life of obscurity behind forbidden walls, his fortune takes a turn when he unexpectedly unlocks a daily check-in system—each new dawn grants him supreme martial arts manuals and priceless elixirs. Deep within the frigid compound, he encounters a neglected young prince, ignored by the entire court, and instantly recognizes the latent emperor's spark hidden in the boy's eyes. Armed with modern knowledge and foresight, Ye Ming secretly mentors the prince within the lonely palace grounds, cultivating his mind and character step by step. As deadly conspiracies brew among concubines and ruthless schemes unfold in the imperial court, he relies on sharp wit and ever-growing martial prowess to steer through every peril. More than a decade passes. Enemy hordes thunder toward the borders, and the Great Xuan Dynasty stands on the verge of ruin. Now enthroned as the young emperor, the once-forgotten prince kneels before the Cold Palace gates with all his ministers and generals, and speaks the words that shake the realm: "Little eunuch, we can hide no longer—it is time for you to act."
