Emperor's Substitute

Modern office worker Li Ren transmigrates as the Emperor's substitute of Great Qian, immediately caught in a power struggle between the Empress Dowager and the Grand Preceptor while facing the threat of assassination by the real emperor. To survive, he leverages modern wisdom and decisive actions to win the Empress Dowager's loyalty, gain the Empress's affection, eliminate threats to his secret identity, and dismantle the Grand Preceptor's faction. Confronting the northern frontier's coup attempt, he launches a strong counterattack, builds red barbarian cannons, establishes the Divine Machine Army, relieves famine, and opens examinations to stabilize domestic affairs. Finally, leading the army personally, he shatters the northern coalition, unifies the grasslands, and steers the Great Qian out of internal and external crises toward rejuvenation, transforming from a substitute into the true ruler of the world.
