Zhenguan: I Stole the Empress and Used the System to Rule the World

(Completed) (This story is entirely fictional. Please don't take it too seriously.) Lin Yu, a modern young man and history enthusiast, transmigrates by accident to the turbulent Wude era of the Tang dynasty. The moment he opens his eyes, he faces a momentous choice that could change history: steal Changsun Wugou away before she becomes Li Shimin's wife. Just as panic sets in, the Strongest Emperor System binds itself to him. Complete its missions, and he can obtain all kinds of astonishing skills and precious resources.

To win Changsun Wugou's heart, Lin Yu uses the System's Poetry Mastery skill to astound everyone at a poetry gathering and catch her attention. After that, he draws on modern knowledge granted by the System to improve farming techniques, dramatically increase grain yields, solve the people's food shortages, and win their support.

However, Lin Yu's intervention enrages Li Shimin, and the factions at court begin moving against him as well. In this perilous Tang dynasty, can Lin Yu use the System to protect his love with Changsun Wugou, establish himself amid the maelstrom of power, and ultimately conquer the realm to found a golden age of his own?
