A Commoner in the Zhenguan Era: I Rely on the System to Secure My Place in the Tang Dynasty

In the third year of the Zhenguan era, early in Li Shimin's reign, famine strikes, government is corrupt, the treasury is empty, and the Turks threaten the borders. The protagonist is an ordinary modern wage earner who transmigrates to this era. He has no heaven-defying intelligence, no photographic memory, and no habit of showing off or acting arrogant. He understands human nature, knows when to yield, and knows how to survive, climbing step by step from the bottom as a tenant farmer.
