Chen Ke, a doctor of modern materials science, opened his eyes and became a prisoner of war in troubled times and was about to be buried alive. He used his chemical knowledge to detonate the enemy's gunpowder depot and rescued thousands of prisoners, but unexpectedly met Su Ying, a former princess disguised as a slave girl. One of the two wanted to survive, the other wanted to restore the country, so they were forced to join forces to escape. Chen Ke made gunpowder, practiced military skills, and broke down city gates. Zhou Hu was convinced and Zhao Wujiu was thrown into the urn, stepping on the bones of a wealthy family with every step he took. When Su Ying discovered that Chen Ke's philosophy of governing the country transcended the times, her obsession with restoring the country began to waver - and the real world has never been a dynasty of one person.
