Lin Yichen, a modern archaeological team member, travels back to the late Ming Dynasty with an ancient sword, which coincides with the accession of Emperor Chongzhen to the throne. The Eunuch Party and the Donglin Party are fighting to the death, and the Ming Dynasty is in turmoil.
Relying on modern knowledge and ancestral Tai Chi, he traveled between the court and the rivers and lakes, improving firearms and reorganizing internal affairs in an effort to prolong the life of this dying empire.

When his beloved was bleeding on the battlefield, his hair turned gray overnight, and he finally grasped the sword in his hand, vowing to create a bright future!
