The Chongzhen Emperor did not hang himself. After moving south, he established the Southern Ming Technological Court. By chance, he acquired a complete copy of The Exploitation of the Works of Nature and embarked on a comeback built around the idea of saving the nation through science and technology.

In the end, however, he discovers that saving the realm in a physical sense is far easier than saving its rotten institutions and people’s hearts.
