Chongzhen in the Late Ming Dynasty: Heroine, Who Are You?

In the late Ming Dynasty, I started with Cobalt 60. A double-travel story set at the end of the Ming Dynasty, with demons and demons inside and powerful enemies outside. Cao Qing, who traveled through time in the modern era, collided with a historical figure who traveled through time in ancient times. The imperial examination was useless, the industrial revolution, the fight against bandits and bandits, and the realization of free trade. There is no heroine or a single heroine, and I am not a virgin. If you have any last words, just say it.
