I Traveled to the Ming Dynasty and Became Emperor Chongzhen

In the 21st century, I traveled through time and became Emperor Chongzhen, the last emperor of the Ming Dynasty. Tianbeng started, and Li Zicheng directly invaded Beijing at the beginning. No, I want to turn the tide, I want to save the Ming Dynasty, I want to preserve the foundation of the Zhu family, I want to preserve the last grace of Emperor Chongzhen, and preserve the great rivers and mountains of our Han people.
