Chronicles of the Firmament: I Built Rockets in the Ming Dynasty

Lin Qiong, a genius aerospace engineer from the twenty-first century, unexpectedly transmigrates to the first year of the Chongzhen era in the Ming dynasty. The Little Ice Age is bringing disaster after disaster, famine is spreading, the Later Jin cavalry beyond the frontier is watching menacingly, and the Ming dynasty is on the verge of collapse.

Facing a nightmare from the start, Lin Qiong has no System or supernatural abilities, only a mind full of knowledge far ahead of its time. He begins by improving farm tools and making "fertilizer" to relieve the famine, then builds telescopes and upgrades cannons to defend the borders. At last, he turns his gaze toward the depths of space. He intends to launch the first sounding rocket in this era and use an overwhelming technological advantage to win an entirely different future for Chinese civilization.

This is a passionate story about the stars and the earth, technology and human nature, and how individual choices can determine the survival of a civilization.
