In the tenth year of Chongzhen, the Ming Dynasty was in turmoil. In the dazzling white light of a laboratory explosion, two 21st century science and engineering youths accidentally traveled through time.
The boy's soul returned to the dragon couch in Qianqing Palace and became the last emperor Zhu Youjian; the girl landed in the Shen family courtyard in Suzhou and transformed into the orphan Shen Qingzhi who was under house arrest by the eldest brother. The two are thousands of miles apart, and they don't know each other's life or death, so they can only struggle in troubled times.
With the identity of Chongzhen, he was trapped in a desperate situation surrounded by civil wars, military divisions, post-Jin cavalry and refugee uprisings. Instead of relying on the golden fingers of the system, relying only on the vision and forbearance of modern people, he secretly trained three thousand private armies and planned them step by step. He did not seek to gain power, but only wanted to do his best to protect thousands of people in the Ming Dynasty.
Living in the south of the Yangtze River, she broke away from the confinement of the Shen family and plotted a counter-attack. She used modern knowledge to create a glass mirror and a flintlock gun, repel the Dutch fleet in the East China Sea, and build an overseas stronghold. She saw through the decay of the imperial court in the late Ming Dynasty and did not want to rely on the Mud Dynasty. She only wanted to preserve the cultural heritage of the Han family and leave a way to retreat overseas and counterattack in the future.
For four years, in the north and the south, the two returned to the same place by different routes, silently working to save the world.
In the autumn of the fourteenth year of Chongzhen, on the banks of the Jialu River in Kaifeng, Li Zicheng decided to dig up the Yellow River and flood the city. He drove his troops to personally fight for help, and she led the river convoy to the north for danger. During the siege of the rebel army, she rescued him from injury, and blurted out an ordinary modern colloquial sentence, instantly making the two recognize each other.
There is no sensational embrace, only the shock and forbearance of meeting in troubled times. From then on, two souls across time and space walked side by side, using human wisdom and knowledge of science and engineering to carve out a way for China to revive in the desperate situation of the late Ming Dynasty.
