Modern engineer Shen Wei accidentally traveled back to the Kangxi period and became Su Qingwan, the daughter of a Jiangnan official. Faced with the dilemma of salt tax deficiency, river engineering corruption, and people suffering from hunger and cold, in the name of Su Qingwan, she used modern knowledge to resolve the dilemma: improving the sun-salting method to relieve the salt shortage, promoting sweet potatoes and corn to save the hungry, building keel waterwheels to treat floods, and creating double-entry accounting to clear the treasury.
In the court, Su Qing chatted with corrupt scholars at night, used chemistry to identify grain mixed with sand, used geometric measurements to expose the fraud of farmland, and used first aid to save the critically ill Kangxi. She rose from an unknown girl to a "talented woman who helped the world" that the emperor relied on.
The undercurrent of the nine sons' seizure of the legitimate children was turbulent, but she refused to rely on her and stayed true to her original intention; Tsarist Russia was peeping at the border, and the remnants of the three vassals were not cleared up, so she used strong ships and cannons to consolidate the territory. When Su Qingwan's modern wisdom collided with the chronic diseases of the Kangxi Dynasty, let's see how she stirred up the storm as a daughter and blazed a new path for a powerful country in the torrent of history.
