Qin Zheng, a genius doctor of chemistry, once traveled through time and became a dying refugee during the Zhenguan period of the Tang Dynasty. Facing the "life-saving" salt blocks distributed by the government and containing excessive impurities comparable to poison, and seeing the miserable situation of people around him suffering from poisoning, his professionalism was intolerable.
A pot of crudely purified snow-white salt shocked the world, but it also led to a fatal disaster - the steel knife of "Private official salt, kill without mercy" was already on the neck!
In the thin line between life and death, Qin Zheng came to his senses in a hurry: "This is not salt, but an antidote elixir!"
At this moment, the county magistrate, who was foaming at the mouth, suddenly fell to the ground...
From then on, an alternative "Expert from outside the country" was forced to appear. With his left hand, he relies on the guise of "alchemy and medicine" to survive, dealing with officialdom games and various forces; with his right hand, he quietly spreads the technology tree of the time traveler, from purifying salt, refining glass, improving gunpowder, to building water conservancy, creating new materials... Step by step, he turns advanced chemical knowledge into the "philosopher's stone" of this era.
Let's take a look at how a doctor from a humble family used science as a sword and wisdom as a shield in the magnificent Tang Dynasty to stir up troubles, subvert the court, play in the shopping malls, and finally become a "technical prince" that no one dares to mess with!
