Fake Son-In-Law: from Papermaker to Emperor

As soon as Li Yu opened his eyes, he became a nameless and nameless person traveling through the wilderness. In order to survive, he was forced to pretend to be the secret son-in-law of Shen Mansion. He thought he was just an abandoned son used by the family to block the selection of concubines, but unexpectedly, his papermaking skills turned him from a useless person in the cold courtyard to a key figure that neither Shen nor Su could despise. He made white paper, opened trade routes, established the name of "unknown layman", and used glass mirrors, kaleidoscopes, reading glasses and fairy music boxes to stir up the circle of powerful people in the capital. But the more valuable the technology, the more dangerous people are. The fifth prince forced him to give the birthday gift "Destiny Dragon Instrument". After a miracle at the birthday banquet, he was targeted by the prince, intercepted in the East Palace that night, and became a craftsman's slave in a golden cage. After being humiliated, Li Yu finally understood: without his own power, no matter how powerful his technique is, it is just a knife in the hands of others. There was a fire in the workshop, and he faked his death to escape and went south to the rivers and lakes. From then on, he no longer just wanted to make money and escape, but to establish his own order bit by bit among killer organizations, copycats, trade routes, military industry and the dark web. Many years later, an old man in the capital was implicated by a trap set up by the East Palace. Instead of escaping, he put on the mask of a "greedy craftsman" and voluntarily returned to the imperial capital. This time, he wanted to save people and settle accounts. From a fake son-in-law to an unknown layman, from a craftsman slave in the East Palace to a chess player in the south, from private revenge to the reconstruction of the world - when the magic bow alerted the border troops, old evidence from the previous dynasty surfaced, and the most filthy old sins of the Jin family's imperial power were finally torn apart. This man who was once regarded as an outcast by a wealthy family will eventually use technology, wealth, intelligence, military power and popular support to overthrow the old imperial power and reshape a new world.
