Chen Yu, an engineering master's graduate, transmigrates into the body of Suo'etu's good-for-nothing illegitimate son, and is poisoned by his elder legitimate brother from the start.
With pig fat, he makes soap to win over a consort; with a redesigned musket drill, he wins over the crown prince. Scientific formulas become his ultimate edge in the battle among the nine princes for the throne.
A grassland princess kisses him and demands compensation, his scheming childhood sweetheart breaks into his bedroom at night, and a cold, beautiful doctor wants to use him to test her poison bugs?
When the arrows of the Imperial Bodyguard force aim at his back, Chen Huaiyu finally realizes: the greatest transmigrator in the imperial court isn't him at all...
