Sinopsis English

Xiao Changze, the eldest son of the Great Yan Kingdom, was supposed to be crowned Prince, but he was persecuted by Concubine Qi and became demented. His mother, Noble Consort Jiang, was also slandered by Noble Consort Qi for her kindness and weakness, and was sentenced to death for committing treason. In order to eliminate the root and branch of the Qi Guifei sent the first assassin to murder Xiao Changze, but by mistake, the twenty-first century engineers traveled in his body. Xiao Changze, who is no longer stupid, decides to take revenge for his own body. He utilized his status as a senior engineer to bring advanced technology to the country of Dayan, recovered the lost land, and built the city into a prosperous and stable one. He eventually executed Princess Qi and her two sons, and forced his way to the palace with his own two concubines to make his father abdicate.
