Lin Yuan, the prince of Da Chu, was turned into a hostage of Da Qi due to the destruction of his country. In order to survive, he was forced to play the role of an arrogant villain. In fact, he secretly practiced the "Hidden Pulse Art" passed down by his family and collected information on the restoration of the country. He uses the "playing degree" mechanism (non-Goldfinger, set-type growth) to improve his strength, uses his villain identity to slap the powerful in the face, mislead the enemy, and gradually establish an intelligence network. In the process, he went from confrontation to cooperation with Su Qingzhu, a female disciple of Xuantianmen who misunderstood him, and finally revealed the truth about the destruction of the Qi Dynasty. He completed the counterattack of restoring the country in the image of a villain and became the "most legendary pretender" in the fantasy world.
