Chen Lifeng, the retired former chief translator of the country, was publicly humiliated in English by his son Chen Guodong's family. He shocked everyone with his profound English knowledge. Later, Chen Guodong asked for help because of work, and Chen Lifeng asked him to admit his mistake and help him, but he attracted his old rival "Vulture" to threaten his family. In order to protect his family and fulfill his national mission, Chen Lifeng returned to the world and took his reformed son to the negotiation battlefield, vowing to defeat his opponents.
