In this continent where martial arts is revered, Han Yuan, a gentle scumbag, appears to be a down-and-out scholar with no power, but in reality he is a slanderous master with a vicious tongue. In an accident, he obtained the ancient "Poisonous Tongue System" - as long as he accurately attacks the enemy with words, he can obtain "complaint points", which can be exchanged for training resources such as exercises, elixirs, and formations. When the bully male partner bullied civilians in the street, Han Yuan said, "Your brain and muscles have grown in reverse, your brain has been trained on your biceps." Not only did he successfully save the person, but he also accidentally awakened the system and started a counterattack by pretending to be a slap in the face. He uses his eloquent tongue to scold powerful enemies, and uses his words to distort the rules of the battlefield, making the enemies mad and crazy. Others practice by meditating, but he relies on arguing. From a humble scholar who was looked down upon to a peerless power that made everyone dare to curse three times, Han Yuan used one mouth to tear apart all those who looked down on him and embarked on the legend of the road to heaven.
