In the world of cultivation, Canglan Realm, young Chen Yuan awakened the "Martial Soul System of All Realms", but deliberately showed "0 soul power" during the soul test to pretend to be a waste. His martial spirit can connect to the "fictional martial arts universe" in all the worlds. He can summon the "Sky-Splitting Halberd" martial spirit to sweep away bandits, and he can also use the "Shadow Eye" martial spirit to expose conspiracies. On the surface, he was ridiculed by his family as "trash", but in fact, under the guidance of the system, he traveled through the martial arts and fantasy worlds to collect martial spirit fragments. When he used modern talk shows to make the old Jianghu people spit tea at the Jianghu Restaurant, he secretly learned the "Beggar Clan"'s "Broken Bowl Beating Dog Technique"; at the Immortal Cultivation Auction, he pretended to be a money fan and held up placards, but in fact, he used the "Treasure Appraisal Eye" martial spirit to pick up the heaven-level magic weapon "Spirit-Swallowing Gourd". As the martial arts level soared, Chen Yuan counterattacked from a hunted "waste" to an "irregular" giant across the martial arts and immortal sects. While using nonsensical operations to break the villain's defense (such as using the "Lion's Roar Kung Fu" to shout out Internet hot words to shatter the opponent's Taoist heart), Chen Yuan also revealed the secret of the Canglan world that was suppressed by the laws of the world. In the end, he stepped on countless "face-slapping copies" and became the funny legend of "the co-owner of the world".
