Tang San, a rare genius, lives with his alcoholic blacksmith father Tang Hao. Tang San longs for maternal love, but Tang Hao keeps his mouth shut about his wife. It was not until Tang San's twin martial spirits awakened that his father told him that only by becoming the strongest and bravest in Douluo Continent, with strong strength and heart, could he be qualified to bear the news of his mother. Tang San did not forget his father's agreement, and studied in Notting Academy and Shrek Academy successively. He met Xiao Wu, a smart and playful cute girl, Dai Mubai, a tough and cold prince of Xingluo, Ou Sike, an auxiliary spirit master who is keen on art, Zhu Zhuqing, a cold girl from a famous Xingluo family, Ma Hongjun, a simple and kind mutant spirit master, and Ning Rongrong, a little princess of Qibao Liuli Sect. These six genius teenagers with different personalities kept running in conflicts and collisions and formed the "Shrek Seven Monsters". Tang San always remembers the words of his teacher Yu Xiaogang, "There are no useless spirits, only useless spirit masters", and he perseveres in cultivating the useless spirit Blue Silver Grass, regardless of wind and rain. After a thorough investigation, he learned about the grievances between his parents and the Spirit Hall, but he never changed his original intention and overcame many difficulties with his perseverance and strength. The Shrek Seven Devils also advanced passionately in the Spirit Master Academy Competition, and eventually not only won the finals and stood at the top of Douluo Continent, but also cleared the clouds and mist, revealing the conspiracy of Bibi Dong, the first sect of the Spirit Hall, to dominate Douluo Continent.
