In Tianji Continent, Lin Yuan, the good-for-nothing son of the Lin family, was publicly humiliated by Zhao Tianhao, the young master of the Zhao family, during the clan test because he was unable to sense Tianji and was fined in the forbidden area of the family. In a desperate situation, he touched the ancient scrolls left by his mother and unexpectedly awakened the talent of "absolute logical thinking", which can analyze the nature of all things and deduce cause and effect. With this, he quickly understood "shrunk into an inch", killed the Zhao family's pursuers, and even discovered the mysterious blood characters of "Nine-Star Curse" on the murals in the forbidden area. In order to find out the truth about his mother's disappearance and revitalize the Lin family, Lin Yuan joined the outer sect of Tianji Pavilion, and went from being hostile to Su Li, a disciple of Tianji Pavilion, to solving the mystery of the mine and exploring the nine-star ruins. Every time he solved the problem, he obtained secret messages and achieved breakthroughs. Faced with the increasing pressure of the Zhao family and the Mizong Palace, Lin Yuan evolved his logical thinking into a "tianji logical chain", commanded the family's defensive battle to severely injure powerful enemies, and uncovered the truth about his mother's sacrifice to seal the rift in Guixu. In the end, he merged reason and emotion, used his own Tianji origin to recast the nine-star seal, and defeated the villain. Unexpectedly, the continent's earth veins changed, the Tianji Stone dried up, and strange cracks appeared in the sky. A greater crisis affecting the entire Tianji Continent was quietly coming!
