Tian Guan Xue Yuan

To resist invasions from other worlds, the Heavenly Great Sage founded Tianguan Academy. Every year, the Academy would recruit new students—but in the end, only nine could become the official Heavenly Officers. Gu Tian, a young soccer player, accidentally awakened his hidden power while saving someone on the field. Invited by his senior Xia Zhi, he boarded Subway Line 36 to Tianguan Academy. With the world’s finest teachers, strict assessments, and a brutal elimination system, the Academy pushes its students to the limit. By a stroke of fortune, Gu Tian became the 81st student to pass the entrance trial. Under the guidance of celestial masters, he studied spells and divine decrees, honed his combat skills against powerful rivals, and strode forward step by step toward the ultimate goal of becoming one of the Nines.
