Zhang Yufan, the "young master uncle" who is the next master of Ziji Qingxu Temple, was ordered by his master to go down the mountain to join the world in order to prove the truth through tribulations. He entered the History Department of Capital University as the top scorer in the college entrance examination. In the dormitory, he discovered that his three roommates also had extraordinary origins: Lei Zhen, the young master of the Jiuxiao Thunder Sect, Yun Xuanji, the young master of the Yunji Lingxu Pavilion, and Fu Chen, the next Celestial Master of the Xuanyue Celestial Master's Mansion. Four Taoist heirs with special skills formed the "First Paranormal Investigation Team of Capital University" under the guise of "historical research". Starting from solving the legend of the "Senior in Red" on campus, they gradually got involved in a series of urban supernatural incidents and fought against the villain organization "Ten Thousand Souls Hall" that used modern technology to combine ancient magic. As the investigation deepened, they discovered that the real purpose of the "Ten Thousand Souls Palace" was to break the seal of the "End of Law Tribulation" that was jointly suppressed by the four major sects, in an attempt to return the world to chaos. In the end, the four brothers joined forces, mobilized the power of their respective sects, and staged an ultimate showdown in the modern city to defend the right path of the world and protect the spiritual veins of heaven and earth.
