The Immortal Realm's once-in-a-thousand-years Grand Heavenly Rules Examination is approaching, and only those who pass can be promoted to immortal positions. Lin Qingxuan, once a prodigious young genius in the Immortal Realm, became a laughingstock after an accident three years ago left his immortal power stagnant. To preserve the dilapidated library his master left behind, he is forced to take the examination, using his original mortal-world exam techniques to counter immortal arts. Facing the cold stares of the immortals and navigating the cracks in the rules, he sets out to prove the value of knowledge once again. From being forced to sit the exam to assembling a team, he ultimately uses his wisdom to break through the examination's deadlock and opens up a new path to advancement in the Immortal Realm.
