When the light of the Sanxingdui bronze sacred tree swallowed history teacher Lin Xuan, he never imagined he would become the greatest variable in the Primordial World. After his soul transmigrated to the Primordial World following the Witch-Demon Tribulation, he bound himself to a damaged "Myriad Phenomena Deduction System" and discovered that the immortals here fought without regard for the rules, until he used contour maps to defeat disciples of the Western Teachings, purified the waters of the River of Forgetfulness with chemical equations, and unraveled the chaotic inner demons with Gödel's theorem.
To escape the Two Sages of the West and their relentless "Deliverance from the Sea of Suffering," he was forced to navigate the chessboard of the Primordial World: helping humanity fight famine with hybrid rice, battling alongside an Asura princess against the Eight Legions of Heavenly Dragons, and joining Yunxiao of the Jie Sect to perform the Quantum Yellow River Formation. Modern knowledge became his only weapon, but it also aroused the Heavenly Dao's wariness. As the golden lotuses of salvation cast by Jieyin and Zhunti shrouded the Primordial World, and the bronze sacred tree opened its world-ending eye outside the Zixiao Palace, Lin Xuan finally saw the truth: the so-called Investiture Tribulation was nothing more than a formatting program for rebooting Guixu.
With seven heaven-defying keys in hand and the Primordial World on the brink of collapse behind him, his enemies were Hunyuan Saints, and his trump card was high school physics, chemistry, and mathematics. At the end of the countdown, he had to teach the gods and demons of the myriad heavens the ultimate theorem for the survival of civilization in a history lesson, because Guixu's ultimate vulnerability was written right into the lesson plans passed down through the unbroken flame of the Human Sect.
