The ancient great power used words to convey the truth, wrote the creation of the world, and destroyed the book to destroy the world. Three thousand years ago, the "Book Burning Disaster" left the Heavenly Way incomplete and spiritual energy disordered. Ancient books became the key to mending the sky. Restorers used ink as a medium to mend the ancient books. This was to mend the Heavenly Way, but it also hid a life-and-death crisis. A single wrong thought would cause a "Word Disaster" and be counterattacked by the rules.
Lin Xiuwen, a modern ancient book restorer who traveled through time, possesses the magical power of the "Omniscient Eye" and can see the causal cracks and contaminated ink stains hidden in ancient books, but at the cost of forgetting his memory. He originally wanted to survive in a low profile by relying on his skills, but due to an illegal filling-in of characters, he was caught by Su Wanmo, the female headmistress of Wenyuan Pavilion, and was involved in the core game between the court and the sect.
The Wenyuan Pavilion factions are in conflict, and the four major sects each have their own agenda. The secret organization "The Silent Ones" vows to burn the world's books, claiming that "the only way to show civilization and mercy is to destroy the classics." Under the guidance of the sloppy Taoist Zhao Chongyang, Lin Xiuwen gradually discovered the shocking truth: repairing ancient books is not mending the sky, but consuming the origin of civilization. The paradox of "repair is destruction" puts him in a desperate situation.
From a low-level craftsman to a bookkeeper, and then to a game-breaker who questions the rules, Lin Xiuwen brings his omniscient eyes to the underground palace, explores ruins, and searches for forbidden ancient books. In the whirlpool of power and the test of life and death, he seeks a third way between repair and destruction. He not only has to fight against the world-destroying conspiracy of the "restoring saint" Wen Renjing and protect the people he cherishes, but he also has to uncover the dusty secrets of the book burning disaster and rebuild a new way of heaven that does not rely on ancient books and has its own right way.
Wherever the ink marks fall, the Tao appears; in the remaining scrolls, the universe is hidden. This journey of using the pen as the blade and ink to patch the sky will eventually rewrite the fate of the book world.
