In the Taixu Realm, monks use their spiritual consciousness as a pen and Dao ink as ink to inscribe Dao patterns in their bodies to gain the power of heaven and earth. Everyone in the world believed that Dao patterns were given by God and could only be copied, not dismantled—until Lu Heng saw the "lines" in the dust of the Old Objects Pavilion.
Lu Heng, who was born with a "twilight level", has a weak Dao foundation, and his lifetime limit is only three Dao marks. He is destined to become an abandoned son of his family. However, there is a "string seed" sleeping in his body. Under the thirty-six layers of seals, there is the supreme inheritance of the sect that was destroyed three thousand years ago. While others were still reciting the diagrams of their predecessors, Lu Heng had disassembled thirty-six "Dao strings" and reconstructed the Dao patterns with his own "string grammar": the Hidden Breath Pattern can erase the sense of existence, the Gale Wind Pattern can travel in the wind, and the string cut can cut off the foundation of other people's Dao Patterns.
From the dilapidated attic in the Yunlu Mountains to the Ten Thousand Patterns Tower of the Taixu Taoist Alliance, Lu Heng used his shimmering body to do things that defied nature. But as the string seeds were unsealed layer by layer, he discovered that the Xian Zong three thousand years ago was not destroyed by natural disasters - the Blood Pattern Cultists, the eyes in the depths of the Dao Wen Academy, and the "door" at the end of the Gui Xu Xian Sea were all waiting for this young man with the string seeds to become a new sacrifice, or... The new string master.
This is a rhapsody written with lines, a forbidden journey about "understanding" itself.
