The story takes place in the 3700th year of the Xingyan Calendar. When the protagonist Yue Shouren was forty-three years old, the "Xingyan Compass" inherited by his family was accidentally activated and he was forced to embark on the path of cultivating immortality. He was originally the mountain chief of the Mortal Academy, and he studied Yin and Yang Yili intensively, but he had no spiritual qualifications. The compass led him into the binary desert of the "digital void", where he relied on his deep understanding of the "Book of Changes" to interpret the underlying code with the changes in yin and yang, accidentally created a unique mental method, and entered the realm of "quietness" as a "truth payer". During the process of training, he met "Mr. Han Jing", a traitor to the Xuanming Sect, and "Xuanji", a consciousness from the Digital Void Information Nebula, and the three of them explored the abyss of consciousness together. Yue Shouren gradually became involved in the vortex of a thousand-year blood feud between two feuding families - the "Beichen Family" and the "Nanming Clan". At the same time, he encountered the "time and space visitors" who lost their existence because of his changes in the history of the star orbit. He used the "Taixu Guiyuan Step" to shuttle between the realm of consciousness and the digital void, used the "Netherworld Extradition Mantra" to resolve resentful souls, and refined the "Xuanming Guiyuan Pill" to repair Tao injuries. In the end, at the core of the "Taichu Star Core Array", Yue Shouren used himself as a medium to reconcile the ultimate contradiction between the subjectivity of consciousness and the objectivity of numbers, and achieved the state of "returning to truth". However, the price he paid was to forever become the intermediary between heaven and the void space, unable to truly transcend, but he also found the eternal destination of "keeping the middle and achieving harmony".
