Era background: The fictional Cao Wei (non-official history, integrated into the system of cultivating immortals). The world is divided into three major forces: Cao Wei, Shu Han, and Soochow. There are also groups of cultivators such as "Zongs", "Aristocratic Families", and "Loose Cultivators". The levels of cultivating immortals are divided into: Qi Entrainment, Foundation Building, Jindan, Nascent Soul, Transformation, Void Refining, Fusion, Mahayana, and Tribulation Overcoming. Each major realm is divided into four small realms: initial, middle, late, and peak.
- The relationship between cultivating immortals and the secular world: All major forces need "immortal cultivators" to enhance their combat power. The governor (the protagonist's assistant, named "Xiao Jingyuan") is in charge of "Yunzhou" on the border of Cao Wei. Without the support of strong immortal cultivators, he has been suppressed by hostile forces ("Shuiyun Sect" of Soochow and "Fengtian Valley" of Shu Han) for a long time. He is also squeezed out by the aristocratic families in the DPRK and needs to urgently break the situation.
- Protagonist skill correlation: Protagonist Mi Galen's "Barber Clerk" skills (hairstyling, customer communication, account management, tool maintenance, detail observation) are transformed into immortality/secular abilities——
- Hair design: By combing the "texture direction" of the hair, you can understand the "trajectory of spiritual energy" and create an exclusive "hair air entrainment technique";
