In ancient times, Earth was known as the “Ancestral Star,” the birthplace of cultivation civilization across the Myriad Worlds. All races paid homage, and immortals and gods lived alongside one another.
Then came the cataclysm known as the “Shattering of the Heavenly Dao.” Fearing that the Ancestral Star’s power might threaten their rule, the mighty beings of the Upper Realm joined forces to establish the “Spirit-Severing Heaven-Sealing Grand Formation,” sealing away every law of cultivation on the Ancestral Star. The cultivation legacy was severed, and the spiritual veins withered.
But humanity’s desire to seek the Dao endured. Building on what remained of the incomplete legacy, people created a simplified form of “martial arts.” Martial arts could temper only the body and vital energy, not sense the spiritual energy of heaven and earth, making them a “false path.”
As for Lin Yuan, when he was on the verge of death in a car accident, the “ancestral blood” within him awakened, granting him the legacy of the "True Explanation of the Defiant Dao",
a forbidden cultivation art capable of “reversing all techniques.”
The inner force, true qi, astral energy, and other powers cultivated by martial artists are, in essence, degraded forms of spiritual energy. Lin Yuan can use the "True Explanation of the Defiant Dao" to “reverse cultivate” them into pure spiritual energy for cultivation.
