Lin Mu, a Golden Core cultivator, awakens after sleeping for ten thousand years. Spiritual energy has become scarce in the world, and his cultivation has deteriorated, leaving him with only his resilient Golden Core body. By a twist of fate, he saves Ye Qingcheng and becomes her bodyguard. Using his abilities, he overcomes one crisis after another, refines pills to restore his cultivation, and wields the Lone Star Sword to protect those around him. He repeatedly faces challenges from various powerful families and helps Ye Qingcheng rebuild her spiritual foundation. The two eventually marry. Just as the turmoil subsides, a message from the Ye family in the capital reveals to Lin Mu that a shocking conspiracy lies behind his ten-thousand-year slumber.
