When his daughter is born, his spiritual roots evolve, causing strange phenomena to appear in the heavens and on earth! The day he takes a concubine, he even gets an unparalleled cultivation technique! In public, he acts crazy and foolish, seeming harmless to both people and animals.

Then the apocalyptic calamity arrives, and Lu Changqing takes one step forward, his might suppressing the ages. The Lu descendants are collectively stunned: Our father and ancestor, who does nothing but eat and wait to die, is actually a hidden Martial Dao Emperor?!
