The Upper World Took Away My Talent, and I Stole It and Became an Emperor.

The protagonist (Lin Xuan) is a chaotic Dao body + Heavenly Spiritual Root that comes once in ten thousand years from the Qingyun Sect in the lower realm. The sect's grand ceremony triggers visions of heaven and earth, and is cross-border locked by the elders of the "Tianyan Dao Sect" in the upper realm. The Taoist body and spiritual roots are forcibly taken away and fed to the Holy Son in the upper realm. The protagonist becomes a useless person. When he is about to die, he awakens to seize the Heavenly Dao system/original Heaven-devouring bloodline.
