Reversing the Mortal Dust

On the Zhiming Continent, spiritual cultivation is revered, while body cultivation is scorned. Mortals without spiritual roots are born to be trampled and enslaved by spiritual cultivators. A hundred years ago, body cultivators defied the heavens but were ultimately crushed by the heavenly dao, becoming a laughingstock. The orphan Lin Mingyuan, bullied and with his family slaughtered, digs up a fragment of the ancient 'Dahuang Mingyuan Jue' in despair. Without spiritual roots, he turns his body into spirit; without a dantian, his flesh and blood become steel. From then on, the youth abandons immortal cultivation for body refinement, defying the heavenly dao with his mortal frame, shattering celestial venerables with his fists! — Description from novelcodex.org
