I Defend the Mortal World with Martial Arts

After a brief spell of darkened skies, the spiritual qi revival arrived as promised. Ancient evil gods awoke. Wild beasts in the mountains and forests gained sentience and became monsters. Cultists of heretical faiths returned. Vengeful spirits and ghosts rebuilt Fengdu. Outland superhumans watched with covetous eyes. Donghua, an ancient empire, would face the harshest trial of all. At this time of peril, Ye Wu, who had been living in seclusion in a mountain village, stepped back into the world. He forged an indomitable martial spirit from the warmth of everyday life. He tempered his body through a hundred battles into the mightiest martial physique. He gathered surging blood and qi from the spirit of Donghua. When a group of young people gathered atop a mountain and made a solemn vow, they vowed that the lights of human life would shine as brightly as the stars, and that they would defend the mortal realm for a thousand years with mortal bodies. The world needs heroes. (The protagonist is invincible once he leaves seclusion, standing at the pinnacle of martial arts in the mortal world.)
