The Primordial Sword Demon

As a generation's Demon Lord lay dying, he personally sealed his son's dantian and also sealed his own treasured sword, the Heaven-Burning Demon Sword, within Demon Dragon Mountain.

Sixteen years later, the young Nie Tian has his dantian sealed. When he breaks the seal, he unexpectedly awakens the Heaven-Burning Demon Sword, sealed in Demon Dragon Mountain for sixteen years. This draws the attention of an unknown, powerful faction, who come to seize the sword. His entire village is wiped out, and a boundless fury ignites in Nie Tian's heart. Sword in hand, he slays gods when they stand in his way and kills Buddhas when they block his path. In that moment, the sky is stained with blood, the world trembles, and mountains crumble...

From then on, a generation's Sword Demon rampages across the world. Whoever stands in his way will be killed; whoever tries to stop him will be slain.
