The End of Martial Arts Begins with Becoming a Traitor

In the ancient world of martial arts, all people respected martial arts. A powerful warrior could split mountains and rocks, break down buildings and walls. However, in this world where martial arts flourished, a zombie crisis broke out. "Can you promise me that you won't turn into a zombie after the end of the world?!" Zhang Yu looked helplessly at his master who had turned into a zombie. The master was originally a powerful warrior, but now that he has turned into a zombie, he is even more powerful. He has become the zombie king of one side and brought disaster to the other. The seven sons of Yuehua worked together to kill the Corpse King Wuyazi, but Zhang Yu was infected by the Corpse King's corpse poison and was about to die. But he obtained the [Doomsday Martial God] system. In order to continue to live, to become a Martial God, and truly transcend the apocalypse, Zhang Yu had no choice but to act cruelly and become a "devil" traitor. On that day, the Seven Yuehua Sons killed the Corpse King Wuyazi in order to save the common people and defend the Dao from demons. However, Zhang Yu, the last of the Seven Yuehua Sons, was poisoned by corpse poison and turned into a demon. He killed the eldest sister among the Seven Yuehua Sons and escaped. Zhang Yu became a street rat in an instant. Everyone shouted to beat him, and everyone in the world punished him. He was a shameful traitor to humanity and a traitor to his master. But who knows that he will eventually become the God of War...
