The End of the World: Awakening of the Metal Superpower System at the Beginning

[Apocalypse + Rebirth + Zombies + Decisive Killing + Not the Holy Mother] The apocalypse is coming, zombies are besieging the city, and natural disasters continue. Lu Yang, who had been struggling to survive for two and a half years, activated the killing system and gained metal powers 10 minutes before he was reborn in the apocalypse. As long as you keep killing zombies, zombies, mutated plants and even warriors and awakened ones, you can get a lot of experience points. These experience points can improve your ability level and can also be exchanged for various skills. While others were hiding at home, afraid to go out, or becoming food for zombies, Lu Yang relied on his superpowers to kill all the enemies in his way. In this life, he will reject all moral kidnappings and make those who oppress and betray him pay the price with blood!
