[Western fantasy online game, infrastructure explosion, fourth natural disaster, technology vs magic, rigorous data, no female protagonist] Three days before the launch of the national online game "Under the God's Throne", Ye Xuan arrived in the Saint Ourria continent ahead of schedule, but traveled through time and became the lowest level wanderer NPC. He thought his future was bleak, but accidentally activated the most powerful war factory system. The sound of gunfire rang out for the first time in another world, the shield was torn, the level was meaningless, and Chaofan fell in the storm of metal. Since then, steel has become the main color of the world. As for swords and magic, the only thing left is the romantic epic that has been sung.
