The Legend of the Protagonist of the Apocalyptic Red Alert

The protagonist is looking for the final way out of the two worlds One is a Red Alert world that once had highly developed technology and strong military power. There, humans used their wisdom to create amazing buildings and powerful military units. In order to compete for resources and hegemony, various camps competed fiercely on the virtual battlefield. The war was raging and the smoke was filled. The whole world was immersed in an atmosphere that seemed prosperous but was full of dangers. The other one is the ordinary, real world full of vitality and fireworks. People live a nine-to-five life, the streets and alleys are filled with laughter, children play in the park, and couples stroll on the streets. Everything is so harmonious and beautiful. However, a sudden change, like a nightmare coming, broke the peace. An unknown virus spreads rapidly, turning the living into the walking dead, cities reduced to ruins, civilization nearly collapsed, and the world plunged into apocalyptic darkness and despair.
