Hello, Did You Call for Rescue?

[Includes a delusion-fueled protagonist, nontraditional Fourth Disaster elements, and extremely chuuni, over-the-top plotlines] [The protagonist is a chaotic-good player] A strange app appeared on the computer. A pitch-black icon, its name a string of garbled text. No matter how many times it was uninstalled, it would reappear in the same place the next day. Thinking, "Virus or not, I'll fight you to the death," Shi Qi clicked it with a blank face, ready to go down with it. Huh? You damn thing, you're actually a game?! Reluctantly, Shi Qi entered the garbled game. A fog that covered the entire map, teleportation anchors that had to be unlocked one by one, an incredibly realistic physics engine... and a bunch of NPCs who looked terrified whenever they saw him. Even the starting village had a difficulty level enough to break anyone's spirit. The unreasonable mechanics at every turn made it seem like a game created by a mental patient to take revenge on society. And Shi Qi was the only unfortunate soul playing it. The only player in this world. So fear became reverence, despair turned into hope, broken fragments gradually became whole, and a stranger brought new life to the world. Fog covered the world, an unknown System invaded Blue Star, and humanity lost control over its own lives, forced into isolated captivity. Only those who obeyed orders and cleared the game could obtain the supplies they needed to survive. Anyone who resisted was killed without mercy. Despair and suffering formed the nest, while darkness and bloodshed piled up into walls. Until the airtight enclosure was violently torn apart, light shone through the cracks, and the world began to welcome a new dawn. Someone knocked on the thick wall and asked curiously, amid a crowd of stunned faces: "Hello, did you call for a rescue?" Theme: Even when trapped in despair, believe in the dawn
