Inside the room, watching the two facing off, the short-haired brown girl simply played on her phone. But the temperature in the room seemed to rise higher and higher; a flash of lightning seemed to be seen between their eyes. The blonde girl with pigtails gritted her teeth, while the long-haired girl stomped her feet. Finally, they started arguing. The short-haired girl looked at them, but they seemed to ignore her and continued arguing. She put down her phone. "Stop arguing, give me, Hui, some face." A 0.0000001-second pause. The clenching of fists and the stomping of feet only grew louder. The short-haired girl had no choice but to pick up her phone again.

One day, Song Shuhang accidentally joined a chat group for veteran chuunibyou (middle school syndrome) sufferers. The group members all had avatars of certain anime characters and talked about strange topics—Chihaya Aine: [Family, just arrived in London and assigned to the Badger House. Does anyone know how to make the Pointon potion?] Mech Warrior: [Has anyone played "Cosmic God"? Why is Gaia's stats lower than Thunderbolt's? Do I have to go to jail for a second transmigration? This is truly speechless.] Lu Mingfei: [Uh... does anyone know what the hentai world is? I have a blond guy next to me who looks a bit too strong, and three incredibly beautiful older sisters with him... huh? Holy crap! Am I the victim? Song-ge, help me!] Toyokawa Shoko: [My Maybach was hit by a Yonhap. Where is Kassel?] At first, Song Shuhang thought everyone was just having a chuunibyou moment and doing cosplay online. It wasn't until various videos and photos were uploaded to the group chat by other members that Song Shuhang realized they really seemed to be time travelers. So the question is... if they've all time-traveled, how far behind am I? Suddenly, a group of people shouted in his ear, "Sir, we are willing to go with you!"

Wu Sen's parents were brutally murdered.

The prisoner, Lin Xuan, was arrested and brought to trial, but he produced a doctor's certificate stating that he was mentally ill.

In court, Wu Sen was caught in an emotional black hole. In a fit of rage, he rushed over and tried to strangle Lin Xuan, but was pulled away by the police and kicked by Lin Xuan. His head hit the corner of the railing, and he fell into a coma.

When he awoke again, the world was quiet, and unknown sounds rang out, like the roars of wild beasts.

Man-eating zombies, monsters and alien species that humans cannot fight against.

The end of the world is coming.
