The protagonist is a fun-loving troublemaker who, thanks to sheer luck, gets a sky screen System. It can play all kinds of TV shows and movies, and can even broadcast fake videos based on what the protagonist imagines.

Captain America stares in utter confusion at a video of himself fighting Japanese soldiers on the Chinese front alongside Yan Shuangying and Sadako. Tony Stark gets a massive headache watching Morgan throw the timeline into utter chaos just to meet him. Yue Buqun and Lin Pingzhi repeatedly bang their heads against the wall, all because the screen says you can master the Evil-Warding Swordplay without castrating yourself...

Superman watches enviously as the version of himself who grew up in China spends every day doing good deeds for ordinary people. In short, parallel worlds, endless possibilities...
