Chess Player: Observer of the Strange World

Xunran traveled to a world eroded by strangeness. Here, it is impossible for people to fight against the strangeness. The only way to survive is to contract the strangeness. But if you want a contract, you must meet strict conditions: the pollution degree is lower than 80%, and the purification progress is higher than 30%. A little carelessness can lead to disaster. What's even more desperate is that every midnight, the entire world freezes for one minute. In this minute, all the weirdos will reveal their true identities, and only Xunran can move freely. [Danger value: E+ | Contamination level: 62% | Purification progress: 0%] [Rating: E+ (danger·avoidance recommended)] While others were trembling in the fixed grid, Xunran was staring at the panel with the corners of her mouth raised: "This E+-level 'Bandage Painter' is very suitable to be my first chess piece." The weirdness rating ranges from F- to ZSSS (Ghosts, Gods and Masters), and progresses step by step. The source of pollution hides murderous intent, and Xunran's observer panel has just awakened... "Since heaven and earth are disks, and all things are sons -" "Then I will play this game of chess." It's a game of dancing on the edge of a knife. It also belongs to those who play chess - the road to becoming a super god.
