The Wonders of Creation: Do I Have to Score 720 on the Gaokao Too?

[Infinite flow + no CP + unconventional rules horror + an exceptionally kind protagonist]

[Note: This really is infinite flow. Readers are welcome to put themselves in the characters' shoes as they tackle each challenge. There is no single path to victory, no one right answer. Come along for the ride: if you found yourself in this world, what would you choose?]

Cheng Pu, a rich second-generation kid, gave up his comfortable life to become an overworked high school teacher for the sake of his dream. For that same dream, he even went to teach in a remote area. As expected, he ended up trapped in a rule-filled supernatural space.

The space: If you don't score 720, you're all dead!

Cheng Pu: 720 points... That's not so bad.

His friends: ?

His friends: Do I have to get 720 on the college entrance exam too?

The space: [a garbled character]

His friends: I'm jumping, folks. I'm out.

Cheng Pu: No! (grabbing his friends' hands tightly) I won't let you die! Don't give up! o(╥﹏╥)o

(No harem, no CP, told mainly from the perspective of a single male protagonist. There are several female leads, but no romantic tension. Rules horror? Rules and the mind's inner landscape!)
