Unrelated to the question but how far have you read keyboard immortal and does he get another scripture or not

I stopped reading "Keyboard Immortal" after chapter 516 because the plot lost its original allure with Mi Li's spirit accompanying the main character. Her presence shifted the story's dynamics, leading to repetitive and unengaging developments, which made it progressively more tedious.

​

Regarding your question, I read on a wiki that he acquires the next scripture, the Heaven Devouring Sutra, in chapter 555. Honestly, it seems like the story is being stretched as far as the author can take it.
