The so-called Heavenly Book has spirits, either like Dragon Sparrow with just a spirituality and not a life. If it was a life, Zhao Changhe now felt there was an eighty percent chance it was the blind girl. The phrase "I'll kill you first after unsealing" sounded much like a menacing threat.
Zhao Changhe was, of course, harboring a lot of resentment toward the blind girl who inexplicably dragged him into this world. If you can't beat them, couldn't you vex them from another angle?
If it really was her, she probably had a very important purpose, and such vexation mostly had to be endured.
Moreover, Zhao Changhe didn't quite believe that the Heavenly Book unsealed itself because of "severe humiliation"... Some things couldn't just happen from potential alone; not understanding math doesn't change from humiliation, does it? If these words were just an excuse from the blind girl, perhaps smearing this stuff might actually be useful.
