Having returned home in the evening and feeling fully satisfied after a series of purchases, Li Zheng sat at the desk and took out the competition paper he had worked on at noon to start studying with the answer explanations.
But he stopped quite soon.
Damn it.
He couldn't understand it even with the answer key.
Having no other choice, he temporarily gave up on that exam paper and turned instead to open a basic textbook for the chemistry competition—"Inorganic Chemistry."
This blue-covered "Inorganic Chemistry" was truly a classic among classics; even the school library had it.
Essentially, it was a university textbook, but because of competitions, it was used even more by high school students.
Li Zheng didn't ponder further; his primary task for today was to complete the "Demon Challenge" and first get his chemistry score up to 200.
He then opened the textbook and started from scratch.
