The questions were as deep as the ocean when he delved in.
Time was but a passer-by.
Li Zheng, who had entered his "Passion for Chemistry" state, unknowingly set a new record for completing new questions in one sitting.
Two hours.
One entire book's worth of foundational Chemistry questions, and an entire book of advanced questions.
He had completed all of them.
At this moment, he had less than an hour of energy left.
Li Zheng felt enriched, yet empty.
"90 hours passed just like that?" he thought.
"It sure isn't enough."
Fortunately, his Chemistry score comforted him.

Li Zheng felt invigorated once again.
At this level, he should have no problem passing the college entrance exams.
His once weakest subject was now his absolute advantage.
The time he spent studying this weekend hadn't been wasted!
