Zhou Li sent off Zhao Yi with a bitter smile, and then returned to his writing desk. When he looked carefully at the calculations left behind, he immediately became serious.
Ten minutes.
Half an hour.
One hour…
Zhou Li scrutinized the calculation sheets for almost an hour and a half, and in between, he rubbed his scalp so hard that he had lost quite a bit of thin hair. His heart was filling with more and more despair.
"I... can't understand...?"
Zhou Li had not expected to encounter such a situation. The steps in the draft paper were clearly written, all carefully deduced by Zhao Yi himself.
Normally, the deduction process in the draft should be logically clear. That means, you should be able to understand it from beginning to end.
Now Zhou Li found himself stuck in a mental blank, as if he were a student who couldn't understand complex mathematical content. He could understand every line of text on the draft paper, but he didn't understand how it was deduced.
