Ai Qinglan's mathematical attainments were not low to begin with. Jiyin Valley's field of study—the roots of bloodlines—was also at the molecular level, the very bottom layer of life. Therefore, her mathematical ability could fully compare with the elites of Burning Gold Valley, who were likewise highly skilled in this field. Myriad Dharma Sect cultivators used mathematical thought to recreate natural evolution and the propagation of living beings—for example, Turing's After Tomorrow's Will and Hand of the Common People's Beast Mechanism—and she had dabbled in such things as well.
Back in Divine Capital, it was precisely this foundation that had allowed her to help Wang Qi and the others complete the countermeasure to the God Plague Curse before the final moment arrived.
Even ordinary Core Formation Cultivators of the Myriad Dharma Sect might not measure up to her.
Of course, having reached this point, Ai Qinglan basically would not delve any deeper into mathematics. After all, it was not her primary field.
Yet even Ai Qinglan, at this level, had spent several days finishing the book Wang Qi had given her, Algebraic Topology—From Beginner to Giving Up.
And the first thing she did after finishing it was point at the back cover and ask Chen Feng, "Little Feng, what does this sentence mean?"
Chen Feng froze. He had copied a copy of that book as well, but had only read a quarter of it, and had gotten many of the exercises wrong. He looked at the line Ai Qinglan had indicated. It read: "Although this book was written by the author at a certain friend's request for that friend's wife, the author must still remind said friend: matters between husband and wife should be handled by yourselves. Do not drag friends into it to add some spice. End of book."
