The title of the work is inspired by Vedic theorem, without any hint.
"The Combination of Two Roots": When Lin Yan wrote the last equal sign on the competition paper, he never thought that he would bump into Jiang Yi - the transfer student who was using a compass to draw the function image of Vedic's theorem on the draft paper. The tip of the pen was poking through the page with such force, as if he was nailing a secret into the formula.
As a key "problem-solving machine" of the province, Lin Yan was accustomed to measuring the world with logic, until this young man who always skipped classes and went to the rooftop burst in with a bright sunshine: he could solve super-class problems with wild answers, and said that Vedic theorem is "two roots looking for a way home." The title page of the yellowed notebook in his arms was printed with the same strange symbols as Lin Yan's father's old papers.
During the days when they were forced to partner up, they were two opposing sides of the equation: Lin Yan's rigor collided with Jiang Yi's jumping-off, but when solving problems again and again, they discovered that each other's ideas could always fit together perfectly to form a complete solution. When the academic grievances of their parents came to light along with the notes in their notes, and when the value of the "sum of two roots" contained the salvation of two generations, they were shocked to realize that some of the answers had been written in the same equation since birth.
"You know?" On the eve of the finals, Jiang Yi put headphones into Lin Yan's ears, and the white noise mixed with the sound of his heartbeat, "The most cruel thing about Vedic Theorem is that it allows you to meet the root that must be him."
