The hostess crossed because she wrote down a formula of mass and energy and then went to parallel space. In the real world, Lin's father got it, his first love went abroad, and a woman's career was underestimated. In the depressed environment of Lin, I thought of the formula in my old house.

In order to let some old Woods find their way home, Lin thought of the mass and energy formula that Lao Lin taught himself when he was a child, and the first crossing was opened like this.

The woman who studied philosophy thought about life when she was about to graduate from college. She found that being a teacher according to her previous ideas would make life impossible. Then she thought of her old father, who loved mathematics, and Pei Zhi, a mathematical male god who secretly loved her since childhood. She decided to transfer to graduate school of mathematics.

However, as a liberal arts student, she gave up the study of mathematical olympiad very early, and being admitted to the best graduate student of mathematics department in China within one year is tantamount to dreaming.

At this time, fate opened a window. As long as the hostess writes down the relativistic mass formula E = MC 2, she can travel to another parallel world, and her thoughts are attached to herself in the fifth grade of primary school. In the parallel world, in the fifth grade, she brought about qualitative changes in college students' thoughts, personalities and grades.

The point is that at least when she was a child, she was persuaded by her old father and learned all kinds of knowledge about mathematicians. She can stand out in the primary school Olympic competition and participate in the Olympic summer camp. Here, she also successfully met Pei Zhi, a fifth-grade student, and was able to overcome the difficulties in the mathematical world with the male gods.

Whenever she gains courage or enlightenment in the parallel world, she will be forcibly sent back to the original world by the god of fate. When I came back, I didn't finish my time in the original world for a second. Because of the time spent in the parallel world to improve the level of mathematics, the female host in the original world can show amazing mathematical talent, solve problems, participate in modeling competitions, and attract the attention of universities. Everything that was out of reach a day ago, after a crossing, "comes naturally."
