Yue Lingyu's hand gripped the tissue tightly as he sobbed and said to Yue Xin, "Sister, can you pour me a glass of water?"
Yue Xin nodded and got up to pour water. She remembered that the water her brother poured for her was warm every time, so she also poured a glass of warm water for Yue Lingyu.
Yue Lingchen did not wait for Yue Lingyu to finish crying. Instead, he simply announced the rules of the second round. "The rules of the second round are very simple. Whoever gives the correct answer first will win. However, let me remind you that the second round does not involve ordinary addition, subtraction, multiplication, and division. It doesn't include the differential equation of the elementary function solution. Yan Ye, do you know anything about this?"
Yan Ye was not surprised by the term that Yue Lingchen mentioned. It was obvious that he had learned it before.
"I do."
