Cultivating Between Classes: I Quietly Ascend to Immortality at an Elite School

Looking for a Modern Urban Campus Cultivation Novel

From the start, the male lead goes abroad to find his girlfriend, with Li Zongsheng's song lyrics “Crossing Oceans to See You” playing in the background. They break up, and he comes back, where he meets a woman who transmigrated from ancient times. He follows her in cultivating to become an immortal. I read it several years ago, and it was already complete then.
