I Cultivated Immortality for a Hundred Thousand Years, and Returned Invincible

Lin Qingxuan proves himself an emperor in another world, then returns to Earth just in time for the college entrance exams.

To honor his mother's dying wish, he plans to have a little fun and become the top scorer in the exams.

With only two months left until the exams, is there still time to study?

This year's exam questions are said to be at an epic level of difficulty?

Sorry, that's child's play for me. I'm a genius.

Cultivation? I have no interest in cultivating. I'm already an Immortal Emperor, so why would I need to train?
