My Roommate Is the Future Manifest Sage.

The protagonist travels back to Shirai's university dormitory and becomes the fifth person in 406 who is not mentioned in the original book. He knows the general plot of the original book, but does not try to seize Shirai's opportunity. 406 Is a renovated six-bed room in the old dormitory with a five-person dormitory. The original book only focused on Shi Lai and three roommates. Lu Jianwei belonged to the bed that was not photographed by the camera. He is bound to the "reward system" and often goes overseas to deal with the remnants of gods and demons, servants of demons, exotic evil gods, ruins of old gods and other hidden plots that were rarely developed in the early stages of the original book.
