Two Male Leads, Cultivation, Geniuses, Peers, a Touch of Ensemble Cast, and a Focus on Progress Through Training

A CP is optional. Transmigrate-into-a-book stories or System stories are both fine. If there's a System, I don't want missions about winning someone over. I'd rather have cultivation or main-plot missions. If there's a CP, I hope they're both talented people of the same generation. No master-disciple romance, and not too much focus on the romance. Let it develop naturally.
