A crossover anime female trainer, starting with her as a mount

Shen Bai transmigrates to a crossover anime world and becomes the female protagonist's trainer.
By capturing and "training" the female protagonist through a physical link, a win-win situation can be achieved.
Yuki Suo: Brother, you should have arranged human training for me a long time ago.
Kato Megumi: Shiro, I also want to become the center of attention, hurry up and train me!
Miko Yotsuya: Mystic Eyes of Death Perception, I've evolved Mystic Eyes of Death Perception. Haku, don't move, let me handle this.
Hellish Blizzard: Training? Hmph, I'm not infatuated with you, I just want to catch up with my sister. Come behind me.
While others capture spirits, Shen Bai captures female protagonists. When Shen Bai is enjoying the company of three thousand women a day, he ascends to immortality in broad daylight, even annihilating the Great Dao itself.
