Uma Musume, but with Domain Expansion!

Chen Yefeng was once the “strongest of the modern era,” chasing gold medals, until an “arrow” struck his knee. Then he transmigrated. The Three Goddesses healed his legs and, while they were at it, handed him a new job.

“Go work as a trainer at Tracen Academy! You get a reward if you win, and you get a reward if you lose.”

“Seriously? Is there really such a sweet deal?”

The goddesses smiled. After all, no such deal existed. Trainers who mysteriously vanished, a shadowy figure appearing near the staff apartments at night, and Tracen Academy's survival rules for trainers.

Absolute gravity, the basement it gave rise to, and the one who taught him the horse jump was...

“Don't get it wrong. You're the challengers.”

Chen Yefeng stood on the racetrack, crossed his hands, and formed a hand seal. Turning to look at Tamamo Cross, Oguri Cap, Rice Shower, Haru Urara, and the other horse girls behind him, he proclaimed his inevitable victory! But then...

“Hey! That's my line, Trainer.”

[Domain Expansion: Infinite Void]

“It's you?”

Those eyes were unmistakable!
