The Artifact-World's Succubus, Apparently! (Thanks to "Dark Star Emperor" for the generous tip!)

"Come on, come on, line up and take turns cosplaying as speed bumps on the highway! No more than five at a time; we'll split you into groups of five and take turns."

After pocketing nearly 300,000 yuan in tuition fees in one go, Su Yuan immediately demonstrated his excellent customer service by gathering the first group, including Jin Hao, beside the highway.

"Big Brother Su Yuan, may I ask if there's some secret to what you and Big Sister Wu Ziying did on the highway earlier?"

Jin Hao asked, nervous but hopeful.

If possible, they wanted to learn the trick to the Big-Rig Training Method once and for all.

That way, they wouldn't have to waste money every time they had a body-tempering class.

Su Yuan smiled faintly.

"Secrets can't be taught. You have to figure them out for yourselves. Once you do, you'll be ready to graduate."

"All right, get on the highway."

As soon as he finished speaking, he shoved Jin Hao and the other four out onto the road.

As the Big-Rig Spirit Vehicles came hurtling toward them, the five Special Class students were sent flying in a succession of graceful arcs.

Standing beside the highway, Su Yuan used the computational power of a Qi Cultivator to rapidly calculate where each airborne student would land, then made sure the Hundred-Ton Kings struck precisely the body parts that needed strengthening.

One person would've been easy enough, but calculating the collision trajectories of all five while also building rapport with the Hundred-Ton Kings pushed Su Yuan's brainpower almost to its limit.

By the time the first group finished training, Su Yuan's brain was throbbing with exhaustion.

But to make sure his customers had a great time cosplaying as speed bumps, Su Yuan immediately hurried over to greet them.
