F-Rank from the Start, and My New Female Instructor Is My Ex

Third-degree disability, cultivation completely lost, awakened an F-grade useless spirit root.

This was the grim medical report for Su Qing, the former Myriad Demons Supreme, after he returned to Earth.

To stay alive, all he wanted was to spend the rest of his life as a slacker at Star High Martial University.

But on the first day of school, a beautiful new S-rank specially appointed instructor stepped up to the podium.

Her gaze was cold enough to freeze a galaxy, and the riding crop in her hand looked exactly like the divine weapon that had once broken his immortal bones.

Su Qing panicked. She was the senior sister and ex-girlfriend he'd betrayed so cruelly!

Worse still, the System announced: He had to stay within three meters of the female instructor for thirty minutes to unlock his sealed, max-level cultivation!

Su Qing: "Heaven's Will, are you messing with me? You're sending me to my death!"

So while the whole world expected the F-grade good-for-nothing to be tortured to death by the icy instructor, Su Qing stood outside her office every day, begging to "cuddle," to the astonishment of the entire school.

Until one day, demons from another world descended, and the Ice Empress was gravely wounded, coughing up blood.

The good-for-nothing whom the whole school had written off silently picked up a broken sword from the ground and split the firmament with a single strike.
