My Ex Just Returned from Another World and Became My Stepsister

Li Changan transmigrates to a high-martial urban world, breaks the body's limiter, ignores growth restrictions, and becomes infinitely stronger!

Three hundred push-ups add one kilogram of strength. Thirty thousand add a hundred kilograms. What about more?

What about weighted push-ups? Training on the sun under its immense gravity?

Breathing techniques increase one's vital energy. What happens when the limit is removed?

A thousand sword draws earn proficiency. What about ten million?

And so, after transmigrating as a high school student, he begins training like crazy!

Then one day, his dad opens the door with Li Changan's ex-girlfriend.

Dad: "Changan, this is your new stepsister, Su Tian!"

Li Changan's face stiffens.

What do you do when your ex becomes your stepsister? Asking online, it's pretty urgent!

My name is Su Tian. I just returned from another world, only to find that my ex-boyfriend has become my stepbrother. I'm doomed!

But this ex-boyfriend seems a little... off?

One day, Su Tian watches Li Changan doing push-ups with a mountain on his back.

She silently opens her camera.

"Big brother, you wouldn't want anyone to find out, would you?"
