Dragon Ball: I, Son Gohan, Get Stronger by Doing Push-Ups

Transmigrated into the Dragon Ball world as Son Gohan, I obtained a training system right from the start. As long as I casually do push-ups, my strength increases. Moreover, the stronger Gohan becomes, the more his combat power grows with each push-up. (The system's enhancement is just an addition; it doesn't affect Gohan's own training to become stronger!)

"Ding! Congratulations, master, for doing one push-up, combat power +1!"

"Ding! Congratulations, master, for doing one push-up in the Hyperbolic Time Chamber, combat power +10!"

"Ding! Congratulations, master, for taking one step, combat power +1!"

"Ding! Congratulations, master, for doing one push-up, combat power +10!"

......

Beerus: "Damn it! How does this Son Gohan train? He's even stronger than me!"

Son Gohan: "It's nothing really, I just do push-ups every day!"
