One Piece: Don't Worry, I'm a Doctor - Chapter 55 - : Too Timid!

Shao Qing’s only regret in life is that she blindly fell in love with a worthless man. She gave up everything for him, but in exchange was run over by his conniving mistress when she was close to her delivery date. Fortunately, Heaven left her a way. Crimson rain fell from the sky, the end of the world arrived, she resurrected in the morgue and gave birth to a little monster. Turning into a half human, half zombie freak; her son neither human, nor monster; they have no other choice but to rely on zombies’ crystal nuclei to develop their special abilities and continue living. This debt, she’ll definitely repay that cheating couple!

A replica of Marquis Kieran Vale, the son of the Marchioness of Vale, who she deemed a failure. That was all she was. No, she was now referred to as “he.” At least until she met Claude Del Ihar.

Ryan «Quicksave» Romano is an eccentric adventurer with a strange power: he can create a save-point in time and redo his life whenever he dies. Arriving in New Rome, the glitzy capital of sin of a rebuilding Europe, he finds the city torn between mega-corporations, sponsored heroes, superpowered criminals, and true monsters. It’s a time of chaos, where potions can grant the power to rule the world and dangers lurk everywhere.

Mediocrity is the normal state of most people, and some of them can’t even reach the normal state~ A young man from a small town, ugly and inferior, disliked by relatives and friends, mediocre grades…

All these changes started with a beam of light going to the university train, and the boy was bound to the high-quality male god system.

The days are getting more and more hopeful, and the system is really fragrant:

As long as you learn, you can modify your own bugs;

As long as you do good deeds, you can get corresponding banknote rewards;

As long as you are praised, you can get relevant talent blessings;

…

This, it’s hard not to love, okay!
