One Piece: Don't Worry, I'm a Doctor - Chapter 84: Lies…

Humanity was living peacefully on Earth for millions and millions of years until the day unknown monsters from beyond space invaded them.

When humans were about to disappear, some people with abilities came out to the light and shared their knowledge and powers with the world, and together, they managed to push back the invaders during a terrible war that had lasted for years.

This war had created many orphans, and among them, Kye had lost everything, even his parents. And the only thing he received from their death was a pale-looking necklace.

However, once the necklace finally activated, a system was given to him, and his life changed completely.

The system gave him quests to do, and Kye complied. He was getting stronger every time he achieved them, until the day it gave him a weird quest.

[You have one day to kill the one who had sinned. If you do not kill, you will die.]

But now with hypnosis.

(Apocalypse Farming, Sweet Pet 1V1) As soon as she opened her eyes, Su Shu found herself reborn two months before the Apocalypse. Before her rebirth, a certain man watched over her and protected her for three years, almost going as far as dragging her home to swallow her whole. After her rebirth, not only did she have to raise her adorable genius niece, but she also had to take care of a wolfish husband. This Apocalypse was a bit different! The pitiful her from her previous life now not only had a heaven-defying space, but also blood-related family, and on top of that, the indulgent spoiling of Tang Dashao, who sprinkled dog food without restraint. Su Shu thought, even if the heavens required her to reset and start over once again, it wouldn't matter. She would just meet Buddha, kill Buddha; meet a ghost, kill a ghost!

Because her appearance was not breathtaking, the Emperor breaks off their engagement and bestows her instead to the bloodthirsty, ruthless, and cold-blooded Second Prince (Wang Ye).

On her wedding night comes endless humiliation, the genuine Princess Consort becoming a deserted women. A foolish woman before rebirth, she no longer expects his love. In this world, she must possess enough talent to awe those around her, carrying herself with composure and articulating with beautiful diction, override above the nine night.
