After Donating a Kidney, I Was Dumped. From Then On, I Quit Being a Nice Guy

[No goody-two-shoes heroine + No doormat + Decisive and ruthless + Always gets even + System]

Chen Zheng was an honest, straightforward man. For the sake of true love, he generously donated one of his kidneys to the girl he adored.

His pure and virtuous crush, untouched by the mire around her, thanked him for the kidney by giving him a bright green hat!

Furious, Chen Zheng awakened a System.

The System’s starting ability: Curse!

[Ding! Curse target locked: Zhang Peng.

Zhang Peng is tall and mighty, an absolute beast!

Curse Zhang Peng with explosive impotence, turning him into Zhang Peng’s eunuch. Reward the Host with 100 merit points.]

After awakening the System, Chen Zheng becomes an agent of justice. He stops being an honest pushover. Anyone who bullies others gets struck dead by a bolt of lightning.

Faced with the girl he once adored, he curses her with kidney failure.

When someone walks their dog without a leash, he curses them with rabies and parvovirus.

Faced with village tyrants, he curses them to be struck by lightning, so the whole family can die together!

Faced with school bullies, he curses them to be smitten by heaven’s thunderbolts, ending their brief, wicked lives.

If someone rubs him the wrong way, he curses them to die as “a feast for ten thousand worms.”

Countries around the world are stunned. Why are supernatural events happening one after another?

Huh! Why does Chen Zheng show up in all these supernatural events?

System upgrade: Healing ability. (Can cure every disease.)

Chen Zheng becomes a miracle doctor, stunning the world once again...
