One Piece: Human God - Chapter 34: Daily Life: Shanks vs Buggy/ Revolutionary Army

As soon as he crossed over, Su Mu came to another world.

In this world, there are warriors, qi refiners, and all kinds of terrifying ghosts and monsters!

A good rebirth simulator turned into a death simulator because it was too dangerous.

For him, death is not the end, but the beginning.

In the simulation again and again, thousands of demons have been derived!

The flesh and blood are put into the pot, divided and eaten, turning into a bloody skeleton.

He died in a wrongful battle, his body did not rot, and he turned into a dry zombie.

Introduce thunder into the body, turn extreme yin into yang, and transform into a fierce reggae.

Devouring demon souls, suffocating the sky, turning into an undead ghost car.

Some people become immortals.

There are also people who die into demons!

He mocked the omegaverse. Now he’s living it—with a baby on the way.Souta Tachibana was just your average, overworked office drone—until his BL-obsessed coworker introduced him to a trashy omegaverse romance novel. Curious (and a little horrified), Souta read it for laughs. But then he died in an accident.Now, he wakes up in the body of Lucien d’Armoire, a minor noble in the empire of Aetheria. No plot relevance. No destined lovers. Just a quiet, boring life as a background beta.Until one morning, he throws up into a chamber pot… and his doctor says something unthinkable:“Baron d’Armoire, you’re pregnant.”Which is impossible.Because he's male.And straight!And because Betas can’t get pregnant.…Right?Except Lucien is no Beta. He’s a rare male Omega. Apparently, during one reckless, drunken night, Lucien slept with an Alpha. Now he's pregnant, confused, and definitely not ready to be a father. To make matters worse—he doesn’t even know who the father is.

The Infinite Survival System suddenly appeared on Planet Blue. Those who are chosen are forced to survive in dungeons.

The Survivors can continue to grow stronger if they survive the dungeon missions. However, just one failure and it would be their deaths.

Every Survivor gets a talent. Some talents can boost the Survivor’s agility, and some enhances their luck, while Zhou Chen’s talent was Passive Plunderer. It allows him to plunder the passive skills of the monsters he hunts.

With that talent, Zhou Chen slowly gathers a powerful list of passive skills.
