MTL - World of Immortality - ~ Prologue Please euthanize me

The eve of her sister's wedding, an accident happened, the responsibility her sister abandoned, should she bear it? She's not a professional scapegoat!“Um, it's my sister who wronged you, it has nothing to do with me.”“So, is there a problem with making you, her younger sister, repay the debt?”Faced with the man's dominance, May Morgan was on the verge of tears without shedding any.“But, we haven't had a chance to get to know each other yet!”“Then let's start getting to know each other now!”

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Lin Fan acquired the Sign-in System that led him on the path of the life of a god-level nouveau riche.

This is a story of the flesh pushing everything.

In the Great Ye Dynasty, darkness descends, full of evil spirits and ghosts, killing invisible.

In the face of demons and evils, ordinary people can only shiver, curl up in the corner, and wait for their lives to come to an end.

Jiang Dao came through, carrying a martial arts modification system, and any martial arts can be modified infinitely as long as he glances at it.

The mad magic stick method, the eagle claw iron cloth shirt, the poisonous sand palm, the violent ape magic… are all revised to the realm of a thousand years later.

Facing the evil spirits, Jiang Dao had a burly body, muscles all over his body, and his eyes were like electricity.

“Evil spirits? Who said martial arts can’t kill evil spirits?”
