One Piece: Pirate King? I just want to kill all of you - Chapter 31: You Are the True Heroes!

As a boss with space plant abilities in the apocalypse, Lu Yao once traveled to the future, became the director of a nursery school that was about to close down, and became a rare animal human on the verge of extinction.
The food she made at random can cure the genetic disease of the cubs in the welfare home. She punched the cubs’ scum fathers and scum mothers, and kicked the remarried families who abandoned the cubs.
It is such a good kindergarten successor dean, who is attracted by that single cool imperial marshal!
Since then, the barrage in the live broadcast room has become:
Imperial Citizen A: Dean A, I really want to marry.
A certain big black dragon: Shut up! This is your marshal’s wife!
CP: Dean Lu Yao, who is extremely protective of short-sightedness and loves cubs, X the imperial marshal Helanjia who loves Shang Yunxi more than cubs
Brief: There are no bad cubs, only bad big ones.

Long Yu, the number one killer on Earth, after dying, takes rebirth in this new world in an aristocratic family of martial artists but faces rejection because he is unable to practice martial arts.

Even in the frail body of a newborn, Arilyn is rewarded with attributes, points, and power simply for stubborn hard work. Yet not everything is as bright as it seems. Legends walk the land, and the Blight Lords are hell-bent on resurrecting the Old God.None of this should have mattered to him, living on the fringe of the empire—until strange rumblings rise from the heart of the Candor Mountains.What to Expect: • [Reincarnation, but the MC does not retain any memory of his past in the beginning.]• [Slice of Life, Crafting, Spellcrafting, Training, Slow burn, Weak to Strong, and silly things] • [LitRPG elements, Detailed Magic system, Greek/Roman Empire-esque settings]• [Magic Academy, Eventually]• [Beast Companion?] • [No harem]

What?
Are you a soldier, will the tank drift?
You are a master, can you give birth to dragons and tigers?
You are a superman, can you call the wind thunder?
Excuse me, I am not targeting anyone, everyone in my eyes, it is rubbish!
