The Demon Monarch System - Chapter 50 - Overbearing Demonic Techniques

What's it like to be wrongfully killed? Cheng Su felt she'd really hit rock bottom when she was yanked out of a building by someone who jumped. Talk about a true miscarriage of justice! But when she opened her eyes again, she found herself back in the eighties, replacing the 'culprit'? In her last life, she was clear and alone, but in this life, she had a promising, dazzling military husband, as well as a cocky and domineering third child? Ugh, spit on that! She had died with cheats, so since the husband was hers, she'd beat anyone who dared to snatch him—pummel one, annihilate two. She'd make gourmet food to sell at a stall, start a chain of restaurants, and earn the money herself. She'd have the children, flirt with her husband, and fight off any mistresses; as long as her military husband doted on her, all was good. With this cheat-code life, she wanted to eat well, drink well, gain both fame and fortune, and together with her husband, make a home anew! “This story is purely fictional.

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?

By the coast, a hundred-meter Star Gate shimmered with flowing light.Beyond the Star Gate, an army forged of steel stretched as far as the eye could see.Above the Sky Dome, squadrons of fighter jets streaked across, weaving an iron curtain.In the distant ocean, scores of aircraft carriers, destroyers, and frigates dotted the seascape, ready for action.All cannons were aimed at the figure who emerged from the Star Gate.“In the name of the Federation Command Center, I order you to stand down, or what awaits you is total war,” said the voice.“War?”Gu Jinlai took a step forward, and his form swelled against the wind, in an instant growing from less than two meters tall to a colossal Chaos Demon God thousands of kilometers high, emitting the brilliance of a white dwarf star from his being, his own gravity causing thunder and lightning, as well as tsunamis and tides within a thousand-mile radius.He looked down...At the war weapons that seemed like toys.He reached out, and a hydrogen bomb fell into his hand.Within him, the electron-degenerate star core released Helium, Helium elements expanded, and the terrifying high temperature instantly caused Deuterium and Tritium, Hydrogen's isotopes, to fuse, the energy bursting forth, forming a blazing white brilliance on the ocean's surface that was like igniting a sun.Before this sun's energy could be released, he clapped his hands together, and the dazzling white, mixed with heat in the billions of degrees, was compressed and sealed within his palms, not a fragment escaping.“I think, you should choose peace.” he suggested.

What would happen when someone from our world was suddenly reborn into the world of My Hero Academia with a Gacha System that rewards him with abilities, techniques, and skills from Jujutsu Kaisen? Grand epic fights and crazy shenanigans as he goes through the story to cause chaos and change the world to his liking.
