MTL - The Era of Rebirth: Supermarket Space is Easy To Get Rich - Chapter 167 came back

Betrayed by those he empowered. Slain at the peak of his reign. Reborn into a world unworthy of him.Tian Mo was once a supreme cultivator, a dark sovereign who ruled with absolute might and terrifying intellect. After a million years of conquest, his closest allies turned on him, stripping him of everything. But fate offered no rest. Reincarnated into modern-day Earth, he awakens in a weak mortal body—yet his memories, ambition, and ruthlessness remain untouched.In this strange new world of technology and fragile peace, Tian Mo finds new prey. With the Primordial Chaos Demonic Evil Physique and the forbidden Divine Sins Emperor Technique, he begins building his empire from the shadows. He manipulates the system, devours the corrupt, and topples the powerful—not out of justice, but vengeance... and the endless hunger for power.There are no heroes in this tale. Only a monster reborn—and the world that will burn beneath his feet.

One day, a Tower appeared, and with it a proclamation by God that Humanity is to be judged for becoming too corrupt.Regression…It’s an ability so fraudulent that it doesn’t require any detailed explanation.Yes, I also agree that it is a fraudulent ability, but…Isn’t it too much to regress due to just a slightest injury…?

I, a HIKKI-NEET, suddenly reincarnated in another world as a prince, and was immediately deemed the weakest ever, with my life already in a pinch after being abandoned as a baby, being stared down by a huge beast!?

However, I could only use one kind of magic. It was close, but I was able to avoid a “dead end” in my first few days of being born using that magic.

Anyways, I just want to live a lazy shut-in life as an adopted noble with my one all-purpose magic, but…?

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?
