“Your Highness, there’s something I’d really like for my birthday.”

“What is it?”

“Will you promise to listen?”

Then the man blatantly laughed.

But who would point out his arrogance – a young Northern Duke who’s not even afraid of the Emperor? He could even get a throne if he wished for it.

But it was just a sweet lover’s birthday wish.

“Alright. I swear.”

So, Juliet spoke lightly,

“Please break up with me. I don’t love you anymore.”

A fiance just for show. A succession of meaningless nights.

Now is the time to end seven years of unrequited love.

Some people transmigrate into Emperors, others become wangye.

They live in luxury; their hands covering the Heavens.

Some people transmigrate into shizuns, or sect leaders.

They would have the respect of all, their powers supernatural.

Some unlucky souls become villains, but even with their terrible reputations they would still have enough power to summon rain from the sky, maybe even manage to kill off the protagonist.

But Li Changtian, a stand up young man from a good family, who died on the battlefield protecting someone, widened his eyes.

He! Transmigrated!

Into a person everyone wanted dead, with an unabsolvable crime!

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?
