MTL - Immortal Becomes a Stay-at-home Dad After Return - ~ 549 Teacher, I have to sign up!

Life is a clash of desires, of wants, of musts…What is good?What is evil?Is one who saves his sister in place of hundreds, evil?Is another who sacrifices his sister to save hundreds, good?Life is no idealistic fairytale.Unique, it so easily gives and takes opportunities.For me? Life had taken one, and given another— two lives.This was no longer earth.On Sanctum, the ‘Wheel of Fortune’ decides how we start, but not where we go.As I woke, I knew not who I was, where I was, nor where I came from… Even my name eluded me… Yet I did not care.I knew my purpose.To find her...To find the strength to protect her...To build a reputation she would embrace, as the hero she'd always envisioned...On the 22 floating islands of the Arcane, knowledge is one’s most powerful weapon, and at the same time, greatest vulnerability. The web of lies and deception spread far in this world, some even woven and hidden by the very gods. The abyssal mysteries— those who near them get swallowed within the endless fogs that speak tales of Sanctum’s inevitable doom.For the sake of the world, I envision. This won’t do…Dearest Nina…___Dearest Joseph…********THERE WILL BE ABSOLUTELY NO HAREM IN THIS NOVEL!!I actively despise it as it slows down the story for no reason and serves NO purpose other than self insert fantasy slop.If you're here for diabolical activities that make sense, a smart MC who isn't naive for the sake of plot, where everything has meaning, leads to things without downtime and empty chapters, a story not about just an OP MC self insert fantasy, character development and morality, a mysterious world and plot twists, you've come to the right place.AUTHOR NOTE:Hey, It's Drip again. You may know me from my work on The Great Demon SystemThe first few chapters will be on earth, then it will transition into fantasy after where things will really pick up (before chapter 10). The MC will be very unique in the way he interacts and develops, things aren't always as they seem on the surface, so I hope you look forward to it :))As is common with my novels, my MC is NOT a morally ideal person, but it all has meaning so be prepared, or excited!I've been really busy with university work lately and have been cooking this novel up. I feel like it'll be something special.5 Chapters a day until around chapter 50, then I'll post daily

Thanks to your accurate instinct, our military could prevent damage in advance.”The more I struggled to be discharged, the higher my performance evaluation became.
