Reincarnated as the Baron's son: My Infinite Card Upgrade System - Chapter 12: A knight’s trust

A character with extreme difficulty and the worst performance, Baek Yu-Seol was considered tr*sh in the game because he couldn’t use magic in a fantasy world where everyone else could.

However…

[Due to the wrong ending, 90% of Aether World has been destroyed.] [Please reach the ‘True Ending.’]

Suddenly, those words echoed in my mind before I was transmigrated to the Aether World.

[You can use the skill ‘Flash’.]

“Why did I possess this character?”

Flash was the only magic skill I was given.

Surviving in Stella Academy where many genius mages ran rampant, I became the notorious Flash Mage.

Keeley, a simple plain Jane, hits the jackpot. [No, she did not win the lottery!] At least that's what she thinks when she marries the most eligible bachelor in New York City: Aaron, a wealthy cold-hearted heartthrob and Tycoon.

In a world filled with Ability users, Demons and Extraterrestrials, Damion Darkblade finds himself born there without any parents to care for him, or an Ability of his own.This rare deficiency causes him to get bullied by his peers always, and his life became a living hell in the academy.The bullying gets so consistent and terrible to the point where he almost loses his life one day.However, with the interference of fate and a stroke of luck, he is recognized by someone with unprecedented power, and Damion's quest for revenge and ultimate glory blooms.[Congratulations Host!][You have received the Dragon God's Legacy][You have unlocked the Ability: Shadow]

What’s not to love about my new life after transmigrating into a Pet-centered world?
There are mighty creatures that come in all shapes and sizes. They can either be cuddly companions, helpers in your daily life, daring scouts or strong fighters. Or all of the above. Not bad, huh?

I have a family, but the fact is completely overshadowed by my younger sister. She thoroughly hates my guts, and she makes sure that I know this. Every. Single. Day.
Did I mention that she’s disgustingly talented while I am a bottom feeder? A terribly handsome one at that.

I have free rein to run the family business on my own. A small and quaint Pet Store. It should have been great if not for the fact that the previous owner of this body was born with ZERO affinity to handle Astral Pets…

It wouldn’t be a proper transmigration without a gimmick or a system to pave my road to greatness, don’t you think? I have one, but I don’t know if I would be better off without it…
