MTL - Urban Young Fairy - Chapter 40 Library encounter

After his parents died, Alex Roth had a plan: become a wizard. Through hard work, he was accepted into the world’s greatest university of wizardry—but fate had another plan.

On his eighteenth, he is marked as one of his kingdom’s five Heroes, chosen to fight the land’s great enemy. But his brand is 'The Fool', worst of the marks.

Rather than die or serve the other Heroes like Fools in the past, he packs up his little sister, his childhood friend and her cerberus, then flees for the university in hope of refuge, magic and to unravel the truth about his land’s evil.

There’s one small problem: The Mark tries to ruin magic while enhancing skills outside of divinity, combat and spellcraft.…

…that is, unless he can learn to exploit the hell out of it.

Calling the old god’s mage, the knight who inherits the bloodline, looking forward to the glory of yesterday;

The noise of steam engines and the roar of cannons indicate the direction of the future;

An Sen, who was living in this world, embarked on a road that had never been imagined;

In the ashes of the old world…he shall be crowned king!
