Western Fantasy: I Can Upgrade Everything

Lighthearted and fun, with adventures, leveling up, laid-back daily life, and no female lead

After transmigrating to another world as an apprentice mage, Kevin discovers that he has a System that can upgrade anything.

A damaged Spark spell is upgraded into the first-tier Fireball spell!

A short dagger is upgraded into a fine steel dagger!

A raven's tail feather is upgraded into a thunderbird's tail feather!

While other adventurers are still working themselves to the bone for a single silver coin, Kevin already has a huge fortune and piles of spell scrolls stacked like mountains!
