She's a Powerful Mage

Feng Yiyi has a blade.

Any living being slain by it loses its soul forever, with no chance of reincarnation.

One day, the blade goes missing.

Not long after, her enemy shows up in front of her, brandishing the blade and taunting her.

Feng Yiyi smiles and pulls out a bow. "Want to see who dies in the end?"

Enemy: "???"

Later, the enemy finds a way to take her bow, too.

Feng Yiyi strikes the enemy in the chest with her palm.

"Still don't understand? It's never the weapon that makes someone lose their soul forever."
