The Mithril Basilisk

As the giant monster adjusted its body inside the cave, Melina and I stood perplexed at the sight with our mouths wide open.

If a monster were immune to magic, then I would have to rely on physical strength. However, the basilisk's body was fully covered in mithril, so even if I used all of my strength, I doubted I would do any significant damage.

It was even worse for the princess, as she pretty much relied only on magic to fight. She wasn't weak by any means, but she also wasn't strong enough to do anything in this scenario.

Taking a few steps back with care, the princess opened her void pocket, pulled out a hunting knife with a dark green-colored blade, and then handed it to me without taking her eyes off the monster.

"What's this?" I whispered, trying not to get the monster's attention.

"It's an adamantite knife. I can't think of anything else that can hurt it…" she explained.
