Heavy Metal

"Guoh…"

A burst of light emitted from a longsword and engulfed a small chamber filled with zombies. The light traveled in a dome-shaped effect, pushing away a large group of undead creatures of various levels and sizes. Once the burst of energy subsided, only one creature stood among them.

"Even an E rank can't do much against a weakness."

Rusty looked over the room filled with about fifteen dead zombies. Among them, two were of higher caliber, but even they couldn't do much against his burst of light energy. He had already figured out how elemental weaknesses worked in this world. His luck seemed to be great as many undead zombies roamed this seventh level and were quite susceptible to his light.

This floor was a lot different than the ones that came before it. They seemed to have their own mini-dungeons in the form of strange crypts. The swamp was mostly covered in mist, with entrances to these underground tombs well-lit with strange green flames. It was as if the dungeon heart wished to lure the adventurers inside their narrow corridors filled with traps, undead monsters, and poison.

However, the dungeon heart probably did not count on one of its monsters going rogue. Rusty was fully immune to any poison, disease, or foul stench that these monsters could use to attack the senses of adventurers. His body was also immensely sturdy and easily repairable with the large amount of bronze he had been able to gather.

"Is this what these adventurers risk their lives for?"

Each of these underground crypts held a lone chest in one of the large end chambers. This was the second crypt he had visited, and this one was also a letdown. Instead of pristine weapons or armor, the items were made from a rather strange metal.
