Klein immediately realized that the metal used by the Iron-Armored Puppet in front of him was very rare.
Furthermore, it was a strange metal that was currently unknown. It should have been refined from a special material.

Klein guessed that this metal was probably refined through a special device. Ordinary weapons were no match for him.
James was also somewhat shocked that the weapon in his hand had completely lost its effectiveness.

He thought for a moment before saying, "Should you use your tier 10 weapon again? It looks like only a top-tier weapon can deal with this terrifying opponent!"
