Is This A Guardian Beast?

Clang!

A middle-aged man raised a large hammer and slammed it into a plate, causing a resounding sound as those nearby closed their ears, grunting in irritation. But immediately after that, they inched towards the sonorous plate, staring at the barely visible dent on it.

"My god, how did you raise its strength to this level?" One of them muttered.

Another placed it on a stand and stood over it, seeing it only bend mildly, exclaiming in surprise, "How's it this tough?"

Considering its length, even steel of that thickness would bend more under his weight. So, it was a startling wonder as everyone expressed their admiration.

"Hehe, I've been thinking of creating a ship using this." Chief Yubak grinned in response, "Even the Empire's famed canons shouldn't be able to make a dent on it. Even when it's this thin, it should last a couple of hits from the cannon balls."
