Thud!
The shiny sword in Damian's hand banged hard against the stone wall. Damian felt a slight dull pain spread from his grip onto his muscles upon the hard impact.
Damian's eyes darkened slightly, and his expression turned grave. However, he quickly regained composure and pressed on. For the next few seconds, he unleashed a flurry of consecutive swings.
Thud!
Thud!
Thud!
Despite his efforts, the stone walls stood firm, like a tank shrugging off a series of bullet hits. Or a bear being poked by peebles.
Yawn...
Merlin let out a yawn, his expression betraying a touch of boredom. "Is this really all you've got? If so, I have to say, it's quite disappointing."
Damian's eyebrows twitched slightly, but he didn't bother to retort. As he realized his attacks weren't making a dent in the stone wall, Damian, suddenly took a few steps back as if already giving up.
