The End

"Adrian's 20th wave has arrived! This time the Destroyer is a black wyvern! Let's see if Adrian can hold his ground against the Destroyer this time! Or will he surprise us again by defeating it quickly?"

The crowd watched with bated breath as the monstrous black wyvern approached, its massive wings creating powerful gusts of wind with each beat. The wyvern's scales glinted ominously in the light, its eyes burning with a malevolent red glow.

"Look, the 20th wave has arrived! Let's watch how Adrian will fare against the Destroyer!" the female announcer's voice was filled with suspense.

"Wait, why aren't the archers and mages doing anything? Why is Adrian standing still?" the male announcer asked, confusion evident in his tone.

Indeed, Adrian and his troops remained motionless, not a single arrow or spell being launched towards the approaching behemoth. The audience murmured in confusion, trying to understand the strategy behind Adrian's inaction.
