3 months of this shit and Cuck Cuck's isolated city is starting to fall apart. They can't do anything since every activity requires a month to complete, and we're disrupting every single one of them with the repeated raids.
No reinforcements are coming...and eventually they're down to the last 10,000 men when the fifth assault ended.
Yes, Xiahou Dumb. You've successfully defended indeed.
