Capital, city gates.
The largest city gate of the capital is called Chongyang Gate, with a long history, and the walls above and on the sides still bear marks left by many renowned literati and poets.
Unfortunately, it's all gone now. The two gates were directly blown away, and the entire entrance is barely standing. God knows how much gunpowder is secretly buried underneath.
After the gates were blown open, the Dragon Guard, who had been ambushing outside the city, immediately launched an attack, swarming through the breach into the city.
The Dragon Guard stationed inside the city also began to ambush the city's garrison.
The Chu Kingdom had been at peace for many years, and since its founding, the entire capital had never seen a foreign enemy, leaving its defenses emptier than a sieve.
