Richard looked down at the underground city from the sky.
He was a little surprised.
This city was more like a war fortress than a city.
The city wall was more than 40 meters high. There were all kinds of siege crossbows on it.
Each of the siege crossbows had a striking bloodhoof mark. It was unforgettable.
These siege crossbows were different from the weapons on the ground. They were all made of steel, and their ferocious appearance was chilling.
Even the giant dragons would not be able to resist their hunting.
Behind the city wall, there were arrow towers of different heights. At a glance, there seemed to be more than 200 of them.
Between the gaps of the arrow towers, several catapults with strange shapes were ready to launch a fierce attack at any time.
They were armed to the teeth.
