Chapter 667 - Sacred Mountain

The huge aerial fortress was hovering directly above the crystal pit. A miraculous facility resembling a small town, it had an inverted, cone-shaped base and two layers of solid, ring-shaped walls. There were dozens of magic towers between the two city walls, providing protection to the fortress. It looked spectacular, of course, but there were also many flaws. Hao Ren could see that the fortress idea was very simple-minded: it was simply a fortress lifted up in the air; other than the turrets, it had no escort fleet or anti-aircraft weapons. It may have been a very powerful weapon on that planet, but it was far from invincible. This monster invention of Holletta was just a rudimentary design; it still had a long way to go before it would become a mature strategic application. Nevertheless, the aerial fortress was still an inspiring invention.
