The nine Swords 'successor

After he walked into the darkness, Zhao Xu took to the air and flew through this dark cave. He relied on his night vision and didn't need any lighting to activate it, so he was able to fly through the cave at high speed the entire time.

At this time, he was enchanted with the 4th-circle spell "greater wings of air," and his whole body's mobility had reached the perfect realm. Like an agile bee, he directly did all kinds of extreme movements in the winding cave tunnel.

Zhao Xu only slowed down after he had been driving for about 15 minutes and passed by no less than five forks in the road. He started to re-examine the huge square that he had just entered. The surroundings looked like an ancient arena, and there were only gray stones and yellow dirt everywhere. There was also a very tall building above him that was at least tens of meters tall.

The fungi grew on the ceiling and emitted a faint green fluorescent light.
