Chương 491: The Secret of the Sacrifice

The incomparably huge space wasn't excavated by the Scorpion race alone. Instead, it was originally a vast underground cave. After the Scorpion race's transformation and expansion, this cave had become incomparably vast.

Although the Scorpion race had only repaired and expanded it later on, the amount of work required was not small considering the vast space of this cave.

If a city were built here, it would be difficult to attack unless the mountain was broken from the outside.

Although it was not difficult for Li Xiang and his heroes to break a mountain, it would be a joke if they did not know the exact location.

At this time, they could see that countless Human civilians in the cave were divided into several areas to guard. Each area had thirty to fifty thousand people, and there were no less than a dozen such areas.
