The material the inner castle was made from was unknown. Following not too far behind Ji Dong, Miao Miao tried to test it and was surprised to find that even if she used the divine power from the Staff of the Earth Goddess, destroying the inner castle would not be an easy feat. At least, it was not something she could accomplish in a short time.
After climbing dozens of steps, the group soon reached the second floor. More than ten Dark Magicians clad in red robes were coming down from the second floor to meet them. Ji Dong could clearly feel that even more Dark Magicians were quickly nearing. The fact that no Purple Robe High Priest had appeared didn't mean those top powerhouses of the Dark Temple were drained by Chaotic Power. It was because they lived higher up in the Inner Castle of the Dark Temple and naturally could not reach this place as quickly as these Red Robe High Priests of the second floor.
