Su Yang didn't have the ability to remember these details, but the three Crystal Skulls had no problem at all. These three fellows are ancient thieves, with a natural talent for tracking and treasure hunting, making it hard not to admire them.

Along the way, Su Yang and his companions encountered several groups of Demon Beast Saint Emperors. However, this time, they were not obstructed.
