The Ancient Magical Formation Spell set up by the Three Heads of Darkness wasn't big, and it was just as big as a classroom. A large number of Premium Crystal Ores were set up, and they formed many mysterious patterns. It seemed like a strange relief sculpture, yet it also seemed like a rarely seen altar. Even after Yang Ling pondered over it for a long time, he still couldn't make sense of it and couldn't discern the Magical Formation Spell's mysteries.
"Tsk, tsk. As expected of an Ancient Magical Formation Spell passed down by the King of Darkness, it's really awesome!" Yang Ling had carefully observed the Magical Formation Spell for a long time, yet he couldn't discern its mysteries, and this was why he could only give up. Soon after, he looked at the spatial crevice that recovered its calm and nodded in appreciation.
