Zhao Hai put in a lot of effort in learning the Buddha mystic art. His Hades was a large magical artifact, and Zhao Hai was only using a large magical artifact for simple collisions. The Buddha mystic art made up for this flaw.
It took Zhao Hai more than 100 days to master the stupa mystic art. After that, he began to practice the blazing devil wand mystic art. The blazing devil wand mystic art was not only about the usage of a wand. It should include the usage of all long weapons and magic tools, including the Jia tuo staff seal, the axe-splitting seal, the three halberds seal, the eight-leaf seal, and a few other hand seals.
It could be said that the blazing demon staff was a complete collection of methods to use long weapons and magic tools. Zhao Hai had put in a lot of effort in the process of cultivating it, and it took him nearly 200 days to finally master it.
