There were tens of thousands of arrays in the cultivation world, but these countless arrays were divided into a few major categories. The most important categories were attack and defense. If further divided, they were divided into enchantment arrays, illusion arrays, killing arrays, auxiliary arrays, and so on.
However, no matter how many types of arrays there were in the cultivation world, only a few types of arrays could be used by ordinary cultivators. For example, the defensive array of the barrier array, the array that could give early warning, the simple illusion array, and so on.
There were also some commonly used arrays, which were auxiliary arrays. These arrays were very simple and not very powerful. Their main purpose was to bring convenience to the life of cultivators.
