To put it bluntly, it was very simple. After the infernal domain and the sacred sect joined forces, they naturally wanted to swallow the entire sword spirit world. However, there were a few powerful sects in control of the sword spirit world now. Each of these powerful sects was very powerful. Even if the sacred sect and the infernal domain combined their power, it was impossible to swallow the sword spirit world. Therefore, they came up with a solution, which was to use the power of the sword spirit world to consume the strength of the various sects in the sword spirit world.
Compared to other sects, the sacred sects had a natural advantage. They were a force of demonic cultivators. This might be a weakness in the sword spirit world, but one had to admit that it was also an advantage, especially in the aspect of communicating with demonic beasts. They had the advantage of the sky.
