Although the starry sea was a small world, there were millions of demonic beasts. The existence of low-level demonic beasts would only consume the resources and spiritual energy of high-level demonic beasts. At the same time, it was meaningless for high-level demonic beasts to exist.
In such a situation, rather than wasting the time and energy of high-level demonic beasts to capture and kill them, it was better to use the hands of humans to get rid of these useless 'same kind'.
After achieving their goal, the beast Kings had also investigated the strength of the humans and ensured that the sea of stars would not be lacking in spiritual energy and resources for the next few decades. Only then did the beast Kings take the initiative to sign a truce with the humans. This was the main reason for the cosmic Alliance!
From this, one could see how brutal and ruthless the beast King was.
