In the first pages, it wrote—
[A spiritual beast can be many things, from a monster to a little cat, but using three of the best summoning techniques, and well, quite a lot of suffering, hehe, my disciple! I have made the best spiritual beast to summon. You don't summon him, you just create it and then add a refined soul into it. It will eat dead bodies, rotten plants and herbs, even blood and bones, and in its body it will create pills like healing pills, elixirs, spiritual qi gathering pills and elixirs, poisons, golden soul liquid—to help in soul cultivation and a few more things.
Its cultivation will be in stars. More you feed it, the more it will refine and become of higher levels.
Although it's a centipede, it can be used as a weapon like a whip, or tied around your arm like a gauntlet, or well, just use it as a reservoir for energy when your energy runs out. You can take it from this. Isn't that useful now, hehe.]
