Primordial World: I'm an Iron-Eating Beast, and Houtu Can Hear My Thoughts

P.S. This is primarily a Primordial World cultivation novel; the mind-reading is just there to spice things up. Also, don't ask why immortals supposedly can't read minds. Nobody said they couldn't-plenty of immortals in this story know mind-reading techniques.

Synopsis: After transmigrating into the Primordial World, he becomes the very first Iron-Eating Beast between heaven and earth, binds himself to the God-Tier Slacker System, and is taken in by Houtu, one of the Ancestral Witches, as her battle pet.

Gungun's stance: "Cultivation? Enlightenment? None of that matters. This little baby can get stronger just by lying around."

But for some reason, ever since that day, his poop-scooping caretaker Houtu has changed.

My name is Houtu, and I am one of the Ancestral Witches.

I keep a big, dopey bear as a pet. But for some reason, ever since that day, I've actually been able to hear its thoughts.

[I'm an Iron-Eating Beast, and beast milk is my favorite!]

[You can't even figure that out? What kind of Ancestral Witch are you?]

[Attain the Dao, attain the Dao... Are you really that desperate to change your name? Fine by me. With the Witch-Demon War just around the corner, I'll move to the Underworld ahead of time. That way, by the time I wake up from my nap, the fighting might already be over.]

Houtu: "???"
