Capítulo 252: Scream

Liam patiently waited outside a large room that long, suppressed grunts resounded out of. 

He had his eyes closed in deep thought, unfazed by the disturbing cries that came through it now and again.

Liam's mind was still on the Ravenous Leash Arts.

In a way, it really worked like a body-inscription method, creating a tether between the core and the Beast Will.

That was where the name "Leash" came from. It simply imitated one.

For one, killing the beast was fine.

There was no other way to attain the core. 

All that was needed was the corpse, which was basically used as a puppet for the Art user to command.

It didn't need the cultivator's mental energy or 'Ora' to work, either, which was amazing in its own right. 

A single mental command was all that was needed to control it.

That said, it wasn't absolutely submissive to its master's will, as seen when the Metal Boar began its reckless thrashing.
