Lith is... dying?

In the dark place lit by the shine of the immortal core, Lith was meditating.

It had been a long time since he began pondering over things and finding no way out, he got up and stretched to break the barrier in front.

Stretching his arms, Lith said calmly, "If I can't use my brain to get out of here, I'll simply do what Lucy or Alexandra would've done in this situation." 

Lith chuckled after saying so.

He was trying to use his brain to come up with a logical answer to get out of here. But there was nothing it seemed and now the only way out was to resort to using force and break the barrier.

Lith did have the thought about breaking the barrier at the start but he also had another thought that it might complicate things.

That shiny immortal core was really special and one of its kind.

All immortal cores were unique in their own ways and this one here, it even had all the elements associated with it.
