Chapter 55 Advancement!

The thunder lizard died, Karlo fell into unconsciousness, and Ybur was lost in thought for a moment.

The materials needed for Advancement generally prioritize symbolic significance and don't necessarily require a direct correspondence; thus, although the thunder lizard had scales rather than fur, its thick skin could actually satisfy the requirement of "thick fur." Furthermore, the armor-piercing spike that Karlo used to kill the first thunder lizard could also meet the condition of a "blood-stained blade."

Only that "symbol of reincarnation"…

Ybur looked thoughtfully at the unconscious Karlo.

Although Karlo completely failed to understand its meaning, perhaps Karlo's understanding wasn't entirely wrong?

Destruction followed by construction, death followed by rebirth, Phoenix Nirvana—could this also be considered a form of "reincarnation"?

But then again, is it really possible to use a living person as ritual material?
