Bab 347: Chapter 143: Shocking the Alliance! The Secret Food of Reincarnation Dragon (Requesting Monthly Tickets)

[Bone of the Skeleton Angel (Initial stage of five-star grade): One portion of the blood, flesh, and bone separated from the Skeleton Angel, forming a cage from its skeleton. It suppressed the Mechanism Country Gear during a threefold ceremony but was eroded over long eons, resulting in it taking on a gear-like form. Its spiritual nature has been tainted, and its quality has consequently diminished.]

This is the original bone of the Skeleton Angel that has been blessed by the Emperor of Hidden Corpses. It can be used to create Skill Secret Food — "Control of Skeleton", which grants mastery over the power of skeletons and the use of skills like Bone Spear, Bone Wall, Bone Prison and so on.
