Strange Beast Essence Blood, a gathering of its life's very essence.
Generally speaking, once a Strange Beast reaches a level equivalent to that of a Cultivator's Golden Core Stage, it will possess essence blood.
Some Divine Weapons, and even Treasures, require essence blood in their forging. It's not just evil Treasures that need essence blood. Cao Zhen, drawing upon Zhang Daoling's knowledge of Immortal Cultivation theory, knows that many Treasures crafted by renowned and righteous sects also require essence blood.
Additionally, some Pills also require the use of essence blood.
Beyond that, setting up Formations and some special Talismans also necessitate essence blood.
Even certain Cultivation Techniques, if one wishes to practice them, require the aid of essence blood.
Not to mention those practicing demonic arts also need a large quantity of essence blood.
The stronger the Strange Beast, the stronger its essence blood naturally is, and the greater its effects.
