After Zhirui learned the Needle Rain Spell, he felt that the key to this technique wasn't its lethality, but the sheer number of needles and the wide area it covered, which made it very convenient to integrate into stealth attacks.
Having realized this, Zhirui attempted to blend Pine Needles into it, treating them as the true killing move, and he even abandoned the Needle Rain Spell's killing power in pursuit of increasing the quantity of needles to achieve a better hiding effect.
Roar!
Initially, when the needle rain hit the Black Bear Devil, it didn't catch its attention, as it felt as negligible as a scratch, barely breaking its fur.
However, unexpectedly, at the moment it lowered its guard, nine Pine Needles, carrying the power to break magic, pierced directly into the flesh of the Black Bear Devil. One needle even blinded its left eye, causing it to howl in pain and recklessly charge towards Zhirui.
