As the monster charged towards Gu Xi, he had already made his move.
Since it was the only means of ranged attack available to him, it was naturally Gu Xi's only choice.
This time, Gu Xi wasn't using the bone spikes as arrows or throwing weapons, but rather firing them continuously like a machine gun.
Anyway, Gu Xi's mana was sufficient, and he had no other spells to use, so he wasn't worried about consuming mana.
As for Corpse Burst, when the monster charged out, Gu Xi had already given up on it; this creature was too fast, and the zombies' bodies couldn't slow it down.
If he used Corpse Burst at that moment, the monster would have reached Gu Xi in no time.
As for preparing ahead, there needed to be a corpse in front of Gu Xi first.
Therefore, the bone spikes, like a machine gun, became Gu Xi's weapon of choice.
Faced with the low-level bone spikes, the monster didn't even bother to defend itself.
The bone spikes pierced into its body without even breaking the skin.
