The Formation Flag, this thing, primarily focuses on trapping.
But if the focus is on killing, it can, although it consumes more spiritual power than a trap.
It's usually used in guarding passes or gates, letting enemies willingly jump into it.
Otherwise, setting up a formation on the battlefield to kill is futile if no one breaks the formation.
The old man from Corpse King Star uses the one hundred and eight Heavenly Punishment Earthly Annihilation Great Formation, not by setting it up, but by using spiritual power to urge the banner spirits to actively engage the enemy.
He knew that sealing Long Fei with this flag, considering his ordinary realm and understanding of the basics of Space Law, was nearly impossible.
He shouted angrily, "Immortal Banner Spirit, devour all things!"
One hundred and eight black Command Banners fluttered, gathering a series of black figures above the old man's head.
These figures were all skeleton-like.
