The Heart Image Prohibition itself is indeed a powerful curse, but using it in the Shattered Domain is a complete waste. In the Shattered Domain, no Imperial would dare to manifest the Heart Image World, as it's akin to sending food straight into the mouths of the Outer Heaven Monsters.
Immortals can occasionally manifest it, use some tricks, and then must immediately flee.
In this sense, when an immortal uses the Heart Image World, it either means they think they can run fast, or they believe their flesh is thick enough that the Outer Heaven Monsters can't bite them to death in one go.
Thus, when the Witch Clan suddenly spent a great cost to prohibit the Heart Image World throughout Qingming, the many Imperials outside the Heavenly Vault were wonderstruck, not understanding what madness the Witch Clan had suddenly succumbed to. Could it be that they had too much power of sacrifice and needed to waste it furiously, or else they couldn't balance the accounts?
