The Heaven's Might Soul Suppressing Formation is the formation used to seal Yun Canghai within Heavenly Sword Villa’s Sword Management Terrace. The profound strength of anyone inside would be suppressed to the maximum limit. It was strong enough to suppress a strength of late stage Sovereign Profound down to early state Emperor Profound. However the suppression did not affect Yun Che's profound strength because his profound veins came from a True God.
The formation also includes a huge sword called the Heaven's Punishment Sword. The victim is bound to the sword using Meteorite Chains. The formation is tied to the life of the victim, if the victim dies then the formation will be nullified.
