Although Tian Yu's idioms were a bit alarming, his general meaning was not wrong.
Blood Sea is an old Ghost Witch who has lived for several thousand years, and his Innate Divine Ability includes a whole set of methods for handling karma. The vast Blood Sea in his Heart Image World is karma manifested. All the karma that falls upon him will accumulate there, until it finally erupts at the last moment; at that time the Blood Sea will also fall together with it, severing that layer of cause and effect.
To put it bluntly, Blood Sea is the Witch among the Ghost Witches who is specifically responsible for dealing with karma and cause and effect, which can also be considered a kind of deceiving-heaven method. Throughout his life, Blood Sea has not been skilled at war; his main resources come from handling sacrifices and slaves for others, taking on karma in their stead.
