Perhaps due to its unwillingness to die, or perhaps due to its lingering thoughts, under countless years of accumulation and various coincidences, the Blood Refinement World gave birth to an extremely special existence, called the Blood Shadow, or one could say, the Blood Spirit.
It was not only born of nature but also transformed from a drop of heart's blood of a powerful female creature after her death. In a sense, its existence is the continuation of the will of that female creature.
The essence of the Blood Refinement World is the remnant body of that female creature. In an environment like this, the Blood Spirit naturally can be regarded as the Heaven and Earth's Will of this entire world.
It is ignorant and unwise but possesses a trace of its own spiritual essence. Therefore, when the Nine Provinces cultivators invaded this realm, it instinctively reacted, which was to unleash Heavenly Punishment.
