The Yin Spirit is of the utmost Yin, and the Blood Qi is of the utmost Yang, both are substances of the body and mutually exclusive.
At a great distance, the Yin Spirit can even dominate and massacre body refiners without fearing them. But if the Yin Spirit gets too close, it is seeking death.
Under close distance, the fourth-tier Yin Spirit facing the extremely dense blood of a fourth-transition body refiner is like a drop of oil falling into a raging fire.
In an instant, Yun Shuang was almost completely destroyed, barely escaping the fate of having her soul scattered.
While trying to escape, Jiang Ming's Yin Spirit leaped out, unexpectedly manifesting a crescent moon and a great sun. Although they were somewhat illusory and hadn't transformed into tangible Dharma Phases, their soul power was incredibly terrifying. While rotating, they formed the Sun and Moon Forbidden Area where Yin and Yang were united, trapping Yun Shuang's remaining soul.
