"The Skull Killing Skill" had undergone blood mist and twenty years of tempering, slaughtering ninety-nine innocent people. The birth dates and hours of these ninety-nine people all belonged to the yin. At the very moment of killing these individuals, the blood mist would extract the essence blood from their hearts using a secret technique to refine it, which was utterly cruel. The essence blood in the heart of every person is where the soul is most concentrated; this was essentially imprisoning a person's soul, never allowing them to be freed, forever unable to escape, and even in death, they would find no peace.
Humans have souls, but they are not as exaggerated as the legends describe. Every person's soul exists within their flesh and blood; it gradually dissipates at the moment of death. The few who can gather their souls together after death can extend their days in this world a bit longer.
