Reverse Six-Eight Spirit General Technique. It is a type of magic art that uses the Eight-Person Talisman to command ghosts. If one could utilize this method well, before the Soul and Spirit completely scattered into heaven and earth, they could artificially—or rather, through a curse—create a vengeful spirit.
However, to create one like this, the biggest precondition was attached. They must be made to harbor strong resentment before death. It was entirely possible.
Ghost Sword had intense anger toward loyalty and the Seer, so he met the conditions to become a resentment, but at the very end, a single word from his daughter, Chunchu, dissolved all of it in an instant. That could be seen just by looking at his peaceful face as he took his last breath. -Why did you... stop?
At Blue Spirit's question, Mok Gyeong-un let out a faint breath and answered. -Because he cannot become a vengeful spirit. 'You have changed a lot.
Mortal.'
At Mok Gyeong-un's answer, Blue Spirit felt a strange mood. He was someone who could not feel any emotions other than anger, even more so than herself, a vengeful spirit. But now, he was somewhat responding to the emotions of others.
