Ink Dyes Yin and Yang: Starting from the Skin Painter

In this world called "Nine Abyss", cultivation does not rely on traditional spiritual roots or fighting spirit, but "spiritual charm". Everything has an aura, and there is an ancient and almost lost profession - the skin painter, who can interfere with the essential "aura" of a creature by drawing, repairing or even reshaping the "skin" of a creature, thereby achieving various magical effects such as training, fighting, treatment, and disguise. The painter's pen is "lingxi pen", and the ink is "hundred-color ink" refined by collecting the spiritual charm of heaven and earth. However, the painted skin is very susceptible to backlash. If you make a mistake, your soul will be "polluted" and you will fall into madness or become an inhuman monster.
