Immortal Water Lotus, a plant that harmonizes with Immortal Power, naturally comes with a Purity Divine Body.
The Purity Divine Body, simply put, is immune to all impurities that could affect itself.
Just as the First Ancient Emperor mentioned, to cultivate the Celestial Demon Finger, a cultivator must devour another's Heart Demon force.
The force of the Heart Demon generally repels cultivators, let alone seeking it out actively.
The Heart Demon poses the greatest threat to a cultivator, and must be overcome by the cultivator alone due to its contagious nature; assistance from others might lead them to also contract the Heart Demon, causing mental chaos.
Therefore, the process of cultivating the Celestial Demon Finger is extremely dangerous.
Because of this, the First Ancient Emperor suggested that Lin Jing's external avatar be created using Emotionless Stone as a material, following the Path of Emotionlessness, thus minimizing interference from the Heart Demon.
