What was the difference between the Nascent Soul and the Essence Soul in cultivation novels?

The Nascent Soul and Primordial Spirit were two common ways of leaving the body in cultivation novels. The differences between them were mainly reflected in the following aspects: 1. Different goals: Nascent Soul Out of Body refers to the cultivator condensing his Nascent Soul into a physical entity through long-term cultivation and moving it freely to other spaces. As for the Primordial Spirit Leaving the Body, it referred to the cultivator transferring his consciousness from the body to the outside world through special technical means. It was usually used to describe the scene where the protagonist discovered that he had mastered free consciousness in an accident. 2. Different effects on the body: The Nascent Soul needs to reach a certain realm in the cultivator's body to support the condensation of the Nascent Soul from the body into a physical body. Therefore, after leaving the body, the cultivator's body would be affected to a certain extent, such as feeling tired, weak, and so on. As for the Essence Soul Leaving Body, the requirements for the cultivator's body were relatively low. As long as the cultivator mastered the corresponding techniques, they could freely transfer to the outside world, but it might cause a certain impact on the mind. The three purposes were different. The Nascent Soul Leaving the Body was usually used to describe the improvement of a cultivator's realm and strength. It was a relatively advanced cultivation method. The description of the primordial spirit leaving the body was more used to describe the scene where the protagonist discovered that he had mastered free consciousness in an accident. It was interesting and dramatic. The Nascent Soul and Primordial Spirit were two common ways of leaving the body in cultivation novels. They were different in terms of the specific way of realization and the impact on the body, but they both represented the cultivator's constant pursuit of realm and strength.
