An ancient demonic cultivation technique that allows a cultivator to create a second, independent Nascent Soul. Once successful, the cultivator can possess two Nascent Souls. The second Nascent Soul can be fused with a suitable body to create a true second avatar/incarnation. This avatar can act and cultivate autonomously, far from the main body, effectively granting the cultivator a second life. However, there is a risk of the avatar developing a separate consciousness and rebelling against the main body.
