In the novel 'Devour the Stars', every character from domain lord to sector lord had a life core. The characters above the Immortal level were usually called the Immortal or the Eternal. They had a stronger life force and Life Providence. They no longer needed to maintain their lives through their Life Cores. The life force of the immortal came from the destiny. It was a mysterious existence that could give the immortal a powerful life force and supernatural ability. In the novel, the immortal could control the power of the destiny to adjust his life state, including the length of his life, the strength of his vitality, and so on. Although the Immortal no longer needed to maintain their life through their Life Core, they still needed to rely on the power of their Life Providence to display their abilities. For example, the Immortal could use the power of the Life Providence to speed up the passage of time and change the attributes of objects. At the same time, immortals also needed to use their Life Providence to activate powerful skills such as Life Siphon and Life Providence Break.
