Treasures of the heavens are known as divine artifacts, capable of spontaneously conceiving a soul of their own, which is called an artifact soul.
Because this soul is spontaneously conceived by the divine artifact itself, it is known as an innate artifact soul.
Immortal supreme treasures, acting as immortal artifacts, lack the ability to spontaneously conceive a soul. They can only acquire one by sealing a certain living creature within the immortal artifact, turning it into the artifact spirit of the immortal artifact.
