The Core of Spiritual Stone was a precious gem in the Heavenly Book. It was usually used to make all kinds of equipment and props. There were several ways to obtain a Spirit Stone Core: [1. Dropped in Instance Dungeons: The Core of Spiritual Stones often appears in various high-level Instance Dungeons such as the Heaven Pass Instance Dungeon and the Cave of Spiritual Stones Instance Dungeon.] Players could challenge these dungeons to obtain Spirit Stone Cores. 2. Complete daily missions: In the Heavenly Tale, daily missions can obtain a large number of rewards, including the core of the spirit stone. [3. Gemstone Combination: The core of the spirit stone can be combined with other gemstones to form more precious gemstones such as Starlight Gemstones, Resplendent Gemstones, etc.] [4. Acquired by trade: Some players will sell their own Spirit Stone Cores and can also buy them through the trading platform.] It was important to note that the Core of Spiritual Stones was a relatively precious resource. Players should use it carefully to avoid wasting it.
