Back when Chen Xuan was in the lower realms, he had already mastered the Great Dao of Time, but this was his first time witnessing the power of time immunity.
This type of immunity to the Great Dao was even rarer than immunity to thunder. Furthermore, cultivators who specifically practiced time-based spells were extremely scarce; once an ordinary cultivator encountered an immortal who controlled the Great Dao of Time, they would typically flee as far away as possible.
Although Chen Xuan had never encountered such a terrifying figure before, if he could extract this Forbidden Dao Crystal containing the power of time immunity and successfully fuse with it, he would at least not die an inexplicable death should he ever cross paths with a master of time.
