In the Immortal Realm... the number of Immortal meridians someone possessed would determine how weak or powerful they were in battle.
That was something everyone knew. However, virtually nobody knew what sort of destiny or transformations would appear when someone corroborated the Dao on their own.
That was because in the Nine Mountains and Seas, only Kṣitigarbha had ever succeeded. However, now that Meng Hao had opened 123 meridians, the Dao Realm Patriarchs, as well as the true Immortal Chosen and Ancient Realm experts, were all completely shaken, and were beginning to realize that something else might happen.
Immortals who corroborate their Dao on their own can actually transform their Immortal meridians!
