Wang Wei already knew who to choose as the last key speaker for the Soul Path, and that would be its founder — Liang Shixian. However, it took him some thought to choose the very first. There were few God Kings in the first place, and the best originated from the Divine Race. So, he chose someone who could establish an excellent standard for that area.
The preacher did an excellent job; his sermon was mainly about the Soul, as this was their expertise. The young Divine Race, named Red Ocean, took a page out of Jin Ye's book and discussed the balance between the Essence, Spirit, and Qi — but the main focus is the Spirit instead. This sermon lasted 2100 years.
