This discussion on the Dao lasted for another half month.
Both Chen Yuan and Moluo gained much from it, obtaining some enlightenment.
Chen Yuan and Moluo are now basically on the same level, and only upon reaching a certain realm can one understand some of the doctrines discussed, which is why Lu Chengfeng only gave them pointers back then.
There was no real reason for a discourse on the Dao.
Chen Yuan's injuries also healed during this discussion, and then he chose to bid farewell, temporarily leaving Spirit Mountain, preparing to seek opportunities.
Moluo didn't know Chen Yuan's purpose, but he speculated it might be related to the Life and Death Crossing. As for why he had to go, perhaps only Chen Yuan himself knew.
There was no sorrow in parting, as Chen Yuan would have to return once he obtained his opportunity. Before leaving, he asked Moluo to help resist if the Southern Border or Northern Barbarians acted.
