Within the Nine Halls of Hongjun Heavenly Palace, their internal structures are all quite similar.
Niao Cheng Divine Palace and the like, as an established divine palace, is not much different from Nuwa Divine Palace, except that the number of secret techniques in the Secret Technique Hall is slightly greater.
As for guidance in cultivation, when reaching Jing Yan's level, even if an ultimate powerhouse personally points it out, the help Jing Yan can receive wouldn't be significant.
Once one's strength reaches a certain level, each individual's path will differ somewhat. In terms of specific secret techniques, like the Hongmeng Dao Pattern, the Niao Cheng Palace Master could offer Jing Yan some guidance, and the Nuwa Palace Master could do the same. In fact, Jing Yan might not necessarily need guidance from anyone else.
