The southern expedition was easier to advance than anticipated.
The only reason for the delay was that there were too many amusing incidents along the way, resulting in daily entertainment.
For instance, NPCs could be resurrected; however, due to the mechanics of this created world, there were some inconsistencies, making their friends and families' reactions quite bizarre.
It manifested in that NPCs knew their brothers had died, they also knew their brothers had come back to life, but the latter did not replace the former.
Because the "First Under Heaven" had sufficient spirituality, they could quickly sort out their logic, and since they had always lived with such realities, it didn't feel off to them.
But the average NPC seemed very clumsy and caused a lot of hilarity.
Players personally witnessed Soldier B, who had returned from death, having a meal with Soldier A. In the middle of the meal, Soldier A started crying.
