The Master Bai Feng of Baize Immortal City was originally an Individual Cultivator.
Later on, by a stroke of fate, he successfully formed his Core and then occupied what was once a trading area to establish Baize Immortal City, which has been around for several centuries by now.
It's just that a Core Formation Master's lifespan is so long, they outlive generations of Cultivators, making it seem as though they possess Immortality themselves.
In fact, Fang Xi did a quick calculation to realize that this Master Bai Feng was already over four hundred years old...
After outliving over a dozen of his disciples, could it be that the time had come for this Core Formation Master to be sent off by his disciples as well?
Fang Xi waved his hand to dismiss Zhong Hongyu, and holding a cup of Spiritual Tea, he fell into deep thought.
In this world, even Yuan Ying True Masters simply have to resign themselves to their fate and Sit and Transform or reincarnate when their lives come to an end.
