In the biological world, the higher the level of life, the lower the desire to reproduce, and the fewer offspring they produce.
Mice, sows, rabbits, and the like have astonishing birth rates; but for giant pandas, tigers, humans, and others, the birth rate is tremendously low.
In the Cultivation Immortality Realm, the main force of cultivator childbirth is primarily Qi Cultivation cultivators, Foundation Establishment cultivators, etc. They are the lower strata of the Cultivation Realm, unable to seek longevity, so they focus on descendants and clan, often having three to five Dao Companions, a dozen concubines, and over a hundred children.
But after reaching the Purple Mansion, many cultivators are so busy with the path of cultivation that they are uninterested even in beauty, let alone having children.
High-level cultivators often only begin to marry and have children in the last few decades of their lives, but it's a pity they can't conceive.
