To use an analogy it is like cracking open a watermelon.... only right when you open it can you enjoy the fresh juices
Any alluring female that has experience is obviously going to be a distraction from cultivation or an assassin. Poor cultivators spend their whole life sitting in some cave, or paranoid of near-bye sect members. With their terrible interpersonal skills, shown by the pleathera of face slapping young masters, its no wonder that these men's ego can not handle a real woman.
Because the authors are virgins that have no luck with women. Can't blame them. With Chinese men outnumber women by the hundreds.
China has something around 60 million more men than women due to their whole limited children thing back in the communist era where they got rid of most females born. Thanks to that the chances of men there ever finding a woman or a virgin one for that matter is likely next to impossible for these authors. So it becomes the subject almost all their readers can relate to desiring, thus in all their books.
The black hole easily. Any mortal can explore a treasure cave, a black hole on the other hand has ridiculous amount of gravity that no mortal can withstand. Not only would it be loaded with diamonds the size of planets giving me vast riches, it would also mean I have crazy godly powers as well. So yeah, keep your unexplored treasure cave, I'm now a freaking god! With a simple flick of my finger, you your treasure cave and the entire planet you are on will be turned to dust.
They also care much more for family or bloodline, at least in these novels. The purity could be taken as proof of being the one to impregnate the woman, at least that's what i think. What i'm wondering is, primordial yin or yang, do they age like wine, becoming stronger? Is it stronger for celestials as opposed to mortals or could an evil celestial use mortals as cultivation furnace, etc.
Is it really proof? After their first time they can take contraceptives and then go around 100 men. Its just wish fulfillment.
When these cultural habits formed i'm sure the only contraceptive was either abstinence or pulling out, but at least it'd avoid you marrying a pregnant woman. But yes, it's more like superstitious beliefs where they try to find solace in such thoughts, it's always possible to raise another man's kid. Well, maybe they had morning-after tea, like they do in novels, lol.
Imagine undressing in front of a cultivatress and she gazes upon your little brother and mockingly says "truly not the apex". This is why. Don't give them comparison material because long-term usage of cultivation pills gives shrinkage!
surely you know more about the situation than just the whole "the chinese could only have 1 child" rumour. this was not a wide sweeping law to all chinese, that was a restriction imposed on a single group that just happened to make the vast majority of chinese citizens, and was not so much an attempt to cull the population numbers, as it was to allow the minority groups to not be flooded out. yes there's more men, but thats the case in a lot of countries, theres also the reverse where a country may end up having more women. relationships are more than just 1+1= happy result. there are always vast swarms of people who simply don't actively aim for relationships too. the real influence if you look at it from this angle, is from china's history and the "roles of women" in the era on which cultivation novels are set. also, china has roughly 1.4 billion people... BILLION. 60 million is not much of a difference and even back in 2015 the spread wasn;t 60million, it was just 33 million more men than women. facts, not fiction http://www.worldometers.info/world-population/china-population/
