The interstellar heroine kills the world of cultivation

Tongtianjie Tiandao explained: "For living beings to reproduce, essence, blood, spirit and soul are indispensable. This spirit and soul is the inheritance of the soul. You should have noticed that low-level and primitive short-lived species often have extremely strong reproduction capabilities. However, it is much more difficult for long-lived species with high intelligence and high capabilities to reproduce offspring. This is because the continuation of offspring is actually restricted by the soul."

"When a new life is born, the soul factors of both parents must be injected when the essence and blood meet to form a new seed of life. Even if some special species are hermaphrodites and can conceive on their own, they still need the soul factors of the mother to be injected when they conceive in order to give birth to the next generation."

"Low-level, primitive life forms have souls that are still in their early stages and have a loose structure. This is reflected in the issue of offspring, that is, their soul factors are very easy to dissipate, and they can even release tens of thousands of soul factors at a time, thus obtaining thousands of offspring. But after such a large amount of soul factors dissipate, they may die immediately. Therefore, the shorter the life span, the more offspring they reproduce."

"And the more intelligent and capable a creature is, the stronger and more advanced its soul is. Only such a strong soul can support a creature's long life. But everything has its pros and cons, as reflected in the issue of offspring. The stronger the soul of a creature, the more stable its soul is. At the same time, out of instinct, it will do its best to avoid the situation of spiritual turmoil."

"As a result, the chances of both soul factors being injected at the same time when the essence and blood meet are low, so naturally, a life seed cannot be derived. In addition, each level of life has different requirements for soul factors when giving birth to offspring. For many low-level creatures, one soul factor is enough for an embryo. But if a high-level cultivator or divine beast wants to give birth to the next generation, at least tens of thousands of soul factors must be injected at the moment when the essence and blood meet. The more powerful the parents are, the more soul factors they need to give birth to offspring."

Feng Yuan nodded thoughtfully.

She felt that the theory of the Heavenly Dao in the Tongtian Realm made a lot of sense.

The relationship between fertility rate and level is not obvious in the interstellar world, but in every cultivation world she has visited, the fertility rate of ordinary mortals is much higher than that of the cultivator group.

It stands to reason that monks have long lives and much better living environments than mortals. The monk community also attaches great importance to the issue of offspring, and should have more conditions to reproduce than mortals. But in fact, many high-level monks do not have many offspring, and their offspring are often born when they are in the Golden Core or Nascent Soul stage.

This can also explain why in the interstellar world, even though the couple's physical examinations are normal and the frequency of sexual intercourse is completely in line with scientific guidance, they still cannot get pregnant. Because in addition to the conditions for pregnancy recognized by the interstellar world, there is another indicator: the injection of soul factors.

She asked Tongtianjie Tiandao: "What are the conditions for the injection of soul factor?"

The Heavenly Dao of Tongtian Realm said its conclusion: "It's actually very simple. As long as you act according to your instincts, the soul factor will naturally escape when both parties are in a state of spiritual confusion. However, the higher the intelligence of high-level creatures, the stronger their rationality. For example, cultivators in our realm will almost never have offspring after they have reached the stage of transformation into gods. This is because in the process of tempering the cultivators' path, their minds have been tempered to be extremely calm, and it is basically difficult for them to be emotional. Even if they are emotional, they will not devote themselves to it and enjoy it to the fullest."

"In this world, there have been cultivators who practiced the heretical way of taking Yin to replenish Yang or taking Yang to replenish Yin. The main purpose of their evil magic was to perform sexual acts between men and women with a heart of ice and snow, and when the recipient's spirit was shaken and soul moved, they took the opportunity to absorb the scattered soul factors. I don't know how these evil cultivators discovered and used this."

Fengyuan was thoughtful.

So it is better to have children early? Young couples are more likely to conceive when they are in love?

It seems that this conclusion is consistent with the actual data.

Tongtianjie Tiandao continued to explain: "Whether the parents' souls are strong or not is also related to the children's qualifications."

"Take the offspring of a cultivator as an example. They are also life seeds derived from essence, blood, spirit and soul. If the parents' souls are strong and the life seeds absorb enough soul factors, the child's talent will be quite outstanding. If the soul factor of one of the parents is not strong enough, or the life seeds do not absorb enough soul factors at that time, the child's talent will be relatively mediocre."

"In both of the above situations, a brand new soul is derived from the life seed itself."

"The last case is the combination of souls."

"You should also know that the soul has an immortal attribute. The soul of a living being basically does not disappear with death, but when the body dies, the soul will also be stripped of a lot of energy, leaving only a soul core."

"Among the life seeds produced by the union of monks, the soul factors of embryos that are barely conceived are very weak. Their soul factors cannot evolve into new souls on their own and can only serve as a primer to attract souls to settle in. With this primer, the soul core can be attracted to settle in the embryo, and after combining with the embryo, a combined soul will develop."

"Of course, there is also the possibility that the soul factor and the embryo may not combine successfully, and the embryo will die in this case."

"It's hard to judge the aptitude of children born from this kind of soul core combination. If they absorb a powerful soul core, they are likely to have excellent talents. But if they absorb an ordinary or even weak soul core, then their aptitude is not worth mentioning."

"As for mortals with much weaker souls, it is basically impossible for their offspring to generate new souls on their own. They almost always attract soul cores to combine with the embryos. If there are mortals with particularly high talents, they probably just happened to be lucky enough to attract a good soul core."

After explaining the mechanism of soul reincarnation, Tongtianjie Tiandao said: "So the purpose of 'Heavenly Curse' is actually to cut off the soul reincarnation of these sinners. When the soul is stripped of energy and becomes the soul core, the memory of the previous life will turn into a soul imprint and become silent. But particularly powerful souls can reincarnate with their memories."

"The souls of soul cultivators are much stronger than those of ordinary people. Even if they are killed by the thunderbolt I set, there is a high possibility that they will be reborn with their memories. After rebirth, they will continue to practice the evil art of absorbing other people's souls. Wouldn't that cause endless harm? One of the functions of 'Heavenly Curse' is to solidify the souls of these people, making them lose the ability to reincarnate."

"The derivative effect brought about by this is that their soul factor will not dissipate at all. Therefore, no matter how hard they try, even if they ask people in the science and technology district to artificially create embryos for them, they will not be able to have offspring. Because even embryos produced by artificial methods need to be injected with soul factors to generate new life."

Feng Yuan understood and said with a smile: "No wonder they change bodies like changing clothes all the time. I guess the effect of your soul solidification makes it easier for their souls to change hosts?"

Tongtianjie Tiandao admitted: "That's right. My original idea was that after the soul cultivators with resentment in their souls were marked by the 'Heavenly Curse', even if they survived the first thunder tribulation, the next thunder tribulation would be able to completely annihilate the solidified soul. Who knew that these guys were also very smart, and actually realized that the thunder tribulation was specifically aimed at soul cultivators like them, and from then on they even stopped practicing spiritual power to avoid the heavenly tribulation."

“However, although the solidification of the soul allows them to change bodies more easily, it also prevents them from expanding their tribe. This can be considered both an advantage and a disadvantage.
