This medical book, from the last era, was written by a doctor named Hua Tuo.

In this medical book, Dr. Hua Tuo explains in detail why it is more difficult for a person with advanced cultivation to produce offspring.

It turns out that the more powerful a practitioner is, the more terrifying energy is in his body. It can be said that every cell is extremely active and full of massive energy.

As a result, the more powerful the practitioner is, the more overbearing the cell is.

It is said that those practitioners who really stand at the top of the cultivation world can destroy a mountain with a drop of blood, and have the power to destroy heaven and earth when they turn their hands.

When you reach that level, it's hard to leave children by any means.

After all, it's no exaggeration for a cultivator of that level to say that every cell has no less energy than a missile, and it's almost impossible to leave offspring.

Therefore, the heirs of the great men are all the heirs left before they reached the summit.

In his medical books, Dr. Hua Tuo analyzed the practitioners of each realm.

First of all, it is in the stage of allogeneic ability. At this stage, the cells are only completely activated and have no effect on fertility.

Then there is the realm of awakening.

Once we step into the realm of awakening, our fertility will be affected. If we use proportion to say things, our fertility will drop by about 50%.

Fifty percent, which is still an acceptable number.

It's similar to, after excluding other factors, you should be pregnant once, but you need to use it twice to get pregnant.

Once you get to the extreme level of fertility, you'll have a 98 percent impact on your fertility!!!

This is a very shocking number!!!

That is to say, excluding other factors, we should have a pregnancy. Now, we need 49 attempts to have a pregnancy!!

As for the realm behind the awakening realm, the proportion is even smaller.

It's just a study of humans.

As for some other races, there is no specific study. However, it is certain that the reproductive capacity of monsters is superior to that of human beings.

Of course, in the face of this situation, those extremely strong races have come up with solutions. However, Huatuo does not give a clear answer in this book. Of course, it's more likely that Dr. Huatuo doesn't know how the major races solve the problem of fertility. After all, this kind of technology is a top secret for a race. If it's really leaked out, it is likely to be deliberately targeted by

opponents.

Now, of course, Lin ruofeng has no other way. Therefore, if he wants to have a child, he can only rely on the traditional old way to get a child through husband and wife life.

And now, he is already the cultivation of cognitive realm, and the probability of getting a child is only 2%.

It's a horrendously low probability.

As far as he knows, even if there is a statement on the condom, there is only a 97% chance of contraception and a 3% chance of pregnancy.

In other words, the practitioners of cognitive state cultivation are safer than using condoms!

No wonder his parents will come to Haitian city for the first time.

After listening to Lin ruofeng's explanation, the four girls looked at each other face to face. With such a low probability, it's very difficult for them to have children with Lin ruofeng.

Moreover, because of his own identity, Lin ruofeng can't stop practicing because he wants to have children. If his cultivation breaks through the cognitive realm, if he still doesn't have children, then he can't have children.

"Now you know the seriousness of the problem?"

Han Mei said seriously, "next you all have to work hard. I don't think you want to have no children in your life, do you?"

Four people you look at me, I look at you, are a little flustered.

As a woman, who doesn't want to have her own children? Even though Mo Yushi has children, Duoduo is her and her ex husband's children. Now she loves Lin ruofeng very much and wants to have her own children with Lin ruofeng.

"You have to work harder in normal times!"

Han Mei got up from the sofa and went to the kitchen. As she walked, she said, "I'll make delicious food for you. Tonight, you can start working hard."

After Han Mei left, only Lin ruofeng and her four daughters were left in the living room, staring at each other.

Finally, Lin ruofeng scratched his head and said awkwardly, "well, in the future, we won't have to take contraceptive measures. Now I'm safer than condoms!"

"Cough The cruel fact is in front of us, so the question comes: who is going to sleep tonight? "

"Bah, you'd better let five girls accompany you!"

The four women spoke almost in unison.This kind of thing, even if they want to, can't be said in the hall.

In the next few days, Lin ruofeng, Su Yiyi, Mo Yushi, and Zhou Zhilan all went astray several times. As for Xia Ziyin, it happened that her aunt was very unfortunate these days.

However, the 2% probability is not so easy to challenge?

Every morning, at the time of pregnancy test, the news is disappointing.

Finally, in desperation, Lin ruofeng could only give up the idea of making one of the women pregnant in a short time.

If you want to be quick, you won't be able to do it. It's better to let nature take its course. Maybe one day, who will be pregnant.

Of course, let him put it aside for the time being because there is something very important to do.

In a cafe in downtown Haitian

Lin ruofeng is stirring his coffee. Opposite him, there is an old man with white hair and beard. He is dressed in plain clothes, just like an ordinary old man.

However, if his identity were revealed, it would shock everyone.

Because this old man is no one else. He is the well-known and transformed turtle king from the Qinghai Tibet Plateau.

The turtle King appeared several times in the form of noumenon. Therefore, except for the people in the hidden dragon group, other people didn't know what the turtle king looked like.

If you know that the old man in front of you is the king of tortoise, it is estimated that the high-level of Huaxia will be nervous.

After all, this is the only known late cognitive expert in China, invincible.

All of a sudden, he was invited by the tortoise king. Lin ruofeng was still very surprised.

After all, if there were no important things for him, it would be impossible to find him. I just don't know what he is looking for.
