"I know this. In fact, I don't blame them. The main reason is that their ancestors are few. In order to get more people, they can only marry close relatives."

Yang Fan thought for a while, no matter whether the matter was true or not, he said directly.

"Why is this?"

The two asked in unison.

"This matter needs to go back to more than 2,000 years ago, that is, during the Qin Dynasty. Qin Shihuang wanted to live forever, so he sent Xu Fu to Penglai, which is now the country of Fusang, with three thousand boys and girls. It's just Xu Fu. I was very smart, knowing that I could not find the Pill of Eternal Life, and that I would die when I returned, so I took these virgins to live in Fusang Country."

"But you imagine how it is possible to create a country with only three thousand people. The Fusang country now has more than 100 million people. I don't know how long it will take to reach this level of country. So, Xu Fu ordered that Three thousand boys and girls are desperately creating human beings."

"But here comes the problem again. If you do a careful calculation, you will find the problem. If 3,000 people match, each couple will give birth to one child, and only 750 will be born. If luck is good, these 750 will have the same number of men and women. After thirteen or four years, only three hundred couples of couples can be gathered. That is to say three thousand artificial children, fifteen years later, about 750 more fertile people will be added. So those three thousand boys The virgins were born with the idea of ​​swapping wives, and when those children grow up more than ten years later, they can have children with those children."

Yang Fan used the fairy aura to calculate in the air, and he was shocked.

"In that case, wouldn't their relationship be messed up?"

"It's really messy. A woman can only give birth to one child a year, and fifteen years is fifteen. But there are so many people. Only two or three generations later will cause a very serious problem."

"what is the problem?"

It was Cheng Yufeng who asked, and she was also interested in what Yang Fan said.

"That is the consequence of inbreeding with close relatives. The offspring will often have congenital insufficiency diseases, such as stupid stupidity, underdevelopment of the body, or...shortness."

Speaking of being short, Yang Fan deliberately glanced at Ichiro Yanagi.

"Baga! The **** Zhizhi guy actually dared to insult my Great Fusang Country, **** it."

Yagyu Ichiro finally couldn't bear it, and roared out.

"Now you know why people in Fusang are so short."

Seeing Yang Fan ignoring him, Yanagi Ichiro drew his sword and slayed towards Yang Fan. He was in the shape of lightning, holding a long samurai sword high, and slashing at Yang Fan's head fiercely.

Ichiro Yanagi was very fast, from the time he drew his sword to appearing in front of Yang Fan, he didn't even blink.

"Be careful, this is killing God with a single blow!"

Cheng Yufeng exclaimed, it was too late to resist Yang Fan.

"Haha, **** that person, die, the five billion dollars is mine."

In a private hospital in Hangzhou, a withered Zhongfa was lying on a hospital bed, enduring the pain in his legs, his eyes fixed on the notebook in front of him, and the picture above was taken by the camera carried by the **** of death smiling. Picture.

"Die, you are dying, haha, **** kid, cost me five billion dollars."

Huh!

Yang Fan lightly sideways, the katana slashed close to his body, Yanagi Ichiro showed an incredible expression, the movement in his hand did not stop, and he controlled the katana to continue slashing towards Yang Fan.

Yang Fan shook his head. This kind of mindless sway with no moves has no effect at all. Although it is said that martial arts moves have been simplified, Yanu Shengyilang has not yet reached such a realm.

Ichiro Yanagi poured his energy into his whole body with every knife. Every time Yang Fan dodges, his killer attack will hit the ground. Every time he goes down, the ground of the square is chopped to leave a hole, which takes more than a minute. , The ground becomes riddled with holes, not to mention the car, even walking is more difficult.

"Zhi, will you just run away like a mouse? If you are a man, you should stand up and face my murderous slash, otherwise..."

Ichiro Yanagi looked at Sun Yunzhu and Chen Shuyue, which meant it was self-evident.

"Are you sure you want me to stop the killing **** who picked you up?"

Yang Fan showed a playful look.

"Of course, isn't your Hua Country famous for being magnanimous, show your master temperament, don't hide too much."

Ichiro Yanagi said in bad Chinese.

"Yang Fan, don't agree to him. The power of killing the gods with a single slash is very powerful, and the body protection of the Grandmaster Realm can't resist it. Many masters of our Hua country died under this trick."

However, Yang Fan remained unmoved, with one hand behind his back, giving people the style of a master without changing his face.

"Very well, Yang Fanjun, you have my approval. If you can survive without killing God, then I am willing to leave here and bet on my dignity as a samurai of Fusang country."

Yang Fan beckoned and motioned to Ichiro Yanagi to attack.

Ichiro Yanagi nodded, his face sinking, his hands clasped the hilt of the katana, the blade pointed at Yang Fan, took a deep breath, and rushed forward.

When Yang Fan was still four or five meters away, he leaped high, greatly increasing the power of Killing God.

"Aren't you worried about Yang Fan?"

Seeing that Chen Shuyue and the two daughters were not worried, Cheng Yufeng couldn't help coming to them and asked curiously.

"Why don't you worry about Yang Fan at all, aren't you afraid that he will die in the hands of Ichiro Yanagi?"

"Only this bastard? There is no one in this world who can hurt your husband. If there is, I think it will be us, provided that he is willing to be hurt."

"Did Yang Fan really step into the realm of a great master?"

Cheng Yufeng said suspiciously.

"Grandmaster? You should be talking about the foundation-building period. Don't use encounters compared with cultivation. The strength of your husband is not understandable by a mortal like you, and I am the same."

Although Chen Shuyue was only a golden immortal, she couldn't imagine the power of the immortal emperor, let alone Cheng Yufeng who was equivalent to the Qi refining period.

"Foundation period, cultivation..."

Cheng Yufeng thoughtfully, as if thinking of something in his heart.

Ichiro Yanagyu, who used the killer sword, came to Yang Fan in the blink of an eye. The strength of his body was released at this moment, and the samurai sword filled with all his strength was severely smashed.

Yang Fan raised his right hand and stretched out a finger.

when!

There was a crisp and loud metal collision, followed by the sound of the katana breaking.

The tip of the samurai sword struck the index finger, Yang Fan stood still, the samurai sword broke so fiercely, the remaining force caused the broken samurai sword to fly upside down and plunge into Ichiro Yanagi's body.

"This is impossible!!!"

Ichiro Yanagi couldn't pay attention to the blade inserted into his body, and couldn't believe that the person in front of him could actually block his full blow with only one finger.
