The reason why the black emperor and the great wizard of the Shui nationality frown is that they are very familiar with Chen Hui's question. The probability of these three situations is quite different.

The sorcerers and warriors of any one of the five ethnic groups will be the first choice to find a mate, which is equal to their own accomplishments. Moreover, when a sorcerer chooses a mate, he will first choose a sorcerer. In this way, the offspring of the combination of the two will have a great chance of becoming a sorcerer.

The offspring of the combination of civilians will naturally have witches or warriors, but the probability is too small. It can even be said that the vast majority of the offspring of the combination of civilians will be civilians. It's very lucky to be a warrior. As for witches, it's very rare.

Witches and warriors will also marry civilians, but they will never be the right wife. They will marry civilians only when they have concubines.

Witches and warriors are still like this, not to mention the five nationalities and five emperors.

The partners of the five nationalities and five emperors, or three wives and four concubines, will never marry civilians.

Seeing the look of the black emperor and the great wizard of the Shui nationality, Chen Hui laughed and said, "don't misunderstand the black emperor and the great wizard. In order to ensure the purity of blood, the wizard chooses the wizard as the first choice when choosing his partner, and the warrior will also choose the warrior. This is a very natural thing. But just because of this, it's the right thing to say."

"What's that?" Asked the big wizard curiously.

"The dragon begets the dragon, the Phoenix begets the Phoenix, and the mouse's son can make a hole." Chen Hui said with a smile: "it's just a way of metaphor. It's really appropriate to describe the blood of the five ethnic groups."

Hearing Chen Hui's words, both the black emperor and the great wizard of Shui nationality laughed and shook their heads. Although this is the first time they have heard of it, it is very appropriate to describe it.

"In my opinion, it is not good for the five ethnic groups to abide by the current rule of non intermarriage." Chen Hui went on to say: "there is such a rule about blood. There has never been a marriage between men and women of two ethnic groups before. I can't prove the rationality of this rule. I can only see it as a kind of bondage to the five ethnic groups of human beings, but I can't see the advantages to the five ethnic groups of human beings."

The black emperor of the Shui nationality frowned and asked, "although I have known the tiger warrior for a short time, the tiger warrior has never been aimless. Since you can say that, there must be a certain reason?"

Chen Hui nodded silently and said, "naturally, there are some reasons, but it's not suitable to discuss with Heidi. I hope Heidi can trace back to the rules of non intermarriage among the five ethnic groups, and then we can discuss this topic again."

"In that case, I won't ask any more. The tiger warrior will wait for me for a few days. It will take some time to trace back to when the rule of non intermarriage of five ethnic groups came into being." The black emperor of Shui nationality didn't continue to ask, but left with the great wizard after saying this.

There is no doubt that the black emperor of Shui nationality will trace back to when the rule of non intermarriage of the five nationalities came into being.

Chen Hui is still living his own life step by step. He is also free in the aquarium. A few days later, the black emperor and the great wizard of the aquarium come to Chen Hui's residence in the evening.

As the king and Wizard of the Shui nationality, they are also very busy at ordinary times. Chen Hui also teaches the common people of the five nationalities medical skills and herbal medicine knowledge during the day. At night, he has plenty of time, so he won't be disturbed by anything.

The fact that Heidi of Shui nationality came here this time is obviously a result of what he said last time, that is, tracing back the rules of non intermarriage among the five nationalities.

However, this result is very unsatisfactory, and no result can be traced back.

After all, writing has just begun to be made by the five ethnic groups. Before that, there was no written record. Many things are basically handed down by word of mouth, such as the rule that the five ethnic groups do not intermarry.

This result is not unexpected. There are no words to follow. It only depends on word of mouth. Unless there are people who have lived for a long time, otherwise, there is basically no clue to trace back to the past.

Not to mention clues, even hope can be said to be No.

After informing Chen Hui of the result, the black emperor of Shui nationality naturally asked Chen Hui why he said the rule was not right.

Chen Hui said in a deep voice: "as the emperor of Shui nationality, Heidi must know how to practice Qi of Shui nationality. I can't ask Heidi about this question. I can only tell some results directly for reference of Heidi of Shui nationality."

The black emperor of Shui nationality nodded silently and motioned Chen Hui to continue.

"Heidi water belongs to aura. Does it exist in the kidney?" Chen Hui pointed to the position of his kidney and said, "the Shui people practiced Qi here at that time."

"How did the tigers know?" The black emperor of the Shui nationality frowned and asked.

The way of practicing Qi is different among the five nationalities. The location of aura in the body is also different.

Chen Hui has known this for a long time.

Because the five nationalities in this world correspond to the five elements, which is the knowledge of the five elements in the world that Chen Hui came from. Chen Hui is a very good doctor of traditional Chinese medicine. He can't be more familiar with the basic theory of Yin Yang and five elements. It's easy to infer such things from the known knowledge.

"I don't just know where the aura from practicing Qi of Shui nationality is stored in the body. I can say that I know where the aura from practicing Qi of five nationalities is stored in the body." "This is the information I infer by examining the patient's body," Chen said

"Can you tell me the details?" The black emperor asked immediately.

"At the beginning, I came into contact with the Mu people. When I examined the sick Mu people, I found a strange phenomenon." Chen Hui pointed to the location of the liver and said: "the liver of the Mu people is stronger than the other internal organs. This seems to be the characteristic of the Mu people. Later, I talked with the old wizard and confirmed this. The wood aura obtained by the old wizard's Qi training is just stored in this location."

After a pause, Chen Hui said: "this time, I have examined many people in Shui Hengcheng, including warriors and witches. Without exception, their kidneys are stronger than other internal organs. Compared with Mu people, Shui People's liver is normal, not as strong as Mu people's liver. I infer from this, The water that the Shui people get from practicing Qi belongs to aura, which is stored in the liver. Just now, they asked Heidi and got a definite result. "

"I see." The black emperor of Shui nationality nodded and said.

"In addition, I'm still teaching the five ethnic groups to cure their diseases, and I can reach the other three ethnic groups except Shui and mu." Chen Hui laughs at this.
