"By the way, elder martial sister, I have always had a question. Why did those mixed race species degenerate into death attendants? I already know the concept of blood boundary in the course, but there are some places that don''t make sense."

    The road is boring. Lu Chen turns into a good student who is open-minded and eager to learn.

    In the concept of hybrid species, once the proportion of genetic lineage of dragons exceeds that limit, human nature will gradually lose and gradually favor dragons, that is, the lineage will lose control and degenerate into death attendants.

    But the rickety man Lu Chen met was only of class B blood, and he heard that the higher the purity of blood, the higher the rating.

    In theory, class B hybrids are not high in blood and should be very safe. Shouldn''t it be class A and class s hybrids that are easy to get out of control?

    "I know what you want to ask, younger martial brother. I didn''t elaborate on this aspect in freshman year, so I understand that you have cognitive errors."

    Luticia explained: "first of all, younger martial brother, you should make clear that the purity of lineage and the proportion of human dragon genes are two concepts. Of course, the proportion of class A and s dragon genes is usually not low."

    Chu Zihang also opened his eyes and was obviously interested in this topic.

    "People of class A are more pure than those of class B

    Considering that Lu Chen had no higher education, Lucia tried to be concise and comprehensive, and took out an orange and divided it into two parts.

    "For example, there are so many of them, one is orange, the other is steel, of course, the nature is different."

    "Younger martial brother, you have a high proportion of lineage and high purity, but you happen to belong to a safe and stable category. From the perspective of genetic genetics, the probability of giving birth to the offspring of class s lineage is very low, which is even lower than the probability of winning SSR when you draw a card. Class s is like a gift from the gods to mankind."

    Lucia consciously used an easy to understand term.

    "What is SSR? Isn''t grade s the highest?"

    Lu Chen was puzzled and shocked. SSR sounded much better than S.

    He obviously didn''t get to Lucia.

    "It is the card with the highest rarity in some card drawing game, and the probability of winning is very small."

    Chu Zihang explained that he didn''t play either, but he was always knowledgeable.

    "So, whether it will degenerate into a dead waiter has nothing to do with the original pedigree rating, but it is usually easier for those with higher pedigree to degenerate, because the pedigree of their parents is not high, the proportion of human genes is relatively large, and it is difficult to produce a mutant. Therefore, it is generally out of control, and most of them are class A and class B hybrids."

    Lucia continued to explain. Lu Chen understood this time.

    In short, you were originally a weak person, and you are still not strong after falling, but if you want the purity of your original blood to be high, the changes after falling will be terrible.

    "The goal of our mission this time should have been a class a hybrid. When he crosses that line, his strength is definitely stronger than the normal class a hybrid. It''s even as good as your peak state, younger martial brother, so you can have snacks."

    Lucia turned her eyes when she saw Lu Chen looking at the scenery clouds outside the window again.

    Lu Chen turned to smile and asked, "elder martial sister, have you seen my peak state?"

    I haven''t seen her say that for a while, but Xi''a didn''t say it. At least she didn''t say it.

    "I heard you are good at profile writing, elder martial sister. Why don''t you guess what my spirit is."

    Maybe there will be a fight soon. Lu Chen is in a good mood at this time. He also wants to make a joke with his senior sister.

    Chu Zihang was also curious. He once asked Lu Chen about Yanling, but Lu Chen said he was still uncertain in his awakening.

    "Don''t guess!"

    Lucia turned her head angrily.

    ………………

    Standing in front of the huge French windows, you can have a panoramic view of Birmingham.

    Tall buildings in the distance rise straight into the dark and turbid sky, reminiscent of the bony peaks in landscape painting and the soul stirring stone forest.

    As night falls, the fog brought by industrial pollution becomes more intense, making people feel that there are some beasts hidden in the fog darkness.

    Lu Chen and others have just finished dinner in Birmingham. In the pursuit of task efficiency without delaying everyone''s time, Lu Chen wronged himself to eat only half full.

    The team consists of 20 main members and is divided into two teams. Team a is responsible for protecting milanella and team B is responsible for protecting Lucia.

    Now it''s a temporary meeting before the start of the task. It''s mainly that Lucia, who is good at profile writing, has a new conclusion after browsing all kinds of information on the road. She needs to let you know.

    "After summarizing the characteristics of the victim, I judge that slaughter has some kind of complex. Have you ever thought about why he is persistent in attacking women with these characteristics?"

    Lucia pointed to the big screen, on which the nine victims were lined up.

    "The nine victims have no connection in social relations. Apart from our Commissioner, there are no enemies before their lives. At least there will be no enemies who will kill them in that form. This is also the most important reason why we have no breakthrough now."

    Yes, serial homicide is one of the most difficult cases to detect, because such prisoners often commit crimes at random. They are not interested in revenge and killing. They may kill someone who looks "pleasing to the eye" at any time.

    Therefore, it is difficult to lock the suspect from the victim''s social network, but slaughter is not the same. His purpose is too clear. All the characteristics of the victim are the same, like some abnormal obsession.

    "Elder martial sister, do you mean to say that we haven''t found the inducement yet?"

    Asked Susie.

    "Yes, everything happens for a reason. If he just kills people at random, it''s difficult to do, but his behavior only shows one thing. There''s something that makes him obsessed with women with this characteristic. We haven''t found the first victim yet!"

    Lucia''s words immediately lifted the spirits of the people in the conference room and found a breakthrough.

    "The first victim, the unknown woman, definitely has a social relationship with slaughter. As long as we find her, it will be much easier to locate the murderer."

    Lucia said and saluted, saying that she had finished speaking, stepped back, and executive Filimon came on stage.

    "As Lucia said, I have mobilized the local police through tripartite forces to further collect information and inquire about the missing women who meet the conditions, but the women with report records do not meet the above characteristics, so I can only wait for the follow-up information from the police. In short, it is a good thing to make a breakthrough. After repair, I will act according to the original plan."

    There was a clear response from the audience, and the night owls from the execution department poured into the city.
