After being bound to the learning system in my mother's womb, I became the empress

Chapter 365 The Emperor wants to know your blood type

Lingxiao Academy.

Lin Wushang received the emperor's letter and was thoughtful after reading it.

Why did the emperor suddenly ask about ways to verify bloodline?

Most people would never think of verifying their bloodline, unless... they have doubts about their own bloodline.

Could it be that the emperor doubts the identity of His Highness the Crown Prince?

Lin Wushang took the letter to Lin Xi and learned that she was in class, so he went to the classroom where she was attending class.

In the classroom, Lin Xi's biology class today happened to cover the chapter "blood type".

"In the last class, we talked about the components of blood. What are the components in human blood?"

The student at the bottom answered: "Red blood cells, white blood cells, platelets and plasma proteins (Baidu)."

Lin Xi smiled and said: "It seems that everyone took the class seriously and remembered it very clearly.

"So today we will talk about blood types. Different people have different blood types. What does blood type mean?"

Lin Xi turned around and wrote a line on the blackboard: "Blood type refers to the specific antigen type on the red blood cell membrane (Baidu)."

"Human blood types are basically divided into four categories, type A, type B, type AB, and type O. As for other rare blood types, they are beyond the scope of discussion in today's class.

“Students who are interested can come to me after class to find out more, or go to the library to look up relevant information.

"Now, let me explain to you the origin of blood types and their related applications."

When Lin Wushang came over, he happened to hear Lin Xi talking about the application of blood types - paternity testing.

His heart moved, isn't this exactly what the emperor wants to know?
So he walked into the classroom through the back door, sat in the last row, and listened to the class.

The students were all listening to the class carefully and did not notice his arrival, but as a teacher, Lin Xi naturally noticed it.

She was doing two things at once. While teaching the students verbally, she also used her inner strength to transmit messages to Lin Wushang, asking him, "Why are you here to listen to my lecture?"

Lin Wushang: "If I have anything to ask you, I'll talk to you after class."

Lin Xi didn't care about him anymore.

She took out a bottle of reagent and showed it to everyone.

There is a transparent liquid in a small glass bottle as high as a finger.

“This is a blood group reagent that reacts differently with different blood types.

"If you drop it into type 0 blood, the color of the blood will not change. If you drop it into type A blood, the blood will turn blue, type B blood will turn purple, and type AB blood will turn yellow.

"Does anyone want to come up and give it a try?"

Everyone raised their hands enthusiastically.

How could they not experience such a fun thing?

Lin Xi pointed at the student who raised his hand first, "Here, prick your fingertip with a needle and put a few drops of blood into this small dish."

The man complied.

Lin Xi put a drop of reagent on the plate and then showed it to everyone.

Everyone gathered around curiously.

Lin Wushang was also very curious, but it was not easy to compete with those students for a seat, so he sat still.

"Ah! The blood in the saucer turned purple!"

"It really changed color, it's amazing."

"Teacher, what is the principle of this?"

Lin Xi: "I'll tell you the principle later. Is there anyone else who wants to try it?"

Tried several more in succession.

"Hey, why hasn't mine changed color? Oh, I know, I have blood type 0."

"I'm AB blood type."

"Hey, I have blood type B."

Everyone seemed to be happy.

Lin Xi: "The class time is limited, so I won't give each of you a try. I will leave the reagents after class, so those who want to test it can do it themselves.

"Now, let me tell you what the use of knowing your blood type is."

She turned around and drew several tree-like distribution diagrams on the blackboard.

Then he explained: "The blood types in the upper two boxes represent the parents, and the blood types in the lower boxes represent the children. As shown in the picture, parents with these two blood types can give birth to children with the following blood types." A Parents with type A and type 0 blood can only give birth to children with type A and type 0 blood.

"Parents with blood types A and B can give birth to children with type A, type B, type AB, and type 0..."

After class, Lin Xi took Lin Wushang to his office.

After closing the door, he asked: "What's the matter?"

Lin Wushang took out a letter from his arms and handed it over.

"Do you know why His Majesty suddenly asked about the method of bloodline verification?"

Lin Xi looked at the letter without raising her head, "How would I know?"

Of course she wouldn't say it was her fault.

Lin Wushang didn't believe it, "Then why did you happen to talk about the blood type test?"

Lin Xi: "It can only be said that this is a coincidence. The progress of the course coincides with the emperor's letter."

Lin Wushang had a gut feeling that she had done something, but she didn't want to tell him, and neither could he.

Lin Xi read the letter and took out a bottle of blood type testing reagents.

"Ten taels of silver a bottle, do you want it?"

Lin Wushang: "..."

A few days later, the emperor received Lin Wushang's letter. Along with the letter, there was a small bottle of reagent.

After reading the letter, the emperor held the small bottle of reagent with a look full of doubts.

It turns out that different people have different blood types?
Divided into type A, type B, type 0 and type AB.

This reagent can be used to detect it.

There are also certain restrictions on the blood types of children born to parents with different blood types.

Parents with blood types A and 0 cannot give birth to children with types B and AB.

However, this method can only provide a rough check and cannot accurately verify blood relationship.

The emperor went to Fengning Palace with Lin Wushang's reply and reagents.

Let’s check it out with the Queen first.

The test results showed that the emperor had blood type B and the queen had blood type 0.

The Queen looked at the blood type genetic diagram drawn on the letter again.

"Our two blood types, the blood types of our children will be...type B and type 0?"

Emperor: "That's right."

Then the couple secretly performed blood type tests on a pair of children.

The test revealed that my daughter is type 0 and my son is type B.

The couple looked at each other.

Queen: "This can only mean that Wanwan may be our child."

Emperor: "It seems we have to find a way to know Xibao's blood type."

Of course, this matter can only be left to Lin Wushang.

After all, Lin Wushang is Xibao's sworn brother, so it is convenient for him to take action.

When he wrote the letter, the emperor felt very lucky that he had appointed Lin Wushang as the envoy of Di, allowing him to be his eyes and ears to gather information among the people.

Otherwise it would be really tricky to do this kind of thing.

Lin Wushang received the letter and opened it to see that the emperor actually asked him to find an opportunity to test Xibao's blood type?
An idea flashed in his mind, and some vague speculation suddenly surfaced.

He went to Lin Xi, "The Emperor wants to know your blood type. Xibao, you are the Emperor's daughter, right?"

Lin Xi did not answer directly, "You will know later."

But in fact, it has been admitted in disguise.

Lin Wushang had already guessed it, and there was no point in denying it.

"As for blood type, I have type B blood."

Lin Wushang: "Okay, I understand."
