Chapter 555: Four 4s Are Enough

Another man asked, "According to what you said, the blood test is no longer valid."

Shen Xia said directly: "You use chicken blood and duck blood to test, and they can be integrated! Are they from the same family?"

The man choked and immediately wanted to try it again, because no one had ever tried it this way, how could it be possible!

Someone will want to ask about it right away.

Shen Xia simply didn't have that much time to explain to everyone.

"It's urgent now, and I don't have time to explain so much to you. In a word, donating blood is good. Your blood has been in your body for a long time. Donating blood can promote your blood metabolism, increase immunity, reduce the risk of cardiovascular disease, and other benefits."

At this time, the man who had stopped her from saving people said, "With so many benefits, why don't you offer them?"

"I can donate! The important thing is that donating blood requires rest. If I rest, who will save him? It's up to you to donate or not. If you don't want to donate, just go away." Shen Xia said bluntly.

After all, she disliked this person from the first sight.

People's sixth sense is sometimes very accurate. If you instinctively hate someone, it means that your magnetic fields are not compatible.

At this time, two young teachers came forward.

"Let me try it!"

"I'll try too."

For those who can come in to rescue people, the yard is still next to them.

You have to win someone's favor no matter what. Adults think differently.

Shen Xia looked at the two of them: "Okay."

At this time, everyone saw that the master had come forward to donate blood.

Many scholars were willing to do so.

After all, scholars care more about reputation.

You know, they are willing to use their own blood to save others, which is probably a good story.

In the end, it doesn’t matter whether you really want to donate blood or just pretend to want to donate blood.

This man is always enough.

Because the table over there was the crime scene and they couldn't go there now, Shen Xia could only ask someone to carry the table and bench out.

An adult male can donate 200ml-400ml of blood, so the people inside now only need 1000ml.

Only three men are enough, but they are not used to donating blood, so it is better not to draw too many.

Shen Xia plans to use it for four people, and 250ml is enough for each person.

The equivalent of four 250 is enough.

Seeing that so many people were willing, fortunately, Shen's mother had prepared everything for her.

Shen Xia took out the ABO test paper directly from his pocket and the results would be out in ten minutes.

Take out a stack of papers.

Shen Xia looked at everyone and said, "Those who are willing to donate blood, please line up and have your blood type tested. The man inside has type B blood. You must have type B and type O blood to donate blood."

It sounds like your own blood may not be used, but some people line up out of curiosity, especially when they are curious about their own blood type.

Shen Xia looked at the twenty or thirty people lined up.

It won't take that much.

There are also younger ones.

Shen Xia said to the people queuing behind him, "Those who weigh less than 100 kilograms should not queue up, and those who are under 15 years old should not queue up either."

Although everyone didn't quite understand, they thought that since the princess said so, there must be a reason.

Shen Xia didn't care. It would be enough to interview fifteen people first.

It is impossible that there are not four suitable blood types among fifteen people.

Shen Xia took out disposable utensils without font packaging.

Looking at the first man: "Sit down! What's your name?"

The man said respectfully, "Chen You."

Shen Xia wrote down her name, otherwise we wouldn’t know who is suitable when the results come out.

The man didn't know what Shen Xia was going to use and felt a little embarrassed.

"Hand out."

The man didn't know what to do, but he did as he was told.

After thinking about the differences between men and women, Shen Xia pretended to do something.

Get out a pair of rubber gloves and put them on.

See the man stretch out his hand.

Just hold the man's hand.

Under his surprised gaze, I pierced his index finger with a needle, and it started bleeding immediately.

Immediately drop the blood onto the test strip.

It was enough. He wiped him with iodine, then took a cotton swab and pressed it and said to him, "Press it yourself and don't move. You can throw it away after a while when the bleeding stops."

Chen You nodded: "Okay,"

He had never seen such an operation in his more than ten years of studying.

But if students are in trouble, he must come out to help, even though he is not sure about it.

The curious people nearby also watched.

Shen Xia put the used test paper aside.

Then one, two, three, ten to fifteen.

There are fifteen pieces of paper lined up next to the desk.

Shen Xia directly said to the sixteenth person: "The ones after that don't need to be tested."

The man was puzzled and asked, "Ah! Why?"

Shen Xia explained: "I only need four people."

Dean Bai thought to himself, could we find four people out of fifteen who had the same blood as Liu Zefeng?

He asked cautiously, "Princess Anping, aren't these fifteen people too few? What if we can't find four with the same blood? How about trying a few more?"

Shen Xia shook her head: "No, there are only four common blood types, and now any other two blood types will do. In fact, four can be found out of ten people. Testing fifteen people now is just for safety reasons."

When Dean Bai heard this, he realized that there are only four blood types.

His learned heart was stirring again.

If it weren't for the wrong time, he would have many more questions to ask.

But the other teacher is waiting for the result.

He couldn't wait any longer, so he asked, "The princess is saying that among us present, there are only four blood types."

Shen Xia nodded: "Well, if nothing unexpected happens, then?"

The Master was confused again: "What do you mean by no surprises?"

Shen Xia explained: "The common blood types are only A, B, AB and O. But some people are special and have other blood types. However, there is only one person with this blood type in 10,000 people. So if nothing unexpected happens, everyone present will only have these four blood types."

The teacher wanted to ask again.

Shen Xia waved her hand: "The previous results are out, she will take a look and explain them to you when she has time."

Shen Xia looked at the first three test papers.

Only the first one, Master Chen You, was type B.

Shen Xia took Chen You's and said, "Please come over here, Master Chen."

Master Chen came over and said, "Princess Anping, is this my Ke Yi?"

Shen Xia nodded: "Yes."

Then he looked at the second and third pieces of paper, called out their names and told them their blood types, saying that theirs were not suitable, and Shen Xia put the papers in his pocket.

Her things cannot be left outside.

Shen Xia looked at Chen You with a worried look on her face.

He smiled and said, "Don't be afraid, your blood is very healthy. Drawing only 250ml will only benefit your body and not harm it."

Facing Shen Xia's peaceful smile, Chen You's originally slightly nervous heart immediately calmed down.

Shen Xia took out a blood bag and a syringe from the bag.

Looking at Chen You: "Show me your arms."

Chen You felt a little embarrassed.

Although the man was looked at his arms, what was wrong?
