"Here, please take it."

"Please take it."

"Please take it."

Grete held a test tube rack and distributed test tubes filled with 5ml of normal saline to each vampire standing in line. Mr. Sebesh frowned and said:

"Mage Nordmark, you are so ungrateful that you use a test tube to let us taste blood! At least you should use a goblet!"

"Yeah yeah!"

The companions he pulled together nodded.

Although Mr. Sebesh is only a viscount, he has good appeal in the delegation and has attracted four friends at once. At this moment, five richly dressed vampire nobles, each holding a test tube, spoke with him.

Complain loudly.

Gretel: "..."

Please understand, I am here to ask you to help me participate in research and development, not to invite you to a banquet. What goblet is it? The goblet used in the laboratory?

Any teacher who sees this will pick up a broom and kick you out!

But obviously, speaking to guests like this will break down diplomatic etiquette. Fortunately, Gretel responded quickly, took his time and smiled immediately:

"Gentlemen, using experimental equipment to taste research objects is the romance of researchers. If you are interested, I will first use the latest achievements in the teacher's laboratory to make a dessert for you? I guarantee it will be a taste you have never tasted before.

"

milk.

cream.

granulated sugar.

yolk.

cocoa powder.

In the cryogenic laboratory, the laboratory of Mike, the classmate who drank the liquid nitrogen, used magic to mix and stir the liquid nitrogen...

Liquid nitrogen chocolate ice cream, delicate, smooth, sweet and delicious.

The five vampires, each with a clean beaker in hand, ate with great admiration and were full of praise.

"The beaker is from the laboratory, the stirrer is from the laboratory, and the liquid nitrogen is also from the laboratory."

Gretel was also holding a beaker, and carefully scooped up a spoonful with a small silver spoon. He held it in his hand until the white mist on the ice cream dissipated, then put it into his mouth and lightly crushed it with the tip of his tongue.

Then, he laughed, his eyes crooked, like a little mouse that had just stolen oil:

"Materials are rare. So, after we finish the experiment, we can secretly make some while the teacher is away and distribute them quickly. Well, the so-called researcher's romance is like this..."

The liquid nitrogen chocolate ice cream soothed the vampires very well. When Gretel brought out the test tube again, although some people still grunted, they stopped complaining.

Gretel took the dropper, one by one, and dripped blood into their test tubes. One drop, two drops, pulled out the dropper, and the next. Viscount Sebesh began to complain again:

"Mr. Nordmark, you are too stingy. Each person only has two drops of blood. If you roll it on your tongue, the taste will be gone!"

"Yes, yes!" The vampires began to cheer:

"Mr. Nordmark, did you not prepare enough materials?"

"If you don't have enough materials, you should have told me earlier! When we left just now, we could go to the [Tower of Sleeplessness] for a tour first!"

Gretel shook his head. Although one is a necromancer and the other is an undead creature, what is the relationship between you and Black Crow Swamp? You just want to get some blood?

"Otherwise, we can go around the streets. I believe that as long as the compensation is in place, there will be young, beautiful, and chaste ladies who are willing to donate their blood..."

No! Grete's face changed slightly. There is one rule for the Parliament to receive these foreign guests: they are not allowed to violate Nevis's laws and regulations.

For example, the orcs are not allowed to fight or kill people in the street; another example is the vampires, who are not allowed to "hunt" in Nevis!

Not even voluntary!

Before he could answer, the door had been knocked twice. Then, a blonde female nurse with a sweet smile pulled a floating saucer and brought two shelves full of blood samples.

Each bottle of blood sample is clearly labeled.

Type A, Type B, Type AB, Type O.

The classification is determined based on the results of the cross-matching test and the primary and secondary agglutination reactions.

There is a dazzling array of products, more than one or two hundred bottles.

Grete smiled and raised his hand towards the floating saucer.

"There are so many blood samples waiting to be tasted... If each person drinks one cup, wouldn't his stomach bulge after drinking it? That's not possible, let's do it drop by drop!"

Hundreds of bottles of blood samples were piled in front of them, and they succeeded in calming the vampires. They honestly picked up the test tubes and tasted them one by one:

"This is a little girl. Commoner. Age... about ten years old. Blond hair."

Awesome. Gretel looked at the label of the first blood sample, and it was from little Jenny. The question is...how did you taste it just by tasting it?

"This is a young man. About 20 years old. Commoner. Brown hair."

"This... old man, no, he should be middle-aged or older, forty or fifty years old. Damn it, he's so fat!" Next to Viscount Sebesh, another young vampire let out a sigh, his face distorted:

"Master Nordmark, you owe me once, you really owe me once! Normally, I would never touch such bad blood!"

Grete gave him a thumbs up. The label on the blood sample bottle showed that this blood sample did come from a wealthy businessman.

Therefore, high blood lipids are normal. As for whether they have gout, Grete is very curious whether they can taste high uric acid, but unfortunately, it is not written on the label.

The vampires held the test tubes, sipped the saline solution and the two drops of blood dropped into the saline solution, and evaluated them seriously as if they were participating in a wine tasting party. Occasionally, they even argued over some details:

"This must be red hair."

"No, I think it should be brown hair... light brown, a little brighter, but it can't be red hair."

"This one is eighteen years old and a virgin."

"No, no, no, sixteen years old at most! You were disturbed because she was pregnant with a child! A pregnant woman can taste the fresh taste of the fetus in her blood."

"Bah, your hobby is so weird! You actually suck the blood of pregnant women!"

Grete had to admire it. This blood sample came from a pregnant woman in the workhouse who suffered from postpartum hemorrhage and nearly 3000 ml of blood transfusion. She was saved by luck. Of course, when the blood sample was taken, she had not yet given birth...

Although modern clinical research has found that fetal DNA can be isolated from the blood of pregnant women around 7 weeks into pregnancy, how can you be sure by relying on your tongue?

"You can taste it."

"Of course I can taste it."

The vampires answered in unison. Viscount Sebesh took a glass of wine to rinse his mouth and added:

"You will know if you drink too much. Of course, compatriots who have just been transformed into vampires are young and inexperienced and may make mistakes..."

Gretel inhaled, exhaled, inhaled again, and exhaled again. At this moment, he was a little more confident in his plan to seek help from the vampires:

No matter how the vampires identify it, in short, the ability to taste age, gender, hair color, high blood fat, and even fetal DNA can identify blood types accurately, right?

He clapped his hands "papa":

"Okay, gentlemen. Next, I would like to ask you to cooperate with me in researching these blood samples. I have divided them into four types according to their types. Can you taste their differences and similarities?"
