"Here you go, please take this." Garrett held a test tube rack, distributing test tubes filled with 5ml of saline to each lined-up vampire. Mr. Seibesh frowned and said: "Master Nordmark, you are too inelegant, using test tubes for us to taste blood! ——At least you should use goblets!" His companions, whom he had brought along, nodded in agreement. Although Mr. Seibesh was just a viscount, he had considerable influence within the delegation and had brought four friends. Now, five flamboyantly dressed vampire gentlemen each held a test tube and complained in unison. Let me clarify, I am here to ask for your help in research, not to host a party. Goblets in the lab? Any professor seeing this would grab a broom and chase you out! But obviously, this is not how you speak to guests, as it would completely break diplomatic protocol. Luckily, Garrett was quick to react and calmly smiled: "Gentlemen, tasting our subjects with lab equipment is the romance of a researcher. If you are interested, how about I use the latest result from the lab to make a dessert for everyone? It’s a flavor you’ve never tasted before——" Mixed with magic in a low-temperature lab—where that student, Mick, who drank liquid nitrogen worked—stirred... Liquid nitrogen chocolate ice cream, smooth and creamy, deliciously sweet. The five vampires, each holding a clean beaker, were amazed and full of praise. "Beakers are from the lab, the stirrer is from the lab, and the liquid nitrogen is also from the lab." Garrett also held a beaker, carefully scooping up a spoonful. He held it until the mist from the ice cream dissipated, then gently crushed it against his palate with his tongue. Then, he began to smile, his eyes curving up like a mouse that had just stolen some oil: "The ingredients are rare. So, we only make a little after experiments when the professor is not around and quickly distribute it. Ah, such is the romance of a researcher..." The liquid nitrogen chocolate ice cream effectively soothed the vampires. When Garrett brought out the test tubes again, although there were a few grumbles, there were no more complaints. Garrett held a dropper, dropping fresh blood into their test tubes one by one. One drop, two drops, then he pulled out the dropper and moved to the next. Viscount Seibesh started complaining again: "Master Nordmark, you are too stingy. Just two drops of blood per person, the flavor is gone as soon as it rolls on the tongue!" "Yes, yes!" The vampires began to stir: "Master Nordmark, did you not prepare enough materials?" "If you were short on materials, you should have said so earlier! When we were leaving earlier, we could have made a detour to the [Sleepless Tower]!" Garrett wiped his sweat. Although one is a necromancer and the others are undead, what exactly is your relationship with the Black Crow Swamp, just going to get some blood? "Otherwise, we could just stroll around the streets—I believe, as long as the compensation is right, there definitely would be young, beautiful, chaste ladies willing to offer their blood..." No way! Garrett's expression changed slightly. The council hosting these foreign guests had one rule: not to violate the laws of Nevis. For example, the Orc race, no fighting or killing in the streets; and for the vampires, no "hunting" in Nevis! Even voluntary offers are not allowed! Before he could reply, the door was knocked twice. Then, a blond nurse—skinned over a skeleton—pulled a floating disc, delivering two full racks of blood samples. Each blood sample was neatly labeled. Determined from cross-matching experiments, the main and minor agglutination reactions. A dazzling array, more than a couple of hundred bottles. Garrett gestured towards the floating disc. "There are so many blood samples waiting to be tasted... one cup per person, wouldn’t your stomachs bulge by the end? Let’s go one drop at a time!" Hundreds of blood samples piled in front of them indeed managed to calm the vampires. They obediently picked up the test tubes, tasting the saline—and the two drops of fresh blood—like attending a wine tasting, occasionally debating over certain details: "This one definitely had red hair." "No, I think it should be brown hair... light brown, a bit brighter, but definitely not red." "This one, eighteen years old, a virgin." "No, no, no, at most sixteen years old! You were misled because she’s pregnant! Pregnant women have a fresh taste of the fetus in their blood—" "Pah, your taste is really weird! Actually sucking the blood of pregnant women!" Garrett had to admire. This blood sample came from a pregnant woman at a charity hospital who had a massive postpartum hemorrhage and was transfused nearly 3000 milliliters of blood, luckily surviving. Of course, her blood was drawn before childbirth... Although modern clinical research has discovered that around 7 weeks of pregnancy, fetal DNA can be separated from the mother’s blood, how could you determine it just by tasting? "Of course, tasted it." The vampires unanimously answered. Viscount Seibesh took a sip of wine to rinse his mouth, adding: "You’ll know once you drink enough. Of course, newly transformed vampires, young and inexperienced, might get it wrong..." Garrett breathed in, breathed out, in, and out. At this moment, he felt more confident about his plan to seek help from the vampires: No matter how the vampires recognized it, they could discern age, gender, hair color, high blood lipids, and even fetal DNA—this precision down to DNA should enable them to identify blood types, right? He clapped his hands: "Alright gentlemen. Next, I ask you to cooperate with my research—these blood samples, I’ve categorized into four types, can you discern their differences and commonalities?"
