阴暗的地牢中，潮湿而冰冷，空气中充斥着腐烂臭味和人类体味，闻上去令人作呕。
In the dark dungeon, it was damp and cold, and the air was filled with the stench of decay and human body odor, which smelled disgusting.
地牢长满青苔和苔藓的墙壁上，每隔几米就插着一根浇油火把。火把“噼啪噼啪”的燃烧着，因为空气缺乏流通、氧气含量过低，正散发着因为不完全燃烧而产生的黑气，把一道道身影照在地上，看上去扭曲而惶恐。
On the walls of the dungeon covered with moss and moss, there are oiled torches stuck every few meters. The torches were “crackling” burning, because of the lack of air circulation and low oxygen content, they were exuding black gas from incomplete combustion, casting figures on the ground, looking distorted and terrified.
“滴答滴答”，地牢顶部凝结的水滴不断的落下，滴在一名地牢看守士兵的头上，一点点的打湿头发，打湿脸颊，最终流进脖子，冰冷无比。但站着的看守士兵却是一动不敢动，全身的肌肉紧绷成一块，如同一根龙骑兵的标枪插在地上。极力维持着平稳的呼吸，眼睛的余光却是不由自主的飘向地牢的入口处。
“Tick tock, tick tock”, the condensed water droplets on the top of the dungeon kept falling, dripping on the head of a dungeon guard soldier, wetting his hair and cheeks little by little, and finally flowing into his neck, it was extremely cold. But the guarding soldiers who were standing did not dare to move, the muscles of the whole body tensed together, like a dragoon’s javelin stuck in the ground. He tried his best to maintain a steady breathing, but the peripheral vision of his eyes drifted involuntarily to the entrance of the dungeon.
入口处，一个少年，一个十五六岁的少年，身穿有些过于简单的贵族服饰，正面无表情的走进来。在少年的身后，地牢看守队长唯唯诺诺的陪着，满脸堆笑，目光则忐忑不安、害怕无比。
At the entrance, a teenager, a fifteen or sixteen-year-old boy, dressed in somewhat too simple aristocratic costumes, walked in with no expression on his face. Behind the boy, the captain of the dungeon guard obediently accompanied him, his face was full of smiles, but his eyes were anxious and frightened.
不由得看守队长不怕，少年是国王的小儿子，是除了大王子外，下一代国王的第二顺位继承人。只要对方有一点的不高兴，他随时都有可能身首异处。
The guard captain couldn’t help but not be afraid. The boy is the youngest son of the king, and besides the eldest prince, he is the second heir to the next generation of kings. As long as the other party is a little unhappy, he may be decapitated at any time.
想到这里，看守队长的内心绷得更紧了，脸上的表情都有些僵硬。
Thinking of this, the guard captain’s heart became even tighter, and the expression on his face was a little stiff.
李察却没有过多在意看守队长的神态。来到当前这个类似于中世纪的世界已经十五年了，超常的心理可以让他做到完全适应身份，并知道如何去做才能更效率的完成自己的目标，继而解开自己的一个终极疑惑。
However, Li Cha didn’t pay much attention to the guard captain’s demeanor. It has been fifteen years since he came to this world similar to the Middle Ages. His extraordinary psychology allows him to fully adapt to his identity and know how to do it to accomplish his goals more efficiently, and then solve one of his ultimate doubts.
“哒哒哒”，李察一边踩着地面向着地牢里面走去，一边对看守队长出声道：“之前我让你带队抓捕巫师，或者和法术、不正常的超自然现象有关的人给我研究，你已经先后执行了两次了，没有一次成功，都是抓一群长相丑陋的农夫来凑数。而现在，是第三次了，你确定你真的抓到了？我的耐心可是有限的。”
“Da da da”, Li Cha stepped on the ground and walked into the dungeon, and at the same time said to the guard captain: “Before I asked you to lead a team to arrest wizards, or it might have something to do with spells or abnormal supernatural phenomena. The person who gave me the research, you have implemented it twice, and you have not succeeded once, and you have caught a group of ugly farmers to make up the number. Now, it is the third time, are you sure you really caught it? My patience But limited.”
“王子殿下，这次……这次……”看守队长的头上瞬间冒汗了，喉结抖动了几下，生硬的声音从喉咙中传出，“这次……这次我一定保证是抓到真的。”
“Your Highness, this time… this time…” The guard captain’s head was sweating instantly, his Adam’s apple trembled a few times, and a stiff voice came out of his throat, “This time… this time I will definitely Guaranteed to catch the real one.”
“那说一下，这次你抓了些什么？”李察道。
“Then tell me, what did you catch this time?” Richard said.
“是，王子殿下。”看守队长深吸一口气，回答出声，“这次一共是抓了四个，一个白脸魔，一个半身人，一个吸血鬼，还有一个……”
“Yes, Your Royal Highness.” The captain of the guard took a deep breath and replied, “This time we caught four in total, one white-faced devil, one halfling, one vampire, and one…”
……
……
“哒哒……哒！”
“Da da… da!”
半响，李察停在地牢深处某处牢房前，眯眼看着牢房中的一个身影。对方脸上的肤色呈现一种不正常的雪白，没有任何的血色，显得异常的恐怖。正坐在牢房的地上，目光惶恐不安的看来。
After a while, Li Cha stopped in front of a certain cell deep in the dungeon, squinting at a figure in the cell. The complexion on the opponent’s face was an abnormal snow-white without any blood color, which looked extremely terrifying. Sitting on the floor of the prison cell, his eyes looked anxiously.
看守队长声音响起，唯恐李察没有看出来道：“王子殿下，这就是抓到的白脸魔，你看……”
The guard captain’s voice sounded, lest Li Cha didn’t see it and said: “Your Highness, this is the white-faced demon caught, look…”
李察只是瞥了一眼，迈步就走向前方。
Li Cha just glanced at it and walked forward.
看守队长一愣，不知道李察为什么毫无兴趣，但还是一缩脖子，跟上去。
The guard captain was taken aback for a moment, not knowing why Li Cha had no interest, but he still shrank his neck and followed.
很快，李察的第二次停下，旁边的一个牢房中，一个有些怪异的身影，正蜷缩在角落中。对方脸上满是皱纹，看上去五十岁不止，但身高却不足一米，如同一个孩童，让人看来不由得生出诡异的感觉。
Soon, Li Cha stopped for the second time, and in a nearby cell, a somewhat weird figure was curled up in a corner. The other party’s face was full of wrinkles, and he looked more than fifty years old, but his height was less than one meter, like a child, which made people feel weird.
看守队长解释：“王子殿下，这是半身人……”
The guard captain explained: “Your Highness, this is a halfling…”
话没说完，李察摇摇头，迈步又走向前方，然后停下。
Before he finished speaking, Li Cha shook his head, walked forward again, and then stopped.
第三处牢房中是一个怪物般的人类，外表苍白，脸、脖子、手背等裸露在外的皮肤满是红斑，有些地方甚至已经腐烂掉。嘴巴微微张开，能看到对方的牙齿好像长的出奇，呈现妖异的血红色，令人看了不寒而栗。
In the third cell was a monster-like human being, with a pale appearance, and the exposed skin on the face, neck, and back of the hands was covered with red spots, and some places had even rotted away. The mouth is slightly opened, and one can see that the other party’s teeth seem to be surprisingly long, showing a strange blood red color, which makes people shudder.
“王……王子殿下。”看守队长指了指这第三处牢房的人，明显有些紧张，出声道，“这是吸血鬼，你一点要小心点，不要被他伤到。”
“His Royal Highness… Your Highness.” The captain of the guard pointed to the person in the third cell, obviously a little nervous, and said, “This is a vampire. Be careful not to be hurt by him.”
“呵。”李察出声，语气有些冷。
“Heh.” Li Cha said, his tone a bit cold.
“王子殿下，你……”
“Your Highness, you…”
李察出声道：“一个白化病人、一个侏儒还有一个卟啉病患者，就是你抓到的白脸魔、半身人和吸血鬼？”
Li Cha said: “An albino, a dwarf, and a porphyria patient are the white-faced devils, halflings, and vampires you caught?”
“这个……”
“This…”
“你到底有没有生物知识？！好吧，我忘记了，中世纪根本没有生物知识可言，但这根本不是理由！你用脑子想一下也该清楚，如果他们真的是白脸魔、半身人和吸血鬼，你能这么轻松的抓来？”
“Do you have biological knowledge?! Well, I forgot, there is no biological knowledge at all in the Middle Ages, but this is not a reason at all! You should think about it with your brain, if they are really white-faced demons , halflings and vampires, can you catch them so easily?”
“额，这个……”
“Ah, this…”
“不说别的，就说吸血鬼，你见到他像传说中化身蝙蝠了？又或者会飞？”
“Don’t say anything else, let’s just talk about vampires. Did you see him as a bat incarnate in legend? Or can he fly?”
看守队长身体颤了颤，下一刻却是强打勇气：“王子殿下，我的确没有看到这个邪恶的吸血鬼会化身蝙蝠、飞行，但是他身上的皮肤的确真的不能见阳光，一见阳光就会腐烂的，你看他现在的样子就是因为路上被阳光照到的。我带人抓他的时候他也正在喝着血，而且而且也特别讨厌大蒜……”
The captain of the guard trembled, but the next moment he was brave: “Your Highness, I did not see that this evil vampire would turn into a bat and fly, but the skin on his body really cannot see the sun. It will rot when exposed to the sun, you can see that his current appearance is because of the sun shining on the road. When I led someone to arrest him, he was also drinking blood, and he also hated garlic…”
“你听说过卟啉病吗？”
“Have you ever heard of porphyria?”
“啊？”看守队长一脸愣怔，“卟……卟啉……”
“Huh?” The captain of the guard looked stunned, “Porphyrin…”
“卟啉病。”李察重复一遍，面无表情的出声道，“人体中的血液有很多部分组成，其中一部分叫做血红素。一般来说，人体内利用‘铁元素’和‘卟啉’，在特定酶的催化下就能生成血红素。
“Porphyria.” Li Cha repeated, with a blank expression on his face, “The blood in the human body is composed of many parts, one of which is called heme. Generally speaking, the human body uses ‘iron’ and ‘Porphyrin’ can generate heme under the catalysis of specific enzymes.
但是一些人因为缺乏这特定的酶，血红素生成会出现障碍，导致体内‘卟啉’这种物质含量极高。而‘卟啉’这种物质对光非常敏感，在黑暗里无害，一旦见光、被紫外线激活，就会转化为一种“嗜肉”毒素，导致人体表面出现大面积的红斑、疱疹甚至溃烂~IndoMTL.com~而口腔也会受到影响，牙龈溃烂、牙根暴露，从而显得牙齿特别长，又会因为卟啉的沉积而渐渐变成紫褐色。
However, due to the lack of this specific enzyme, some people will have obstacles in the production of hemoglobin, resulting in extremely high levels of the substance ‘porphyrin’ in the body. The substance ‘porphyrin’ is very sensitive to light and is harmless in the dark. Once exposed to light and activated by ultraviolet rays, it will be transformed into a “carnivorous” toxin, causing large areas of erythema, herpes and even Ulceration~IndoMTL.com~The oral cavity will also be affected. The gums are ulcerated and the roots of the teeth are exposed, making the teeth appear particularly long, and they will gradually turn purple-brown due to the deposition of porphyrin.
同时，因为无法合成血红素，无法产生正常血液，卟啉病患者会有严重的贫血，必须从外界补充血液才能活下去。静脉输送是一个好办法，但考虑到当前这个世界的科技水平，他们根本无法操作，只能选择另一种——饮用——血红色生命力极其顽强，可以抵抗住各种消化液，能进入消化系统通过小肠吸收。
At the same time, because they cannot synthesize hemoglobin and cannot produce normal blood, patients with porphyria will suffer from severe anemia and must supplement blood from the outside to survive. Intravenous delivery is a good way, but considering the current level of technology in this world, they can’t operate it at all, so they can only choose another way—drinking—the blood red vitality is extremely tenacious, can resist various digestive juices, and can enter the digestive system Systemic absorption through the small intestine.
他们之所以讨厌大蒜，也很简单，因为大蒜中会有大蒜素，具有强烈的杀菌作用。因为他们身体的特殊情况，食用大蒜会诱发并加重他们的症状。其实你用银质的物品去刺他们，他们一样会讨厌，因为银也有强烈的杀菌作用。
The reason why they hate garlic is also very simple, because there will be allicin in garlic, which has a strong bactericidal effect. Because of their special conditions, eating garlic can induce and aggravate their symptoms. In fact, if you stab them with silver objects, they will hate them, because silver also has a strong bactericidal effect.
你要明白一点，吸血鬼是吸血鬼，卟啉病是卟啉病。也许两者的表现有些相同，但是并不是完全等同！我让你们找的是真正和吸血鬼一样的、和巫师、法术有关的东西，而不是一个个的病人，懂吗？
You have to understand that a vampire is a vampire and a porphyria is a porphyria. Maybe the performance of the two is somewhat the same, but not exactly the same! What I want you to find is the real vampire-like, witches, and magic-related things, not individual patients, understand?
当你在抓捕他们的时候，受到的不是抵抗和杀戮，而是哀求和哭号，就应该心里有点数了吧？之前两次是这样，这第三次还是这样，我的耐心真的是有限的……”
When you were arresting them, what you received was not resistance and killing, but begging and crying, so you should know something about it, right? It was like this twice before, and it’s still like this the third time, my patience is really limited…”
“王子殿下我……”守卫队长已经说不出话了，内心被巨大的恐惧占据。他听到过王子殿下很多冷酷的手段，如果王子真的发怒了……
“Your Highness, I…” The captain of the guard was speechless, and his heart was filled with great fear. He has heard many cruel methods of His Royal Highness, if the prince is really angry…
李察却没有继续和守卫队长纠缠，迈步走向地牢最深处，出声道：“你说这次一共抓了四个，最后一个是真正的巫师？好吧，那让我看看，是真是假。”
However, Li Cha did not continue to entangle with the captain of the guard, walked towards the deepest part of the dungeon, and said: “You said that you caught four in total this time, and the last one is a real wizard? Well, then let me see, Is it true or false.”
