My Most Esteemed Lord,

The latest experiment has met with complete success. I am pleased to report that our efforts to reverse-engineer vampiric technologies have yielded several breakthrough advancements. The technique known as “Iron Chrysalis” has now been successfully degraded and adapted for mass production, resulting in a type of vessel capable of sustaining soul vitality. I have tentatively designated this refined device the “Iron Crown.” While it does not confer the same absolute defiance of death as a lich’s phylactery, it nonetheless renders the bearer immune to mortality arising from corporeal destruction.

However, this is not the principal achievement. Many contemporary alchemical processes can already accomplish comparable feats of life preservation. The true significance of the breakthrough lies in the following: the Iron Crown not only maintains the host’s vital activity without reducing the subject to the emotionless state characteristic of liches, but actively cultivates and engenders desires and emotions—even within artificially created alchemical constructs. Once implanted, these beings cease to function merely as cold mechanisms of flesh and machinery. They will eat out of hunger, rage in anger, dance in joy, and curl in pain.

Crucially, all such responses remain fully subject to manipulation and control. These entities continue to be alchemical puppets in essence; yet far from risking loss of control, they will obey their master’s will with genuine willingness and devotion. To this end, I have integrated a psychic phantom matrix within the Iron Crown. The subjects’ cognitive models and emotional states may thereafter be arbitrarily shaped and directed by their designated owner. Should you so desire, they will regard the act of kissing your toes as the highest conceivable honor; alternatively, they may perceive their most beloved companion as a mortal enemy deserving of undying hatred. In this respect, I submit that their existence may well prove richer and more vivid than that of any naturally born being.

I trust Your Lordship is aware that the vampires once possessed another lost art. I have come to suspect, however, that its true origin lies not with the vampire race itself, but originates from some unknown realm beyond our world. I refer to the technique called “置闰”—the most merciless of formulae. It demands agony as tribute or fuel, and in exchange extorts from the target—or refines, transforms, strips away—certain esoteric and abstract essences, or simply serves as a source of raw power. Until now, I had been unable to produce this effect efficiently or at scale. That limitation has now been overcome. Although these puppets are artificial constructs, the emotions they experience are unequivocally genuine. By continuously modulating the source and threshold of their affective states, vast quantities of suffering may be harvested in a controlled and repeatable manner. I have accordingly established a large-scale energy production facility and hereby extend to Your Lordship a standing invitation to inspect the installation at your convenience. Enclosed with this missive are several vials of refined anguish together with a small number of alchemical puppets for your personal examination and assessment.

On a separate but pressing matter, I must respectfully lodge a formal protest against the sanctions recently imposed upon my operations in the frontier territories. I am firmly convinced that this measure cannot reflect Your Lordship’s true intent. I humbly beseech you to reconsider the matter in light of the tangible results presented herein. Surely Your Lordship can perceive that these research outcomes possess far greater substance and reliability than the empty promises and fabrications routinely offered by those demon lords who traffic in nothing but deceit. I earnestly implore Your Lordship to weigh this decision with the utmost care.

                    ------------------ Your most loyal servant,  
                                                                                                 Berith

我敬爱的领主：

新的实验很成功。我想我们目前对吸血鬼技术的逆向破解已经有了一些突破性的进展。”铁蛹“这一技术已经可以通过劣化，从而批量制作一种可以使灵魂保持活性的容器之中。我现在将它称为”铁王冠“。虽然它不能像巫妖的命匣一样让人随意的藐视死神，但它至少可以让人无视肉体的损伤而导致的死亡。

而这些都不是重点。当下大多数炼金术都可以做到这一点。最大的突破是，它不仅可以保持寄宿者的生命活性，不会像巫妖一样沦为无情之物，还会萌芽和催生欲望和情感。甚至包括人造的炼金生物。让它们不再是冰冷的血肉机器。在植入了这个装置后，它们也会变得有情感和欲望。它们会因为饥饿而进食，因为愤怒而狂躁，因为喜悦而舞蹈，因为痛苦而蜷缩。

而这一切都是可以被操纵和支配的。它们仍旧是炼金傀儡。却不可能会失控，反而会带着心甘情愿随着你的意志而行动。我在“铁王冠”内放置了心灵幻影装置。它们的思维模型和情绪则可以随意由主人支配。只要你想，它们便会将亲吻你的脚趾当作无上的荣耀。又或者将自己最亲爱的人当作自己血海深仇的敌人。就这一点上，我想它们的人生会比任何其他存在都要丰富。

相信您应该知道吸血鬼们还有另外一项失落的技术。但我感觉这门技术的源头不像是吸血鬼，而是来自与我们世界之外的未知之地。“置闰”。一道最残酷的公式。以痛苦为贡品或燃料，向目标索求，或用于提纯，转化，剥离一些神秘且抽象的事物，亦或者是单纯的用于充当能量。在此之前，我一直苦于无法高效且批量化的生产。但现在便有了。这些傀儡虽然是人造的事物，但它们的情感确实真实的。只要一直调节它们的情绪来源和阈值，就能得到大量的痛苦。至此，我已经建成一座大型能源工厂，欢迎您随时视察。至此，随行附带了几瓶精炼的痛苦和几名炼金傀儡。请您过目。

此外，在下严重抗议您对我在边疆事业的制裁。在下相信这绝对不是您的主意。请您再多做考虑。想必您也看到我的研究成果。这绝对会比哪些满口谎言和假话的恶魔领主有力得多。请您谨慎抉择。

                                   ------------------您忠诚的仆人，
