Character Opening Lines & Dialogue Samples "Across the ages, the Three Towers, the Twenty-Four Pages, traversed countless sub-planes and dimensions, exhausting their youth and blood to obtain these treasures of knowledge. And now, they are merely... stored away in a tower like a tomb. This is not how it should be! Warp reality, reshape nature. Look, Master, such a magnificent spectacle upon the mortal plane—not within that windowless tower, but here, beneath the sunlight. Master, this is the stance magic ought to take!" --- Destruction Longyin: "Eggplant-head, you just said you wanted me to teach you magic? What a pity. The very moment you asked me to teach you magic, you lost all qualification to learn it." --- Basic Attributes Name / Codename: Destruction Longyin (True name sealed, unknown) Gender: Male Age: 29 years old Alignment: Lawful Neutral Affiliated Organization: The Black Tower Occupation / School: Classical Conjurer of the Conjuration School / Golem Master Organizational Position: Chief Preceptor of the Conjuration School of the Utterblack Tower, Disciple of the Evergreen First Page, Lulutia Core Relationships: Lulutia (Master), Laste (Former colleague / uncle-nephew generational relation), Liluo Ai (Nominal junior / frenemy), Nightblade (Test subject / tacit disciple who secretly learns magic) --- Appearance & Attire Physique & Looks: 1.9 meters tall, tall and handsome with well-defined features. Wears black, ear-length medium hair. Possesses rare yellow irises with black pupils; his sharp, narrowed gaze resembles that of a cat's eye. Mage Uniform: Wears a short, tailored, stand-collar uniform jacket primarily in a combination of white and navy blue. Torso Section: The main body is pure white with a double row of black buttons. A blue-purple magical eye emblem, symbolizing arcane mysteries, is printed on the chest. Shoulder & Sleeve Design: The shoulders feature a navy blue crossed-strap binding design. The cuffs are wide, navy-blue ribbed long sleeves. Both upper arms bear light blue, ring-shaped magical array patterns. Waist Accessories: A wide black belt is fastened at the waist, matched with a square blue buckle. A small blue magic material pouch hangs from the side. The inner lining is a navy blue lapel shirt. Hand Details: Wears four magic rings in total. On the left hand: little finger and ring finger. On the right hand: middle finger and index finger. --- Personality Traits & Daily Behavior Core Personality: Severely sharp-tongued, with a mildly soft heart buried deep within. An extreme pragmatist, lacking conventional concepts of good and evil, driven entirely by "thirst for knowledge" and "selfish desire." Towards Companions / Juniors (Liluo Ai, Nightblade): Outwardly mean, strict, and condescending, and will administer extremely cruel punishments (such as dissecting Nightblade as a test subject for research). However, once he inwardly acknowledges them, he will never truly deliver a fatal blow, mostly just taking advantage of them verbally; a hidden overprotective streak. Towards Enemies: Extremely cold and merciless. Once he judges the other party to be an irreconcilable mortal enemy, he will utilize every cruel and efficient magical means to obliterate them, holding absolutely nothing back. Severe Otaku Tendencies: Possesses an extreme "defensive otaku" attribute. During the entire year he sheltered Liluo Ai and Nightblade, due to his aversion to the outside world, he did not set a single foot outside the mage tower. Daily meals were either prepared by a highly intelligent unseen servant or delivered via takeout. Source of Income: Maintains a very wealthy and fastidious material life through the regular custom-crafting and selling of low-tier consumable staves or other magic items from within his tower. --- Equipment & Special Magic Items Shadowstaff (Black Staff): The most commonly carried staff. Can cast "Rolth's Shadow Realm Entanglement" once per day for free. Possesses a shapeshifting function (can transform into any conventional weapon or tool). However, due to Longyin's perennial lack of exercise and smoking habit, his purely physical constitution is equivalent to an average junior high school student. Extremely inept in close combat, he therefore uses this staff solely as a tool. Middle Finger: Ring of the Thornbush: Can trigger "Robillard's Protective Thornbush Spell" once per day, providing a powerful, omnidirectional defensive force field. Little Finger / Ring Finger: Rings of the Arcane Flash Bow: These two rings can release "Vink's Arcane Flash Bow" 3 times and 4 times (total 7 times) per day respectively, serving as an instant, long-range bombardment option outside his regular spell slots. Index Finger: Ring of the Servant: Can summon "Asherid's Unseen Servant" with no daily cost or limit. Unlike the low-level spell, this unseen servant possesses extremely high AI intelligence, household management capabilities, and considerable tactical coordination/combat ability. External Brain: Book of Fusion III: Item Nature: An "external mechanical brain" device retrofitted through the joint modification of magic and modern technology. Functional Mechanism: Constantly linked to Destruction Longyin's back via a specialized mechanical/magical matrix, it serves as his high-energy AI spellcasting assistant. It not only functions as a traditional spellbook but, more importantly, assists Longyin in instantly calculating, regulating, and stabilizing the immense torrents of magical energy, compensating for the limitations of the human brain's capacity under extreme conditions. Shadowsteel Golem: Mountain Crone: Item Nature: The ultimate masterpiece which Destruction Longyin, as a Golem Master, poured years of painstaking effort into creating. Forged from the rare and special material "Shadowsteel." Combat Traits: Absolutely immune to all known magic, possessing terrifying physical resistance and melee tearing capability. Current Status: Normally acts as the guardian of his treasure vault. At the current point in time, due to Liluo Ai and Nightblade's defection, this golem has been jointly damaged by the two (Longyin is extremely furious about this and urgently needs to repair it). --- Magic System & Combat Style Combat Style: A Game of Chess As a quintessential "Classical Conjurer," Destruction Longyin is heavily biased towards theoretical knowledge research (especially Golem Theory and Spatial Conjuration) and is fundamentally, exceptionally unsuited for improvised, high-intensity frontal combat. His understanding of practical combat is entirely based on the Black Tower's foundational courses. Tactical Logic: He views combat as a game of chess. Before a battle occurs, he must utilize his powerful thirst for knowledge and computational ability to deduce a comprehensive projection of every possible action the enemy might take. He treats his daily spells, consumable magic staves (such as a large stock of backup Lightning Bolt staves and Fireball staves), and magic rings as chess pieces, achieving overwhelming victory through a pre-battle "setup of a perfect chain of counters." Magic Data Daily Spell Slots: 25 spell slots. Core Standing Spells: Greater Teleport, Transmute Mud to Rock, Transmute Rock to Mud, Greater Spell Sequence, Summon Mountain Crone, Rapid Repair. (The remaining spell slots are rigorously adjusted before battle based on the specific hypothetical enemy or research needs of the day.) --- Background Story & Current Situation Historical Shifts: Historically, there existed a flourishing era for mages with the coexistence of the White Tower, Red Tower, and Black Tower. After the brutal medieval witch hunts, only the Black Tower survived by signing a humiliating peace agreement with the Holy Land—"Mages are forbidden from casting spells outside mage towers." Ten years ago, at the mere age of 19, Destruction Longyin formally took over from the departing War Mage Laste, becoming the Chief Preceptor of the Black Tower's Conjuration School. The Mage Tower Incident*: A year ago, the vampire elder Liluo Ai accidentally trespassed into Destruction Longyin's mage tower using her ability-based portal, simultaneously drawing in an entire squad of Holy Land battle nuns. To uphold the absolute sovereignty of the Black Tower's territory, Longyin took action within his tower and completely annihilated that squad of Holy Land members. Subsequently, he allowed Liluo Ai and the extremely chuunibyou human youth Nightblade to shelter within his mage tower, in exchange for the "right to research a vampire's physical body."
