第一章 九又四分之三站台的青色悖论

The Cyan Paradox of Platform Nine and Three-Quarters

Leonard, an earthling, travels to Hogwarts and awakens the powers of the Seven Gods of Teyvat (wind/rock/thunder/grass/water/fire/ice), but he needs to gradually unlock them through the sacred relics of Hogwarts' underground leylines - the statue of the God of Wind in the Astronomy Tower, the statue of the King of Rock in the Chamber of Secrets, the Fountain of Wisdom in the Forbidden Forest... Each sacred relic contains a thousand-year contract between the ancient elemental wizards and Hogwarts.

As Hermione Granger's distant cousin, his wandless levitation and rock-lance combat astonished the wizarding world. Hermione, with her photographic memory, translated these powers into learnable "elemental spells," becoming his sole theoretical partner. From using wind to generate bay leaves in Potions class, to using a rock shield to block the basilisk's petrifying gaze in the Chamber of Secrets, to using lightning to split the Dementor's black mist in Azkaban, the two redefine the possibilities of magic through the complementary "wisdom and power" of the original novels.

As the power of the Seven Gods is gradually released, Leonard discovers that Voldemort's Horcrux is actually a "crystallization of abyssal energy", which can only be destroyed by the corresponding power of God's Eye - the Rock King's Spear shatters the golden cup, Wuxiang cuts off the diary with a single blow, and the Echo of Green purifies the poisonous fog... and Hermione pieces together a bigger truth from the family genealogy and "A History of Magic": the gargoyles and leyline obelisks of Hogwarts, and even the entire magical world, are all in line with the elemental laws of Teyvat.

When the final battle came, the shadows of the Seven Gods appeared over Hogwarts. The Wind God swept away the Death Eaters, the Rock God held up the city shield, and the Thunder God cut off the dark magic... Leonard and Hermione stood in the center of the seven-pointed star, weaving the fate of the two worlds with the resonance of elements - it turned out that as early as a thousand years ago, the authority of the Seven Gods had laid the foundation for the protection of the world.

地球人莱恩纳德穿越霍格沃茨，觉醒提瓦特七神能力（风/岩/雷/草/水/火/冰），却需通过霍格沃茨地脉圣物逐步解封——天文塔的风神像、密室的岩王雕像、禁林的智慧泉……每个圣物都藏着古代元素巫师与霍格沃茨的千年契约。
作为赫敏·格兰杰的远房表哥，他的无杖悬浮、岩枪战斗震惊魔法界，而赫敏凭借过目不忘的天赋，将这些力量解析为可学习的“元素咒文”，成为他唯一的理论搭档。从魔药课上用风元素催生月桂叶，到密室中用岩盾硬接蛇怪石化凝视，再到阿兹卡班用雷电劈开摄魂怪的黑雾，两人在原著经典场景中，以“智与力”的互补，重新定义魔法的可能。
随着七神权柄逐渐解封，莱恩纳德发现伏地魔的魂器竟是“深渊能量结晶”，唯有对应的神之眼力量才能摧毁——岩王枪粉碎金杯、无想的一刀斩断日记、绿野回响净化毒雾……而赫敏从家族族谱与《魔法史》中拼凑出更大的真相：霍格沃茨的石像鬼、地脉方尖碑，乃至整个魔法世界，都与提瓦特的元素法则暗合。
当终局之战降临，七神虚影在霍格沃茨上空浮现，风神卷走食死徒、岩神撑起护城盾、雷神斩断黑魔法……莱恩纳德与赫敏站在七芒星中央，用元素共鸣编织两个世界的命运——原来，早在千年之前，七神的权柄便已埋下守护
