城东，一栋外表普通、内部却经过特殊改造的旧式筒子楼顶层，成了林涛临时的“实验室”与“安全屋”。
这里原本是苏家一处极隐秘的产业，安保级别极高，内外多层防护，且与外界彻底隔绝。
搬进来时，林涛只带了必需的几件衣物、沈师傅的笔记和日记、那卷残谱，以及轩轩寸步不离的小恐龙玩偶。
至于“万家灯火”的日常经营，他全权交给了小刘和提拔起来的副手，自己只通过加密渠道进行远程遥控。
轩轩在医院观察两天后，也被秘密转移到了这里。
孩子虽然不再发烧，但精神状态依旧不佳，夜里时常惊醒，需要林涛紧紧抱着才能重新入睡。
林涛将巨大的悲痛与怒火压在心底，在儿子面前只展现无限的温柔与耐心，但当他独自走进那间被改造成厨房兼工作间的房间时，眼神便只剩下冰封的决绝与专注。
残谱上的“九转玲珑丹”，成了他所有心血的聚焦点。
他不再试图完全复原这道虚无缥缈的“古菜”，而是将沈师傅日记中的零星线索、笔记里关于“药膳”与“形意”的论述，以及自己对传统烹饪和药材药性的理解，全部杂糅在一起，进行一场大胆的、危险的“创作”。
他要“创造”出一种看起来古意盎然、工序繁复、用料珍稀、似乎蕴含着某种“特殊功效”暗示，但在关键步骤和最终“功效”上留有明显破绽和疑问的“半成品”。
过程极其艰难。
许多古籍中记载的所谓“珍稀药材”，如今要么绝迹，要么有严格的管制。
他不得不用性质相近、但价值与神秘感大打折扣的替代品，并刻意在炮制手法上留下“古法今用”的不协调感。
火候的掌控更是微妙，既要做出“历经九转”的繁复表象，又不能让成品真正达到某种理论上的“完美”状态。
他将自己关在弥漫着草药与食材混合气味的房间里，废寝忘食。
失败了一次又一次，熬干了数锅汤汁，浪费了无数珍稀食材。
但每一次失败，都让他对残谱背后的意图，对沈师傅日记中那悲愤的控诉，有了更深一层的理解。
这所谓的“丹”，或许从来就不是为了“食”或“补”，而是一种象征，一种媒介，一种用于特定场合、满足特定心理或利益需求的“道具”。
几天后，一个勉强成型的“作品”诞生了。
那是几枚鸽子蛋大小、色泽暗红、表面有着不规则螺旋纹路的圆球，散发着奇异而复杂的香气，混合了药香、蜜香和一种难以形容的、略带腥气的味道。
它们被盛放在一个仿古的玉色瓷盘中，旁边点缀着几片经过特殊处理的、形似灵芝的菌菇薄片。
看上去，的确有几分古籍中描述的“丹”的形貌，但又总让人觉得哪里不对劲，少了些“灵气”，多了些“匠气”和刻意。
林涛看着盘中这几枚耗费心血、实则似是而非的“九转玲珑丹”，嘴角勾起一丝冰冷的弧度。
他要的，就是这种效果——足够引起柯震的兴趣，却又经不起真正行家的深度推敲，更重要的是，留有足够的话柄和疑问，让他可以“请教”和“试探”。
就在他准备联系葛明辉，安排下一次“汇报”时，苏晚晴带来了关于那张黑白照片的调查进展。
她的脸色异常凝重，甚至带着一丝罕见的惊疑。
“查到了。”苏晚晴将一份薄薄的、没有任何标识的档案袋放在桌上，声音压得很低，“但结果……比我们预想的更复杂。”
林涛心中一紧，打开档案袋。
里面是几张模糊的旧档案复印件和一份手写的分析报告。
照片上那个站在沈师傅身边的年轻男人，身份被初步锁定为：陆秉坤。
“陆秉坤？”林涛念着这个陌生的名字。请求出错，状态码:504内容:<!DOCTYPE html>
