金气腰扣的钛丝在锁内第三次折断.
徐时（晚上 7 点至 9 点）的行刑场散发着骨粉的气味——白天因疲惫而死去的徭役工人被石磨成灰烬,混入江堤填土.林天宇的腕骨在玄铁锁环上流血.断掉的电线卡在了内弹簧的死心处,就像深圳湾崩塌时的那根该死的钢筋一样.
"休息,"行刑柱后面传来一声嘶哑的喃喃自语.瘸子阿朱蜷缩在泥堆后面,啃着野草根,锁骨箭伤上覆盖着黑色的结痂:"张世郎（张副部长）的狗在看着你.
话还没说完,鞭风就来了.骑兵军官的黑色马靴将阿竹的头压入泥泞:"林妖的同伙?靴底将草屑磨碎到男孩的鼻子和嘴巴里.当骑兵军官用锤子敲向阿朱仅存的半个脚趾时,林天宇只看到男孩在泥地上挣扎着划出的划痕——三个平行排列的深槽,直接指向他的锁链挂着的地方.
转眼间,工程师的大脑已经分析了划痕:指骨划痕深度 12 毫米...摩擦系数 0.7...力方向与重力之间的夹角 23°...这是来自原身,一位失败的学者——"数学艺术九章"中的"勾孤太阳观察术"的记忆礼物!
锁舌咔嚓一声咔嚓一声,夹杂着阿朱的尖叫声.林天宇手腕上的铁环突然松动了!骑兵军官转过头的那一刻,行刑柱链如鞭子般扫出——铸钢链打碎了马靴的胫骨,第二击直接砸碎了对方的胸甲.
"走!"林天宇拖着阿竹向河岸走去.夜雾中,数十枚火箭已经钉在了他们踩过的泥路上,在他们身后,骑兵军官尖锐的哨声响起:"逃跑的人要杀——!
湍急的水流令人毛骨悚然.两人躲在竹子加固层的水下缝隙中,腐烂的竹纤维拂过他们的脸颊,浑浊的海浪."堤坝撑不到天亮,"林天宇撕开衣服,把阿竹断的脚趾紧紧地绑住.水倒映着远处工棚的篝火,骑兵队正拿着滴水的长矛巡逻.
"那是...盐袋?阿朱突然抓住了他的手臂.在 30 丈（约 100 米）外的码头上,苦力正在向芦苇棚卸麻袋.洁白的雪花般的颗粒从破损的袋口中渗出,在月光下散发出不祥的寂静——没有潮解!纯结晶氯化钠?这种纯度可以打败清朝的扶石井!
记忆碎片砸向林天宇:张世郎轿子图纸上的朱红色叙述——竹材加固价格涨了三倍...谎报银两下落...
"为什么盐运输要经过江堤水站?"他盯着卸货工人腰牌上的"曹云思"（大运河运输部）黑字,突然一把抓起湿透的葛布,拧干了水.当布料被撕掉一半时,工程师的手在颤抖:"我需要你当诱饵.
紫时三分（晚上 11 点 45 分）,芦苇棚着火了.
随着盐袋爆炸的蓝色火焰飙升到三丈高,林天宇正将葛布裹成套索,潜入江心.在水下,三根绷紧的竹制加固柱子就像颤抖的琴弦——震动来自上游!潮还早!
阿朱的惨叫划破了混乱:"林妖师正在用天火烧堤——!在骑兵军官弩箭追逐的声音中,男孩拖着血淋淋的双脚朝着盐仓的火堆走去.
繁荣!
氯化钠爆炸的冲击波吹落在芦苇屋顶上,从天而降的蓝色火焰就像地狱般的磷蝶.林天宇闭上眼睛,听着阿朱的咆哮淹没在混乱中,绞索突然收紧在他的掌肉里——他正拉着一根长约十尺的水下量尺!
鱼竿浸入水中的深度.差压流量换算机
"徐时水位已超过死线!"他撬开河底的石头缝隙作为杠杆.当刻有墨纹的量尺从水中冲出时,骑兵军官的弩已经锁定在了他的心背上——
在冰冷的霜状月光下,一块灰白色的岩石碎片被吸附在量杆的顶部!
毛小时早些时候（凌晨 5:15）的大坝平台充满了死寂.
张世郎的金气袍被露水浸透成赭色,阿朱发高烧抽搐着,跪在他的脚下."昨晚有二十四名骑兵军官惨死,够你被砍三千刀了!"他用靴尖磨平了少年的箭伤,目光却定格在林天宇手中的量尺上:"锻造河妖水鉴定,不愧是那五匹马..."
"请看,先生,"林天宇掰开了量尺顶部的灰色岩石,"灰色岩石只在水面以上的岩层中形成.今天早上的河雾还没散去,但岩石碎片上却沾满了露水——"他突然将岩石碎片举起,迎着清晨的阳光.在清晨的阳光下,水渍上沉淀出几颗盐霜结晶!
张世郎的喉结晃动:"这是什么意思?
"昨晚爆炸的盐雪渗入河水中,向上涌动.当露水浸湿了附着的墙壁灰色岩石时,盐晶体使石头的缝隙破裂.工程师的指尖在岩石表面描摹着蜘蛛网的图案:"像破冰的石头.但领主知道吗..."
他突然将量尺插入路堤基础的渗水孔中.一层闪闪发光的氯化钠晶体居然漂浮在水面上!
工人们嗡嗡作响,就像蜂巢筑巢一样,林天宇的宣告划破了浓雾:"灰色的岩石剥落证明,水位已经达到了堤顶的保护层——洪水正在凿穿大坝!
"Nonsense!" Zhang Shilang drew his sword and slashed at the measuring rod, but saw Lin Tianyu pull A-zhu's scalding hand and press it into the river.
"This child has had a high fever for four shichen (8 hours), his body temperature is forty-one degrees." Lin Tianyu pressed the boy's palm tightly against the embankment foundation, and white steam instantly evaporated from the turbid flow in his fingers: "Seepage temperature rise of six degrees—the vanguard of the river tide has reached behind the dam!"
In the silence, the lame boy suddenly jumped up and bit Zhang Shilang's python boots! Almost at the same time, a muffled thunder-like bone cracking sound came from deep within the dam.
The breaching of the dam at Chen hour (7-9 AM) was black.
As Lin Tianyu dragged the feverish and dying A-zhu onto the bamboo raft, the crack in the Jiang embankment had devoured people and animals like a monster's giant mouth. In his last vision, Zhang Shilang's gold chi robe was hung on a stone roller and twisted into pieces, and the screams of his entourage were mixed with the roar of the turbid waves: "The salt license is still in the cabin... millions of official silver..."
"Brother..." A-zhu convulsed on the raft, blood foam gushing from his arrow wound, "The salt department's accounts... are in the shack..."
As the boy died, Lin Tianyu's hand sank into the interlayer of his torn cotton jacket. The oil paper-wrapped booklet was soaked in blood, and the first page was a vermilion-drawn transfer map—three waterways converged at the Lanjiang embankment into a scarlet arrow... pointing to the capital's official salt warehouse!
At the moment the bamboo raft crashed into the reef, the engineer clenched the iron cable and jumped onto the riverbank. Behind him, thousands of miles of dikes were collapsing, and thousands of corpses floated like insects. And in the ruins of a collapsed military arsenal on the shore, half of a broken cast iron medicine mill was repeatedly washed by the tide.
The concave grinding chamber of the medicine mill was pierced with a gap by gravel, shaped like a giant cauldron.
As the first ray of sunlight split the lead clouds, Lin Tianyu broke off the handle of the mill wheel. The bronze casting bent into a simple vernier caliper between his calloused fingers, and the serrated notch bit into the edge of the medicine mill's gap to measure—crack length nine cun seven fen (approximately 32 cm)... wall thickness deviation zero point three cun (approximately 1 cm)...
He pressed the blood-soaked salt license booklet into the rust of the grinding chamber.
"How about quenching an anvil with the blood of ten thousand wronged souls?" The engineer raised his head and drank the torrential waves, and the caliper tip carved the first mark on the mill body: "This cauldron—first cast the aiming star of the salt scale!"
The wails of the dead laborers rolled in with the river wind, like the hammering sound of a million-ton hydraulic press forging the initial billet.
