会欲速则不达。
在视察铁矿洞时，他从负责劳改营的守卫口中得知，劳改营的俘虏干活倒也卖力，便找了几人细问了下情况。从劳改犯的口中他得知，万家坪的山匪倒像是个等级森严的奴隶社会，财物全归首领熊犇所有。除了山匪头目和熊犇的亲兵队能做到吃香喝辣的外，其余山匪也是要劳动的，大部分山匪整日从事劳作也是只能混个饱食而已。至于山匪中体弱不能打仗的人生活更是凄苦，平日根本不能吃饱，还要随时挨打受骂。这些劳改犯在矿洞里做工，除了劳动强度大和没有自由外，饮食倒与当山匪时差不多，偶尔还能吃上肉。而且听说工作量超额还能减刑期，当然干劲十足。
在各个建设工地和矿洞中，欧阳轩到的最多地方还是新建好的炼钢高炉和铁匠铺。其实在北宋时期，江南地区便有了类似的现代土法炼钢的高炉，建造这种结构简单土高炉只需耐火砖，也只需要生铁和木炭便可炼制出钢铁，其建造和运营的难度其实并不大。当然这种土法炼钢技术在这个时代，仍属于高精尖技术，掌握的地方并不多，欧阳轩也是花了很多时间精力在这上面。当然相比炼钢炉，他花在铁匠铺上的时间更多。在铁匠铺突击打造了一批长矛和折叠盾牌后，欧阳轩要求除了铸造手雷外壳外，下一步重点则是准备铸造铁炮。
其实欧阳轩也知道在当前的冶金水平下，先铸造铜炮才是最佳选择，因为铜的熔点低延展性好，方便铸造且不易炸膛，但铜料缺乏让他不得不铸造铁炮。两宋由于疆域远比汉唐小，境内的铜矿资源缺乏，所开采出铜甚至不够官方铸铜钱之用。四川尤其缺乏铜矿，离得最近的大型铜矿远在云南境内——现在尚是大理国。因为铜钱极度缺乏，朝廷特许川峡四路铸造铁钱用于流通，也正因为笨重的铁钱不适应发达商品经济的发展，四川才诞生了世界上最早的纸币——交子。至于用铁铸炮是否会炸膛的问题，欧阳轩倒不怎么担心，毕竟抗日战争时期的民兵游击队，还用过松树做土炮。当然他对预防火炮炸膛也提前做了应对手段。首先是将铁精炼成钢，并在铸造时加厚管壁；其次是在炮管外边加上几道铁箍增加牢固性；三是减少装药量，这虽然会对射程和威力变弱，轰击坚固堡垒会力不从心，但要用于轰击人体这种软目标是足够了的。即便山匪穿上铁甲，也经不得一炮轰击。
这几日欧阳轩泡在铁匠铺里，指导李三儿制作了一大一小的两门炮模，他准备等第一炉钢水出来后，便浇铸试制前膛炮。欧阳轩曾在铸造前膛炮还是更先进的后膛炮上犹豫了许久。相对前膛炮，后膛火炮虽然装填方便且射速快，但铸造难度相对较大，如果密封性解决不好则会膛压不足，威力会比前膛炮小许多。当前防守琉璃坝是重中之重，欧阳思量再三，决定循序渐进先从简单开始，先铸造技术含量低的后膛炮。等以后打败山匪准备往山外发展时，再铸造更先进如佛郎机等后膛炮。
