修仙界的矿工可完全是一门苦力活。矿石深埋地下，凡人用普通的锄头，铁铲，根本挖不了。修士必须使用特殊的灵铲，灵镐，灵锄等(简易灵器)才能分离晶矿。矿的种类有数百上千种，当然常见的修仙矿石有灵石，铁精，银精，铜精等炼器材料的矿石。
据说修真水平更高的大明本部，修仙者可以借用傀儡术来挖矿。挖矿的效率更高，这样修士们的时间就可以用来修炼。而修真水平相对落后的越州修士们还是采取落后的灵铲，灵镐来挖矿。
赵恒分配到的矿井是距离云霞宗百里的一处火灵石矿脉。这里也在青霞山脉范围。赵恒发现每挖一下都会往灵铲注入少许灵气。刚开始每天都挖不了几铲就因为灵气耗尽而作罢。后来修为进入炼气期一层情况才稍微转好。
宗门要求每个矿工都需要交一定数量的晶石。想偷偷使用灵石修炼是不可能的，有执法队的巡逻监视。再说每天的任务量都可以把矿工们压死。偷拿灵石更不可能，矿工们不允许配带储物袋矿井，他们也穷得不可能有储物袋这种‘高级货’。
已经过了半年了，赵恒完成每天的挖矿任务后剩余的时间全部用来修炼。可还是在炼气期一层原地踏步。可每天只有三四个小时的修炼时间何时才能修炼到炼气二层。
赵恒从那本《梦溪笔录》了解到，修仙者想要提高修为即使是天才也必须花费大量的时间打坐修炼。在同样的灵气浓郁程度资质好的修仙者吸纳的天地灵气速度是资质差的修仙者的数倍。比如天灵根是双灵根的两倍有余。单灵根吸纳的灵气速度三灵根的四倍，是四灵根的8倍，至于五行灵根吸纳的速度只有天灵根的十六份之一。
可想而知修仙者的资质好坏也差不多决定了前途。除非灵根属性不好的修仙者有大量的资源支持，能到灵气更加充沛的环境，或者服食大量的丹药。可是修仙门派当然把资源倾斜于灵根资质好的修仙者。好的灵脉和丹药，灵石优先供给精英弟子。
赵恒每天挖着火灵石，大把的修仙资源却不能使用，全部上交给宗门。如果每天挖到的数百火灵石，自己能吸纳，别说炼气期二层，就算筑基期也指日可待。看着这些诱人的火灵石，赵恒无奈的摇摇头。偷拿灵石的矿工轻则废修为，重的话被处死。这条规则可是云霞宗的不可跨越的红线。曾经有不信邪的矿工偷藏晶石，结果被执法队查到，当场处死。也有矿工在矿井偷偷拿灵石修炼，结果被执法队撞到被废去修为。修仙者被废了修为此生再不可能踏入修仙界。
好在矿工的辛苦大家有目共睹，每个月分配到的灵石倒是比在宗派内轻松杂役，看门，种灵草之类的多一倍。足足拿到每月四枚低阶灵石，如果挖到高阶灵石，宗门的赏赐更多。能吃的了苦头的低阶弟子还是愿意挖矿，无他，报酬多。
这半年来赵恒积攒了十来枚低阶灵石，大部分是火灵石，灵石是宝贵东西。听门内的师兄弟说灵石除了打坐修炼，恢复法力，布置阵法外还可以用来当做货币交易，如同世俗界的金银货币。赵恒发现吸纳了几次灵石后，修为根本没有进步，只是把体内消失的法力补满而已。如此赵恒打算拿灵石换取一些丹药，据说修仙者想突破修为更多是依赖丹药。
这天，赵恒抽空到云霞宗的唯一坊市。用十枚低阶灵石换取了5粒固本培元丹。回到自己的屋子服食丹药，赵恒先是服食一粒固本培元丹，然后打坐修炼，引导灵气冲关，当赵恒感觉灵气不够时，又服食一粒丹药，如此一个晚上服食了五粒丹药。赵恒感觉自己的体内灵气充沛，隐隐有突破炼气期二层的冲动。一个时辰后赵恒停止了修炼，虽然还是没有进入炼气期二层，但是给赵恒一个希望。
半年的积攒一个晚上花完。这让赵恒不禁有点肉疼，修仙者多少资源都是不够花的。这也让赵恒有了一个明确概念，只要拥有足够的丹药和灵气，即使自己的灵根资质低下还是可以正常修仙。
可是按照目前做矿工换取报酬，每个月的四枚低阶灵石，可以换取两粒固本培元丹。自己一年后才可能突破炼气期二层，三年炼气期三层。修仙越往上越难，如果四十岁之前不能筑基，那此生大道难成。修仙者也是与时间赛跑，多数修士将大量的时间投入修炼，期待不断的提高修为。
挖矿非常辛苦，而且耗费大量的宝贵时间，为宗门做贡献，帮别人做嫁衣。自己的报酬非常低，根本没法满足修炼。想到这些赵恒无奈的摇摇头。还得努力提高修为啊！只要修为提高到炼气期四层，也就是炼气中期，就可以自由的接一些宗门发布的任务。这些任务有难有易，报酬也相应的相差很大。有的任务可能得到上千灵石，有的任务可能只得几颗低阶灵石。
