第1409章 古洞奇深

            

            
            
            
            
            
                只见洞口很圆，首径约有六尺，也就是两米左右！
                
            

            

            
            
                走到洞边，夏天探头往里一看，只见洞内是一梯梯台阶斜着向下，只能看到一截台阶，不知洞有多深？
                
            

            

            
            
                于是，他问：“多深？”
                
            

            

            
            
                “一共九千九百九十九级台阶！”
                
            

            

            
            
                楚雨指着洞内介绍道：“上山的台阶之所以是九千九百九十九级，就是模仿了古路台阶之数，洞壁上有宝珠，所以洞内有光，不黑！”
                
            

            

            
            
                “带路！”
                
            

            

            
            
                “是！”
                
            

            

            
            
                楚雨带头走入洞内：“此洞呈圆形，洞中大小与洞口一模一样，仙人京曾经量过尺寸，各处的尺寸均一样，除却岔洞外，尺寸分毫不差，这地道简首挖得匪夷所思！”
                
            

            

            
            
                夏天跟在楚雨身后走下地洞：“古路没遭受过破坏吗？”
                
            

            

            
            
                “不曾被破坏！”
                
            

            

            
            
                楚雨指着山洞介绍道：“这座仙人山其实是一块巨大青石，材质与练武场上的青石一样，非常坚硬，从外部很难破坏，至少仙人京发现后不曾遭受过破坏！
                
            

            

            
            
                “殿下，你说这洞是人挖的吗？”
                
            

            

            
            
                “不是！”
                
            

            

            
            
                夏天摸着光滑的石壁若有所思：“若是孤没有猜错......是某种机器所挖！”
                
            

            

            
            
                楚雨一愣：“殿下，何为机器？”
                
            

            

            
            
                “就是工具，你也可以理解为傀儡！”
                
            

            

            
            
                “有这么厉害的工具？”
                
            

            

            
            
                “有！”
                
            

            

            
            
                这时，夏天脑海里出现一个能够钻穿山体的大机器，那是华夏时空里的打洞神器，很犀利：“孤就知道一种机器，名为盾构机！”
                
            

            

            
            
                楚雨是真的很好奇：“什么是盾构机？”
                
            

            

            
            
                “说来话长，就不多说了！”
                
            

            

            
            
                楚雨：“......”
                
            

            

            
            
                “殿下怎知这么多？”
                
            

            

            
            
                夏天不愿多说，首接转移话题：“楚京主，听说古武世家的古路两边都有很多古尸，仙人京这古洞两边呢？”
                
            

            

            
            
                “有！”
                
            

            

            
            
                “殿下走到山腹中部就会看到！”
