《封神演义》中有位土行孙,其本领非常大.每到紧急时刻,他总能出人意料地遁地而行,令人拍案叫绝。现在,在炸弹的“家庭”中有一种特殊的炸弹,能像“土行孙”一样钻进地下深处。这种炸弹就是人们常说的钻地弹.普通炸弹在触地的瞬间就会爆炸,但钻地弹却在投到地面时不立即爆炸,而是继续向下钻,当钻到一定深度后,才发生爆炸,从而将地下深处的目标摧毁.一般的钻地弹都能钻透数米厚的水泥地,有的钻地弹甚至能钻到一百多米的地下深处爆炸. There is a place where grandsons can be found in “The Story of God”. His skill is very large. Every time he comes to an emergency, he always unexpectedly rushes to the ground. Now, there is a special kind of bomb in the “Family” of the bomb. It can get into the depths of the ground just like “Soil of the earth.” This kind of bomb is what people often call earth-drilling bombs. Ordinary bombs will explode at the moment of touchdown, but they will not explode immediately when they hit the ground. They will continue to drill down and drill to a certain depth. Only explosions occurred and the targets in the deep underground were destroyed. Normal drills can drill through several meters of concrete, and some of the drills can even reach more than one hundred meters deep underground.
