ramparts

A mole can undermine the strongest rampart.

一只田鼠能毁坏最坚固的垒。

There is guard toing-and-froing along the rampart.

有一个卫兵在沿来回走动。

It seems unnecessary to have watchmen like me on the Wall in the future when people along the Wall know better than to further vandalize the rampart.

不过，照现在的形势来，觉得将来最好是不再需要设样的长保护员了，那就说明长沿线的人保护长的意识已经到了相当高的境界了，人为破坏长的现象再也没有了。
