ramparts

A mole can undermine the strongest rampart.

一只田鼠能毁坏最坚固堡垒。

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

有一个卫着城堡来回走动。

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，照现形势来，我觉得将来最好是不再需要设我们这城保护员了，那就说明城线人们保护城意识已经到了相当高境界了，人为破坏城现象再也没有了。
