You can actually hear the person talking, and unlike TV that has very short clips, radio news usually has longer segments, so I am a big fan of that.

你可以听到人们的谈话，不像电视新闻都是很短的片段，广播新闻通常报道时间更长，所以我是广播新闻的拥趸。

So to finish the wall in time, you need the longest segment that can't be destroyed by any combination of the siege weapons, which your enemies have hundreds of.

所以要及时完成城墙，你需要最长的一段，它不能被任何攻城武器的组合摧毁，你的敌人有数百种。
