Welcome to the bottom of the world, Doc. Go any further south you'll fall off the planet.
欢迎来到世界尽头,博士。再往南走一点就会从地球上掉下去。
When you climb a mountain, go up a river,The exciting part is not what you know is there.It's what you don't know. It's what you might find,and it's the same here.
当你登一座山,过一条河的时候,最精彩的部分不会是重复已知,而是发现未知,是你可能会发现什么,在这里也一样.
