Moreover, the moon then disappeared and left us in profound darkness. We had to wait for daylight to find some way of getting inside this underwater boat.

而且这时，月亮又消逝了，我们是在一片深沉的黑暗中。只好等到天亮，才能想法进入这只潜水船的内部。

So our salvation lay totally in the hands of the mysterious helmsmen steering this submersible, and if it made a dive, we were done for!

In fact, if they didn't produce their own air, they inevitably had to make periodic visits to the surface of the ocean to replenish their oxygen supply.
