What should you do if someone falls off a ship during an ocean voyage?
The answer is to make a cold dish of it.
In the vast ocean, when a warship over a hundred meters long is sailing at a speed of several knots, it's not an easy task to stop the ship or turn around.
If it were that nimble, torpedoes wouldn't exist as a weapon.
If someone really falls overboard, they're just gone; there's no way to rescue them.
Naval officers swept away by the Temporal Tide face the same issue.
It's not like being on land, where you have enough time, manpower, and resources for a rescue.
In this era without satellite navigation, the Navy simply can't determine where or when these officers were lost.
The only solution is to rely on the subspace beacon... sorry, wrong story, rely on the beacon lit by the astrologer on the flagship to find their way home.
Wang Yunxiao had experienced this before.
