One point for special effects and two points for the end. Okay, I know it's a commercial movie, but many diving problems must at least conform to the basic logic.
Diver said that it was unbelievable, 5 meters straight down to 47 meters, even for OW it is very easy to burst the eardrums, not to mention the two girls without any training. Of course, if the eardrum bursts, it will not die. In the pain and panic, 100 Qi can last for ten minutes. And what the brothers on the ship did is even more puzzling. Isn’t the first priority not to throw the gas cylinders first? Nitrogen drunk, decompression sickness, they all stepped aside when they were almost out of breath. In addition, without wearing a diving suit of at least 5mm thickness, hypothermia will occur if you stay at a depth of 47 meters for 10 minutes. I once dived to 42 meters in the extremely warm waters of the Caribbean Sea. After 3 minutes, I couldn't stand the cold and returned to 20 meters, which is really a temperature of one meter. Ahem, I know the director wants us to look at our legs.
Two points at the end, everything underwater is an illusion, well, that makes sense.
