Two Wan Li under the sea suffer from the lack of oxygen in Antarctica. "Two Wan Li under the sea" suffered from severe hypoxia in Antarctica. When the submarine sailed to the South Pole, an iceberg capsized and hit the submarine. The submarine couldn't find a way out for a while and fell into the dilemma of iceberg road closure. Their ship is frozen under the ice, and the crew is in danger of being crushed or suffocated. Captain Nemo encouraged everyone and tried his best to get them out of danger. They take turns to chisel the ice sheet at the bottom of 10 meter thick with pickaxes and crush it.

The scene of two Wan Li at the bottom of the Antarctic is that Nautilus intends to float to the surface for air when it arrives at the South Pole. Who knows that their roads are frozen and they can't breathe air. Although Nautilus is very advanced, it has already opened two Wan Li at the bottom of the sea and can't make oxygen by itself. They can't live without oxygen. They hit the ice with their horns and cut the ice with their picks, but when they cut the ice, the ice keeps thickening. Later, the ice became thicker and thicker.
