When a submarine floats up from the sea, it is just rubbed over by a galloping ship. As a result, the cabin leaks and seawater spews in, causing the submarine to sink to the depth of 40 meters deep. When the communication was interrupted and no one came to the rescue, the personnel inside the boat quickly opened the high pressure gas cylinder valve to inflate and pressurize the inside of the boat to balance the pressure inside and outside the tank. Then people opened the hatches and scrambled to climb out of the hatches and float to the surface. However, only the last cook can escape to death, and everyone else is violent on the spot.
