In 1868, the rumors of a sea monster attacking a ship in the Pacific Ocean caused anxiety and fear among sailors and destroyed the waterway.
After months of searching, the sea monster was found. Although the battleship fired at it with cannons, the sea monster still slammed into it. Aronas and Ned Lan fell off the ship, and Consel also jumped off after Aronas. The burning battleship looked helpless. It drifted quietly. When the passengers under the ship yelled for help, no one on the ship answered. The three men wandered in the sea and finally found a strange-looking metal ship. They realized that the sea monster was a man-made, empty submarine. Inside, Aronas found a viewing window and saw the underwater funeral.
The crew of the submarine returned to their ship and captured the victims. The captain introduced him as Nemo, the owner of the Nautilus. He returned Ned Lan and Consel to the deck, but out of appreciation for Aronas' work and research, he was willing to give him the opportunity to stay. When Nemo decided that Aronas would die with his companions, he allowed Ned Lan and Consel to come on the Nautilus.
Nemo took Alonas to Ponti Island, a criminal exile in the United Kingdom (according to the original work, Nemo is an Indian and should be invaded by the British). Nemo revealed that he used to be a prisoner here, including all his crew. The prisoner was carrying an ammunition ship. The Nautilus struck the warship, destroyed its cargo, and killed the crew. The painful Nemo told Aronas that his behavior was to save thousands of people who died in the war. He also revealed that this "nasty country" tortured his wife and son to death when trying to force him to surrender the secret of the Nautilus. Niederlan discovered the location of Nemo's secret base, the volcanic island, and released the news in a bottle, hoping that someone could find them and get him out of bondage.
On the coast of New Guinea, the Nautilus ran aground on a reef. When Nemo allowed Ned Lan and Consel to go ashore to collect specimens, Ned Lan was very happy. Ned Lan disembarked alone to explore the forest vagina where he had escaped. But when he knelt by the pool to drink water, he saw hundreds of heads on the pile. Aware of the crisis, Ned Lan fled for his life and returned to Conselna, after which the cannibal Manhunt went to the Nautilus.
Although Nemo stayed stranded, he didn't care at all. He used the electric charge to circulate on the hull of the ship to repel the cannibals from the ship. Nemo was furious at Ned Lan's failure to obey his orders and imprisoned him in a submarine cell.
A battleship approached and fired on the Nautilus. The submarine descended into the deep sea and attracted an Octopus . When the Nautilus approached the volcanic island, the island was surrounded by battleships and the army was gathering in his hideout. When Nemo came ashore, Ned Lan tried to show that he was the sender of the bottled message. Aronas was very furious when he knew it, and determined that Nemo would destroy everything he found. Nemo installed explosives in his hideout, but was shot in the back when returning to the Nautilus. After driving the submarine away from the volcanic island at will, Nemo announced that "this is the last dive of the Nautilus." Nemo's crew decided to die with their captain.
Aronas, Consel and Nieder Lan were confined to their cabins. The sailors of the Nautilus also withdrew to their cabin under Nemo's instructions. Ned Lan resisted and tried to make the Nautilus surface, in the process it hit a rock. Nemo staggered to the observation window and glanced at the sea he loved before he died.
Aronas tried to retrieve his diary full of voyages, but the urgency of their escape forced Ned Lan to stun him and transport him out. At the moment of the explosion they witnessed the destruction of the volcanic island. When the "Nautilus" disappeared in the waves, Nemo's last words sounded in Aronas: "The future is always full of hope. When the world is ready to usher in a new and better life, these will become the past."
