Captain Nemo collected gold and silver treasures at the bottom of the sea to support the just struggle of the oppressed nations. When the motherland became a colony, he led several like-minded people to dive into the seabed, propping up and awakening the struggle of the oppressed nations against colonial rule with rebellious actions and dissatisfied remarks.

Captain Nemo seems to be a lonely hermit with a dying heart.

But his strong inner feelings show that he is a scientific soldier who always pays attention to the world political situation.
