Was there any relationship between the three works of Verne's trilogy?

Whether the three works of Verne's trilogy were related could be explained by the following explanation: Verne's trilogy referred to the three series of novels written by Verne, including The Earth Explorer (The Woodman), The Ocean Explorer (The Children of Captain Grant), and The Centauri Decision. These three works were closely related because Verne showed adventure stories in different fields through their perspectives. The first movie, Earth Explorer, told the story of human adventures in space, including the discovery of a mysterious civilization on a planet in outer space. The second book, The Wood Man, was about a scientist and a mysterious monster, who was thought to be one of the oldest and smartest creatures on Earth. The third book, Ocean Explorer, was about a series of adventures that humans took to explore the ocean, including the discovery of a mysterious civilization at the bottom of the sea and an underwater war. Therefore, these three works were both connected and independent, which together constituted Verne's adventure series.
