The seabed, more than 80 meters below the surface.
Although the ruins of the Gauss Kingdom are now covered with coral reefs, seashells, and seaweed, many figurines are still active underground.
Robin's clone entered the interior of one of the buildings.
This is a stone processing area, where a dozen or so figures are carving a huge stone, and there are several rock tracks on one side.
Several of the dolls noticed Robin's arrival and immediately stopped working.
The dolls look about 70-80% like humans, but they seem to have undergone some special modifications to adapt to the underwater environment.
For example, it has many legs and fins, as well as a water jet on its back.
One of the dolls, wearing a red number on its head, floated towards Robin. It looked at Robin for a while before picking up a thin stone slab and writing a passage on it using a special kind of coral as a pen.
Robin read it for a while before he could translate its meaning.
Are you a human from outside?
Robin picked up the coral pen and wrote something down.
[Yes, why are you still active? Hasn't the Gauss Kingdom fallen yet?]
[Honorable guest, please follow me. I will take you to see Lord Hart.]
Robin didn't raise any objections, after all, this body of hers was a clone, so there was no need to worry about the other party causing trouble.
The puppet led the way.
After swimming for about half an hour, in the complex underground passages, Robin estimated that he had gone several hundred meters underground.
Finally, after passing through a gate...
Robin entered a room, and the door slowly closed. Then the surrounding seawater gradually receded, and when the water level dropped to ankle height, a passage opened in the steel wall in front of him.
"ξβμβλ..."
A strange sound echoed in the passageway.
Robin listened for a while before realizing that the other person had asked him to go in.
After passing through the passage, we arrived at a large hall.
An old figure appeared before Robin.
The old man introduced himself listlessly, "Welcome, guest from the outside world. I am Hart, a scientist from the Gauss Kingdom."
Robin replied in Gauss Language, "Mr. Hart, I am Nicole Robin, an archaeologist from the Kingdom of Dawn. Could you please answer some of my questions?"
"Miss Robin, I know what you're going to ask. The Gauss Kingdom has perished; to be precise, the vast majority of the people of Gauss were wiped out in the great tsunami eight hundred years ago."
Hart continued, "I escaped because I was conducting research inside this research facility, becoming one of the few survivors."
"There are other survivors?" Robin, somewhat surprised.
Hart nodded. "Yes, I and my colleagues, along with the others who were still at the base, made a total of 736 survivors. But as time went on, we faced problems with food and energy."
"..."
As Hart recounted the story, Robin finally learned the whole story.
Hart and more than 700 other survivors of the Gauss Kingdom, though they survived, still face a tremendous survival crisis.
Some of them attempted to leave, but while sailing out to sea, they were attacked by Sea Kings, and this group was wiped out.
The remaining group focused on how to survive on the seabed, and the leader of this group was Dr. Hart was standing before us.
Through technological upgrades, they successively manufactured ocean current generators, underwater automatons, and most importantly, artificial hibernation technology.
After multiple attempts to leave were thwarted by Sea Kings, Hart and his companions abandoned the idea and opted instead for a plan to preserve the flame of civilization.
With limited food and energy, if the remaining people continue to marry and have children, the result will be the rapid depletion of resources, leading to a situation where they kill each other.
To prevent such tragedies from occurring, Hart and others established an organization called the " Civilization Continuation Committee," which used cryonics to freeze most people deep within the research base. Only five people could control the puppets outside at any given time through an electronic system to take turns on duty.
However, this rotation system is not without its costs.
Because cryonics can only maximize lifespan when the body is completely frozen; if consciousness is retained, the lifespan extension effect will be greatly reduced.
This is also why Hart appears before Robin in his old age.
After eight hundred years and multiple rotations, the 36 members of the Civilization Continuation Committee, like Hart, are all nearing their physical limits.
Finally, Hart pleaded with Robin, "Miss Robin, if possible, I would like to request that you take the 432 frozen survivors away from this prison. In return, I can give you all the treasures and technology of the Gauss Kingdom."
Noah, who was on the sea, also learned of this.
He had no objection to taking in these survivors of an ancient civilization; even if they had any schemes or tricks, Mary's Observation Haki would expose them.
Three days later.
Mary reviewed all the survivors of the Gauss Kingdom, Robin received all the books of the Gauss Kingdom, and Noah obtained all the technologies he wanted, especially puppet technology.
This puppet technology is actually Blue Planet Earth version of the Moon People's small robots.
However, the puppet technology of the Gauss Kingdom and the robot technology of the Moon People have two differences.
Firstly, the dolls have a digestive system similar to that of living organisms, and can obtain energy by eating organic matter.
Secondly, the dolls are more intelligent; they can even simulate human emotions such as joy, anger, sorrow, and happiness, and can understand some human expressions.
The dolls created using this technology can even execute complex commands and perform tasks that are difficult for ordinary robots to do.
After figuring out Hart and the others' true intentions, Noah decided to accept them as members of the Kingdom of Dawn. He used the power of the Float-Float Fruit to directly dredge Gauss Island from the seabed.
Noah placed Gauss Island in the Paradise Sky Governorate.
Hart and the other 36 members of the Civilization Continuation Committee also received Luo's treatment, since most of them were scientists and therefore worthy of treatment.
Although Hart and others' bodies had undergone repeated thawing and freezing, and were already in a state of near exhaustion, their cellular age was only about fifty or sixty years.
This gave Law the opportunity to treat them. By replenishing their life force with life-giving potions, and with Law's Op-Op Fruit Hart Andy's Sick-Sick Fruit no Mi, they were quickly pulled back from the brink of death, allowing them to continue to shine for the Kingdom of Dawn for another hundred years.
After dealing with the ruins and survivors of the Gauss Kingdom.
Noah and his companions then visited the ruins of the Euclid Kingdom.
However, this site yielded little reward, because the Euclid Kingdom was a small archipelago nation, and after these islands were submerged by the sea, this place became the nest of many medium-sized Sea Kings, riddled with holes.
Faced with this situation, Noah and his group had no choice but to abandon their idea of continuing their exploration. Robin returned to the Sky Empire to continue her work, while the Prosperity headed for the East Blue at full speed.
About five days later, the Prosperity finally left the Calm Belt and entered the southern waters of East Blue China Sea.
The Prosperity sailed toward the nearest Oykot Kingdom.
