After transforming into submarine mode, the Prosperity quickly submerged into the sea.
Noah also temporarily used the power of the Float-Float Fruit to clear away the silt from the surrounding seabed.
Without lingering, the group headed straight for the core area of the ruins—the region where gold and silver jewelry reacted most strongly to the electromagnetic field. Such areas are usually the core of a civilization.
Sure enough, after Noah cleared away a patch of mud, a sacrificial temple and a large complex of castle and palace buildings appeared before them.
Robin, who had come through the wormhole, now conjured up a large number of eyes, observing the patterns, texts, and reliefs on these buildings.
She quickly discovered information that confirmed the identity of the ruins. "These are the ruins of the Quebo Kingdom, once a world-renowned center of wood carving and artifacts."
"This statue represents the forest god they worship." Robin's clone was in the temple, holding a small submersible containing a specially made Den Den Mushi.
"This statue is still made of Adam Wood, but it's a bit small; it can only be used to build a small sailboat."
Although it was a bit small, Robin didn't waste it. He immediately threw out a Magic Card [Storage Box] to seal away the statues, reliefs, and stone slabs in the temple.
After looting the entire temple, Robin's clone continued swimming towards the kingdom's palace.
Due to the corrosive effects of seawater, the pressure of silt, and the activity of marine life, many palaces in the royal palace collapsed.
You can even see many intelligent marine creatures that have made this place their nest.
Noah did not kill them, but instead used Conqueror's Haki to temporarily drive them away.
Robin's clone examined the various relics within the palace ruins.
Suddenly she discovered that a large amount of fruit was stored in an abandoned refrigerator in one of the rooms, clearly indicating that the sea monster had used the abandoned refrigerator as a food storage box.
"Huh? What's this?" Among a pile of fruit, she spotted a bright green honeydew melon covered in arabesque patterns. "It's a Devil Fruit, and it looks familiar!"
Inside the ship's cabin, Noah was suddenly overwhelmed by memories deep within his mind: 'This fruit is the one he encountered in the Hachi story's cover story; so this is the ruin he passed through.'
Robin quickly brought the Devil Fruit back.
By consulting the " Book of Devils," it was confirmed that this fruit is Paramecia Tree-Tree Fruit.
" Tree-Tree Fruit? A lower-level version of the Woods-Woods Fruit?" Noah guessed. According to the information he had gathered, all previous Devil Fruit User had a creation-type ability, and none of them had superhuman abilities.
The user of this fruit can create all sorts of wood, woodenware, and wood carvings; these wooden products require the user to maintain them.
To create permanent wooden products or trees, one must use natural trees or use tree species that have been artificially induced to grow.
Noah did not immediately make a decision regarding the arrangement of the fruit.
On one hand, among the core members of the family, only Penguin, Shachi, Bepo, Law's mother and sister remain who haven't eaten Devil Fruit, so this fruit isn't suitable for them.
On the other hand, the Tree-Tree Fruit are not suitable for being transformed into Apostle of the Major Arcana Deck, and transforming them into Apostle of the Minor Arcana Deck would be a waste of their potential.
Therefore, Noah decided to temporarily seal away the Tree-Tree Fruit.
Meanwhile, Robin's clone, who was still exploring the ruins, received Noah's instructions to collect some extinct tree materials during the exploration.
After all, these ancient trees can be replicated or even re-cultivated using their Tree-Tree Fruit.
Perhaps among these ancient trees, there are some species with special functions.
After all, there are some peculiar trees in the world of One Piece.
Examples include the Treasure Tree Adam, the mangroves of the Sabaody Archipelago, and the Sunlight Tree Eve on Fish-Man Island.
Like Robin's Flower-Flower Fruit, she can develop various organ-derived abilities by using organs to bloom; she can also develop various natural flower abilities by using flowers that exist in nature.
Three days later.
Robin has finally completed the initial exploration of the ruins of the Quebo Kingdom, not only collecting a large number of ancient wooden artifacts but also obtaining a great deal of information about the Quebo Kingdom.
Among them, the most valuable items were more than a dozen rock paintings.
The reliefs on these rock walls depict the neighboring countries and uninhabited islands surrounding the Quebo Kingdom.
By comparing the sea map of the East Blue Calm Belt Sea with the Noah Family's internal map, we can find 16 kingdom islands and 73 uninhabited islands involved in the rock paintings of the Quebo Kingdom.
At this time, 13 islands containing kingdoms had completely sunk to the bottom of the sea. Of the remaining 3 kingdom islands, 2 had become primeval forests, and 1 still had a small number of tribes.
Noah was not surprised by this result.
After all, the moment the Calm Belt formed, it meant that these islands became truly isolated, and with rising sea levels submerging most of the plains, the remaining population could only eke out a living on the isolated islands.
In recent years, as the World Government has gradually entered the Calm Belt using the Seastone aura simulation technology developed by Vegapunk, it has exterminated a portion of the barely surviving indigenous people.
The only remaining indigenous island in the nearby seas was actually quite lucky, because a few years ago they happened to encounter the Noah Family's secret mapping of the Calm Belt seas, and were thus brought under the rule of the Kingdom of Dawn. Now they have all immigrated to the Paradise Sky Island Governor's District.
The Noah Family has investigated and found no fewer than fifty islands inhabited by natives of the Calm Belt who were secretly exterminated by the World Government.
This is only considering the fact that the Noah Family secretly relocated some of the original inhabitants from the islands in recent years; otherwise, the number would be much greater.
A large portion of the World Government and navy truly deserve descriptions such as heinous crimes and countless evil deeds.
After obtaining these ancient maps, Noah selected two of the more valuable kingdoms to explore along his route.
These two Ancient Kingdom were the Euclid Kingdom and the Gauss Kingdom.
According to fragments Robin obtained from the Ohara Library, the Euclid Kingdom was a nation famous for alchemy, while the Gauss Kingdom was known for its automata.
Clearly, both countries possess their own unique technologies.
While the ruins may not necessarily preserve the complete technology, they can at least serve as a reference.
After all, the Noah Family still possesses many technologies left behind by the lunar civilization. When the Moon People returned to Blue Planet, they also had technological exchanges with intelligent races in various parts of Blue Planet. Whether these exchanges were proactive or reactive, at least some of the Moon People technology and Blue Planet's native technology were integrated.
The kingdoms of the Euclid Kingdom and Gauss Kingdom, as the most technologically advanced powers among the native civilizations of Blue Planet at the time, must have known about the Moon People's Kingdom of Gods and the Great Kingdom of Joy Boy.
Therefore, Noah believed that the ruins of these two kingdoms were worth exploring.
Two days later.
The Prosperity arrived at the underwater ruins of the Gauss Kingdom, the Kingdom of Puppets.
However, Noah, standing on the deck, showed a hint of surprise on his face.
He discovered that the ruins of the Gauss Kingdom on the seabed contained a large number of moving puppets, which were still functioning.
