"ΤΠ ΚρμυιΙΙ Οβοηησ ΗΘ..."
"ΠΤ Ο ΟλΔχω Κ ΤΟζνβξ...
The small robot emitted a series of strange sounds.
Robin paused for a moment. "This is very similar to the divine language recorded in the Temple of Birka and the Temple of Angel Island..."
She tried translating the text. "Awaken, We, Master, Robot No. 3593, Salute to you... Do you need to re-enter the language..."
Robin spent more than two hours communicating with several small robots, albeit with some clumsiness, before finally completing the input of the common language.
Noah and his companions also conducted a preliminary exploration of the entire underground ruins.
Noah, who had just returned to the main hall, saw Robin communicating with several small robots. " Robin, can those robots communicate now?"
"That's fine, it's just some less commonly used words that they might not understand."
"I've found some things here too, come and take a look!"
"Oh?"
Robin, accompanied by several small robots, followed Noah to a palace.
Robot No. 3593 introduced the site to the group, "This is a temple. Before the ancient gods left Birka, they left behind some murals."
Enel was looking at the mural.
"Is this a picture of the Moon People traveling to Blue Planet?" Robin took out his notebook and started taking notes on some of the content on the mural.
Noah then asked robot number 3593, "Did you leave behind any manufacturing technology?"
"Yes, it's in the temple's archives room," Robot No. 3593 answered curtly.
"Take me there to have a look."
"God, please come with me."
Soon the group arrived at a statue deep inside the temple, and robot number 3593 pressed a the Sun symbol on the base of the statue.
Suddenly, the statue slowly rose, revealing itself to be an elevator.
Take the elevator down several dozen meters, and you'll arrive at Birka's archives room.
There are a large number of stone slabs on display, engraved with numerous texts and patterns. Noah found the blueprints for the Ark Maxim and the blueprints for a small robot among them.
Robin translated part of the inscription on the stone tablet.
"This part is about the history of Birka... So that's how the Moon People came to be. About 8,600 years ago, Moon People ancestors migrated from Blue Planet to the Moon because a terrible catastrophe occurred on Blue Planet, forcing Moon People to leave..."
"After migrating to the moon, and after approximately six thousand years of development, lunar resources are nearing depletion, forcing the Moon People to once again turn their attention to their former home Blue Planet..."
"In the year 6382 of the Sun Calendar, the outpost exploration team successfully returned to Blue Planet and sent a message indicating that Blue Planet had returned to a habitable state..."
"In the year 6402 of the Sun Calendar, the Sky Island Birka was established. After 10 years of survival testing, no serious maladaptive symptoms were found among the 500 test subjects..."
"In the year 6415 of the Sun Calendar, the headquarters decided to initiate a large-scale migration plan..."
"In the year 6583 of the Sun Calendar, an exploration team entered the vast red continent of Blue Planet and established Kingdom of the Gods on that continent..."
"In the year 6770 of the Sun Calendar, the last inhabitants of the Moon Birka migrated to the Kingdom of the Gods on Blue Planet, Moon Birka City was temporarily sealed off..."
Enel listened to Robin's translation with astonishment in his eyes.
Noah wasn't particularly interested in the so-called history of the Moon People.
After Robin finished recording the history of the Moon People, he turned to the section of the tablet containing technical information that Noah was more interested in.
Besides the blueprints for the Ark Maxim and the robot, the Moon People left behind more than a dozen other technologies, most of which were environmental modification technologies.
Examples include "large-scale oxygen production technology using quartzite as raw material", "artificial the Sun simulation technology", "gravity regulation technology", " Magnetic Field Shield technology", "soil improvement technology", and "water cycle technology".
Of these technologies, the most important is actually " Solar Furnace technology".
" The Solar Furnace?" Noah immediately thought of the Mother Flame created by Vegapunk. This thing was most likely the prototype technology of the Mother Flame.
According to Robin's translation, the Moon People discovered an element called " Subhydrogen " on the moon. By injecting it and deuterium into a furnace with a strong magnetic field, they could continuously generate a huge amount of energy.
In Noah's understanding, the so-called Subhydrogen is most likely helium-3.
After more than 6,000 years of development, the Moon People had consumed most of the moon's Subhydrogen reserves, leading to serious problems with their energy supply and forcing them to return to Blue Planet.
However, according to Noah's understanding, if Subhydrogen is helium-3, then the Moon People obviously wouldn't be able to find much Subhydrogen on Blue Planet.
This also explains why the energy of Uranus's Solar Furnace decreased over time, eventually requiring Vegapunk's Mother Flame as a replacement.
Vegapunk's Mother Flame was likely an improved version of the original Solar Furnace technology, replacing the Subhydrogen element with other elements.
Although the raw materials for the Solar Furnace reaction are difficult to find, the technology still has great value.
After recording the information on these technologies, Noah decided to establish Moon Governorate and make the Moon Birka City the governor's residence.
Given the importance of the Moon Governorate and the massive amount of electricity it requires to maintain and restore power, Noah transferred Joshua from the Storm Archipelago Governorate.
Once Joshua arrived on the Moon Birka, after hearing Noah's instructions, he put all his energy into generating electricity.
Noah also had Jay produce a large number of graphene batteries as backup power for the Moon Birka, to prevent the Moon Birka from shutting down when Joshua was away.
Once fully activated, the Moon Birka has over 50,000 small robots, three robot production lines, and various mechanical production and processing equipment. The technology level of these devices is even more advanced than that of Blue Planet.
Immediately afterwards, Noah traveled to the Rum Kingdom through Ray's wormhole, sealed away some of the Rum Kingdom civilians who had passed the screening using cards, and relocated them to the Moon Birka.
More than 20,000 people were relocated in total.
This population, along with more than 50,000 small robots, allowed Moon Birka to quickly recover its vitality.
After doing all this, Noah did not leave immediately, but went to the far side of the moon and established a brand new secret base.
The reason for going to the far side of the moon is, of course, to avoid the changes in the moon being observed by Blue Planet.
Fortunately, there are also city ruins left by the Moon People on the far side of the moon. Noah only needs to modify these underground city ruins to establish the secret base.
The base established on the far side of the moon was intended to solve the energy supply problem.
The Noah Family will not be able to replicate the Solar Furnace in the short term, but the construction of the moon is urgent, so the issue of energy supply in the early stages needs to be considered.
Noah's solution was to utilize the Sun.
The far side of the moon also experiences day and night, but it's not directly observable from Blue Planet.
Last year, Jay developed graphene the Sun panels with an energy conversion efficiency of about 10%, which can be mass-produced using his Devil Fruit powers.
By laying a large number of graphene the Sun panels, coupled with the energy storage of graphene batteries, a huge amount of energy can be supplied to the base.
Although the moon in the One Piece world has an atmosphere, it is very thin and contains almost no water vapor, which means that there are no clouds on the moon. This environment is very suitable for the Sun generation.
With energy support, the moon's population capacity will quickly recover.
