On DaiVoyager, the other four were still waiting, impatiently, for news from their friends.

"Should Sakura-tachi not have returned by now?" Natsuki wondered.

"Depends." Souta answered, "If it was just a machine that the Atlanteans, or someone else, had left behind, there would be nothing for them to look for, but if it's Atlantis... who knows what treasure or Precious they find there."

"In which case they'll be good for hours. Days maybe." Masumi sounded angry, "Hours of discovering all of Atlantis' treasure."

Eiji remained quiet, but not because he had nothing to say about this. He saw something, not too far away from DaiVoyager. He wasn't sure of what he saw. He thought it was a whale, except that it was much too big for a whale. An island? Eiji rubbed his eyes, just to be sure he wasn't seeing things. When he looked again, it was gone. Either he was just seeing things, or he did actually see an island disappear within the blink of an eye. In other words, it's too big to be a whale, and too mobile to be an island, then what did he just see?

After a while, Boukenred and Boukenpink arrived at what looked like a machine-room. While it appeared as though it hadn't been used in years, it had this look that would suggest as though this was made hundreds of years in the future, rather than so many years in the past. In either case, Boukenpink used her Accellular to scan the area.

"Hazard level 75... 48... 27..." Boukenpink picked up too many things, "Either my Accellular is going nuts..."

"Or there's more than one Precious in here." Boukenred decided, "If this is what gave this city it's power, it's not that improbable."

"There's a lot of noise here." Boukenpink noticed, "The moment we enter this room, we'll have to shout to each other in order to be heard."

"In that case..." Boukenred suggested, "... I better check up on Emerald first. In case he tries to contact us while we're in."

Boukenpink understood this: "Alright."

"Emerald, you found anything?" he asked him.

"You can say that again." Boukemerald replied over the phone, "There are some very interesting texts and drawings they have here. Their entire history, their discoveries... too bad most of it is too technical for me to understand."

"Wait. You can read some of that?" Boukenpink sounded surprised.

"I know, it's curious, really." Boukemerald explained to her, "Many of these symbols I recognize from Egyptian and Mayan hieroglyphs, and the words they're supposed to represent sound a lot like ancient German, Chinese, Roman, even Native American."

"What are you saying? All of the Earth's languages are used to form their language?" Boukenred needed some clarity on that.

"Yeah." Boukemerald replied, "Too bad I don't know enough Native American to understand this."

"There's a language you don't know?" Boukenpink laughed.

"It makes sense, though." Boukemerald started, "There are so many human tribes, each and every one of them developed their own way of communicating. But for some reason, nearly all human tribes use verbal communication."

"You saying the Atlanteans taught them?" Boukenred suggested.

"Possible." Boukemerald answered, "They all learned their language, or some bit of it, and the rest was independently developed."

"But why would they start teaching them, but not finish it?" Boukenpink wondered.

"Maybe that's when the island sank." Boukenred suggested.

"It still doesn't fit." Boukenpink stated, "If that is why, then why did the survivors not keep teaching them? Why did they let them go and spread all over the world?"

"An interesting point." Boukemerald agreed.

"Alright." Boukenred decided, "Emerald, you keep searching. Pink and I will be in a very noisy room, so we may not hear you if you try to contact us."

"Understood." Boukemerald acknowledged.
