The whole thing involves the strange apparatus in Fei'Yin. Need to do the mini quest with Boisterous Jackal in Lower Jeuno(Across from the Auction House). You'll get directed to the one in Fei'Yin which will then be active. The zone code for Fei'Yin is 23. After you make yourself Administrator, you'll get directed to take your melodies an infinity core and a chip to finish mount synthesis. This is the part where I'm currently stuck, as I haven't tracked down what elemental chip(s) is needed. I get told that a critical failure occurred in decryption happened and it fails, So far I've tried Clear, as well as Clear / Purple / White combo(Given the whole rune fencer storyline) Even farmed up a Cyan chip from Pso'Xja and tried that too. I'll edit / post when I get this last step done. As posted below the chip required is a metal chip from Limbus(Potential drop from end chest / 75 Ancient Beastcoins).
If you're planning on finishing this right away, it might be smart to just buy 75 ABCs now while they're available. I really didn't want to farm the chip myself, so I grabbed some ABCs from a bazaar.
You need to pick a zone after talking to him and do the Doctor status thing for that zone. Once you do that and go back to him, he'll mention that the strange apparatus in Fei'Yin has started working.
