Strangulation, as an innate Codeless, supposedly had difficulty even boarding an airship, let alone transferring between them. As a Codeless, he might have been detained at Sun Island or God Communication Island.
He was able to travel normally because he had inserted a "Fake Recognition Chip." This was provided by the Director of Amirus, manufactured with the authority of the Elf Director, and was able to perfectly imitate a set of complete personal information. However, if connected to the information database, it could not be found or traced, and it was completely impossible to invade — it was a "temporary external chip."
He possessed the most core function of the chip — the crucial personal identity code, account head, payment and charging capabilities, and the ability to look up information online. And as a recognized "citizen"... that was the most important part.
