Disguised
Under normal circumstances, big clans wouldn't allow translators from other clans to look at the techniques and manuals one had received from foreign races.
However, so far nobody had been able to translate the techniques they had received completely, which meant that the Floating Sky technique's full potential had yet to be unlocked!
Marx Gier was fully aware of this, and he could already tell that the translated Floating sky technique would not only allow every member who practices it to become much faster, but also increase their entire combat prowess.
This increase of strength would prevent other clans from trying to conquer them as well as nullify the threat of getting conquered by the other kingdoms that would join the alliance Jason had proposed.
Other than that, it would allow him to have an additional safety net and the members of his clan would no more try to take over his position as patriarch.
