In this situation, he only had one method to resolve the matter, which was to actively draw the Alliance's attention. As long as he could achieve this, joining the Alliance would be settled.
Put more bluntly, he needed the Alliance to remember he existed and, preferably, to regard him with a certain level of importance. That way, his accession to the Alliance would be secured; after all, due to Wilton's reason, the Alliance had already agreed to his joining, and the path ahead was paved.
The reason why Rocky had summoned everyone today was exactly for this matter.
Previously, because he did not know what Lexington had done, he could only wait when it came to the Sky Alliance, unable to do anything.
But now it was different. Now that he knew the ins and outs of the situation, he could come up with targeted solutions or even take the initiative to strike.
