BLUESPACE fighting the intergalactic war?

I just finished the trilogy via audio book. Let me know if this is a stretch.

When Chung Xi meets up with whats-his-face, and he doesn't talk about World 3 (?). Could it be that the crew of Blue Space have started a world and are attacking the cleanser species? And were they responsible for destroying the Trisolarian homeworld? Because we know the Cleanser race wasn't responsible. Was this what the author was hinting at?

I listened to this all on audiobook. Thanks in advance for reading my post and sharing your thoughts
