So, war had broken out.
However, for a very primitive tribal civilization, they were the ones who were overwhelmed. Even with strong physical constitutions, it was difficult to contend with the battle-hardened warriors of the Alliance, and that's not to mention the high-tech weapons in the hands of the Alliance warriors.
Lasers are much more useful than stone spears and stone axes.
Then, under the oppression of a survival crisis, the remaining primitive tribes united, and in an extremely short amount of time learned to "read the situation" and wanted to coexist peacefully with the Alliance.
However, communication was a huge problem.
Because the arrival on Qu Bo Star was a direct descent by a member of the Alliance, not through the Taixu Illusory Realm, there was no language translation or telepathic communication, so they needed to learn each other's languages.
