First, it would use bloody methods to exterminate the weak race alliance.
But it would not be easy to do so.
The weak race alliance seemed to be in a state of disunity. It was comprised of warriors from various weak races across different domains, functioning like a mercenary organization platform with no absolute commander.
The higher-ups of the weak race alliance were more like the creators of the platform, but they were not the controllers of the alliance and did not have decisive command.
It was just like how the black shadow faction behind the Science and Technology Research Institute had wiped out Breaking Dawn back then. It was extremely difficult to eliminate the enemies to be in a state of disunity.
If they encountered bloody suppression, the weak race alliance would collapse completely. However, the warriors would still be rooted in Star City. It was just that without a systematic organization, their efficiency would decrease greatly.
