Capítulo 753: 750, Rules of Singer Civilization - Relative Fairness_1

The rules Donna was referring to are the rigid ones set by the Singer Civilization, which even the Holy Silver Federation must adhere to.

The reason why the Singer Civilization encourages wars among the lowest-level civilizations like Blue Star, aside from opportunely plundering spiritual energy (70% of Blue Star's spiritual energy has been taken by the Singer Civilization), also implies an intention to "determine a more potentially advanced civilization through 'raising poisonous creatures'".

If Skru Star wins this battle, then they are the " more potentially advanced civilization". If they are defeated, the Blue Star would take their place as the "more potentially advanced civilization".

Assuming Skuru Star wins, there will be a rapid development window after they consume Blue Star.
