Arriving at this point, there is still nothing really surprising, not even the galaxy-level beings observing the battle from the outside felt there was anything peculiar.
Although the giant egg was indeed somewhat unexpected for them, what followed was not so surprising. This giant egg is merely an interlude. While everything is under their control, there's nothing unexpected. Even if the giant egg has more defensive capabilities, they don't believe they will fail; at most, they'd step in personally, and the giant egg would be directly obliterated.
They just want to use this battle with the giant egg to see if the Country of Taia has developed technology that makes them covetous, and also to observe whether their subordinates have the ability to deal with these unexpected occurrences.
This is all very useful information.
Bang!
