"Xia Zhou..." Helenberg contemplated,
"Are you suggesting that we should set aside some time to research the inner shell of the Flying Shuttle Sea Hare, is that correct?
"The inner shell might have some unique features or spell enhancements that we're unaware of, which could have caused damage to the sturdy submarine chamber.
"But the duration of this destructive power appears to be quite brief, in my memory, from the launching of the inner shell by the Flying Shuttle Sea Hare to the crushing of the shell by water pressure, it only took about one to two seconds..."
As Xia Zhou expected, the natives of this world, when confronted with unknown events, always first link them with mutations, spells and the like.
This approach is not wrong, and it converges with scientific research methods, both will eventually discover the existence of superspace bubbles.
Xia Zhou borrowed the answer from his experience of visiting the military museum in his previous life.
