Oripathy had originally been incurable with Terra's native technology. Rhodes Island could only ease the patients' suffering and alleviate their symptoms. However, Shen Fei used methods from another world to cure Oripathy, greatly slowing the spread of Originium.
Coupled with Shen Fei's origins in another world, this gave this world a final way out. Kal'tsit therefore made up her mind earlier than she had in the original work. And with Theresa still alive, Shen Fei learned quite a few things about the Previous Civilization from them. Originium had been created by the Previous Civilization.
The reason Shen Fei spoke of blowing up Rhodes Island was because it contained remnants of the Previous Civilization. Rhodes Island's highest authority was not in Kal'tsit or Amiya's hands. If nothing went wrong, it did not matter, but if something did happen, it would be extremely dangerous. Thus, Kal'tsit began preparing for the worst. She not only purchased mobile landmasses to serve as Rhodes Island's future base, but also had Shen Fei procure quite a bit of equipment that did not use Originium as an energy source.
Logically speaking, in this situation, it would be best to abandon Originium as an energy source. Unfortunately, they had relied on Originium energy for far too long and had grown accustomed to it. When Oripathy had been incurable, no one had paid attention to this issue, much less now.
Not to mention others—even Kal'tsit, Theresa, and those who knew about Originium's problems had no way to give up Originium energy. More importantly, there was simply no alternative energy source available in the short term. Mobile landmasses could not be powered by ordinary energy. Of course, Shen Fei could provide one, but that would only treat the symptoms, not the root cause.
Moreover, given Rhodes Island's strength, rashly producing
