The experiment going on was to determine a few things. The main point was whether the liquefied energy, having undergone a change in quality compared to freshly extracted energy, could be absorbed. And as the professor had said, the durability of the body seemed to be the crux of the matter.
Another point was to confirm what Lucas had inferred, namely his inability to keep evolving, at least at the moment. After all, before trying the liquefied energy, Estrella and him had been through the test with the energy of lower quality. And at that time, while Estrella had felt a positive effect that had only been too insignificant to be relevant to her state and push her higher, Lucas, on the other hand had felt nothing, with the only hope for him to not fall into a difficult path being the low quality of the energy being determined to be the cause.
But it seemed that his situation was indeed different, from the result of the first phase of the experiment.
