Fycro was at a loss for words. A level 17 godly item was indeed not something his body would have been able to take. But then again, it was not necessarily a requirement to fuse the powers with his Source if he were to absorb it. The way the Winged Skull put it made it clear that they were not giving Fycro a chance to rebel.
If that godly item were to fuse with his Source, that would have been the highest level he would have been able to achieve in his life—level 17.
That meant that there was no way Fycro could ever reach the pinnacle, with the highest being only at 17.
Saleen was at level 17 currently. So long as he managed to stabilize his level, he would be able to suppress Fycro securely using the power of lightning.
