After that, Flandre never saw Belatu again.
Lin Xun had already known about the rest of the narrative. He could largely fill in the remaining gaps through reasoning.
In the early stages of the war, Firefly had an overwhelming advantage. The Wet Nurse breaking down Firefly's genes was a desperate measure, and the only chance for a reversal.");
Probably, Firefly presumed that Wet Nurse definitely couldn't decode the gene. As for those like Flandre and Belatu who self-identified as rebels, they were also rejected, since the outcome of the war was already decided, and there was no need for unnecessary complications.
It was not until Wet Nurse had tested all of her offspring and failed without exception that she had to make a last-ditch effort to burn her divine body and break down the Firefly gene.
No one expected that Wet Nurse's desperate gamble would succeed, and from that point, the tide of the war instantly turned.
