"Master, I Have detected that Mothra had an egg in its body."
A blue light flashed in Eighth Day's eyes. It was estimated that it was scanning the corpse of Mothra.
"So the one that flew out before wasn't an egg?"
Jack was confused. On that day, he and Eighth Day had seen a glimmer flying out, and from the photo, it was also an egg.
Was there a fake egg in it?
"Master, Mothra has many eggs, but the chance of survival is extremely low, and only the eggs with the strongest vitality can successfully hatch into butterflies."
Eighth Day Explained.
"Then the one in its body now..."
Eighth Day understood and took out an oval worm egg from the corpse.
"I have detected that it had a very weak life force and could die at any time."
Jack didn't expect that Mothra had a descendant before it died.
