It says the story is about the Worm saving the planet from destruction but when you finish it the planet blows up and it says congratulations? I dont get it, someone care to explain if I am missing the point?
Mother Earth is on her last breaths, and sensing and maybe even accepting the end approaching, triggers the super mega worm as her final act to get her revenge. While there is a slim change the worm will eradicate humanity and save the Earth, it is not clear whether it's too late. Ultimately it doesn't matter, as the worm becomes so powerful that the Earth itself is destroyed.
