Dragons start by digging corners of Kassel
Raise the chainsaw madman Lu Mingfei in the dream dungeon, let the senior sister who came to welcome Lu Mingfei's enrollment become a senior brother, create a world where the end comes, and wake up the arrogant half-breed from the false peace...... Traveling to the world of the dragon clan, facing the impending apocalypse, Bu Shun decided to start by changing Lu Mingfei's repertoire and transform this world little by little.
Wandering between this world and the other, with the power of the apocalypse, he chokes the throat of fate with his own hands. And then at the moment when the end of the apocalypse came, he brought the ship girl he summoned, the machine girl, and the lovely students to blow up those unknown dragons and gods!
———— characters that the protagonist can summon are all from the three games of "Blue Route", "Battle Double Pamish" and "Blue Files", but it does not affect the reading of readers who have not played it.
