The most basic hero's story has at least these few components:
Act One: The hero's birth (awakening as a hero).
Act Two: The hero's suffering (suffering a major setback and hitting rock bottom).
Act Three: The hero's baptism (obtaining the secret to victory, a weapon, like the Hero's Sword).
Act Four: The hero's triumph (using the secret to defeat the Demon King villain and achieve final victory).
Shen Feng had already gone through the first two acts. Coming to this world and discovering the cause of the Gray Tide apocalypse counted as his awakening as a hero.
And encountering the Mike Robot and the High-Level Construction Machine counted as the hero's suffering.
Of course, it hadn't really affected him much, but it could just about be classified that way in terms of plot.
So now, by following the clues to the Gray Tide Graveyard and finding the descendant of Arthur Seldon, he had found the ultimate weapon to defeat his enemy—his Hero's Sword.
