Theory:
Then it is possible that the protagonist has built a pedal car like the ones you saw in old souls where the power of the engine is replaced by people on bicycles.
He may have stolen / borrowed his master's set of spheres.
the protagonist is getting himself into trouble because he is rebelling against the one who is the object of his wife's revenge, if he proves the master's innocence is over, they put him on the black list of people to be eliminated!
