takes 'countless blows from thor'

How many times had he felt his fists smash into flesh and blood?
How many times had he watched the boy roll through the deep snow?
He heard a train’s wheels striking the track in the distance.
The next thing Thor knew, they had moved away from Egeskov Castle. Were they a few
dozen meters away or a few hundred meters? He turned around, but the castle had
vanished in the white scenery. Kamijou Touma’s repeated and futile attempts to move
away and the countless blows knocking him through the snow had added up to that simple
result.
