`` you should be a good one , '' steel said and moved up the gun with the same quickness , a sound of gun stopped the time for a moment and then steel smiled a little bit and then fell down , his one hand was in a pocket and the other holding his gun , at last the story of twenty years ended in just twenty seconds goku killed his father , we were in a dilemma as to what we should do , burst with happiness or give some help to goku in that sad time , mr yaseen moved towards him .
