With the destruction of the main golem, our first problem was now gone. The people who run the factory are either captured or managed to escape. I didn't care whether some had escaped as it's natural we can't capture everyone. As for the siblings who are apparently the president and the vice president who governs and manages the factory, well, they are gone and reduced to atoms after the laser beam that accidentally got fired at them which resulted in their evaporation. Nothing was left on them, even their clothes and bones were not spared and everything disappeared.
As for the mass-produced golems, we have to manually destroy them, and since they are much easier to destroy compared to the big golem. Of course, Gamma was a big help in cleaning up the golems. With its abilities, it easily destroyed most if not all of the remaining golems.
