To defeat the fire Golems and their troublesome area of effect ability that was born and they were together, there was only one way to deal with it… Get as close as possible and attack with ice magic. Thanks to that, Billy's attacks weren't losing power and even the twins bolts were slowing down the enemies approach. However, they felt like they were in hell due to that heat. To make things even more complicated, the bodies of the Golems still emitted a lot of head after they died… to counter that, Billy used Niflheim, but the spell barely could give them ten seconds of relief. So, he had to keep casting the spell over and over again, while he also was firing ice spheres toward the fire Golems heads.
"Billy, i think…" Samuel said while looking around and noticed that the enemies had completely surrounded them.
"Shut up, idiot," Samara said. "You will mess with his pace and focus."
Samuel finally noticed that despite being so close to the fire Golems, not fire magic was approaching them. The reason for that was the fact that Billy was killing all fire Golems, but he was focusing on those that were about to use their magic or were about to charge.
Billy was basically spinning and firing magic like a turret. His precision was phenomenal since he leveled up Hawkeye… Still, Billy was using all the mana he was getting because he couldn't focus on anything else on those moments.

Despite the difficult situation, Billy's powers and skills were improving by leaps and bounds. Still, pretty often, unexpected things happen… The Golems realized that they would never reach Billy that way. So some of them just jumped. While they didn't reach much high due to their weight, they still managed to escape Billy and the twins' usual area of attack. They didn't escape from his senses, though. Without even looking at them, Billy created and fired some ice spears that pierced them from bottom to top easily, killing them instantly.
"When you see the Golems doing something out of the norm, you should stop them," Billy said.
"Yes, sir," Samuel and Samara said in unison.
Those two had said before coming that they wanted help, but in the end, they realized that Billy didn't need it. Their older brother could do a lot more by himself than by working with others. Samuel didn't hide that, but even Samara was getting carried away with her skills recently since the kids of their same age couldn't spar with them properly. Still, after seeing how Billy could fight and still was so serious with training despite being busy as well with his family and kids, they realized that they still had a long way ahead of themselves…
Eventually, even Billy got tired of spinning in order to make sure that the enemies wouldn't have the chance to attack. So, he changed his tactics a little bit… He condensed the air around his group and then made it expand while it was spinning. Eventually, a massive ring of ice reached the fire Golems and began to cut their heads and cored. Since they had the same height, Billy didn't even have to aim. Still, that only worked for a while since the heat of the area decreased the durability of the ice ring and eventually, it became useless. Attacks of long-range were no good, but Billy decided to use that now and then to take a break from the attack and spinning.
Billy and the twins kept fighting like that until sunset. Although they didn't use their bodies much, they still got pretty exhausted. It was no surprise due to the heat and the fact that that pretty much-eliminated one-third of the fire Golems surrounding the city.
"How many times do we have to do that?" Samuel asked after they moved away to take a break once it got dark.
"Considering how many monsters approach this area every day, I guess it will take three more days to finish all things here," Billy replied. "Still, just helping this place for two more days should be enough. The rest we can leave in the hands of the people inside the walls."
Samara thought that it was a pretty sloppy thing to do, to not finish the job completely. Still, she knew that there were other places that needed their help, so it couldn't be helped. Despite all the hardships they were facing, things weren't so bad. Finding food around was pretty easy and Billy even made a pond for them to clean themselves and relax since the water was pretty warm. While they did that in turns, Billy used Mind Control to keep sending fire Golems to fight the others that were coming. That was absolutely necessary, otherwise more than half of the monsters that they had killed would come from the south. He had to slow them down as much as possible in order for them to have a plausible task instead of an impossible one in front of him.
Fortunately, things weren't so bad inside the walls. With the help of Billy's friend's students, the people inside had been able to take down the fire Golems attacking the walls pretty often. Maybe they recovered their fighting spirit after seeing just three people eliminating so many of those creatures.
"Rest for the night, we will face the same pace tomorrow morning and I am planning to keep at it until sunset in order to eliminate more than we did today," Billy said.
In the end, the twins didn't argue about that. They were exhausted, after all. Once again, they went to sleep while trusting their older brother to watch over things and while he did that. Billy also smashed the heads of some Golems with Earth Cannons.
