Fortunately with Rein's identity as a mithril rank powerhouse, they did not face any problems regarding the capture and the killing of the criminals. The magic gadgets were also recovered safely and were not very much damaged which was a good thing for everyone and were immediately put into use again.
But the other gadgets were all a bit damaged because of the high load that they needed to endure and the city needed to get some magic technicians to come and repair them. But still for the time being the city was able to avoid the danger of getting destroyed with a landslide.
Obviously Rein and Anna become a hero for the city. Especially Anna as her exploits were seen by many. They were also offered rewards by the city lord governing the city but both of them rejected it as the reward he would be able to afford would be nothing of value to Rein or Anna.
