"The area I was in had no proper path so it was like walking an obstacle course for days." Senku sighed. "We were meant to repair broken pipes, and some of the robots came over to hit you when they were broken, so we were meant to be fixing them too. But the world was under construction so it didn't have anything of interest to gather, and somehow I ended up in combat. Could've been better."
