After Ainsworth accepted the Road To Zombie King (S) side mission, he also received the choice reward, which upgraded his Evasion (B) skill to Phantom Evasion (SS).
Furthermore, he also commanded Kyle to quicken his pace. Kyle was already his slave because he was part of his Hive Mind, so he didn't mind commanding him to do unpaid overtime work.
Even his fanatical believers were doing their best and using almost all their time in the day to spread the religion of the Church of Evolution. That didn't give Kyle, a zombie with limitless stamina, an excuse to slack off.
After deciding on the side mission, Ainsworth shifted his attention back to the survivor group who had taken a rest under his command.
When he looked up at the sky and noticed that it was getting dark, Ainsworth ordered, "There's a hotel nearby, so we'll make use of it as our temporary base until daytime."
