A few minutes before midnight, Ainsley and the others, including the old commander, started to take a break in turns.
The demons were indeed crazier at night, but with the natural field that everyone created, which could already function normally like a real thing without everyone manipulating it every single second, there was really no need to work hard to kill demons.
These warriors all saved up their strength and just made sure that the barriers could last long. They all tacitly left the job of killing demons to Ainsley and the vanguards.
Even when Ainsley was resting, the bloodline suppression would still help her kill more demons using the hands of those demons.
The vanguards and the original rooftop team members could not really rest well because they didn't want to miss another strong demon that might be a threat to them.
