Not long after, Roy caught up to Julia.
Seeing Roy coming so quickly, Julia was extremely shocked. She naturally knew how difficult Ulthane was to deal with, but it was precisely because of this that she was shocked.
However, she did not ask Roy about the specific process. It was not easy for demons to survive in society, so almost all demons, including her, would leave a trump card. She could not casually inquire, even though they had become partners.
The closer they got to the central area, the more low-level demons they encountered. When these low-level demons saw Roy and Julia appear, they all chose to follow them without exception, so the demon entourage that Ulthane had killed was replenished.
In this underground bunker, the living areas of the surviving humans and the armory were separate, so when the humans saw Roy and Julia bringing a large group of demons to the armory, the survivors both rejoiced and felt uneasy.
