Although it's unexpected, Robert is still happy because he's achieved his goal smoothly.
Soon everyone registered their name, Age and Cultivation base to Robert. Buster, Valor and others joined too.
Of course, their treatment is different from others as they do not need resources to enter the foundation realm.
So Robert gave them a salary of six Grade two spiritual food per month.
This isn't a fixed salary but a temporary one. In future, he might increase or decrease the salary depending upon the situation.
But others are more than happy with the treatment because their cultivation can upgrade by one subgrade every two months by consuming six grade two spiritual dishes.
Axel and the other two have special treatment because of their special situation. Previously before leaving Aunt Rosy mentioned that there is a problem with their bloodline which resulted in slow cultivation speed.
