After talking for a while with the people in that bar, Eden had already completed his mission and was just waiting for these men to prepare to travel with him.
There were not 50 people there in that establishment. Still, all those who were there either needed an opportunity like Eden brought or knew someone who needed it.
As a result, he no longer had to worry about attracting more people to the Dry City. Only those who were at the bar would be enough to spread this information to as many people as he wanted.
And that happened with the other four soldiers of the Black Plain Army who was fulfilling this mission, passed by Minos.
It was not difficult to attract the interest of humble people, who needed to run after every spiritual crystal they could get. Life for people with White talent was difficult anywhere, so it wouldn't be bad for these people to get some extra crystals.
