With Vincent's help, Irene was soon recognized as the king of the underground world. She picked out some of the stronger and more prestigious creatures and gave them some survival skills.
For example, she told them about where they could get the cheapest food. She also told them about the weapons and blueprints produced in the underground world and where they could be sold for a good price.
The channels that Irene had provided for them were all controlled by high-level races, so they were relatively safe. There would basically be no situations where they would be killed after the transaction.
With the availability of these few basic channels, the underground world could select a few representatives to go and exchange resources with the outside world.
However, even so, the amount of food that they could buy was far less than the amount that Irene had brought. Hence, Vincent's cleansing of the underground world earlier was especially important.
