After Oliver's team questioned everyone whether they had procured ability crystals or not, the final result was much better than expected.
"47 Survivors have yet to procure their ability crystal. Should we lead them to the second floor? There are more than enough imprisoned zombies separated in the patient wards."
Oliver's idea was good, and with the Kobolds' weapons killing a single unleveled zombie would be easy for the new survivors.
There was nothing for Dilan to add, which was why he gave Oliver the authority to go ahead with his plan.
Even if he had just crowned himself the leader of their group, Dilan knew that he had yet to gain the trust of everyone, let alone their unwavering loyalty.
Furthermore, it was not as if he could take care of everything all by himself.
He was only one person and not a machine that worked 24/7.
As such, sharing his burden with the others was the easiest to show that he trusted them.
