He thought it would be another fruitless search, but then something caught his eye. In the room, there was a white metal box, and inside it were numerous crystal nuclei, including some fifth-tier and fourth-tier ones. The total count was in the hundreds! These had been collected by the Zombie Hunter Organization over the course of three months.

Shaun's face lit up with joy, as he hadn't expected such a windfall. It explained why elite zombies and mutants were so scarce in the city center; they had already been cleared out by the organization. This revelation saved Shaun a lot of trouble.

After thoroughly searching the entire laboratory and finding nothing else, Shaun ordered all the zombie lords to return, preparing to infect the entire organization. There were quite a few awakened individuals among them, and crystal nuclei were still valuable for providing evolution points to his Orange Cat.
