The Tyrant zombie's sharp claws pierced directly through the mutated giant beast's skull, extracting an energy-filled crystal core.
Just as Lu Chuan had judged, this mutated giant bull had already reached the second tier, and the crystal core in its brain was almost turning orange-yellow.
'Tyrant No. 1' delivered the crystal core to Lu Chuan's side. Looking at the two second-tier crystal cores in his hand, Lu Chuan nodded in satisfaction.
"The second-tier crystal core from that mutated Golden Python earlier, combined with this mutated bull's crystal core, should contain enough energy to allow 'Er Pang' to successfully break through to a third-tier zombie."
Now that the threats within the farm had basically been resolved, Lu Chuan began to dispatch a large number of Corpse Puppets into the internal areas of the farm.
