The zombie was burning up and what Kreiss said was right. The zombie didn't die yet, but it is indeed effective and they could deal damage to it now.
Sheloah and Kreiss just stood there while Veon and Shannara continued on shooting the zombie. The flame was about to extinguish and once it is already gone, Kreiss and Sheloah can now attack.
Kreiss looked at Sheloah. "Ready, princess," he asked and Sheloah nodded.
The both of them held their katanas tightly the moment the flame disappeared. The both of them ran and Sheloah impaled the body of the zombie while Kreiss focused on beheading it. Once the blade of Kreiss' katana went through the zombie's neck, he found it difficult to slice through.
Kreiss looked at the girl with him. "Sheloah, now!"
The moment Sheloah heard his signal, she removed her katana and also impaled the zombie's neck. In one direction, both of them sliced the zombie's head forcefully, making the zombie lose consciousness.
