Dokot's ability was indeed quite special, as he could extract the negative conditions inside one person's body and transfer them to another.
At that moment, Berg's injuries were transferred to Guding. As Guding endured the injuries, he merely furrowed his brow and did not even utter a sound of pain.
Berg's remaining injuries were not severe, just some cracked bones, visceral shocks, and traces left by surgeries on his body. Since there were no destructive sources inside Guding's body, these injuries, once transferred into him, were fully healed within a few minutes due to high-speed regeneration.
After Dokot completed this task, Guding escorted Marcken and Dokot out of the cabin, but then pulled Dokot aside.
