Kai continued screaming no matter the time. Despite preparing his heart to receive pain, the pain was beyond his imagination.
If not because he had good mental fortitude, he would have passed out.
Arba and Aston could only watch from afar, hoping that Kai could succeed. They obviously didn't know the degree of pain, but they knew that Kai wouldn't scream just being stabbed by his enemy.
That was why Aston quickly prepared everything Kai would need later while Arba watched over him.
After a whole day, Kai was still screaming, but he somehow glanced at Arba, maintaining eye contact with her.
At that time, Arba realized what he needed and raised her hand, lifting the food next to her. She carried it carefully, so it didn't touch Kai or the Magic Circle.
As soon as it was near Kai, Arba moved it a bit closer to Kai's face, so he could take a bite. Kai didn't hesitate and took a huge bite since he was quite hungry after enduring all this pain.
