When Carrie went past the ivy wall that separated the camp, she saw that a great fog was blocking her sight. It was the visual effect of Abel's seclusion circle. She knew that, and she knew that it would be rude if she was to intrude Abel's private space. If the seclusion circle was open, Abel was probably in the midst of his training session.
However, an order was still an order. After placing her hand on the seclusion circle, Carrie released a small amount of mana to it. If Abel was inside the circle, he would know that someone was calling for him.
Soon, the fog around the seclusion circle began to disappear. A tent started to appear. Abel was walking out in a robe. He was holding an alchemy bottle in his hand.
"What is it, Carrie?" Abel asked with a surprised look on his face. He was obviously in the middle of something.
