Ian looked at the branches before looking at Maroon who bowed to him right after the first glance, "I smell a Demon from the tree," commented Ian his red gaze moved to the handkerchief when he saw the black blood.
Maroon outstretched the hand which was holding the kerchief, "I believe a Demon must have infiltrate inside."
Ian could tell the blood didn't come from other two Demons in the castle after him which was Maroon and Beelzebub. The blood was thick, and he frowned at it. "Did you sensed anyone coming inside the castle?"
Maroon shook his head before bowing, "My apologies, milord."
"It's not your mistake," dismissed Ian, "If they are able to come inside without being noticed by you or die from the barrier I created around the castle, there is only one possibility. It's a higher level Demon." His frown knit tighter. There shouldn't be Demon higher than him unless the head of Hell leave their position to come to his castle which was impossible.
