Chapter 237: Chapter 237: Interesting NPC

....

The Wind Mage kept rushing down the mountain, however even as she reached the place where she felt the traces of the shadow, she hadn't seen anyone.

Along the way, there was not a single person that she had seen. She wasn't sure if the person she was supposed to kill had already run away?

She felt slightly glad. Even if the person could help her, could she really ask for his help? She couldn't even open her lips to ask a question without the permission of her son, all because of that otherworldly slave seal.

Even though she had studied magic all her life, she had never heard about the existence of a seal like that. It was like some monstrous ability that had appeared out of thin air around the same time that her son had changed.

Her eyes were still filled with many questions, but in this hell, she couldn't do anything but watch her son ruin the lives of other people.

She prepared to continue searching as there was no point in returning like this. The seal didn't let her return without killing the person.

She checked the traces that were left behind to check which direction those people had run in. However, strangely enough, the traces led towards the peak of the mountain.

She didn't understand how it was possible. If that was the case, she would have come across them. Did they use some ability to get past her? She wondered.

As she was lost in thoughts, she suddenly felt killing intent directed towards her. She jumped around, barely dodging the attack that had come straight for her neck.

She didn't even see the attack. If it wasn't for her winds, she was sure she would have been hit.

She turned around, looking at the source of the attack but she couldn't see anyone. The person was invisible, to the point that he couldn't even see their footsteps on the snow beneath.

"Are you the person who killed him?" she still asked, looking in a particular direction.

Even though she couldn't see that person, she was the mage of wind. In this mountain, even if one was a spirit, their bodies weren't immune from being detected by the winds.

"Do you know what you did?" The young Transmigrator frowned, his eyes brimming with killing intent.

This person had made him lose his key. He was so angry that he wanted to kill this young man right away, but he controlled his anger.

"Oh? Was he a friend? My apologies. I thought you were being kept hostage by him," Eren shrugged as he pulled his sword out, letting the lifeless body of the Necromancer fall on the ground.

As his slave was killed, the master of the slave seal also felt pain. However, the Transmigrator didn't reveal pain on his face. He only bit his lower lip.

"You are quite a foolish NPC, aren't you?" he asked. He was free, and not tied either. How could one think that he was being kept hostage.

He raised his right hand, using a skill that was similar to the identification of Eren. A screen was supposed to open in front of him with the stats of the person he was facing.

This ability was also what allowed him to survive through many life threatening situations. Unless it was someone on the level of an Overlord, the skill never failed him.

The only other exception was if the other person was too weak for the status screen to work.

"Hmm?" His expressions suddenly darkened as the screen opened in front of him.

Unlike the normal status screens that showed in blue color, this one was pure black. In the middle of the black screen, there were only three words that were in blood red color.

"Failed to detect? What an interesting NPC," the young man lazily said. "Since you took a slave from me, I will make you fill his place."

"Young man, you should thank your stars that you would get to serve the next ruler of this world!"

Eren didn't pay attention to the words of the man. He simply looked at Feng Yu, who was lying on the ground, her eyes closed.

He was slightly glad that she wasn't awake, because he was about to do something that he didn't want her to see.
