Grey tracked the aura of the young man, and before long he soon appeared in front of a room. The door was shut tight and the screams of the young lady could be heard from inside. "As long as you're mine, I promise, Teacher will not harm you. Of course, the same can't be said for your father." The young man's voice came from inside the room. "My father knows we came here, if I don't report back within a day, he would know something is wrong and come looking." The young lady's words were a clear warning, if anything happens to me, my father will come and kill you all. "Heh! You'll be dead before then, so what if he comes, it's not like you will be able to see him." The young man sneered. The young lady's threat only seemed to anger him. "The same can be said for you." Another voice was heard in the room. The young man who was pressing the young lady on the bed hurriedly stood up and looked around, "Who's there?" He didn't hear anyone open the door to the room, and neither did he sense anyone entering, so he was alert. "You don't have to panic, just stand still, let me kill you." Grey's voice was like from the underworld. He appeared behind the young man, and as soon as he turned, Grey's eyes glowed with a blue light. The young man froze the moment he saw Grey's eyes, standing still. The young lady panicked when she saw this and hurriedly dragged the bed sheet to cover herself, looking at the masked man, alarmed. "You don't have to worry, he's dead. Wait for my signal before you try to leave." Grey's figure vanished the next second after he finished talking. The young lady looked at the young man, shocked. She couldn't believe that without even making a move, Grey managed to kill him. She was already in the Overlord Plane, so it was easy for her to sense if the young man was still alive or not. 'Isn't he the one I saw in the restaurant?' She was a little confused, Grey's clothing resembled the one an Origin Plane Elementalist she saw at the restaurant was wearing. She didn't get a good view of him, but she recalled that she saw someone with exactly the same clothing. The memory of an Overlord Plane Elementalist was very good. While she was still thinking if Grey and the person she saw at the restaurant were the same people, Grey had already sneaked back underground, he still had to save the young lady's companions, as well as the few people who were still alive. Two people were there, guarding the place. They were both in the Sage Plane, but only in the Early stages. They were not worth mentioning in front of Grey, if he were to truly attack, they might not be able to survive a single attack, much less buy time to be rescued. "Void, I'll deal with these guys, make sure the old man doesn't escape." Grey whispered to Void. Void nodded his head and vanished. Grey knew that the moment he took anyone from here, the old man would know, so he didn't plan to hide any longer. He moved closer to one of the Sage Plane Elementalists and attacked. With one attack, the Sage Plane Elementalist fell to the ground with a thud. He didn't even know how he died, his eyes were still wide open. The other Sage Plane Elementalist turned around to see what was going on, but Grey appeared in front of him and unleashed a fist that had three elements covering it. The moment the attack hit the man, it was followed by an explosion. The man managed to survive the original attack, but he was barely alive, he couldn't move and all his ribs were broken, most of his internal organs had been punctured by the broken ribs. Grey walked over to him and he did a closing motion with his fist, a large arm made of that earth element sprouted out from the ground and squeezed the man till he died. Grey then turned to the people in the place, looking at the barely over twenty people who were still alive, he couldn't help but shake his head before taking them out of the place. The young lady was already dressed, so the moment Grey returned, he took all of them out of the compound before disappearing once again. He wanted to make sure Void wasn't interrupted as he held back the old man. When he returned, the old man was squaring off against Void. "You filthy beast, did you kill them?" The old man asked with an angered expression. "I did, so what, what can you do about it? Lousy old man, come, let master cat teach you some manners." Void laughed haughtily as he attacked. The two Sage Plane Elementalists at the side of the old man were on the ground, dead. Void came here, and with a sneak attack, he was able to kill both men before the old man could even react. He killed them almost at the same time Grey took those people out, so the old man couldn't be bothered with them. 'You didn't leave any for me?' Grey asked, annoyed. Void threw a glance his way before saying, 'They're in the courtyard outside, they will come soon, enjoy.' Grey nodded before disappearing. He could sense the people rushing over, and among them, the three at the Peak were with them. Other than the three who were at the Peak, three more of them were in the Late stages of the Sage Plane, then the other four were in the Mid stages. Against any other Peak Sage Plane Elementalist, they were almost guaranteed to win, but against Grey, their numerical advantage was basically useless. "Stop, I'm your opponent." Grey appeared in front of them and stretched his hand in front of him, stopping them in their tracks. "He's only in the Ninth stage, take care of him." One of the trio at the Peak pointed at another one of them. The man nodded and walked towards Grey, the others continued their journey.
