Raven didn't move. No, it was better to say he didn't dare to move in fear if he does he will accidentally make the key's sharp tip sink into his throat more than it should be.
On the other hand, Kayn just stared coldly at Raven from above, his eyes staring daggers at him almost as if he wished to drill through his head with his gaze alone! Then, he slowly turned his face to the side and spit, painting the floor beside Raven with a mixture of blood and saliva.
"You know, although you look small and fragile, you have a very strong punch." Kayn pointed out, showing no signs at all that he wished to take the key away from Raven's throat. Instead, he even pressed it more against his neck, drawing blood through a small wound as a result!
'Fuck! He is not joking! He will really cut my throat open if I move!' every muscle in Raven's body stiffened and the playful thought in his head to punch Kayn's hand to the side with one fast and strong move immediately vanished.
Watching how Raven's face paled when he pressed the key against his throat more firmly, Kayn pondered for a few moments before he sighed softly through his nostrils and stood up.
"You lost, again, but that is okay. "
Raven immidieatly touched his throat when Kayn stood up, making sure there was no grave injury. Luckily there was none so he was able to let out a sigh of relief and raise his gaze, only to see Kayn's hand extended toward him, seemingly as a gesture to help him up.
'...' Raven didn't say anything and without accepting the 'help', which was very like another bait, he pushed himself up from the ground.
Seeing this, Kayn lowered his hand, but the small upward curve at the corner of his mouth told others he was satisfied with Raven's decision.
"Here. I think this belongs to you."
"Eh?" watching as something was flying toward him through the air, Raven was first puzzled before he quickly reacted and raised his hands, cathing the item with no difficulty at all.
"Didn't you say I should take it back by myself?" Raven furrowed his brows when he saw the thing he caught was the Backroom Key and not something else.
"I did, but then I realized even if you would be given all the time in the world, you would still fail to take it back from me," Kayn replied indifferently, stating facts.
Hanging the key back around his neck, Raven raised a brow and felt bewildered. Then what was the reason he was beaten up twice? It made no sense!
"I am pretty sure now you are wondering then why I had been going so far as to beat you up twice, but don't worry, there were in fact two reasons." Kayn explained and raised his hand, showing two fingers, "The first one was to make you understand that there will be always others stronger than you, and if you are not strong enough you can lose everything in a blink. And when I say 'everything', I literally mean everything kid."
A hint of sorrow and regret flashed through Kayn's eyes when he said those words which only lasted for a second before disappearing in a blink. This, of course, was something that Raven was able to spot, but instead of deciding to open up old wounds he asked;
"And what about the second reason?"
"It was just to simply see what you can and can't do. I even planned to harm your little sister a tiny bit as I heard you two were pretty close to each other, hoping that way you will show your real worth, but as she was not around I had no choice but to use that key instead. It seemed pretty important to you, like, damn, even as you were lying on the ground unconscious you were still clenching it as if your life depended on it!"
'...'
Raven's face darkened immediately upon hearing Kayn's words. Though, instead of starting a fight with Kayn like a stupid and cringe little kid throwing a tantrum he instead took a deep breath and quickly calmed himself down while secretly feeling a little shocked.
'This is weird. He held the key yet he didn't get to read what it does?' thought Raven a little confused but didn't his puzzlement to be shown on his face.
Seeing this, Kayn nodded once again, feeling even more satisfied with Raven, and walked before him.
"Anyways, now that I know what you are capable of doing, or at least here in real life, let's start with the real training," Kayn said then he grabbed and pulled Raven's hand toward him until it was fully stretched.
"First of all, your punch. I see that you learned how to fight back when they attack you, but I can also see that except for self-defense you are just a noob." Kayn said calmly and made Raven clench his fingers into a tight fist.
"While your punch was strong when you hit me in the face, it was just only enough to make my head move to the side a little and not to force me to fall on the ground or to urge me to retreat. What do you think, why is that?"
Raven watching how calmly Kayn was talking lowered his gaze and pondered, recalling his previous fight with the giant in front of him.
"Because... You are like a massive rock?"
Kayn raised a brow but quickly began to laugh and shake his head, "Haha! What? No, not at all! Though I will take that as a compliment."
Then, once he stopped laughing, Kayn let go of Raven's fist and put his hand on his shoulder, "The reason why you were not able to deliver me a devastating blow was because you only used your arm."
Saying those words, Kayn walked to the side where a boxing bag was located hanging from the ceiling and once he was in front of it he used only his right hand to punch it.
The result was rather pathetic indeed.
"As you can see, I only used my arm when I punched and the result was the bag only moving backward a little. However, if I use my shoulder together with my whole body..."
BAM!
The punching bag immediately was blasted backward, only the chains attached to its top stopping it from flying away into the distance!
"See? If you go and use your body as a whole the amount of strength and force you can put behind your attacks, especially behind your punches will grow drastically!"
"Using my whole body?" Raven mumbled as he pondered for a few seconds before taking up a stance, lowering his posture, and throwing out a punch, this time using his whole arm shoulder, torso, and even waist!
Whoosh!
A quiet and weak breeze was generated once Raven finished his punch, earning a soft nod from Kayn!
"You really do learn fast, huh?" Kayn expressed with a low hum and pointed at the punching bag, "Now use that knowledge on this. Punch it a thousand times."
'...Huh?' Raven's eyes widened thinking he just misheard Kayn's words he asked, "I am sorry, but did you just say... a thousand times?"
"You find that too little? Sure, let's make that two thousand."
"What? I didn't even say-"
"You know what, let's make that three thousand. Yeah, the more the merrier." Kayn asserted before adding, "Oh, and as you can see, I sent Thomas away and even asked him to close the doors. So until you won't finish your three thousand punches you can only dream about seeing the outside world."
'...'
Raven stood motionlessly in one place, his teeth firmly clenched together.
"So? Will you start punching already or do you want me to add another thousand to that three thousand?" Kayn asked with a raised brow, his arms crossed before his broad chest.
