"No, it doesn't"

Ezra replied as he slowly began to stand up, while the smoke that was spewing from his body intensified

"What the hell? ..."

Shu questioned while a nervous smile grew on his face as Ezra's body ascended from the ground

"I hit you with the best I could give, how are you still standing?"

Shu asked as he looked up at Ezra, who relieved his leg of his grip

"The best you had wasn't enough, that's all"

Ezra replied as he cracked his neck before taking in a deep breath, proceeding to swiftly punch Shu's face, bringing his arm down, slamming Shu against the ground, creating a crater the same size as the one Shu created, causing the same effect as well, cracking the walls in the room even more while blood began to drip from Shu's face

Shu's pupils were nowhere to be seen, as his mouth stood wide open and his arms stretch out while he laid on the cold ground that was the empty room, it seemed as though Shu was unconscious

"There, I calculated the amount of strength you used and dished it back at you, how does it feel?"

Ezra questioned as he rubbed his neck, moving his head from left to right as if trying to relieve himself of the small amount of pain Shu dealt on him, before proceeding to close his eyes as he would then turn his body around, beginning to walk, but right when he did, he could not do anything else but stop, as he felt a small amount of pressure behind him

"The way you celebrated when you knocked me to the ground was as if you expected for that amount of strength to be enough to lay me down, so the fact that I hit you with that same amount should have been enough to have you snoring by now, thus I ask you, how are you standing up?"

Ezra questioned in disbelief as he turned around, seeing a weakened Shu slowly walking over to him.

Despite his sorry state the amount of energy he was letting out was abnormal for his age, it almost resembled that of a forest fire

"I don't know, maybe it's just because I'm too excited right now"

Shu replied with honesty as a grin grew on his face, slowly proceeding to move his thumb to his nose, pressing against it before blowing out blood

"Stay down. I mean just look at you, you have bruises everywhere, I get that you want to show off by acting tough, but that punch did knock you out for a few seconds"

Said Ezra, trying to reason with the boy, showing a little bit of concern for him. But all that reasoning and pleading was for not, as Shu would then rush at Ezra, with the chuckle of a devil and the speed of a demon

"Huff, have it your way then"

Ezra whispered with a small sigh of disappointment, rushing at Shu right after, swinging his left fist straight at Shu's face, but right before the fist could even rich the trajectory of his arm would change, completely avoiding Shu's face as if a ghost had interfered

"What the hell was that?..."

Was all Ezra could even stutter before receiving a punch to the stomach, as strong as the kick Shu was able to pull off before, causing him to slide through the ground as if a strong wind pushed him

"I'm getting the hang of it.."

Said Shu as he stood straight, staring at Ezra from afar as the grin on his face grew larger

"Get the hang of it?"

Ezra questioned as he stared down at his own stomach, resting his right hand over it, blinking in confusion

"Well, grandpa always told me I had too much Sanctuary Energy for a being of my age, back then he would constantly teach me how to harden and strength my body with Sanctuary Energy, but because I only followed those specific teachings I couldn't grow.."

Shu replied while jumping from left to right, moving his shoulders up and down as Ezra simply stared at him

"What are you talking about?"

Ezra questioned while slowly beginning to walk over to Shu, causing the hyper child to smile

"What I'm trying to say is, I just put everything into a certain limb and switch it all to another limb when I need it"

The boy explained while appearing above Ezra, sending a kick down to his right shoulder, landing it perfectly, making the man kneel down from the weight of the kick

"Cool, isn't it?"

Shu whispered with a smirk on his face before pushing himself off of the man's shoulders using his legs, landing on the ground with carefulness

"That shouldn't be possible"

That was all Ezra replied with, while slowly standing up, wiping off his shoulders as if dust had landed on them

"Huh? What are you talking about?"

"You said you put everything into every singular attack, right?"

Ezra questioned as Shu simply nodded

"Does that include reaction and movement?"

"Yes"

"Then you should be in the ground begging for more Sanctuary Energy right now, it goes against the laws of physics, if you put everything you have into something then that would mean you don't have any more of it, energy always comes from somewhere, you don't just randomly obtain it, plants grow with sunlight, water, and good soil, while we humans grow with food, sleep, and care. So the fact that you can just constantly use your 'everything' in every move makes absolutely no sense"

Ezra explained making the boy nod while a hint of confusion strolled around Shu's eyes

"I have absolutely no idea what you were talking about, but in short, you're saying I'm special, right?"

Shu questioned with a smile expecting Ezra to answer and explain just like he did a second ago, but before he could think of yet another question, his consciousness began to fade, feeling a fist sinking down in his stomach, as all he saw while falling to the ground was Ezra's calm expression

"No, it just makes you a bit more interesting"
