Kael sat on the thin mattress in his small, rundown room, staring at the faint blue glow of the Echo System window. His body felt like it had been run over by a truck. The cuts from the subway nest and the shadow beast fight still burned under the rough bandages he had tied himself. Some of them had started bleeding again. Every small move sent sharp pain shooting through his side and arms. Blood had dried on his torn shirt, but fresh spots were soaking through.
The Echo window pulsed quietly, like a steady heartbeat inside his chest.

Instinct Echo (Basic)
Determination Echo (Fragment)
It wasn't some magic gift from nowhere. It felt like that faint spark he had first felt back in the rainy alley — the one that had made the old pipe feel different, the one that had helped him in the tunnel when everything was falling apart. The Echo was just that spark finally waking up and answering him. But right now it wasn't enough. Not even close.
"I can't keep fighting with nothing," Kael muttered to himself. "The inner energy… the spark… it's there, but I need a real weapon. Something that won't break like the pipe."
The next morning came too fast. His whole body screamed when he tried to stand up. Bruises and cuts protested with every step. Pain flared hot in his side. But Kael forced himself out anyway. He headed to the old warehouse on the east side that Rylan had mentioned. It was nothing special — just a broken-down building with cracked concrete floors, rusted metal beams, and a few beat-up training dummies. No fancy guild stuff. Just a place where low-level hunters sometimes came to practice.
When he got there, a couple of older hunters gave him quick looks and shook their heads. They saw a skinny sixteen-year-old kid covered in fresh bandages and probably thought he was crazy.
Kael didn't care. He started right away. Dodging imaginary attacks. Throwing punches. Swinging his arms until they burned. The Instinct Echo helped a little. His body reacted faster when he pictured a monster lunging at him. He could feel the old spark — that inner energy — moving under his skin, mixing with the new Echo. It made his movements a tiny bit sharper than before. But it still hurt like hell.
Hours went by. Sweat poured down his face and mixed with blood seeping through the bandages. His breathing got heavier and heavier. His legs started shaking. The inner energy felt like it was flowing better when he stayed calm, but the moment he pushed too hard it drained fast, just like in the tunnel.
One of the older hunters finally spoke up. A big man with a scarred face and a heavy iron rod in his hands.
"Kid, you're going to kill yourself like this. That's not training. You're just suffering for nothing."
Kael wiped the sweat from his eyes, chest heaving. "I have to get stronger. I don't have time to go slow."
The man snorted and tossed the iron rod toward him. "Here. Use this. It's heavier than whatever you had before. Feel the weight. Learn to control it instead of swinging wild like an idiot."
Kael caught the rod. It was heavy. His arms complained right away. The inner energy pulsed in his chest as he gripped it tighter. He started swinging it slow at first, then faster. The extra weight forced him to use his whole body. The Echo responded. The Instinct Echo helped him keep better balance. The Determination Echo pushed him to keep going even when the pain got worse. He could feel the spark mixing with the Resonance — it made the rod feel a little lighter, the swings a little stronger.
But he pushed too far.
Late in the afternoon, Kael tried a full-power strike on one of the old dummies. He pulled on the inner energy hard, remembering that last desperate hit in the tunnel. He mixed it with the new Echo, focusing everything he had. The rod smashed into the dummy with a loud crack that echoed through the warehouse.
Then pain exploded in his side.
One of the deep cuts reopened wide. Blood soaked through the bandages fast. His vision blurred. The iron rod slipped from his numb fingers and hit the concrete floor with a heavy clang.
Kael dropped to one knee. His chest heaved. Black spots filled his eyes. The pain was so bad he almost couldn't breathe. His whole body trembled. The inner energy felt scattered now, drained and weak, just like his stamina.
Not again… I'm still too weak. Even with the Echo and the spark, I break so easily.
The older hunter shook his head. "See? That's what happens when you rush. You got some kind of hidden energy in you, kid — I can see it in the way you move — but you're not ready to use it like that. Go home. Come back when you're not falling apart."
Kael stayed on his knee for a long time. He didn't get up right away. The doubt hit him hard. He had pushed himself and failed. Again. The inner energy that had saved him before now felt useless if he couldn't control it.
That night, back in his small room, Kael lay on the thin mattress staring at the ceiling. His body was on fire. The reopened wounds throbbed with every heartbeat. He could barely move without pain shooting through him. He hadn't eaten much all day. Exhaustion pulled at him like heavy chains.
But the Echo kept pulsing quietly inside his chest. The spark was still there too — faint but steady, mixing with the Resonance.
He thought about everything. The first monster in the rainy alley, when the spark first woke up and made him swing that pipe. The scavenger on the street. The burrower guardian in the dark tunnel. The shadow beast with Rylan. Every single time he had been scared, outmatched, bleeding, and hurting.
And every time, he had refused to run away.
Something burned in his chest, hotter than the pain.
"I almost died again today," Kael whispered to the empty room. "Because I'm still not strong enough. Because I pushed too hard without control. The inner energy… the spark… it's growing with the Echo, but I'm still weak."
He forced himself to sit up slowly, ignoring the fresh pain that flared up. His hands shook as he clenched them into fists.
"Never again. I won't stay weak like this. The Echo is part of me now. The spark is part of me. I'll feed them every bit of pain, every failure, every drop of blood if that's what it takes. But I will get stronger. No matter what."
The blue window pulsed a little brighter in front of him.
Resonance increased.

Determination Echo grew slightly.
Inner Energy and Echo now linked. Minor amplification when focused.
Kael didn't feel happy. He just lay back down, breathing through the pain.
Growth hurt. It was messy and ugly. It left him broken on the floor after training, bleeding again, doubting himself. But he made a choice right there in the dark.
He would keep paying the price.
No matter how much it hurt.
No matter how long it took.
Outside his window, in the dark rooftops of Shira City, the golden eyes watched again. They had seen the training. They had seen the blood and the fall. They had seen the faint blue glow through the cracked glass.
And they were becoming more interested in the weak boy who kept refusing to stay down.
The real tests were only beginning.
