Reincarnated as an Energy with a System

The Sparrow flew high in the sky with green mist coming off of it. "I see… The beetle is out of the fight. That means there is nobody there to protect your master, right? Hahahaha!" it started laughing. 

The green mist coming off of it suddenly shot out towards Night who had been on edge, ready to stop him if he made a move towards Ning. 

The mists changed forward to appear as thousands of birds that flew towards Night. Night flapped his wings and sent out many feathers that flew towards the birds of mist. 

The moment they collided, they created a small explosion. The mist birds suddenly changed into bursts of winds that tried to rip apart at the feathers that were shot out, and actually managed to tear a few of them quite easily. 

Through the explosion, the sparrow flew towards Ning, trying to take advantage of the situation. However, Night had been ready again and hit the sparrow in time once more. 

The sparrow sent out the mist birds, and Night sent out more feathers. The small explosions that occurred once again leveled the playing field. 

Night looked at the sparrow coldly and decided to go on the attack himself this time. He disappeared with the flap of a wing, but so did the sparrow. 

The sky had streaks of green that made it seem like the sparrow was the only one flying, however, anyone that used divine sense to check could see that Night was right by the sparrow, attacking it with his sharp wings and talons at every move. 

While the Sparrow was faster than Night, Night's movement was more smooth, as if the night was its domain. The sparrow frowned after dodging hundreds of attacks. 

Suddenly, it sent out a massive gust of winds to create a pocket of free time for itself, and it worked. Night who was caught in the massive gust of wind couldn't continue his onslaught of attacks. 

The sparrow used its small window of opportunity very carefully. Green mists no longer appeared from its body, and it was instead all green light. 

The wings suddenly straightened up to be at the longest wingspan possible. Then, instead of flapping like a normal bird, it started flapping its wings like an insect. 

The wings flapped up and down without bending even a little. It started off slow, but within a few seconds, it reached the point where all one could see was a few green lights here and there. 

Night saw this and frowned. He didn't understand what the bird was doing, but suddenly, a very high-pitched sound rang out from the sparrow. 

It was screaming, and the flapping of its wings amplified the sound to the point where Night started getting disoriented. All of a sudden, it was like he was paralyzed and stopped flying. He then started plummeting down to the ground, while the Sparrow now had a free pathway towards Ning.

Blue was singlehandedly stopping the rest of the beasts from going up the mountain. They couldn't damage him or go past him now that he was trying really hard to stop them all.

The Turtle couldn't hurt him at all, and Blue couldn't hurt the turtle. So they were practically at a standstill and needed something else to happen before the fight could go either way. 

Ning's aura increased more and he was halfway through the breakthrough. Once more of the core was cracked, the rest would become very easy. That was if nobody tried to interfere with the breakthrough.

Blue was pretty confident that Ning could easily breakthrough within a few minutes now and he just had to keep them away for just a little longer. 

The turtle could see this too. "I know! I know! I'm trying. But I can't hurt this flood dragon at all. I might have to try a different tactic," the turtle spoke out. 

That caught Blue's attention. "Who are you talking to?" he asked. 

"None of your business," the turtle shouted from inside of its shell. Then, it popped out its head from within. 

"What the hell?" Blue shouted when he saw the head. The turtle had a really long head with crystalline spikes on top of it similar to the crystals growing on its back.

"If water does nothing against you, then I will beat you to death with my own head," the turtle said as it started waving its giant head left and right. 

******

Night fell through the darkness as he plummeted to the ground. He hit the barren land with a very high impact that shot out dust all around him. 

The disorienting sounds stopped him from being able to tell what was where and thus wasn't able to fly properly. 

He quickly got up from the ground, clearly undamaged, and looked towards the Sparrow, who had already stopped the weird wing maneuver and was flapping its wings normally to attack Ning. 

"No!" Night shouted and jumped up in the air before flying towards Ning, but it was too late. The Sparrow was already in front of Ning. 

"Yes, I understand," the Sparrow suddenly spoke out and increased its speed to the extreme as it used its wings to try and decapitate Ning. 

However, just before the sparrow reached Ning, it suddenly stopped. It tried to move, but it couldn't make any movements. 

"What?" it said in shock.

Just then, Ning's entire body vibrated as sound spread out from every surface of his body. "You might have been able to kill me if I was a normal human right now— "

The sparrow got scared. "How are you able to split your attention?! You are in the middle of a breakthrough," it shouted. 

"— However, I am not something you can fight. Even going against me means your death is now sealed. Whether the executioner is me or somebody else however is a different question."

The sparrow was suddenly let go of, and it flew up in the air. Then, it turned around and got face to face with the angry, dark eyes of Night. 

*****

The turtle's head was starting to get bloody by now. However, that was not its own blood. Blue body was starting to get battered and tattered from the continuous attacks from the crystal spikes that the turtle had. 

Blue also tried attacking back, but the turtle had just too good of defense to take any damage. Also, now that his scales were broken and the inner flesh was visible, the minor beasts hiding behind the turtle were starting to do small, but considerable damage. 

He tried to kill the other beasts at least, but they were all hiding behind the turtle and didn't take any damage at all. Blue was beyond angry at this point.

"Fine, you want to play dirty, then I will do so," he said and suddenly started spinning around the ground to create a large cavity big enough for him to stay in. 

The turtle was surprised and a little confused as to what he was doing but didn't stop its attacks. The crystals on its head were the only thing strong enough to damage blue and it damn well made sure he knew it.

BANG BANG BANG

Continuous hits from the turtle could be heard while Blue finally finished the hole in the ground. Then suddenly, he spat out tons and tons of water into the hole. Once it was full, he plunged into it. 

The turtle didn't really understand what was going on, but it kept on attacking. "Huh?" then it stopped. 

The water wasn't being filled with blood at all, despite the flood dragon having wounds all over its body. 

"What's going on? Did the flood dragon die ins—"

Sprout of water shot off into the sky as Blue finally showed himself again. Only this time, he wasn't bloody at all. In fact, he didn't have any wounds at all. All of his scales were back to normal, and the blood was all gone. 

"Wha— What's going on? Where are your wounds??" The turtle asked in fear. 

Steam started appearing around Blue as a blue glow shined. His incredibly angry face struck fear in the heart of his enemies. 

"I… am descended from the mighty True Dragons, and hold their essence in my body. Did you truly think you could ever win against me?" he shouted with a terrifying aura around him. 

Suddenly, his aura changed. His aura shifted from that of a flood dragon to that of something distant, something ancient, something terrifying, something that reigned over all. 

The turtle and the rest of the beasts were made to stay at a single place as the terrifying aura engulfed them. Their fear didn't allow them to move at all. 

The steam around blue changed form as it gathered around blue. Some formed giant wings around him, some formed longhorns. Some gathered to form long legs around Blue's body and some formed to make better glistening scales. 

"G-God!" The turtle said in terror. 

"So you finally know," Blue said. Suddenly, he sucked in the air into his lungs. It felt like he took a split second to suck in all the air in the surrounding, but it also felt like he took an eternity. 

"I— I don't think I can do what you ask," the turtle mumbled by himself. 

PHOOOO

Blue shot out water that directly hit the turtle. The turtle didn't take any damage from water at all, absolutely zero. However, what was being shot at it wasn't just normal water anymore. 

This attack had breath in it. The breath of a flood dragon, empowered by a single drop of a True Dragon's essence. It was equivalent to a True Dragon itself using their dragon breaths. 

So, the moment the breath hit the turtle, its head was crushed to pieces along with the crystals on it, followed by the crystals on its shell and finally, its entire shell itself.

However, that was not where the breath stopped. It went further from that and hit the rest of the beasts, killing them all in a single attack. 

Only when they were all dead did Blue finally stop. The steam around him vanished and the glow disappeared as well. He huffed very loudly, to the point where he could faint at any moment. However, he stopped himself from doing so and instead flew up to the top of the mountain, when suddenly he lost all sight. 

*****

A black aura with a white outline, similar to the fire that burned from him, appeared around Night. The sparrow was scared when it felt the aura that appeared around him. 

"Wh- What are you? This… this is not the power of a Dark Emperor Eagle at all," it shouted. 

Night, however, did not answer anything. Instead, his aura reached a peak and suddenly, everything around him suddenly got dark. 

"What? I can't see!" the sparrow screamed. Until now, due to the fact that it was, 3 am in the night, and the presence of Night himself, the area in the mountain was clad in darkness. 

The only way any of them saw anything was by using their divine sense that went as far as a few kilometers away. 

However, with what Night had just done, nobody could see even with their divine sense. The Sparrow, who was the closest to him felt like he was truly blind for the first time in forever. 

Suddenly, the sparrow sensed the change in the air around it, and it knew that Night had moved. It suddenly ducked but still got hit in the back of its head. Blood gushed out of its head, but the would wasn't close to being fatal. 

The sparrow got scared. Night was invisible to the sparrow, and as one of the greatest hunters, he could easily fly around without making a single sound. 

The sparrow tried flying away, but it couldn't see where Night was at all, so it took damage from all directions. 

A cut to the forehead, a scratch on its wings, a peck to the back, an air slash to the chests. The sparrow was attacked from left and right and finally fell to the ground half-dead.

Even on its deathbed, it didn't know what had happened at all. Its wings were all destroyed and blood left its body at a rapid rate. Without any assistance from outside, it would be dead in less than a minute.

It stirred a little to muster away enough energy to send its Nascent Soul flying away. As long as the soul survived, it could find itself a new body, or even make someone create one for itself. But just then feathers fell on both the soul and the body. 

Black flame erupted out of nowhere that burned both the soul and the body. The sparrow screamed for just a second before its voice disappeared onto the other side. 

When the flame disappeared, not even ashes remained. 

The darkness left its veil, and Night's weak body drifted down on the top of the mountain, next to where the Aegis and Blue were currently resting. 

They looked down on the empty expanse with no beasts and were relieved that they managed to protect Ning till the end when suddenly, another aura erupted elsewhere.. Apparently, there was one more enemy to fight.
