The Laziest System: Sign-Up System

"Sky Dragon's Claw!"

I swing my leg and release three massive sharp winds at Orochi. The serpentine dragon opens its mouth and creates a magic circle to block my attack. However, with him focusing on me, Yasaka releases a beam of fire at the dragon, and it lands a clean hit.

With Orochi getting distracted by Yasaka's attack, I fly to the sky, take a deep breath, and do a dive kick toward the dragon.

"Sky Dragon's Dive!"

Orochi raises his claws and blocks my attack. He then grabs my leg and throws me to the ground. A crack appears on the ground from the impact of my body meeting the ground. I take a deep breath and let my Sky Dragon Slayer magic heal my body. I also use Natural Energy to boost the healing process.

After a few seconds of healing, I'm ready to fight once again. I run toward the battlefield and see five of the eleven people are injured. I take a deep breath, gather as much air as possible, and clap my hands.

"Sky Dragon's Breath!"

I open my arms and release a gust of wind around the battlefield. The people that are injured start to heal up at a faster rate. The wind that I release is imbued with healing properties, and as long as I keep pumping some mana into this spell, I can heal people constantly.

After healing them all, I jump to the sky and roar.

"Sky Dragon's Roar!"

After releasing a torrent of wind, I did not stop there. I fly at Orochi and follow the previous attack with another one.

"Sky Dragon's Dive!"

I hit Orochi from the side and moved his body enough for him to lose his concentration fighting against Yasaka. Orochi looks at me with a hateful gaze and roars.

I take a deep breath and release a torrent of wind.

"Sky Dragon's Roar!"

Our attack collides, and this time, his attack destroys mine. It did not even last for a minute before his roar destroyed mine.

|This is bad|

'What do you mean, Grandeeney?'

|That dragon polluted the air around us. As a Sky Dragon Slayer, you will get stronger if you 'eat' clean air. However, the opposite can happen. If you take too much polluted air, you will get weaker and can be to the point of not being able to use your magic.|

'That is why my previous attack cannot handle that roar.'

|No. That dragon uses even more power to fight your roar. However, the air also affects your performance. At the moment? It is not much, but if you fight for another ten to fifteen minutes, you will be weaker and get sick if it is more than thirty minutes.|

'That means I need to hurry up.'

|Yes|

I nod and prepare to release my ultimate attack. An attack that I have been working on with Grandeeney. It is still a work in progress, but I need to try. 

I focus all my magic on the palm of my hand. I create a thousand compressed winds on my palm and use my Senjutsu to stabilize the spell. After a couple of minutes of concentration, a ball made of wind and Senjutsu appeared on my palm.

This is not an original technique. Naruto's Rasenshuriken heavily inspires this attack. Naruto needed chakra to create this attack and use Senjutsu to make it even more stable. I did not need chakra as I have magic and can directly control the wind from my Sky Dragon Slayer magic. Lastly, I get perfect control over my magic because of the system.

I jump a few steps because of my cheat, unlike Naruto, who needs to start from the bottom.

I keep feeding the rotating ball of magic and Senjutsu and see it grow larger and larger. The wind rotating around it gets even faster as it absorbs even more wind from its rotation. It is just like a black hole. The more it rotates, the more it feeds the wind around it. The more it eats, the faster and more powerful this attack will be.

|Quickly! You need to throw that thing! Your hand cannot handle it!|

I snap from my thoughts when I hear Grandeeney's voice. She is right. Just like Naruto's Rasenshuriken, it can damage my hand if I do not quickly throw this attack. Even Senjutsu has its limit of how much damage it can protect from my own attack.

With my attack in hand, I jump high and see Orochi focusing on blocking and attacking Yasaka. I see my chances and throw my attack at the Evil Dragon.

"Take this! Sky Dragon's Maelstrom Sphere!"

Orochi looks at me and sees the incoming attack. He creates a massive magic circle, but that is the wrong move. My attack hit his magic circle and exploded. It produces a vortex of wind in the immediate area. Within this vortex, countless microscopic wind blades are created.

These microscopic wind blades can cut through Orochi's scale because of the nature of my magic. It is a Dragon Slayer magic and is the bane of all dragons if used correctly.

I can see Orochi's entire body get sucked by the vortex. The vortex is now in full swing. Yasaka changes back to her human form and lands next to me.

"What kind of attack is that?"

"My most powerful attack. The explosion is not the biggest thing but rather what is happening inside the vortex. There are wind blades inside of that vortex that are stabbing and cutting Orochi at once."

After a minute of rotating, it stops, and I wait for the dust to settle.

"You gotta be kidding me."

After the dust disappears, I see Orochi, with almost ninety percent of his body destroyed. However, he is still floating in the air, and I can see his eyes looking at me with untold anger. He roars to the sky, and I can feel his strength increase by ten times.

"He is getting into Outrage mode! Ryan! Get out of here! I will hold him back! Take care of Kunou for me."

Before I can say something, Yasaka changes back into her nine-tailed fox. I grit my teeth in frustration. If only I had more power. If only I had more power to kill that dragon! Dammit! Why?!

I grit my teeth and try to run after her. However, my body gets weaker as the air gets even more polluted by Orochi's venom. Is this all I can do? Dammit. What a useless man I am. I cannot even protect the woman I like.

|Let me help you, Ryan.|

'Grandeeney?'

|I will lend you my power. I can lend you my strength with the same connection as my daughter.|

'Do it'

|Hear me first. While you have the same connection to me as my daughter, it is still different. If my daughter needs my help, it will absorb my life energy. However, instead of my life energy, you will fuel this power using your life energy.|

'Do it. I don't care. As long as I can help Yasaka, I'm willing to use my life energy.'

|Very well. Then go. Show the world the power of Sky Dragon Queen.|

I can feel it. I can feel a tremendous amount of power coursing through my body. I look up and see a silhouette of Grandeeney roar above me. The silhouette gets absorbed by me, and I look at Orochi, who looks at me instead of Yasaka. He now ignores her completely and takes her attack without care.

I look at my body and see the scale from Dragon Force spread to all my body other than my face. I can see a tail coming out of my butt and a pair of wings coming out of my back. I shake my head and focus on the dragon that is ready to attack me.

"Orochi!"

I take a low stance and start to run toward the Venom Dragon. I can hear him roar and fly at me. I jump and appear in front of his head. I do a dive kick at him, but this time, a large amount of wind around me creates a drill that is ready to pierce anything in its path.

"Wrath of Sky Dragon Queen!"

I fly at Orochi at full speed, and I can see the forest around me get ripped apart by the chaotic wind around me. Orochi flies to me, head first, with all of his energy focusing on his head. This will be our last attack.

A second later, our attack collides and creates a massive explosion.

*BOOM*
