Invicinble Colorless Butler

The green dragon was many times bigger than the wyvern. He has a shape like a western dragon. He has hands and feet and large wings on his back. His entire skin was covered in green scales which were many times tougher than a wyvern and had sharper fangs and claws. The green dragon belongs to the category of superior-level magical beasts. His fighting ability was on par with demigods. He has the skill 'Spawn Subordinates' which can revive his subordinates within a certain time as long as one of his subordinates is still alive.

Right now the green dragon was on a rampage because all of his subordinates had died. He vented his anger on the two people who were currently fighting against him. All the wounds he received from the fight with King Leonida and Merlick healed instantly.

"Merlick, at this rate we'll run out of energy first." King Leonida looks out of breath. He kept moving to dodge the attacks from the green dragon..

[Fire Tornado]

Merlick created the Tornado from a combination of fire and wind elements. Even though the green dragon was hit directly and was in the center of the tornado, he seemed to ignore the wound and continued to attack them.

Roooooaaaaaaaaaaaaarrrrrrrrr...

[Cross Blade]

King Leonida made consecutive cross slashes on the green dragon's chest. But he managed to dodge it even though it hit one of his wings. It didn't take long for the wound to close by itself.

"Ridiculous! He continuously regenerates as if he has no limits!" Merlick was surprised to see the wound on the green dragon's wing heal quickly. Since the beginning of the battle, the green dragon has always been hit and injured, but the wound always heals by itself. His regeneration seemed limitless and too fast.

"Merlick, can you hold him for 1 minute? I'll finish with my full strength." King Leonida had already used almost all of his skills, but the injured green dragon quickly regenerated. So he needed a stronger finishing attack. He had one on his skill list.

"I will try it." He nodded slightly then took out a magic wand with a 4-colored crystal on it. He opened 8 magic circles on his body, and thick mana radiated from him.

[4 Element Pillars]

From the 4 corners formed 4 great pillars of fire, wind, earth, and water. The 4 pillars moved and pinned the green dragon in the center. The green dragon rebelled and tried to get out of there. He flew up but the 4 pillars turned out to be connected.

While the green dragon was pinched by Merlick's magic spell, King Leonida brandished his Claimh Solais with both hands. He opened his 8 crown patterned aura seals. The golden aura was compressed in the Claimh Solais. Little by little its aura grew thicker and Claimh Solais let out a projection of itself above the green dragon.

[Sword Obelisk]

A clone of Claimh Solais with a giant size was created on it. A huge golden sword that is even bigger than the body of the green dragon. King Leonida swung his sword at the green dragon and the giant sword Claimh Solais was falling at high speed towards the green dragon.

The green dragon who realized the danger immediately struggled with all his might to escape Merlick's 4 element cage, but his efforts were in vain. Because he knew he couldn't get out of there, the green dragon opened his mouth and aimed it at the giant sword Claimh Solais. He did the same as what Seiryu did before.

[Dragon Breath]

In contrast to Seiryu which shoots out compressed and concentrated energy at a single point like a laser. The green dragon shoots his breath with a fairly wide range.

The collision between dragon breath and giant sword Claimh Solais occurred in midair. They pushed each other. But the green dragon's breath was gradually pushed away and the sword finally hit him.

Boooooooommmmmm

The shockwave occurred due to the giant sword Claimh Solaish's attack on the green dragon. Even the Magic Train that was some distance away shook from the impact. But just as King Leonida wanted to breathe a sigh of relief, something shot out of the smoke. The green dragon that he thought was dead was currently right in front of him and opened his jaws and was ready to bite him.

"Leo!" Merlick who was a bit far from King Leonida did not have time to help him.

King Leonida immediately swung Claimh Solais at the green dragon fangs. He used the momentum of the fangs to bounce himself off and keep his distance from the green dragon.

"Fortunately I acted quickly. Otherwise, I might have been inside the monster's belly." King Leonida still can't calm down because the green dragon is still alive even though his body is full of wounds. And what shocked him the most was that the green dragon's severe wound healed quickly after being hit by his final blow.

"Leo, are you okay?" Merlick approached King Leonida after seeing him bounce off the green dragon's attack.

"I'm fine. Luckily I acted quickly beforehand. I lowered my guard when I thought my attack was successful." King Leonida took a deep breath to relieve his tension.

"No, your previous attack was successful. It's just that the monster has abnormal regeneration. We can't go on like this. Otherwise, we will lose." Merlick looked at the green dragon which was now fully healed from the injury he had received from King Leonida.

"You're right, but we won't have time to think of a way to kill him. He's coming, Merlick!" He shouted at Merlick after seeing the green dragon flying towards them at high speed.

From the start of the fight, they were already at a disadvantage from fighting in the sky. King Leonida or Merlick weren't good at aerial combat. The green dragon closed the distance with them in an instant. He planned to bite Merlick and King Leonida to pieces.

King Leonida and Merlick immediately dodged the bite. They split up and intended to attack him together. But the green dragon twisted its body and wagged his tail at them. King Leonida and Merlick were blown away by the lashes of his tails. They both had serious fractures. If they weren't at the level of a saint or sage, they would probably be dead. But the green dragon doesn't seem to be chasing them, he shoots dozens of fireballs at them both from a distance.

Both of them resignedly accepted the fireball as they were currently unable to move due to the lash from the green dragon's tail.

[Ice Wall]

[Water Umbrella]

The fireball attack heading towards Merlick was blocked by the wall of ice and the one heading towards King Leonida was blocked by a large umbrella made of water.

"Principal! Are you all right?" Beatrix approached Merlick who looked like he was about to fall from the sky. Behind her are Kalya and Flavio. Christof and Ashley help King Leonida, while Reid and Alvis tried to restrain the green dragon.

"Oh, I'm fine. Good thing you came on time. Thank you." Merlick was still struggling to speak, he looks in pain while holding his chest.

"You don't have to think about it. Then what about the green dragon?" Flavio who saw Merlick in pain immediately supported him. Then he used a healing spell on Merlick.

[Major Heal]

The pain in Merlick's chest slowly healed, His normal rosy face had returned from being pale before.

"Thanks, I'm fine now. For that green dragon, it looks like we have to kill it in one hit." Merlick began to narrate his fight with the green dragon. They listened intently to Merlick's story.

"Is that so... It's troublesome against an enemy that doesn't have a regeneration limit." Flavio became gloomy after hearing Merlick's story. Not long after that, King Leonida came along with Christof and Ashley.

"Leo, how's your wound?" Merlick asked him whose face was still pale.

"I'm fine, it looks like you have also been healed. We must immediately help the other teachers who are holding back the green dragon. They don't seem to be able to last much longer." King Leonida looked at the green dragon who was chasing Alvis and Reid. He flew there followed by Merlick and the others.

[Shadow Binding]

[Fire king Incarnation]

Alvis cast a black shadow over the green dragon's body and restrained his movement and Reid swung his sword at him. His slash turned into a flame-robed human figure and shot towards the green dragon's face.

Roooooaaaaaaaaaaaaarrrrrrrrr

The scorched green dragon's face slowly healed.

"What!? Isn't this fight endless if it continues like this!" Reid was shocked that his strongest attack didn't even work on him.

[Water Jail]

[Fozen World]

The green dragon's body was wrapped in a gigantic ice ball from Beatrix and Christof's combined attack. Merlick, King Leonida, and the other teachers came from behind them.

"Alvis, Reid, we have to attack him with full force at the same time. Now is our chance as he is temporarily unable to move." Merlick gave orders to all the teachers. They all nodded in response. They began to bring out their full strength. The aura and mana they emitted even distorted the surrounding space.

[Ice Fire Harmony]

[Fire King Incarnation]

[Energy Bomb]

[Corrosion Breath]

[Tempest Arrows]

[Steam Explosion]

[Light of Destruction]

[Sword Obelisk]

[4 Element Blast]

Booooooooooooooommmmmmmm...

A tremendous explosion occurred in the sky as a result of their combined power. The shockwave even shook the Magic Train which was quite far from their battleground. Thick smoke covered the place where the green dragon was. Therefore, they did not know whether the green dragon was dead or not.

"Did we manage to kill him?" Reid who saw their attack hit the green dragon asked anxiously. But before anyone could answer, there was a roar from within the smoke.

Roooooaaaaaaaaaaaaarrrrrrrrr...

His roar even blew smoke around him. He was so badly injured that one of his wings was missing. But little by little the wings grew back.

"Impossible! How can he not die!?" Ashley couldn't believe what her eyes saw.

"So how do we kill him?" Flavio asked Merlick and King Leonida who currently had gloomy faces.

(Ziel, I know you saw this. But can you help this time?)

Kalya suddenly spoke in her mind. She didn't know why she was doing this, but her feeling was sure that he was looking at her right now.

(You can kill her. Join Silphy and ask them to buy time for you)

Ziel's voice came to reply to Kalya's hope.

(Hehe... I know you saw it. Well, I'll do it. So what should I do after that?)

She smiled without realizing it and was seen by Beatrix who was standing next to her. When she realized it, she immediately returned to her cold face.

(Use arrow attacks when you fight against me. The third function of your ring will activate by itself. Coincidentally the elements match you)

Ziel started explaining how to kill the green dragon to her.

(Okay! Silphy!)

(I've been waiting!)

Silphy then manifested herself in front of everyone.

"Miss Kalya, that is?" King Leonida asked her curiously.

"I don't have time to explain. But can you guys keep the green dragon busy for 3 minutes? I want to try something." Kalya looked at Merlick and the other teachers.

They did not immediately answer because they were confused by Kalya's request.

"What do you want..." Merlick wanted to ask what Kalya would do. but he immediately stopped his words. He was sure that Kalya had a reason for saying that. Since they had no other choice, they finally nodded in agreement.

Then in front of them, Kalya joined Silphy. The uniform she was wearing changed into emerald armor like a Princess knight and behind her floated a large spirit circle. Everyone was stunned at Kalya's current appearance, but they couldn't admire it for long after hearing the green dragon's roar. They rush to hold him as per Kalya's request.

Kalya made a bow with spiritism and aimed it at the green dragon. She drew her bowstring and a wind elemental arrow was created. It didn't stop there, the ring on her finger emitted gray light accompanied by a spark of red lightning. Kalya's arrows are shrouded in red lightning compression.

"This..." Kalya was shocked to see it but then smiled after remembering what Ziel said that her element matched her. Then she shot her arrow.

[[Thunderstorm Dragon]]

The arrow turned into a small Seiryu which shot out at incredible speed and pierced through the green dragon's scales.
