Chapter 8: Modification

"Rosie. It's good to see you here."

Welkin greeted his former teammate. It's been years since their final mission and their part away to live their own lives.

"The same to you, Welkin, though I'm not happy to see you being the commander." Rosie frowned a bit.

"Why?"

"Isn't it obvious? I'm afraid that your curiosity of bug would affect to others soldiers."

"Hey! It's not that bad to learn something strange and new!"

Elsword and Rossa were standing while watching those two arguing something that they did not understand.

"Etou… what are they talking about?"

"Beat me…"

Soon their argument came to the end and then turned to the duo.

"Ah, I forgot to fully introduce her, Elsword. Her fully name is Brigitte Rosie Stark, former shocktrooper of Gaia Millitia. She's been with me as former member of Team 7."

"Stark? But her last name is different from Rossa's."

"She's my adopted daughter, Sieghart-san." Rosie explained "I have been adopting her since after the last war ended. She was the victim of Gaia amd Empire's War that took her family away. I couldn't bear to witness this so I decided to take care of her."

Elsword nodded in understandable. Joining the war had listed them as the victims of war that we had to win by paying their lives. The villagers had to we involved with it forcefully and may cost their own too by the greed and wish for conquest. That's the thing he didn't like.

He tensed up a bit upon feeling Rosie's hard gaze toward. From the look of it, he could read the familiar feeling of a parent to their child.

'Ah here come the old question.'

"Let me ask you again, what's your relationship with my daughter?"

"I told you, we are comrades!"

But Rosie didn't buy it. She knew her daughter well. Rossa's body acted differently when standing near Elsword, like it looked more… girly. Plus her eyes kept glaring at Elsword a few times, a sign of a girl having a crush.

Things would have been more intense had Welkin not inteferred soon.

"Maa maa, Rosie. Leave them alone. Why are you here?"

"I have a call from the Gaia that we have a big threat to her army. Is it true?"

"Yes, but this is far more dangeous than we have faced. The Empire has acquired the Former Valkyrur and Eltron. They are planning to use them to attack Gaia. You gonna join the war again? even not long after you retired?"

"Absolutely, do you think I can stand here and watch them taking innocent people's lives away?" Rosie slammed her fist on the table with fierce determination, which Welkin smiled"

"Well then, welcome back to Gaia. Rosie."

With how annoying Rosie was to him, he decided to head for the factory with his sword on his back. There, he met Isara who was focusing on maintenance of the aircraft. He had a plan to find her to help him modifying his sword since it was using only the El energy to operate the flame engine.

"Yo, Isara-san."

The girl turned around and found the red haired knight heading toward her.

"Elsword-san."

She jumped off the aircraft and ran toward him. Elsword pulled his sword and placed it on the forge nearby, got Isara curious.

"You need something?"

"Ah, yes. One thing." Elsword said as he pulled out his blueprint of the sword "I need a modification on it."

Isara was confused at his request until he gave her the blueprint. She rolled it open and watched it for a long time to research. The first thought crossed her mind was incredible. It's simple but enough to cause destruction. The engine was put near the handle 5cm away with the handle as trigger by twisting it. Multiple lines attached to the engine spread widely inside the sword while the sword itself as cover to protect the inner engine.

When twisting, the handle made a friction effect to the small wires and transferred the energy to the main engine, which emitted abnormal heat to the sword to the point it spread fire. The sword was made with unidentified material in her world but if Elsword trusted his sword, the material itself can withstand the high temperature.

The weapon he wielded would enough to destroy a medium tank if he can make a clean cut directly where the ammunition and burnt with fire.

But the question was, why would he request her of remodification?

"Why would you need me to change your weapon when it can destroy a tank?"

"Ah, you see. That sword requires amount of El energy to operate the flame. The handle was where it pulled my power. You know that I'm away from home. I can't recover El energy as fast as I could so I rarely use my sword at its full potential."

"So that's why you need me to modify it?"

Elsword nodded. Isara kept staring at it while thinking of the way to increase its strength. The main problem was the energy. Surely he could use it but not often. It's a downward if using outside. What if it can operate with Ragnite, the essential material in Gaia? No, Elsword was El User. If he tried to absorb Ragnite directly, it would lead him to certain death due to energy conflict.

But what if she put Ragnite in another way?

A small idea popped up, but was put aside as she needed to know how to insert that material inside the sword. Her eyes then shifted to the blueprint of the medium tank, its cannon specifically.

"… THAT IT!"

"?!"

Elsword was surprised by her sudden scream.

"Elsword, I will need your hands for this."

"A-Ah Haii…"

They both began working on it. Isara told him to dismantle his sword, which got Elsword hurt just by hearing it, and worse when he had to do it by himself and watched it. In the end, he managed to dismantle it, though he cried over his sword's scatter pieces with 'good bye, my sword. I will get you back' thought.

Isara just giggled at his childish act.

She put a new blueprint and began drawing the weapon in her opinion. Elsword watched hẻ drawing and slowly uderstood what she meant. He also added his idea into

He picked the pieces of the sword and forged it into another shape for the blueprint. The girl was amazed by how skillful his hand was. The forged piece was heated up multiple times to keep the temperature high for him to reshape. It took hour to make it as they wanted and put it in the water that caused sound of hot water bubbles to complete the forge.

Isara used every tool to merge the pieces together, marked the place with marker and use the drill to put a hole on it, reshaping it again with friction machine. A smile appeared on her lips at the piece she had completed.

The girl told Elsword to try and activate the engine using his El energy. He touched the handle and twisted it to heat it up while Isara examined. She tried to put the Ragnite near the engine which resulted in shutting down due to energy conflict. That made her thought of the amount of energy. She measured the input of El Energy and Ragnite Energy at the same amount. She told Elsword to channel his power inside the capsule which he did. Isara then put the same quantity of Ragnite equal to El Energy.

*Bam!*

"!"

"Kyaa!"

As the result, it exploded. Elsword quickly hugged Isara and protected her from the explosion. Elsword had to bear the extreme heat on his back due to the explosion. He uncovered his hands to see the girl was fine, though their faces were staring each other. Isara was the first one pushing him away with her blush on her face, embarrassed by how close they were, her heart was jumping.

A moment later, Isara's flush face was gone and noted it down, learning that the Ragnite and El caused blue explosion due to the balance input. She learned that if the input was imbalanced, nothing happened as the most amount would dominated the small one and shattered it. She came up with making a large case of magazine and a customized 57.5mm shell. She planned to put Ragnite in it with a fixed amount in the half below of the bullet, the upper half will contain the metal bullet or a customized bullet which was inciderator or HE.

She had various experiment she wanted to try and that made her excited with his sword.

They forgot how much time had passed. The sky turned dark. Elsword focused on crafting final step to complete the weapon.

"Yosh… that should do it."

Elsword wiped his sweat off his forehead, smiling at the complete weapon. He put it on his back and turned around to find Isara sleeping on the table. She must be exhausted. The knight chuckled and carried her back to her home, where he met her brother who was writing something on his note.

"Elsword-san, oh Isara."

"She fell asleep so I carry her back."

"Arigatou."

Welkin helped Elsword carry her to her room for a while then he returned.

"You prepared for the war?"

"Isara helped me with modifying my weapon and needs to test it tomorrow. If thing goes smoothly as we expect, we have an advantage."

"Care to tell me what are you and Isara planning?" Welkin couldn't hide his curiosity and asked away.

"That… you will have to wait for tomorrow."

Elsword just smiled at him,

Because Isara wanted it as secret.

- Skirmish Battlefield -

Operation: Modification.

Elsword: Prototype Sword.

Elsword was standing with his sword on hand. Surrounding him were dummy and fake tank. Isara and other spectators watched Elsword prepared for the simulation. Welkin noticed the sword Elsword was using was… bigger than before. He wanted to ask his adopted sister what she and Elsword had done, but came to halt since she said that he should watch.

The sword design was nothing change except it's bigger and…

A mag?

"Let's go!"

Elsword charged forward to the first dummy battalion. They were armed with air guns to fire the silicon bullets, but that didn't mean he couldn't feel pain. He dodged them and swung his sword, cleaving them in halves.

"He's fast." Welkin commented "He can dodged them easily and take them down."

For the targets far away, he chanted fire balls and threw at them. He only used a small amount of El energy to distract them while approaching to cast finish blow. Elsword had to dodge a wave of bullets from another battalion and hid behind sandwall. In order to clear them, he had to use it. He twisted the handle, which drove the engine burning up in red color.

He slammed his sword on sandwall and pulled the trigger on his index finger. The head of the sword shot out wave of flame and burned the targets down, earning many gasps from the audiences.

"Incredible."

Elsword pulled the second trigger on his middle finger as the empty shell was ejected.

The next one was fake tank.

"Time to test it!"

He swung his sword behind. His back had a small device attached and scanned the rune symbol. The sword reacted and began transformation. He threw the sword in the air for the audiences to watch it carefully.

The handle turned 45 degree to the right and slid forward. The stock came out where the handle had been. Upper half of the sword extended longer and the width smaller as a cannon appeared, extended. Handgrip appeared below the sword along with trigger and another handle on the top of the sword.

Elsword caught the top handle and gripped the sword handle which was now the bolt (or lever) and ejected the empty shell inside the sword by pulling it backward and returned.

"Rune Buster Mode Activated!"

To test out the power of the gun, he charged forward the tank while his left hand held the upper handgrip and right hand on the bolt. It still served as the overdrive sword handle and had its function. He twisted it to burn the engine hot enough and back to hold the lower handgrip, index finger on the trigger. The symbol was oddly turned red and blue on both side of the gun. Once he approached enough gap between the tank and him, he raised the cannon to it and…

"Atomic Buster!"

The bullet was consumed in the burst of flame by engine and was spinning by the cause of spiral core. The flame burst pushed the flame bullet at a high speed, leaving the trait of flame in the air and pierced the armor of the tank. The heat of bullet was enough to penetrate past the whole tank where the ammunition was placed, if the tank was real one.

The bullet still travelled for a long path before it went explosion, blasting part of dirt.

Elsword pulled bolt to eject a red hot shell on the ground where the grass caught fire.

"Amazing… I have never seen this kind of weapon, not to mention the destruction could destroy a tank." Alicia was amazed. Rossa couldn't deny this and nodded.

The last trial had yet to finish. The last battalion charged in with knives and guns. Elsword couldn't turn the cannon back to sword form as it needed time to cooldown after the shot. He held the upper handgrip with left hand and twisted it vertically, forcing lower handgrip to go back inside the gun and pulling out another trigger near the bolt.

He swung the whole gun, slamming its stock on the first target's stomach and blasted them away, then he swung upward to use its cannon punch another's chin and took the empty mag during attack and inserted another one.

The audiences didn't know what he's planning untill they saw Elsword held the bolt with trigger and.

*Bang*

Spread shot came out from the cannon, destroying the android completely. Another android attacked him with a knife and was countered as Elsword dodged behind it. Turning the gun around, he used the bolt to hook it backward while thrusting his right elbow, breaking its neck and ejecting the 57.5mm shotgun shell and loaded new one.

Spinning the gun once again, he held it with both hand, charged forward that he pushed them back and bashed them in the air. The last shot destroyed them.

"Battle Stimulation: Finished!"

Elsword sighed in relief and beat tired. He fell on the ground, Rune Buster transformed back to Rune Sword, breathed heavily to regain his air.

"Elsword!"

Rossa ran to check on her crush(?), worriness filled in her.

"I'm… good, Rossa. Nothing went wrong." He grinned through his breaths "Operation: Modification, success."

The girl gave him a bottle of cold water who took and drank half of it while cooling his face with the remain. Isara went to check on the condition of the sword to see if any damage had done to it and the result shocked her. The sword was intact. Despite the extreme heat she put additionally to the sword, it was still durable.

The sword was added more weight due to addition cannon, yet he can control it as he would.

"Elsword, how can you control Buster? It should be heavier than before."

"Ha… i have a friend who prefers a giant cannon to fight than a sword and he got me in weight training. I learnt from him," He said, thinking of a certain Hamel Guardian in his mind.

"Let's talk about this friend of yours later, we need to get you back for treatment."

"I can go on my own- Oof!" Mio thrusted her elbow on his chest before he could deny, forcing him gasp.

"I don't take no for the answer, Elsword."

Elsword's arm wrapped on Mio's neck as Rossa did the same on the other hand since one girl alone couldn't lift him up.

"Ha… thank you…"

Welkin just chuckled. It seemed like Elsword had some sort of weakness when it came to girl. Rosie was still not getting used to seeing her daughter being with Elsword, but she had to. She saw Rossa's smile crept on her lips when talking with Elsword. It looked naturally.

However, the biggest problem was Welkin told her about him being with other woman name Eve and Mio. Despite that, Rossa still accepted and chased after Elsword. Many questions popped up in her mind, but the main one was… was he playing their hearts or genuinely loving them?

The next day, Elsword and Isara arrived at HQ, in Welkin's office. Isara presented the blueprint of Rune Buster to her brother as well as hearing Isara explained how it worked.

Quite a dangerous weapon he had.

But what he didn't understand was the kind of buillets it used.

"Then what ammunition it uses?"

"About that, it can use 57.5 shotgun shell, 57.5 HE bullet, 57.5 AP bullet and 57.5 Ragnite Bullet."

"Wait, what? Ragnite bullet?" Welkin was surprised.

Isara nodded happily and presented another blueprint of Ragnite Bullet.

"Though it's not an official name. The shell contained the Ragnite as ignition. Elsword's El energy will be transferred into the engine and burn it up. If the amount ratio of El and Ragnite are 1:1. The small bolt behind the shell will eject, letting the collision occurs. The force will be greater than any of gun powder can make. The bullet will burn hot and can penetrate armor tank like AP cannon can do a blue explosion after 5 to 7 second after shot. "

"Shotgun shell can only be used in sword mode and buster mode normal shot. If the engine is too hot, the bullet can be melted and stuck in the shell, thus ineffective. The same to HE bullet."

"Naruhodo… (I see) but don't you think it's too dangerous to wield it?"

"E heh heh… that why Isara forbids me to use Ragnite Bullet unless things become worse." Elsword grinned lightly "The risk of using it is getting me burnt if using without thinking twice."

Welkin nodded in approval. With that power and weapon Elsword had, he can stand a chance against Envy, but the cost may be great.

"Thank you for your details. I will have this to present to the Gaia Military, though I'm sure that Bloody would take it to make one for himself."

"That's not gonna happen, Welkin. The design is uinique only to be used by Elsword himself as most of the parts are in Elrios, his engine specifically. If he tries to make one, he only gets himself wounded before he can make first shot."

"I see, that's good to hear." Welkin smiled in satisfaction "By the way, I have something else for you."

"What is it?"

Welkin took out a letter with a red seal on it, attached with a red rose. Elsword read the seal and learnt that it's the royal one. His name was written on it. Isara gasped at it, knowing what he meant.

"The Queen has an eye on you, Elsword."

Yuu: It's kinda… shorter than last one. The Final Term is coming and I have to be prepared for the intership. The time for update could be longer (just addition day or 2 at most), if the new schedule didn't take much time.

Chung: Why are you using my fighting style?

Yuu: Why not? It looks cool in every way! *gleamy eyes*

Chung: E heh heh, you think so? *slightly blush*

Yuu: Anyway, read and reeview, please OwO /

Chung: Good luck on your exam, bro.

Yuu: I will T^T...
