"Out of the way! Out of the way!"

*Bam!*

...

"Ouch ouch ouch… Rose! Why do you have to crash on me?!"

"I'm… sorry…"

… Ah… Poor our protagonist. He had to bear with the impact Rose caused on him.

"How many times I told you, go to the empty field and test your gear there." Elsword scolded as he pulled her up from the crater the blonde caused.

"I tried, but my Nitro Motor just pushed me out of it and… you know… Ehehehe…" Rose giggled in nervous.

Let just say, Rose (Minerva) was trying to boost the Nitro Motor to increase its capacity and mobile in battlefield. This time she added more fuel and released a lot more power, too much. As the result, the motor pushed her away from the field and (by coincidentally) crashed on Elsword (Knight Emperor). It was not the first case that she crashed onto him. He had to bear with the failed experiment she tried on her motor and received several crashes from her.

"Anyway, fail again?" Elsword asked casually, knowing that if she crashed on him, her experiment failed for sure.

Rose nodded and sighed in disappointment "Yes, it's my 7-time I broke it." she took off her motor and stared at now broken device "It went overheat again. The metal for Nitro Motor can only withstand the high temperature for a few minutes until it went explosion and dead."

"Hm…" He stared at the device. It's indeed the metal had wide crack, revealing the engine inside broken "Can't you find something else to replace the metal?"

"I did, but they were the same like this one." Rose shook her head "By the way, what are you doing here?"

"Ah, I finished my current quest and was about to head home until you… came."

And again, she let out a nervous giggle.

"Since you can't do anything with this." Elsword said and took her broken device "Let's head home."

Rose nodded and followed him.

After the catastrophe, Sander is under recovery from the destruction of the Dark El occurring when the God of Demon thanks to the El Search Party. They had to divide into small party and scattered to other villages as Guardians to protect from Uprising of the Demon. The God of Demon had been sealed up once again by Elesis, whose current identification is unknown. A Knight? El Lady? They have yet to understand.

Elsword and Rose were assigned to stay in Sander afterward.

- Home – 7:30 PM -

"Rose! Dinner's ready!"

"I will be down there soon!"

It's Elsword's turn to cook, or precisely, Elsword's job to cook. Rose couldn't focus on making a proper meal for both of them, as her mind wandering in her own technology thought that the food got burnt without her acknowledge. As a result, she almost destroyed the kitchen a few times. Let just say… they forbid her entering the kitchen.

Rose came down from the upper floor and sat on the chair, waiting for Elsword to finish laying the food.

"I see you got rid of the dirt on your body."

Rose already took shower after they got home. He had to wash her dirty clothes from the outcome of her fail experiments. Right now she had a white pajama suit with dark grey panties. Normally, Elsword would react upon seeing her like this, yet he didn't. She had been like this for year with him that he got used to her article of clothes.

"Well then…" Elsword sat down and clasped his hand while whispering "Thank you for the food." And started digging in. Rose did the same with her own food.

As they were eating, Elsword asked "So? How's going with the Nitro Motor?"

"I lower the amount of nitro and reuse the same material for motor's shell. It won't give the same power as the last test but it will last longer." Rose told "I focus on finding material that has high durability and heat resistance." Elsword nodded.

"Speaking of that, I heard Emirate found an abandoned area which used to be the mining area. It was taken by Karis' demon before but since she was driven away, we can retake it and hopefully you can find something useful for your gear." He paused a bit and then continue with sweat-drops "Just in case, I will have to wear full armor when you test something."

Rose knew what he meant and only scratched her cheek in embarrassment.

- The Next Day -

Both Elsword and Rose arrived at the mining area. As he said yesterday, it was abandoned. The equipment of mining were scattered on the ground. They entered the mine with the lamb still functioning well.

"How deep is the mine?"

"Beat me. Emirate only told me this place. He has yet to examine it so I can't tell." Elsword told and kept walking.

As they kept entering, the light of the sun was slowly out of reach and the mine went darker. Rose slowly clung on Elsword's shirt, getting his attention as they slowed down a bit. They then saw multiple ways from the main path. Elsword clicked his tongue in annoyance before he took out the small paper and a pencil before he drew on it.

"What are you doing?"

"I'm tracking the mine's path since we don't have a map of this. It's dangerous to go further." Elsword said and finished the drawing at their place "Anyway, we have to pick the path carefully. It's not safe to go all alone."

Thus they started picking a random path and entering there. The path was roughly unstable, rocks lying on the ground.

"… it's a dead end…" Elsword stated in disappointment as he reached the end of the path. He could tell the path was close due to the collapse that shut the path "Let's head back."

Rose nodded and turned around. Elsword followed her, yet he stopped to find something lying on the ground. He picked it up and saw a strange stone. It's kind of larger than his hand yet it was lighter than it looks. He put it in his bag and proceed to followed her.

Both of them tried many times with many paths yet they only found dead end, plus they found many small craters, possibly the trace of the resource been harvested by demons. Or the paths were closed by the collapse. They reached back to the beginning and started to pick another path only to be postponed when Rose's stomach growled. She hugged her stomach and giggled in embarrassment. Elsword sighed and took out the bread, tearing it in half and gave one of them to Rose, which she accepted.

"After this, we start searching the last path, hopefully we can find something." Elsword spoke "If we can't, we have to leave. Something tell me the mine is out of ordinary."

"Dark El?"

"Probably, it was used to be under demon's grasp, so it's not surprised if something relates to Dark El." Elsword spoke and bit the bread "But I hope I'm wrong. We can't fight them in this mine. It's too weak. One strike and we're buried."

"D-Don't scare me." Rose stuttered and hit his chest, earning a chuckle from him.

"Sorry." He grinned "You're so easy to tease."

Rose pouted and looked away. Elsword chuckled again and took out the bottle to drink half of it till before giving it to Rose.

"Come on, let's go. We don't have much time."

Rose took it and drank it up and returned it. Both returned their last path. However, this one was kind of longer than others. Rose had to grab his shirt due to the darkness inside the mine getting darker.

"Hold on." Elsword halted, startling Rose.

"W-What is it?"

The knight walked close to the cart and found scraps lying on the ground. He mentioned Rose to come closer and said "Some of them still intact. Can you tell which one you are looking for?"

Rose nodded and start inspecting them one by one. She eyed on the quality of the scraps and durability of it to see if they can fit her requirement to craft the frame of her Nitro Motor. The woman then stood up with a disappointment look.

"I can't find it. Sure they still look new, but they can't withstand the high temperature."

"Haiz…. Right. That's all we can find in here."

Rose and Elsword walked back to exit the mine. Elsword looked back to see sadness on her face as she couldn't find anything. He looked at the bag, thinking of the strange stone he found. He was planning to tell her yet he couldn't tell if it's material for her gear. So he went silent.

"….?! Rose, hide!" Elsword whispered a hurry and pushed Rose back in the mine.

"Elsword, what wrong-" / "Shh…"

She peeked outside the mine and saw what he meant.

Demons.

"What are they doing here?" Rose whispered.

"Beat me. I just found out."Elsword replied in a low tone "They are coming this way."

"I got this." Rose took out the flashbang, pulled the triggered and threw it below their legs.

They saw it rolling from the mine but unable to do react before it exploded, temporarily eliminating their vision. Elsword charged in and slashed those got blinded as Rose pulled out muskets and shot them. Those that regained their sight began attacking Elsword. Those rouge demons shouldn't be the problem to both of them. However…

"Elsword!"

Wyvern struck down and grabbed Elsword before it took part, taking Elsword with him. Rose threw High Explosion grenades at the remains demons before she used Nitro Motor to chase after Elsword.

"Get back here!"

"Eheheh… I don't think this wyvern understood what you said…" He sweat-dropped, watching Rose flying closer. He couldn't do anything at this current state. His arms were grabbed tights on his body by wyvern's claws, unable to move. The only thing he could do was waiting.

Wyvern saw Rose getting closer and roared at her as it flapped the wings stronger, stopping her closer. Rose returned by shooting a few bullets at it, yet it dodged. She boosted her Nitro to avoid the strike wyvern attacked. And once again, she was chasing after it and became quite annoyed. First, both she and Elsword had wasted hours to search the material for her with no success and now they were ambushed by demons.

Rose released the safety trigger on her motor and boosted the nitro faster to catch the wyvern. The wyvern saw her flying before it and couldn't react as she shot it on its head.

"Nice Shot- AAHHHH!"

"Hang On!"

Rose boosted her nitro again to catch up with Elsword, ignoring the fact that her motor is getting overheat. She caught his hand and pulled him in her brace as she released all of nitro to get both to the safe place-

*Bang!"

"!?"

Or it's too soon to say that…

Elsword hugged her, this time, to protect her from the falling on the desert. Luckily, they were rolling on the sand and ended up in the small pool among the desert.

"Ha… Ha… Ha… Nice shot."

Rose rapidly breathed with her weary smile "Thanks…"

They both got out of the pool and lent on the boulder to get rest. They could see the Sander village just right before them, meaning the wyvern almost got both back to the village unintentionally. Rose took off her Nitro Motor to find it broken due to overheat, again. Elsword saw it too and let out a chuckle.

"Guess I owe you one." He spoke.

"You owe me nothing, Elsword. You helped me finding the material for motor's frame." Rose replied "Though, we have yet to find it."

"… Not really…" Elsword muttered, which Rose couldn't hear clearly.

"What?"

"Nothing." He grinned "I think we should call it a day. It's getting dark."

"… right. Let's go home."

Elsword got up and lent her a hand which she accepted and went back to home.

- 2 days later -

- Home – 10h30 -

…

…

…

"Ah! I overslept!"

Once again, our gunner shot up from her bed and found out the time reach 10:30 AM. She forgot Elsword was on duty earlier so he couldn't wake her up. She got up and was about to head for shower. Something caught her eyes on her own working desk.

Her Nitro Motor.

She rubbed her eyes to see it again because her motor was different. She approached and picked it up. It was bright new with the white frame. She remembered it was broken. How could it change so fast? She then saw a small note along with it.

I'm sure you would stay up late to fix your Nitro Motor so I left you sleep longer. While you were sleeping, I took your motor and came to the blacksmith to help me change the broken frame with the strange stone I found in the mine two days ago. The owner told me it's the rarest and pure metal ore that surpassed the standard quality of the normal ore. Sorry to say this. I took your blueprint and crafted its frame as well as setting and testing it. The result is perfect. It can withstand high heat from Nitro Boost and is durable against impact.

(though I got myself crashed on some places)

This got Rose giggle.

Anyway, everything is done. You don't have to worry about this anymore. Also, it's a gift for you.

Happy our 3rd wedding anniversary

Love you, Rose.

From Elsword.

She folded the note and put it inside the Nitro Motor as she replied "I love you too, Elsword."
