In the nanite world, Y/n L/n is standing on the highest pillar and looking to be in deep thought and holding his sword with his right hand.

'When I was fighting earlier, I make a lot of mistakes when using sword because there are many opening and my proficiency need a lot of work as well.' I thought

"Omicron, I want to train and as for the enemy, please make it C.Os. As for difficulty, I want you to set it based on my swordplay in my previous world."

"Understood."

Suddenly, the place shifts last the last time I train here but the difference is the enemy is the C.Os that I faced earlier. I gripped my sword and dashed towards the nearest slash the first one and jump back. Then, I began to recall Valmet's way of training Jonah. If the cut is shallow, just cut more often. With that in mind, I run towards second C.Os who noticed his comrades fall and rush towards me. Keeping a calm mind, I dodge sideways and slash while dodging and turns towards it again and slashed from down-right to upper left making a diagonal slash but after the enemy got killed, the third one already jumped on me catching me off guard but I managed to retreat although I almost lost my balance. So, I begin counterattack by dashing while keeping a sense of my surrounding although limited because I'm not used to it.

"Hah!!" I slashed the third one from down to up. Then, I hold my sword in front of me showing my stance using the kendo technique. While I was in that stance, the fourth one began rushing to me along with two of his comrade and I hold my stance to slash him and I jumped over them, disorienting my enemy, and dashed towards one of his comrades who was near him killing him instantly. Wasting no time, I dashed again to the middle one who led his comrade earlier stabbing it at its stomach and punching its face hurting my knuckle but adrenaline kept me focused. After my punch was delivered, it became disoriented and I hold the sword back and slash the C.Os cutting it from its stomach to the right. Then, after killing the one in front of me, I turned my sights towards one final C.Os but the enemy changed its attribute to shielder who had bulker arms but I know better because I played the game and their speed is lower due to weight and I run towards it using an intent to fake my intentions, it began to take a shield with its arms losing its sight as a result, then, I jumped over them and slashed them from the back but the wound is shallow and its roars as a result. I do not want to lost opportunity slashed again and again without care and finally kill it. Dropping myself to the ground and panting because I'm not used to this fight.

*Inhales**Exhales*

"I never knew a fight would be this exhausting." I said while panting."Omicron, please rate my fight."

"Understood......Rating the fight.......Complete.....Showing the results."

"B+, I guess I have to improve myself but before that, how much time passed?"

"It is at only 1:00 am."

"Alright, Omicron. One more time" I said intent to do training again.

"Understood, Y/n"

So, I use that time to train till it was 4:00 am and go back to sleep.

Timeskip by Y/n is working but keeps getting interrupted by other Counters.

3rd Pov

The early morning comes to awaken Y/n L/n from slumber and looks at the clock which shows 6:30 am." Ugh, I wake up early." He said and closes his eye, opening them again and sitting up on the bed. He then stands up and takes a towel to shower.

After showering, he dresses plainly and currently making breakfast.

Y/n Pov

"Hmm, looks likes I'm adapting to my life here," I said to myself while cooking an egg for a sandwich.

'Hey, Omicron.'

"Yes?"

'is there any entertainment like Tom and Jerry in this world?'

"Searching....I'm afraid not but if you're interested, there is a group called HRT Berry."

'Yeah, no, I ain't interested in stuff like idol'

"I remembered I only play this game until episode 3 and some side story in CounterSide." I said "Tch, there's not enough information especially with that guy," I said referring to the CEO of Coffin Company."

CEO of Coffin Company.

It can be said that this guy is more than meets the eye fighting against an enemy from another world whose name is currently not known.

*Sigh softly*" No matter, I'll handle that I can handle and leave the rest to him," I said while finishing making breakfast.

With that, I put my breakfast on the plate sit on the couch, and open the TV to watch the news. After finishing his breakfast and washing his dish, he sits and the couch looks around his surrounding, and realize one thing, there is not much furniture. He checks his phone and looks at the day today is Friday.

"Hmm, tomorrow I'm free and there are no shifts on Saturday and Sunday," I said musing whether I will buy furniture or not.

'Omicron, do the place I got to buy grocery that day sells furniture?'

"Searching....Yes, the place you speak of doing sells furniture."

"Hmm, I guess I'll buy shelves to store books and diaries. What time is it?" I said and look at the clock which shows 8:30 am.

"Guess I'll go out and take fresh air." With that intent in mind, I dress up and open and was about to lock the door but I heard a voice calling me and I turn around who called me making me speechless and little agape.

"Hey, Y/n. Long time no see."

Maria Antonov

'Holy moly!!! It's Maria Antonov, wait, now that I think about it the previous owner of this body is her neighbor right? I forgot about her and just focus on my job and experimenting.'"it's good to see you again, Miss." I responded.

"Just call me Maria. I thought you will just stay inside considering you had day off right now." She said with a smirk.

"Need a fresh air and walk to calm my mind considering Corruption Disaster is happening too often."

"Yeah, considering how often it is, it's understandable but it's good to see you getting out of sanctuary, unlike certain someone."

I chuckled hearing who she refers to.

"Well, don't let me keep you here considering where you're going." I pointed to her clothes.

"Haha, understandable, see you later." She said and waved at me before going somewhere else.

"User."

'Yes?'

"Yoo Mina has transferred to another company."

'I see, keep a lookout when she transfers Coffin Company.'

"Understood."

Then, I get out of the apartment after locking the door and just walk towards the park to rest because I want to catch an idea of what to do.

Timeskip by Y/n head patting Hilde but Hilde is intent to kill him but fails.

Soon, I arrived at the park seeing some kids around, then, I look for a bench and sit on them.

*Inhales* *Exhales*" This is refreshing and the air is cleaner than my old world." I said while sitting on the bench which is shaded by a fairly large tree giving it enough shade for the sitters on the bench.

I look at the kids playing around but I recognized three-person from the game, Han Sorim, Cho Hojin, and Yang Harim but I didn't go towards them because I don't want to be labeled as lolicon and just close my eyes feeling the wind blows into my face. After that, I decided to ask Omicron.

'Say Omicron, can I use the Omega-1 machine?'

"Yes. It has already been unlocked the moments you use your power."

'I see. Can I see it?'

"Yes. Showing user the blueprint of Omega-1 nanites."

"Blaster Caster"

"Funchucks"

"Bad Axes"

"Block party"

"Sky Slyder"

'Thanks, but can I use something like a powered-up version or something? Like when Rex combined with Upgrade.'

"It is possible. Any suggestion you want?"

'B.F.S combined with elemental or Space-Time or Gravity.'

"I shall research and make a blueprint about it."

'Wait, you can multitask?'

"Yes. I can run a million programs and still be able to modify your body if you need to."

'Okay, That's awesome!!!'

"You're welcome."

With an assuring smile, I opened my eyes again and the wind blows showing the day is windy and I decided to take a walk beside the park.

3rd Pov

Y/n go to different places such as bridge, café, ice cream vendor and bookstores buying a book about Mathematics. Then, he goes to the motorcycle shops for window shopping, of course. Next, he uses his new phone to copy the new system of the current phone by using Omicron to read the programming when looking at the phone outside the shop. Afterward, he goes to a stall where he buys a meat bun and returns home and sleeps.
