Fantasy Assassin in a modern world

Loki watched as Evan took another shot and this time he shot a target a bit further away. While he was watching Loki was observing every little thing Evan did. He observed Evan's posture, his breathing and even used a spell to sense his heart rate. 

'I see, there are similarities to the skill I use in my archery. I'm guessing the position he's in is for better control over the recoil, it's pretty stable all in all. Still, movement is restricted in this position... I guess I can try using it for a while to get a better feel of my new rifle. Later I can try shooting with the same stance I use in archery. The recoil shouldn't be a problem with how powerful my body is.' 

Loki then started thinking of different ways on how to improve the way he would shoot using the modified Barrett M82. While he was thinking Evan was done with shooting, he then approached Loki with a satisfied expression on his face. 

"This is a good rifle, I don't know who the maker is but every part was made with care and dedication. I could feel the maker's spirit, his very passion as I shoot." Evan gave back the modified Barrett M82 a little bit reluctant. "...So anyway, how about we start. I'll teach you how to do the proper shooting posture, first you-" 

Evan wasn't able to finish what he was going to say as Loki had already gotten into a prone position. Loki's prone position was very proper which surprised Evan. This was the first time he saw a beginner get into the prone position so quickly and was able to align his body properly. 

Loki was now in a state were he was trying to feel the entirety of the area before him. He could feel the caress of the wind and could even sense the subtle changes within it. Once he was in this state Loki used a minor spell [Eagle's eye]. 

The [Eagle's eye] spell was a minor one used by most archers in his old world. It was a spell that allowed the user to see an area of five kilometers with a bird's eye view, with Loki's current mana supply this was one of the few archery-related spells he could use at the moment. 

Once Loki got a good view of the area he picked the target farthest from him, it was placed more than a kilometer away from him, not only was it far but there were many obstructions in between them. Evan noticed where Loki was aiming the rifle at and was at first going to stop him since even with his modified Barrett M82 that shot was difficult and nearly impossible for a beginner to make. Heck even Evan himself would find it hard to get that shot, as he would need to make the bullet go in a thin straight line in between the different obstructions. Still, after seeing how good Loki's form was, Evan wanted to see what Loki could do. 

Loki stabilized his breathing and unlike Evan who even after doing his best was still moving the rifle up and down though only slightly, Loki, on the other hand, made the rifle barely sway from his breathing. Loki could already see the head of the target because of the spell [Eagle's Eye] but he still decided to use the scope of the rifle. 

'Hmm, this is better than I anticipated, using the scope does give me a good view of the target, but using the [Eagle's eye] spell is still better. Well, I guess if there are some cases when I need to preserve my mana this scope would be a great help. Now then, let's test this out with a normal shot.' 

After he was done getting a feel on his weapon and the environment Loki pulled the trigger. The recoil from firing the modified Barrett M82 was surprisingly more powerful than he initially thought, still, it wasn't too bad as he didn't move backward like Evan. Loki then looked at the distance and saw that he had hit the target but was slightly off from where he wanted the bullet to go through. 

'Hmm, even after using the [Eagle's eye] as well as stabilizing my breathing using my mana, alongside using the archery technique [Precision] I wasn't able to hit what I wanted to hit. Heh, I guess even for someone like me using a new weapon still requires a bit of practice. Now how should I do the next shot?...'

While Loki was trying to think on how to improve the archery techniques he knows when using the rifle, Evan had his binoculars and was looking at the hole on the target that was one kilometer and four hundred meters away. 

Not only was Loki able to make such a difficult shot on his first try, but his shot was even more incredible than it seems. Along the way, to the target, the bullet would pass through various obstacles that were between Loki and the target. These obstacles had a very small hole that the bullet could theoretically go through, but shooting through such tiny holes was much easier said than done. Not only did one need to have an amazing rifle, but you would also need the skills to match. 

'Is this guy really a beginner, am I being pranked or something? What am I supposed to teach this guy, he's way better than me!' 

While Evan was getting confused by the situation he was in, Loki had made another shot. The same as the first shot, Loki fired at the target the farthest from him. This time when the bullet hit the target Loki was satisfied, he was able to hit where he wanted the bullet to hit. 

'This weapon is pretty good, just a little bit of adjustments and it already performed the way I want it to. Now I did want to test out if I could apply spells into the bullets, but I guess I'll do that when I'm alone.' Loki glanced at his dumbfounded instructor. 'For now, I better check out the other guns.' 

...

Evan couldn't believe his eyes as he stared at the target through his binoculars. Loki had hit the same spot he shot a while ago, in fact, it was only off by a few millimeters. The bullet almost went through the hole made by the first bullet Loki shot. 

"Hey, Evan, let's test out another gun." 

Hearing Loki's voice Evan put down his binoculars and looked at Loki with a bewildered expression as he nodded his head.
