Fantasy Assassin in a modern world

The moment the young man changed his priorities his countenance changed. Loki felt that the pressure the young man was exuding became heavier. At this point, Loki could already guess what the young man was thinking at the moment. 

\'So he decided to get serious now, and deal with me first.\'

Loki knew that at this moment he needed to go all out. He really didn\'t want to kill this young man as it goes against his set of rules, but if he doesn\'t fight properly, it was possible that he would kill him or worst the Twin Stars. 

Loki circulated his mana and used Enhancement on his entire body. Loki got into a fighting stance as he was ready to fight. On the other hand, the young man looked at Loki with a little confusion in his eyes. He knew that Loki was a tricky opponent to handle but for some reason, he could not feel any killing intent from him. In fact, the young man could not sense anything from Loki, it was as if he didn\'t exist. If not for the fact that Loki had attacked him and he was actually hurt a bit, the young man would\'ve thought Loki was just a hallucination. 

Still, since Loki was in the way of his mission and he was real, then he needed to be eliminated. The young man dashed towards Loki, he was like a bullet as he approached. Loki shifted his position and waited for the young man to strike. 

Once the young man was in front of Loki he did a forward kick. The kick was so fast and sharp it created a shockwave, yet Loki was able to evade it by stepping backward avoiding it by an inch, he then used that moment to counterattack. Loki struck the young man\'s chest with his own kick, but the moment he did so it wasn\'t the young man who got hurt but Loki. 

The young man then attacked Loki by swinging the foot that was already above his head downward. Loki evaded the attack by sidestepping then he once again struck the young man on the chest, but this time he used his needles for the attack. Yet even after using the needles, they could not penetrate through the young man\'s muscles. 

The two then exchanged a flurry of strikes, Loki being able to dodge all of the young man\'s strikes while counterattacking. Loki had hit different parts of the young man\'s body who had now many needles sticking out of him. Yet despite all those attacks he had made Loki was unable to damage the young man\'s body. 

They had been going at it for a few minutes now and the young man was getting impatient as he was showing more and more openings. Of course, Loki abused these openings to attack the young man. 

The young man was not just getting impatient now but was also getting irritated. He was no longer holding back and was attacking at full power with the greatest speed yet he could not hit Loki, on the other hand, Loki was able to hit him but all of his strikes were nothing more than a little tickle to the young man. 

\'If I could get one hit, this will all be over.\'

While the young man was getting even more agitated, Loki was focusing even more. It was true that his opponent was faster and stronger than any person he has seen in this new world, but that was it. The young man was too overconfident in his superior body and relied solely on his overpowering strength and speed to win. The young man had no technique and was just swinging wildly. In Loki\'s eyes, the young man was like a little kid that was swinging a powerful sword. 

Still, Loki knew that just one hit from this young man could spell his doom. In fact, despite his calm facade, Loki was feeling immense pressure. He was able to dodge all of the young man\'s attacks due to his fighting experience, as he could easily predict were those large swings were going to hit. In fact, since the beginning with Loki\'s current strength, he was unable to follow the young man\'s strikes with his eyes. The only thing Loki could see was the initial movement, yet with his battle instincts and his experience that was enough to dodge those powerful attacks. 

...

The young man was about to swing his right arm, but for some reason, he could no longer feel his right arm. The young man looked at his right arm and saw it was still attached to his body but was limp and unresponsive. He then glared at Loki and as if growling, finally spoke. 

"I don\'t know who you are, and since you were not someone spoken in the mission briefing I was going to let you leave but now you can forget about that. If you just left and minded your own business I wasn\'t going to chase you, but now you have forfeited your life. Do not blame me for what\'s to come next." 

The moment the young man spoke those words Loki noticed some visible changes in the young man\'s physique as it looked like the young man\'s body was getting slightly bigger. Then there were some tattoo-like things starting to appear and glow on the young man\'s body. Yet what surprised Loki the most was the faint hint of mana now oozing out of the young man\'s body. 

\'Are those runes in his body?\' 

The moment Loki got distracted by that realization, the young man had disappeared from his sight. Loki unconsciously dodged to the side, the moment he did so he felt something pass by him. 

"Oh, even with my full speed you were able to dodge, but it seems that it\'s not as perfect as before." 

When Loki heard what the young man said he looked at his right arm. The flesh on his shoulder looked like it was torn off. The pain Loki felt at that moment was intense, but he did not scream and instead tried moving his arm.

\'It hurts to move it but it was still functional.\' 

Seeing Loki\'s almost nonchalant expression, the young man frowned.

"I will give you one last chance, either leave or die." 

Loki looked at the young man then at his arm and sighed. He knew that he would no longer be able to keep up in his current state, and would eventually lose. 

\'I haven\'t tested this out yet, but I guess it\'s now or never.\' 

The young man who was waiting for Loki\'s reply was stunned by the sudden pressure he felt from Loki.
