How do you write that?

I like to write stories (especially action and fantasy) so I try to help you. (But I’ve been doing this so recently I can’t give you incredible good advice). So first, of course, it’s important where they fight. So they’re fighting in a bar, throwing beer fights and running over the tables? Or are they fighting in a public place where people try to pull them apart? Can the attack become a martial art and defend itself with well placed punches and tits? Does the attacker have a knife? Is it in the fight for life and death or does the attacker just want to take him off? Of course, you have to think about such things. I’ll write a fight scene from my own story. That sounds strange, of course, because you don’t know the history but don’t care.

Kai ran the narrow alley along his hand tightly around the precious stone on his chain. Behind him he heard the steps of his persecutor, who repeatedly entered the puddles that spread over the whole alley. As fast as he could run Kai around a right curve only to find out that he had landed in a dead end. He slowly turned around and saw his persecutor standing at the beginning of the dead end and looking at him with shame through his mask’s eye slits. “What do you want?” Kai asked though he knew exactly what the masked man wanted from him. He answered not, but only showed his neck. Kai nodded and went slowly toward him as if he wanted to surrender and give him the gem. The masked person looked suspiciously against him and barely carved on the muscles. Kai didn’t wait for the stranger to attack him. As soon as he was close enough, he suddenly stormed, rammed his fist into the stomach and jumped past him. But the masker was fast. While Kai had hit him, he had turned. He immediately grabbed Kai at the shirt collar and threw him back into the dead end. Kai fell against some rubbish buckets and needed some time to rejoice. The stranger left them to him. He wasn’t in a hurry. As soon as Kai stood again, he took a fighting position. The stranger nodded shortly then he ran to Kai. Kai looked like something flashed and licked instinctively. The masker had a knife! Damn it! And somehow the guy came to know him. Kai could hardly grasp a clear thought, already the masked attacked again. This time, Kai’s chest was targeted, but Kai was able to jump to the side in time and caught the stranger with a high kick at his head. The mask flew to the side and Kai and the boy who appeared under her stared at a moment. Jason? What the…” while he was talking, Jason jumped in and rammed the knife into his stomach. Kai yelled up and blew backwards until he hit the garbage cans. He stared at Jason. “I’m sorry Kai. Really. But I have to get Jaru the stone and kill you, otherwise I can get myself to the collar” Jason looked at him cold. “Don’t worry I’ll stop it quickly” he went to Kai to the gorging leaning on the garbage cans to give him the rest. When he stood before him, he leaned against him and smiled. “You see. in a certain way you were too good” he just wanted to stab once again as Kai suddenly pulled up one of the garbage lids and hit him with the last force in the neck. Jason collapsed and fell into one of the countless puddies. Kai looked at him briefly, then he shook his head and humped out of the alley. He had to find help quickly, because he could hardly keep on his legs. Behind him the sun turned red, as did the puddles through which he ran.

I hope very much I could help you:) a lot of success with your story!
