I fly immediately in front of them. I see that they have the same emblem and masks as the masked man in fact they look exactly the same is this clone magic. 

''You! Come with me and I'll promise you a quick death."I said. But they all started melt in front of me. 

The bastard who attacked the Elf kingdom didn't even come himself. I wonder if this is actually even normal magic or spirit magic. 

The diffrence between spirit and normal magic is usually spirits can grant you power in exchange for something and spirit magic would allow him to not need to come closer to the Elf kingdom. I will not let him escape unharmed.

I am an elf I have more magic cores than other races in this world and I have been blessed with more magic cores than others and the quality of the mana that my cores make is pure white. I wonder if I can utilize all of my cores of the 10 cores that I have left, I am after all 14 000 years old currently.

I'll expand my mana aura above the entire Elf kingdom and beyond the borders of the Elf kingdom to detect the user of clone magic. Only downside in expanding mana aura is the amount of magic that it takes to keep it up and how much mana it uses when I start expanding. It might use as much of my mana as 90% to expand my mana aura enough.

As I start feeling everything from the mountain tree in the middle of the village to my grandson and all the other elves, I sart detecting unknown presence at the top of the mountain tree and it seem that the clone magic user is waiting under the trees for something, maybe a spatial magic user.

I'll capture him instatly. I'll use my light speed to get to him.

I appear behind the masked man. 

I won't let him escape. I'll stab his heart and interrogate him in my light speed movement and reinforce his sense of time and mouth to be fast enough so I can get all the information before the blood in his brain has stopped.

As I go for the stab he dodges it. 

"How!" I'm currently moving at light speed.

"You clearly are under estimating my abilities, after all you are a mere elf." As the masked man finished speaking those words, I can start feeling the most bloodlust I have ever felt in my entire life as he starts making clones.

"I'll explain my magic to you. It's making infinite amount of clones. As long as I have mana I can make them. Only downside is that those clones are weaker than my mainbody about 90%, but I can solve that by reinforcing my self with enough mana." How much mana does he have. To become faster than my light speed without the reinforcement benefit from your magic element.

I just hoped to see my grandson one last time before I get slain.
