The Last Alchemist

In a world full of magic there are 4 types of magic which are "Light Magic, Dark magic, Elemental Magic, and the Alchemist" these 4 types of magic are the original magic from 2,000 years ago. The strongest Magic among the 4 is the "Alchemist" the alchemist has a special ability that can use all types of magic at any time, so Alchemists are called monsters. In the past there was an organization of the 3 types of magic planned to kill all the alchemists users. Even though the alchemists users stand their ground. But in the end they were all destroyed. There are some remaining Alchemists in this world until now. but some of them had already died... One night, there is a family who are eating peacefully together, but suddenly they hear a loud noise outside their house. The Father of the family rushed outside and saw a kid in their doormat. The Kid cried and cried. The Father that was worried that the kid might die if he left him outside took him in and adopted him.. Five years have passed. The kid's name was Zamier Wuyon, and the people who adopted him are Harley Kim which is the Father and Sheryl Chi which is the Mother. Harley trained Zamier in sword fighting. but zamier suddenly asked his father, "Dad! can you teach me magic?" Harley replied laughingly "Haha. sure! i will teach you!" So the Harley took a stand and shot fire out of his hands. Then Harley Explained to Zamier. "There are 3 types of magic which are Light, Dark, and elemental magic." The father explains to his son that he is an elemental magic user. After harley explained about magic they continued the training. and when zamier was still little he was smart, and read books even at a small age. and has a vast amount of Mana.. After many hours. Zamier is still fighting his father. Harley exclaimed that "Zamier has a lot of stamina and strength but still can't win against his me." Harley was getting excited but in zamier's mind he is at his limit, in a blink of an eye, zamier attacked his father with much speed and hit his father five times in one swing!. Then Harley was shocked and did not expect this. After the attack zamier collapsed. Harley rushed and helped zamier and carried him, and thought "How did he attack me five times with one swing?".. After the event Harley said to his Wife Sheryl. "Love" "Yes my love?" "I want to tell you something, it is about zamier" "Oh?" "I was training with zamier, I saw that he has alot of potential, but he was not using it right, but in a blink of an eye he swong his sword five times in one swing and after that he collapsed" "What??!, I never thought he has alot of potential!" After that Harley and Sheryl got ready for bed... *In Zamier's Mind* "Where am I?" *unknown being* "You are the last....... you need to save your......." "What?? what do you mean i am the last?? and who do i need to save???" *Unknown being* "Help us...... from......" "From what?!!" And then the being vanished...
