The Mighty Mage

[Warning: Don't judge on the basis of the first 200 chapters. ] Gu Jin the boss of a top mafia organization was stunned to find that she had suddenly arrived in Magic World. She thought she transmigrated in a novel about Magic, and she became a supporting character who would die protecting the Female lead, and this is all due to her incompetency in magic. Gu Jin laughed 'incompetency?' She can die in every possible way but not due to incompetency. Before transmigration, she was the queen of the mafia world, a strong-willed iron lady. After transmigration, she became a good-for-nothing? She was nothing but a potential mage. She took an oath to become a Heaven Rank Mage. Every colleague of hers despised her until one day they got to know about her potential. Incompetency? She has a special body type which grants her power to have multiple elements while others only had few. Not talented enough? While others were cultivating and having trouble learning alchemy, she cultivated, made formulas of her own, and learned other things too. Is poor? Sorry with her talent in business and alchemy, she had built a business empire of her own and ranks among the top rich individuals! Does she have no supporters? The citizens of Fujio worship her like a god. Her popularity is more than that of the female lead. Has no family? So what! The little boy she adopted is Beast Tamer, the little girl she rescued was a Mystic cultivator. But the drama began when her biological family picked her up. Turns out the Female Lead was the fake daughter and Gu Jin was the real daughter. The Female lead warned her, "Eldest Brother, Second Brother, and Third Sister are too cold, if they ignore you and you feel hurt I will apologize on their behalf, after all, I am their beloved person." Gu Jin didn't have much hope from her biological family, since the female lead was so lovable. She was sure that they wouldn't love her. However... The eldest brother of the family patted Gu Jin's head, "I bought this Divine Level Artifact for fun, you can have it." Gu Jin: "..." The second brother of the family who had a cold nature chuckled, "Who dares to taunt Gu Jin? I will chop off their finger...I mean I will have a civilized talk with them! " Gu Jin:"..." The eldest sister of the family secretly sneaked into Gu Jin's room every day and claimed to have a headache, "Sister Jin~ Let me sleep with you~ I am having a headache." Gu Jin: "..." Was the female lead telling her the truth? Why was everything so different? .............................................. Follow the journey of Gu Jin to become a powerful mage.
