Hundreds of years ago, the Sarlang warrior VarChang used the Blade of VarChang to kill the Watermelon Demon King, but it was not completely destroyed. The soul of the melon king resided in the Blade of VarChang. Over thousands of years, the watermelon strips tried various methods to try to revive the melon king. Finally, they discovered that the continent of Menventoland was full of magic. The watermelon strips used the magic to reforge the body of the Watermelon Demon King, and the revived king is constantly absorbing the magic of the Menventoland continent.
