Eating The Forbidden Fruit

The tree wall suddenly fade off instantly, like there were a soggy piece of noodles. I didn't know what happened when I saw those tree dying, but when I looked at the ground where the trees are planted, the color of the ground was black and it looks like a deep cold hole. but I was mistaken, it was mud, but In different consistency and build. Then after the tree died from the black mud, Bouro put up his hand on the air and the black mud fly into the sky, like he was manipulating it. Quin looked so confused when it happened and honestly, I like that look of his, but Quin immediately activate another spell called; " Tree Magic: Forbidden Fruit!". A small golden tree appeared infront of him and he grabbed its red colored fruit hanging on the side on the golden tree. At first, I was confused and all I can think of was the forbidden fruit from the story of Adan and Eve, but I was wrong. Quin ate the fruit and his Mana suddenly outraged and reaching new heights, he even got closer to Violet's Outstanding Magic rating; Quin's Magic rating went from 8,000 to 40,000, Which is really impressive. But I'm sure that there are circumstances on gaining those tremendous amounts or Mana.
