I Have a Book of Magic

After transmigrating to a world of magic, Lin Yong unexpectedly came across a strange book. It called itself the Book of the Demon God and tempted him to sign a contract every day. Once the contract was complete, Lin Yong was surprised to discover that the book was just like a video game shop, stocked with all kinds of magical goods, a lucky prize wheel, and a wicked loot box. It even reminded him from time to time: “All you have to do is spend money, and you can get stronger!”
