A novel's outright purchase referred to the author selling his novel's copyright to a publishing company or an online publishing platform for a certain amount of royalties. This kind of sale of copyrights was called a " buy out." The purchase price would be affected by many factors, such as the popularity of the novel, sales, reputation, and so on. If the novel was very popular and sold well, then the bookstore or online publishing platform might increase the purchase price. In addition, if the novel was adapted into a movie, television series, or other forms of media work, the purchase price might also increase. Generally speaking, the purchase price of a novel would change as its popularity increased. However, this did not mean that the price would definitely increase. The publishing company or online publishing platform would decide whether to increase the purchase price based on factors such as market demand and the quality of the work. After the purchase, the author would receive a certain amount of royalties, but his work would no longer be used for personal creation. If the work was adapted into other forms of work such as movies, TV series or games, the author would still have to pay a copyright fee.
