I Bring the Protagonists Together in the Book

Su Lin was just a miserable writing slave, painstakingly and nervously churning out words. After two days and one sleepless night, he finally finished his sixth novel, another flop in his usual style, with one male and female lead suffering more than the last. What he never expected was that the male leads' resentment would send him transmigrating into a book, with a mission to boot. Well, would you look at that: the six protagonists from his six books had all met and gathered together. Was this really the world of his old novels? If he failed the mission, he couldn't go back?! He had to bring the protagonists together and pair them all off? From then on, Su Lin was determined to match the protagonists up. He worked hard to make money to support them, and fought tooth and nail for power so he could support them. They were his protagonists, and even if he had to cry, he would make sure they ended up together! From then on, Su Lin made money, grew stronger, seized power, and built an army in the world of his novels, all for the sake of the protagonists.
