Western Fantasy I Unlocked the Module in My Book

Mc fan + author's book + plot prophet + upgrade flow + module unlocking Shen Yan failed to write "The Age of Gray Crown". There are 2.8 Million words, the foreshadowing has not been filled in, only three of the protagonists have died, and the ending has been lying on the hard drive for three months. Late one night, there was an extra sentence in his document: "Since you know everyone's ending, then write it yourself." When he opened his eyes again, Shen Yan had come to the western fantasy world he wrote. Six hours later, Rye Village will be slaughtered by demon corpses; three years later, the black moon will come and the gods will go to war; and on that unfinished last page, the entire world will be swallowed up by a blank. He had all of Steve's abilities in survival mode and saw a mission he couldn't refuse. [World Node: 0/12] [Complete the node and unlock a module randomly. [Complete all nodes to return to reality. From the first workbench, to equivalent exchange, general machinery, dragon research, to endless greed. Shen Yan originally thought that as long as he developed according to the original work and used the MC mechanism to solve the difficulties, he would be able to return home smoothly. But the first village that should have been destroyed survived. A girl he had never written about appeared in the ruins. And the final villain, who was born from scrapped manuscripts, discarded designs, and dead characters, also knew that he was the author of this world. It doesn't want to prevent Shen Yan from passing the level. It just wants to snatch the door to reality when the last node is completed.
