Creator Game: After the Character Awakens

The character I wrote became my mortal enemy. Lin Muzhi, the author of "The Street", was dragged into the world he wrote by a bronze pen. Mission: Kill the protagonist created by your own hands. Reward: Pay off millions in debt and regain your life. Punishment: tenfold debt and ALS. He thought it was a simple "NPC elimination battle" until he discovered that the protagonist had a time traveler from the earth hidden in his body and was bound to the Tiandao system. What's even more terrifying is that there is not just one copy of the bronze pen, but all the novels he wrote. Fantasy, supernatural, urban... There are even works about eunuchs. No one knows what the protagonist's future will be, and naturally he will be the same. How can established characters create strange sparks? "You create them, you have the highest authority." When the characters in the novel begin to rebel against fate, when fictional horrors invade reality - who is the one who is written?
