Book Villains: Something Is Wrong with the Heroines

Through the book+Multiple heroines Lin Feng accidentally traveled into a novel called "The Strongest Dragon King in the Demon City", but he didn't expect that he would actually become the biggest villain throughout the book. He thought he would live a miserable life of being slapped in the face by the protagonist of Dragon King, being pushed all the way, and finally dying on the street. However, he suddenly got a diary system. The system told him that as long as he concentrates on writing a diary every day, he can get rewards to make himself stronger! More importantly, as long as he completes the plot honestly, he can finally return to his original world, and he can take all the rewards he received back intact! With the guarantee of the system, Lin Feng, who originally felt that his life was gloomy, suddenly had hope of living again. But when he started writing down his diary, he discovered that the original heroines were becoming more and more wrong...? Chu Wushuang: "I don't want to be with that bullshit Dragon King! Even if I want to, I'll be with you!" Chen Yawen: "Lin Feng, please protect me, please? I don't want to be made into a human elixir by that Dragon King..." Nangong Wan'er: "Brother Lin! I don't want to be with that stinky man! I want to be with you!" Lin Feng: "I'm here to be a villain, what are you doing by hanging around me?!"
