Quick Travel: the Male Protagonist's Intersection Tool Man

The plot goes through very quickly, and there is no need to expand on the first five chapters. After all, five chapters are a world, and there is no need for foreshadowing in the first three chapters. After all, the foreshadowing only takes three sentences! It only takes three minutes. If you can't stand it for three minutes, it's definitely my fault. Please give me three minutes! You can't buy, you can't lose, you can't be fooled, it only takes three minutes! (Advertising slogan of the epileptic author) The story goes like this. Our male protagonist, Cheng An, first thought he was an ordinary person, but suddenly discovered that his world was actually a novel, and he was an NPC. The system said, young man, you have a problem, your data is not right, you let the two male protagonists fight for you! Cheng An thought, it's over, it's going to be wiped out. Unexpectedly, the system is very reasonable, saying, "Don't worry, young man, we haven't found any problems with you. In this way, I have 5 worlds with similar proportions of characters. You can choose any one to finish the plot and retire!" Cheng An: Woohoo, system, you are such a good person! Unexpectedly, the world that was originally running normally fell apart after Cheng An arrived. And Cheng An gradually discovered that perhaps, this matter was not that simple. The first world: campus novel (not the original world of the first chapter) The Second World: Ancient Machiavellian Writings The Third World: Cultivation of Immortality The fourth world: ABO text The fifth world: Game world (various ghost stories) Intention: Goodwill is king!
