With All Due Respect, I'm in the Myriad Heavens, Restarting a Small Universe from the Start

After dying, Lin Nan transmigrates into his parallel-world self. From the start, he's transported to a mysterious space, where, as one of the Chosen, he must face the disasters about to strike Blue Star. He enters one wondrous world after another to undergo trials. If he succeeds in changing the plot and turning the tide, he'll receive supernatural rewards from that world. If he fails, the corresponding disaster will descend upon Blue Star. Lin Nan soon realizes: Wait, aren't these so-called world-ending disasters all plots from movies I watched in my previous life? All kinds of American horror, Eastern horror, disaster movies, science fiction, and superhero films. On Blue Star, where knowledge of the supernatural is scarce, all the other Chosen are trembling with fear and treading carefully for lack of information. But Lin Nan already knows the key turning points in every story. He turns the tide time and again, becoming a savior who stops one disaster after another before they can erupt, and making the Dragon Kingdom the only haven on Earth. Sadako? Why are you crawling out? Here to give me points? Iron Man, that new armor of yours looks great. It's mine now. Uncle Jiu, what? You want me to teach you how to take down zombie bosses with ease? With his information advantage, Lin Nan gradually climbs to the top of the world. Leaders from other countries: Look! Lin Nan's showing off again. Why are the dungeons completely effortless for him? Damn it! Why isn't Lin Nan from our country? Quick! Lin Nan has posted a walkthrough. Copy it! He'll carry us to victory. Other Chosen: (˃ ⌑ ˂ഃ) We really can't copy this. He one-shots every boss. How are we supposed to copy that?
