Transmigrate Through the Worlds of Horror

The protagonist, Lin Chen, transmigrates to a parallel world and thinks he has been reborn. Using his knowledge of the future, he makes billions through stock trading, buying houses, and winning the lottery. Just as he is preparing to travel abroad and relax, the System suddenly activates and transports him to the zombie world of the Korean movie Train to Busan. After surviving the ordeal and returning to his home world, he is recruited by the country's special department, "Firmament." Only then does he discover that characters from all kinds of everyday TV dramas truly exist in this world, and that the System can open portals to horror and apocalyptic worlds across the Myriad Worlds.
