Tower of Fictional Worlds

On the planet Blue Star, different dimensions are merged, and dungeon portals start appearing on the planet, and when people lose all hope, suddenly towers start appearing all over the world. People need to clear simulations and climb towers to gain Tower points (TP) to buy skills or to increase stats to fight against dungeon species. Liam is a transmigrator from planet Earth and is surprised that all the simulations are related to movies, anime, web series, novels, etc. Being familiar with the plot, he becomes the strongest in existence and saves the current world from supernatural invasion. Note: This is my first novel, and bear with me if I make some mistakes. This is work I have done from the inspiration of some fanfiction novels.
