Dimension Cataclysm: My Copy Can Be Upgraded

In 2026, a global dimensional rift opened, and countless monsters from parallel worlds poured into the earth. Lu Chen returned after rebirth with the apocalyptic memories of ten years in his previous life. In this life, he no longer works alone, but gathers key talents and activates the "dungeon upgrade system" - clearing multiple dungeons such as Cyberpunk, Cthulhu, and Immortal Cultivation, gaining strength, and being able to "upgrade" the dungeons into real territories and establish power. But behind the dimensional catastrophe, there is an "experimental plan" for high-dimensional existence. Lu Chen not only has to fight monsters and human forces, but also uncover the truth about the disaster and determine the ultimate fate of earth civilization.
