Store of All Realms: Starting from Aliens on the Space Station

When Lu Chen woke up, he found that he had become a security officer on a space station in the near future. The bad news is that the space station is falling towards the earth, the bottom compartment has lost pressure, and there is an alien creature outside with enough blood to burn through the pressure shell. The good news is that he has awakened the world store system. As long as you complete tasks and earn points, you can exchange them for weapons, technologies, abilities, and even extraordinary powers from different worlds. It's just that this system's understanding of "completion of tasks" seems a little strange. Being chased into the experimental cabin by a monster - the system determined that it was successfully escaped from tracking. Captured into the base by the enemy - the system determines that the infiltration was successfully completed. Accidentally blowing up the battleship while escaping - the system determined that the enemy was successfully prevented from retreating. From the crashed space station to the zombie-infested city; from the martial arts dynasty to the magical world where gods look down on all living beings... Lu Chen continued to complete tasks and brought back to his own world the cover of the Help Me Generation novel. Until one day, he discovered that all the mission worlds were approaching the main world. And every task the system asked him to complete was accelerating the integration of the worlds.
