These Systems Are All Mine

The system that had been waiting for eighteen years actually crashed! The entire system collapsed, with only the most basic functions left? But that's fine, the inside and outside of the system have been revealed in front of me! Now I am not working for the system, but I am working for someone else's system and let them work for me! Travel through all the worlds and make every little person the pinnacle of the world! As for me, I just charge a little "insignificant" cost!
