What? I Am Actually the Administrator of the Time Travel System

The universe is vast and there are thousands of worlds. In every world, there will be more or less a time traveler with its own system. These time travelers will often embark on the path of legend because of these systems, thus dominating a world. Since there is a system, there must be someone to manage the system! That's right! I am the system administrator of Time Travel! The world is all under my control! For my use!
