The male protagonists of the system can no longer continue to be lonely

There are three thousand small worlds, and each small world has a lucky child. Because the male protagonists are devoted to their careers and do not marry or have children, once the male protagonists are done, the small world will collapse. In order to maintain the normal operation of each time and space, System 01 received an order from the headquarters to find suitable girls to go to different small worlds. Therefore, for the love and peace of the world, the male protagonist must have a sweet love. (?????)? Note: Different small worlds have different male and female protagonists...
