Myriad Realms: I Can Make Golden Fingers

After transmigrating to another world, Su Mo doesn't get a golden finger. Instead, he gets a golden finger factory.

From then on, System after System rolls off the production line, and Su Mo sells them to the protagonists of various worlds, turning them into his tools.

In another world, he rises from commoner to noble, progressing from baron to viscount and finally becoming the emperor of an empire, ruling the world.

Or he can build a warm harem for elves, demons, catgirls, princesses, and saintesses. He's got it all.
