The Golden Finger I Made Up Actually Works?

How do you build a golden finger?

Step one: Analyze the world's code and convert it into a universal language.

Step two: Add some strange abilities, like altering reality, twisting causality, and shattering space.

Step three: Add a little lottery or sign-in System.

And throw in some personal attributes as decoration.

Step four: Secretly tweak the mission locations and requirements, and add a few strange settings.

There, your golden finger is complete.

Now let's find some poor sucker to test this System on.

Chen Yuan is a golden finger designer.

His job is to design golden fingers for transmigrators.

But when one unlucky soul activates the System,

he stares at the sign-in location inside a demon's stomach, utterly bewildered.

Unlucky soul: "Please, just do something decent for once!"
