It's an unconventional system story. The protagonist has a weak golden finger. He slowly upgrades, but maybe he won't be very strong in the end.
There are always some "master cooking skills" and "medical masters" and other skills released in the system text as rewards for completing tasks. So where do these skills come from?
The story of Zhou Su, the provider of golden fingers, who strives to upgrade in order to escape from slavery.
I plan to finish the full text first and then update it.
