What file that code actually 'work' for mine?

So after block found, all workers(nodes) now work for new block,

following its algorithm, SHA256, if Bitcoin.

Then what is source file name (or function name even better) that code this algorithm actually working part?

Could you clearify a bit what exactly you are looking for?
Bitcoin is open source and can be found here: https://github.com/bitcoin/bitcoin

So I want to know script's structure, for new block generation process and its work process for satisfy proof of work function is pow.cpp.

Eventually, I want to know how to do actually mine and validate genesis block for new coin.
