I'm not entirely sure what you mean by block number, are you referring to the inode number?

[Lakshmipathi]

block numbers are stored in file's inode. They represent the location where the files contents are stored.
I would suggest downloading e2fsprogs and spending some time "debugfs" command will help you a lot -e2fsprogs has library that allows all activities with FS. If you want access blocks in "unprofessional messy way" you can check my tool giis source codes

thanks!

what's mean by unprefessional messy way?

giis code doesn't use standard libraries to access FS. Whereas almost all other tools use e2fsprogs library.
