I solved the issue myself.
If you want to point your domain to https://www.example.com when installing instead of letting it pointing to https://www.example.com/wordpress, make sure you extract all the content of wordpress package prior installing and rezipped only those little files (Root files). when installed with either FTP File zilla or Cpanel, the extraction extracts those little files directly to the root folder, usually it’s public html.
I almost vomited tweaking these stuff. My brain exploded, my guts churn and my eyes! they bloated. LOL
GOOD LUCK FOLKS
