I know the modification of talent is very difficult.

This is because the change of the talent is associated with the script.

The more difficult reason is because it is harder to approach than the others.

I have read the guide on talent edit, but it is very unfriendly.

Any talent can be changed by data.txt in the share folder.
But, I want a new talent.

Where are the existing talent scripts? I want to see it and learn.

And many will be inspired if you kindly explain the script's location and editing options for talent, attribute, skill (combat, civil) options.
