距離近到可以直直打過去
這一支就是那條直線本身，講的是實際的距離。

If a gun is fired point-blank, it is fired from very close to the person or thing it is aimed at.
近距離地（開槍）
核心畫面
A straight line, with nothing on it. You are so close to the white spot on the target that you do not have to aim above it and wait for the bullet to drop. You point at the mark and it is hit. That flat, unadjusted line is the whole word. Move it from a gun to a mouth and you have the other half of the entry: a question or a refusal that goes straight to the person, with no cushion on the way.

可以想成一條筆直的線，路上什麼都沒有。你離靶上的白點近到不必把槍口抬高、不必等子彈下墜。對準就打中。這條「不用修正的直線」就是這個字的全部。把它從槍口移到嘴巴，就得到這個詞的另一半：一句問話或一句拒絕，直直送到對方面前，中間沒有任何緩衝。From the word’s history
Wiktionary derives the word from French point blanc, white point — the white spot aimed at on a target — with an alternative account of firing horizontally into empty space. Either way, the root names the thing you aim straight at, which is why the modern word is about a line that needs no adjustment.
來源記載這個字來自法文 point blanc（白點），也就是靶上那個要瞄的白點；另一說是指水平射入空處。不論哪一說，字根講的都是「直直瞄準的那一點」，所以今天這個字的核心才會是一條不必修正的直線。
Wiktionary entry for point-blank (kaikki:3f6f69a190036ae4:1072838397:11529): from French point blanc (white point), originally the white spot aimed at on a target.

話也直直送過去
把那條直線從槍口移到嘴巴：話中間沒有緩衝，也沒有繞路。

If you say, ask, or refuse something point-blank, you do it in a completely direct way, with nothing softened and no reasons offered.
