Or You’ll Pay For It

Qing You's name was known in the field as well because she was someone around Slaying God and was skilled in administering poison.

How good was she in poisoning others?

For example, Qing You could brush past someone within three meters and quietly poison said person without even lifting a hand. She could kill someone in utter discretion.

This was how good Qing You was. It was also due to her terrifying ability that the fear everyone in the profession had for her was only secondary to Slaying God. That was because Slaying God came in the open for the kill while the person Qing You killed might not even know why they were dead. It was the wonder of poison.
