Looking for Quick Transmigration, Everyone-Loves-the-Lead, No-CP Stories Where the Lead Only Wants to Complete the Missions

Looking for books similar to *Quick Transmigration: The Host Is Always Secretly Pretending to Be a God (Three Thousand Realms of the Gods)*. The protagonist only cares about completing the mission, even if that means sleeping with the targets. When it's time to leave, she does so without hesitation and never develops feelings for them beyond what's required by the mission. You know the kind I mean.
