Quick Transmigration: Host, You’re Far Too Calm

[Woman disguising herself as a man + quick transmigration + System + no romance] Zhang Siyu was merely a nominal assassin for an assassins' organization. They'd said her abilities impressed them and they wanted her to join, but she didn't want such dangerous work, so they asked her to lend her name to the organization instead, in exchange for a salary. Zhang Siyu figured, why turn down free money? So she agreed. Who could have guessed she would be made the scapegoat for her teammates and killed by them? Then the quick transmigration System bound her to it, and she began traveling to different worlds to complete missions.

[World One: The Republic of China...] In the chaotic era of the Republic of China, Zhang Siyu's mission is to help her original body's guardian get revenge. In the end, it turns out to be him...

[World Two: Being an Ancient Emperor Isn't Easy] Zhang Siyu becomes a fake emperor in ancient times. She has to deal with the ambitious regent and prime minister, fend off a loyal general who's determined to rescue her, and keep her secret identity hidden...
