Shen Qinghe, the daughter of the former criminal minister, became a female tutor at the Royal Academy incognito, and accidentally awakened the "merit and sainthood system". The system showed that if the enemy hostage, who looked harmless but was actually sinister and vicious, could not be prevented from turning black and destroying the world, she would also be wiped out. In order to survive, Shen Qinghe started a crazy "scoring" mode: not only had to help the old lady cross the road, give porridge and medicine, but the biggest task was to "influence" the young man named Pei Jue.
Pei Jue is a hostage of an enemy country, but secretly he is the feared leader of the Demon Cult, who regards human life as nothing. At first, he regarded Shen Qinghe's concern as an ulterior plan and wanted to kill her several times. Until Shen Qinghe blocked the knife to save him, cleared his grievances, and stood firmly in front of him when he was betrayed and separated from his relatives, just for the systematic saying of "merit +1000".
Later, Pei Jue ascended the throne as emperor and pointed his sword at the world. However, he put away his fangs in front of Shen Qinghe and made a humble courtship: "Teacher, I have put down my butcher knife. Maybe you can look at me instead?"
