Solving Cases with My Schoolbag on My Back [1990S Crime Investigation]

[1] When Jiang Songhe woke up, she had transmigrated. Before transmigrating: She was a nationally renowned forensic profiler, a nationally renowned expert in criminal psychology, and a police academy student with maxed-out combat skills who hadn't graduated yet. Aside from having lost her parents young and spending years alone, Jiang Songhe's life had gone fairly smoothly. After transmigrating: She had a loving pair of parents, an older brother who was a criminal investigator, and a wonderfully harmonious family. Everything was countless times happier than in her previous life! Unfortunately, the original owner of her body was a minor. After transmigrating, she was a middle schooler carrying a schoolbag, with classes from eight in the morning to five in the afternoon! Jiang Songhe: Wait a minute, what kind of start is this? [2] After transmigrating, Jiang Songhe went from a university student on the verge of graduating to a middle schooler doing homework inside the police station. All her colleagues at the station thought she was just a brat. Unable to take it anymore, Jiang Songhe warned them: Pinch my face again and I'll bite you. After that, they'd shower her with snacks and gifts. Jiang Songhe: Don't (munch munch) think you can (munch munch) buy me off (munch munch) just like that... Burp! Later, during a school break, Jiang Songhe had no one to look after her, so she followed her older brother, a criminal investigator, to a crime scene. Drawing on her years of experience, she immediately identified the culprit and carefully analyzed their motive and method. When she finished and prepared to receive a flood of unthinking praise, Jiang Mingye, standing beside her with his jaw hanging open, gently covered her mouth. Only after a long pause did he slowly manage a few words: "You're a kid. Don't talk nonsense." Jiang Songhe: ? [3] Jiang Mingye never could have imagined that, despite all his years as a criminal investigator, his little sister would end up being taken hostage by a criminal. They had just tracked down the criminal's hideout, and everyone had their guns raised, ready to storm the place, when a small figure walked out of an abandoned unfinished building. She held a stick in her right hand and opened with, "Bro, what took you so long? I already took down the criminals' hideout." [Content warning] No incest shipping. 1. This is a romance novel, and there will be a male lead, but she won't date before adulthood. 2. Because of the subject matter, please don't post spoilers in the comments. 3. The heroine isn't the traditionally cute type. If that bothers you, leave now. Readers who expect a perfect protagonist or flawless plot may want to steer clear. 4.

Check out my similar upcoming novel, After a Police Academy Teaching Assistant Transmigrates, She Becomes a Human Toddler [Crime investigation, wish fulfillment, period piece] [1] Zhu Chaoyun transmigrated. Before transmigrating: She was the outstanding graduate her teachers called a once-in-a-century talent at the police academy, a genius criminal investigator who solved many major cases and had maxed-out combat skills, and the strictest teaching assistant the academy's elite class had ever seen. After transmigrating: She became a three-year-old less than one meter tall, clutching a stuffed rabbit. It took Zhu Chaoyun only the blink of an eye to go from the "Great Demon King" her students were afraid to cross to a three-year-old who couldn't lift or carry a thing. Zhu Chaoyun, who had worked so hard to build an image as a strict teacher, rubbed her forehead. "Do you have a bomb? I want to blow up this world." [2] As the teaching assistant for the elite class, Zhu Chaoyun was known for being strict. To keep her four troublesome students in line, with all their tardiness, early departures, fighting, and staying out all night, Zhu Chaoyun would open her eyes and immediately point at them and yell. Irritable, bad-tempered, foul-mouthed, liable to explode at the slightest thing: Those all described her. Her four students didn't dare complain, either. The reason was simple: They weren't strong enough to beat her. But by an unlikely twist of fate, they all transmigrated at the same time. They became tall, strapping new police officers, while Zhu Chaoyun became the police station's three-year-old mascot. At the station, four tall young men crouched down and studied the three-year-old girl in front of them, who was clutching a stuffed rabbit. One of them said, "Why does this little ball of rice cake look so much like our teaching assistant?" Zhu Chaoyun, who often made them run laps as punishment, guiltily turned her eyes away. "...Thanks for asking, but you've got the wrong person. I'm just a kid. I don't know you." [3] (The students' perspective) Fu Qinian and the others never imagined that, after they transmigrated, their teaching assistant would become a three-year-old. Her behavior in front of them went from "pointing at them and yelling" to "acting cute and sweet," then back to "pointing at them and yelling," then "acting cute and sweet" again, and so on in an endless loop. Later, they accidentally stumbled into a gun-running organization. While trying to rescue the hostages, Fu Qinian and the others were badly injured one after another. Only Zhu Chaoyun was tossed aside as a harmless child, without even a rope tied around her hands. Just as everyone thought they were doomed, the deafening rat-a-tat of gunfire erupted. Everyone stared in stunned silence. In the corner, a tiny three-year-old had propped up a Type 53 carbine on each side and opened fire, sweeping the area with a burst of shots. Standing on a wooden crate, Zhu Chaoyun shouted, "Whoever dares hurt my students will have to get through me!" [Content warnings] 1. This is a romance novel with a male lead. She will transmigrate back, but she won't date anyone before then. 2. This is my take on the period setting. To make the plot easier to develop, there is no criminal investigation team; the local police station investigates the cases. 3. The first three chapters cover what happens before transmigration. The story after transmigration begins in Chapter Four, so please keep that in mind. 4. If it's not to your taste, or you want to drop it, just click the X. There's no need to tell me in the comments. Negative reviews will be deleted. 5. Readers with a strong sense of morality who can't accept flawed protagonists should stay away. 6. This is a wish-fulfillment story dressed up as a crime investigation novel. If you want rigorous detective work, this may not be for you. 7. If you have high moral standards for the main cast or demand a perfect plot, I don't recommend this story. The blurb was screenshotted on April 4, 2025. Theme: You only have to exist. There will always be someone in the world who loves you.
