He Yuzhu's brother-in-law, Su Xun, wakes up one day back at the moment when he has just graduated from police academy and is being assigned to a precinct.
In his previous life, He Yushui suffered terribly:
Her father died when she was little, leaving her to depend on He Yuzhu.
After He Yuzhu started working, Qin Huairu took most of his income, leaving her barely enough to eat. When she married, she didn't even get a dowry.
After they married, Su Xun took a post in Jinmen, so they rarely saw each other. Still, she was good at managing a household, and their life was simple and warm.
Given a second life, Su Xun chooses to serve as a neighborhood officer in Nanluoguxiang, so they can meet earlier and he can spoil his wife properly.
In this life, Su Xun obtains a Max-Level Animal Speech System.
In the 1960s, investigating cases meant relying on manpower to search and question people, making them very difficult to solve.
But Su Xun can solve case after case with the help of his animal friends.
He and a sparrow perch on the roof of a courtyard house and witness the entire process of Bang Geng stealing rice and flour from Silly Zhu's home, then send Bang Geng to juvenile detention.
He takes a wild dog into the mountains to track a killer's dump site and arrest the murderer.
Following a tabby cat's directions, he finds a human trafficking den and rescues abducted children.
By listening to an eagle's gossip, he accidentally learns of enemy agents' plot and immediately arrests them.
Lou Xiao'e's chicken warns Su Xun with its crowing, and he catches Xu Damao cheating with Qin Jingru.
The criminals all wonder, “There were no eyewitnesses. How on earth did Su Xun find us?”
Su Xun replies, “What about animal witnesses?”
Cases involving unlawful imprisonment, child trafficking, and murder are all solved with ease.
With his Animal Speech System, Su Xun solves case after case and keeps rising through the ranks...
