Li Weidong travels back to 1964 and becomes a technician. That year, resources are scarce, and people lack food and clothing. Fortunately, he has access to the daily intelligence system. [One-star intelligence: Tonight, on the north bank of Shichahai Lake, crucian carp and common carp are gathering under the ice to seek shelter from the cold.] [Two-star intelligence: In the cellar of the back building of No. 46 Mao'er Hutong, there is a codebook, a radio, and gold bars.] [Three-star intelligence: Aramco Steel Plant has introduced oxygen top-blown converter technology, the details of which are as follows…] With this intelligence, Li Weidong's life in that fiery era becomes increasingly happy and prosperous.

He travels back to the 1960s and becomes He Yushui's twin brother, He Yudong. He starts by graduating from police academy and on his first day of work, he obtains the Super Police God System, which rewards him as long as he catches criminals.

"Ding, congratulations to the host for successfully capturing the criminal. You have gained 130 law enforcement points, 10 jin of grain coupons, and 130 yuan in cash."

"Ding, congratulations to the host for successfully capturing the criminal. You have gained 500 law enforcement points, 10 jin of meat coupons, and 500 yuan in cash."

In order to change He Yuzhu's fate, He Yudong arrested Bang Geng, who had stolen things, and sent him to a juvenile detention center.

"Ding! Congratulations, host, you have successfully apprehended a special criminal..."

Shazhu had a perfect start in life, so why did he end up freezing to death under a bridge? This is completely unnatural, so how can one change his life? This is a Siheyuan fanfiction, told from He Yuzhu's perspective. It's a story of a fresh start, more about family matters than anything else. There's no bitterness or sanctimony; it's simply how a normal person navigates the complexities of a Siheyuan.

Not melodramatic, not violent, more like everyday writing.

Multiple women + sixth brother + not aggrieved + mild-mannered, no large-scale killing plot, please do not disturb if you mind! Zhang Xingguo's soul transmigrates to a fictional world and finds that this is the famous Siheyuan world. Since he's here, he might as well have some fun! He can't leave empty-handed. A small piece of intelligence every day, he plays the sixth brother in the Siheyuan world, mild-mannered, never suffers losses, and always seeks revenge. He starts by splitting off his family and establishing his own household. "At nine o'clock tonight, Yi Zhonghai and Jia Dongxu are going to the pigeon market to buy meat. They left their twenty yuan 15 meters outside the door." "There is a gold ring in the bird's nest on the big willow tree outside the North City God Temple." "The Red Flag Commune is hiding two big fat pigs and plans to find buyers." "Tomorrow at ten o'clock, a transport truck will be surrounded by villagers disguised as bandits on Miyun Avenue. Zhao Fanshi, the director of the political department of the Ministry of Metallurgy, is on board." A small piece of intelligence every day, I've been making a name for myself since the 1950s.
