System: Zhang Moumou is a Japanese spy who will deliver intelligence tonight near the Xiaoheng Bridge pier on the north bank of the Tonghui River. Yan Jiefang will rush to the Public Security Bureau to report him that very night. ... System: At 3 PM this afternoon, Li Huaide's car broke down at the intersection of Dongzhimen and Mianhua Hutong.

At the end of 1948, Chen You traveled to a fusion period drama.

Fortunately, he awakened the sign-in system and obtained the longevity skill.

Female protagonists such as Lou Xiao'e, Qin Huairu, Chen Xueru and others came one after another.

Everyone in the courtyard was envious and jealous, but there was nothing they could do.

Microsystems, systems basically do not appear, and will develop overseas in the medium term.

Gao Zhendong transmigrates into the world of Siheyuan (The Courtyard). As a newcomer to the quadrangle compound, he boasts an impeccable background: an exemplar of revolutionary pedigree, physically robust, strikingly handsome, and battle-hardened from military service where he earned repeated merits. With advanced university education, technical expertise, ample funds, and a system at his disposal, he possesses both the wisdom of his past life and the system's guaranteed resources—occasionally enhanced by futuristic insights from lucky draws.

Rejecting trivial pursuits and petty squabbles over trifles, he aspires to contribute meaningfully in this zealous and vibrant era. At the very least, he wishes to declare in his twilight years: "These two lifetimes have been worthwhile."

A modern-day agritourism owner is transported to the 1950s, hoping to make a modest fortune. He never expected to find himself in a courtyard filled with birds, and discovering he's actually He Yushui's cousin. Watch as the three siblings struggle to survive in this new era…

Gao Hua is reborn into a courtyard house world and works as a purchasing agent in a steel rolling mill. He unexpectedly unlocks an infinite farm system.

Can you get rich by farming?

Gao Hua's DNA has been activated.

He traveled back to the courtyard house at No. 95 Nanluoguxiang in 1951 and became He Yushan, Sha Zhu's elder brother who had returned from the army.

He initially served in the Military Control Commission in Jiaodaokou Street and Qianmen Street area, and as Deputy Minister of Public Security.

Bind to the daily intelligence system.

[Today's Intelligence: He Daqing, who lives in the courtyard at No. 95 Nanluoguxiang, is planning to flee tonight with the widow Bai Dongmei due to fabricated documents!]

[Today's Intelligence: The deaf old woman in the courtyard at No. 95 Nanluoguxiang is a remnant of the puppet Manchukuo regime and possesses a map of the city's defenses!]

[Today's Intelligence: Jia Dongxu, a fitter in the first workshop of the Red Star Steel Rolling Mill, has been suffering from chronic hunger, becoming distracted and being sucked into machine tools!]

[Today's Intelligence: The Lou family, fearing a reckoning from above, plans to pack up and flee to Hong Kong tonight!]

[Today's Intelligence: The proprietress of Xueru Silk Shop on Qianmen Street has taken a liking to you and is planning to get you drunk and make things a done deal!]

…

Relying on daily intelligence, He Yushan thrived in the 1950s.

From deputy minister to minister of the district public security department during the Military Control Commission period.

After the military control commission ended, he was promoted from director of the district police station to director of the Sijiucheng Public Security Bureau.

With the full implementation of public-private partnership, he relied on the transformation of the Red Star Steel Rolling Mill to enter the Ministry of Metallurgy!

In the 1980s, when the tide of reform came, he decided to retreat while it lasted, accumulated billions of dollars, and enjoyed a carefree life!

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.

Reborn in a siheyuan courtyard with a pocket dimension at my fingertips, I embark on a life of leisurely urban homesteading—raising fish, growing vegetables, cultivating ginseng; selling produce, trading fish, collecting antiques... All while quietly observing the ever-shifting dramas of courtyard life...

Reborn?

This... my father is He Daqing!

He's only 10 years old; his silly little sister hasn't even been born yet?

My mother had a difficult childbirth?

No problem, let's save Mom first and let her continue to deal with that unreliable Dad!

He Daqing: You brat, who taught you your cooking skills?

He Yuzhu: "You'll get it just by watching. Your son is a genius!"

He Daqing: "Xiao Bai is really good!"

He Yuzhu: "He Daqing, your wife is calling you home for dinner!"

Yi Zhonghai: "Why isn't He Daqing running away anymore?"

He Yuzhu: "Hey guys, let's go and kill Yi Buqun's little Yi!"

Jia Dongxu: "Why aren't you playing with me anymore?"

He Yuzhu: "You short-lived wretch, go play with yourself!"

Qin Huairu: "Zhuzi, Sister Qin's family is having a hard time!"

He Yuzhu: "Hmm, it could be even more bitter!"

He Yushui: "Brother, Sister Qin is a good person!"

He Yuzhu: "Mother, how about we give my little sister away? You and Dad can have another one!"

Shi Yi has traveled through time. The good news: he didn’t end up in the body of his namesake, the legendary "Double Pupils" figure, nor is he in a perilous fantasy world. The bad news: it’s the early founding era of the People’s Republic, an era of scarcity where food and clothing are hard to come by, and he now has a little sister to provide for. Luckily, his transmigration benefit has arrived—a grand-sounding "system." But aside from the "Newbie Gift Pack," the system's usefulness seems...
