Siheyuan: I'm Yan Jiekang, and I Just Want to Get into the Ministry!

Chen Yu transmigrates to the 1960s and becomes Yan Jiekuang, the Third Master of Love in the Courtyard's son.

Faced with a courtyard full of "beasts in the guise of family": the parasitic white lotus Qin Huairu, the hypocritical elder Yi Zhonghai, the lovesick fool Silly Zhu, the childless Xu Damao...

Chen Yu declares, "I'm no saint. I'll get even with anyone who wrongs me, and I won't take a loss!"

Luckily, the God-Tier Sign-In System activates!

From the start, he signs in and earns master-level fitter skills. With one move, "switching the beams and pillars," he makes Qin Huairu cry thief and suffer public humiliation!

He signs in at the steel mill and gets a permanent bicycle, making everyone in the courtyard green with envy!

He signs in at the subdistrict office and earns master-level forgery skills. One fake ledger ruins hypocrite Yi Zhonghai's reputation in his final years and sends him packing back to the countryside!

He signs in at the library and earns intermediate photography skills. He captures Xu Damao's dirty secrets on camera and gets him sent to clean toilets!

He signs in at the national defense museum and earns a universal machine tool!

By the time Chen Yu becomes the nation's chief engineer and marries the factory beauty Yu Haitang...

The other beasts are still fighting like dogs over a bite to eat, while Qin Huairu trembles in terror on the latrine-cleaning crew!
