The Courtyard Is Full of Beasts, and You Call This Guy Honest?

[Period setting + feel-good power fantasy + master chef + stealing the love interest + multiple heroines + System + enemy agents] I transmigrate to the 1960s, and right from the start the head chef, Silly Zhu, humiliates me in public and orders me to scrub the toilets? The whole courtyard is full of scheming beasts watching me like hawks. The hypocritical First Master, the two-faced Qin Huairu, and the vicious Jia Zhangshi all want to devour me alive! Fortunately, my God-Tier Intelligence System activates! Silly Zhu tries to bully me out of jealousy? I use a dish fit for a state banquet, “boiled cabbage,” to snatch his promotion, leaving him utterly humiliated! Xu Damao mocks me for scavenging junk? I turn around and resell a rosewood pen holder, earning three hundred yuan as my first big payday and making him lose it on the spot! At a courtyard meeting, they accuse me of immoral behavior? Armed with ironclad proof, I expose Xu Damao's disgraceful antics: he harassed a woman and wet his pants. Then I take Silly Zhu down with a grappling move, establishing my authority in front of everyone! With the System's intelligence, I amaze the leaders with my unmatched cooking skills and rake in money from comic-book scripts. I steal Xu Damao's chance to marry the beautiful, wealthy Lou Xiaoe, then help my capitalist father-in-law's entire family get their political labels removed! I thought this was just a tale of working hard to get ahead in a courtyard full of scoundrels. But one night, I catch the deaf old lady in the act: she's a deeply embedded enemy agent. The astonishing secret she's hidden in the courtyard is enough to doom everyone...
