Siheyuan: Silly Zhu's Transmigration Starts with the Sky Falling!

[Hell Difficulty from the Start: The Secret Service Canteen and the Courtyard, Two Instances Open at Once!] He Yuzhu, a junior clerk at the local gazetteer office, was working late when a dump truck struck him on his way home! When he opened his eyes again... He had become Silly Zhu from Love in the Courtyard, but found himself in the canteen of the Secret Service's Forty-Ninth City station on the eve of the Mid-Autumn Festival in 1947! In front of him, old foxes like Station Chief Qiao and Wu Jingzhong watched his every move. Behind him, the scheming residents of the courtyard eyed him hungrily. With a traitor about to bring the organization to ruin, he activated his System's pocket dimension... It could only hold one cubic meter? That was enough! One bullet was enough to leave a traitor bleeding on the spot! One packet of poison was enough to make a collaborator's guts spill out! With “Hextech” cooking skills in his left hand, he won over spies of every rank through their stomachs; With “Sleeve Universe” tricks in his right, he sent traitors and collaborators straight to hell! Station Chief Qiao considered him a lucky charm, while Wu Jingzhong praised him as a talent! Meanwhile, in the courtyard, he quietly gathered evidence of the residents' future crimes. While everyone thought he was just a cook... He Yuzhu had already begun to turn the wheels of history!
