In the spring of 1918, Bai Shouli, a well-known architect from Peking, accepted the commission to renovate the haunted house of Baylor in the former Qing Dynasty. However, he unearthed seven corpses arranged in the shape of a big dipper in the rammed soil. The quenched locust flowers are falling from the ancient locust trees, and the soul of a crying baby in the east ear room imprints AB blood type palm prints on the wall. The faded annotation book of "Construction Procedure" in the dark space on the ridge of the main house actually marks the coordinates of the Japanese Army's Bacteriology Laboratory in 1937. On the night when the mortise and tenon chain of the Weeping Flower Gate was split open by lightning, revealing the magnetic levitation star chart, the Bai family was shocked to realize that this nine-entry courtyard was actually an armillary sphere used to measure earth veins during the Mongolian and Yuan Dynasties.
After seventy years of ups and downs, the courtyard has turned into a whirlpool that swallows fate: the "Eight Scenes of Yanjing" hanging in the Japanese colonel's study hides the distribution of uranium mines, the old luthier played Morse code on charred beams during the Cultural Revolution, and the swaddling clothes in the pottery urn fought over by Taiwanese businessmen were wrapped in a Warring States jade cong with radiation. During the AR restoration project in the new century, Bai Yanqiu, the fourth generation descendant of the Bai family, discovered that ghost craftsmen from his grandfather's era were wandering in the holographic projection, and the murals that appeared when the smart home went out of control pointed to the Beidou Seven Wells under the central axis - where the meteorite compass that changes the earth's magnetic field sleeps.
Three generations of guardians competed with descendants of warlords, Japanese scholars, and mysterious tombkeepers. The puzzle of the nine-layered building has changed with the times: from the wooden tenon mechanism to the quantum key, from the caisson star map to the dark matter reactor. When the final leyline chain was revealed in the hadron collision, they understood the ultimate warning left by the founder of construction: Beijing was originally a living altar that locked down ancient civilization, and Chi Kiss, squatting on the eaves of the courtyard, was the pupil that activated the world-destroying mechanism.
