Siheyuan: My Mortise-and-Tenon Joints Connect All Worlds

Lin Que, a down-and-out 23-year-old architectural designer, is forced to inherit a three-courtyard house in Yanjing, but is pushed to the brink by the five million yuan in renovation debts left by his grandfather. After activating the Craft of All Things System, he discovers that repairing the dilapidated ancient buildings in the courtyard can earn him resources from across time and space. When he restores a carved window from the Republic of China era to 30 percent, a Luban forging pattern appears in his palm, allowing him to soften metal. While restoring the brick cellar from the Ming dynasty, a mortise-and-tenon wormhole leading to the Northern Song dynasty suddenly appears underground.

On the night a developer hires thugs to splash red paint around and forcibly demolish the house, Lin Que activates the Yongle-era bas-relief of Xuanwu, hidden in the west wing. Phantom images of the Twenty-Eight Mansions descend and suppress everyone there. The next day, as he livestreams the melting of Warring States bronze fragments into carbon-fiber roof beams, a Palace Museum expert rushes into the stream and sends a hundred rockets: "Young man! I'll pay twenty million for that rotten beam in the main hall!" And when a well in the south-facing wing begins leaking gilded gears from the Western Zhou dynasty, he gradually realizes that this courtyard hides a time-space furnace spanning five thousand years of Chinese history...
