After Marrying the Son of the Richest Man, His Ancestral Hall Collapsed

After I married into the Gu family of the richest man, his ancestral hall collapsed. On the wedding day, my husband told me: "As long as this light stays on, no matter what business my Gu family does, they will definitely make a profit." It turns out that the Gu family's wealth, which has lasted for more than ten generations, relies on the ever-burning lamp in the ancestral hall to last for hundreds of years! But my best friend and I married into the Gu family at the same time, and not only did the lights go out, but even the ancestral hall collapsed... This novel and its characters are purely fictitious.
