It turns out that this mysterious building wasn't built by the Ge family. The ancestors of the Ge discovered this building in the Secret realm of Saint Luo, but they discovered there was a "restriction" around the altar, so they used the space they had to bring the building back to its original state. They placed it in their own backyard, but after many years, they could not break it. This means that he just happened to destroy the array and got lucky. This restriction seal? It seems that feng-qin's "true talisman" came from the saint-luo-secret realm. The royal capital!
