Craftsman Puzzle

A piece of ancient jade that was sold awakened the secrets that had been buried in my uncle's letters for half a lifetime. To solve the mystery, I set out on my journey. Lin Yi remained silent. Tao Lingyi, who has all the connections and financial resources. There is also Wen Jianzhi who is familiar with ancient books and inscriptions. Is the encounter destiny or man-made? The four of them each go their own way and travel together to old places all over the place. What kind of secrets are hidden in the undercurrent? I just wanted to make up for an old story, but I didn't know until I was deeply involved in the situation—— This game that lasts for several generations had already reserved a place for the four of us when this jade appeared.
