Blackgold Wood.
Deep in the universe, there is a special star system where every celestial body is made of metal. When these bodies break apart for various reasons, they transform into Blackgold Trees. The piece of wood before them was a small section of a branch from such a tree. A complete Blackgold Tree could fetch an extremely high price at auctions in the Immortal Domain. It was a supreme material for forging weapons or array setting, so rare that it was often priceless and simply unavailable for purchase. When forging, adding a segment the size of a fingernail could increase a weapon's durability and sharpness by thirty percent.
Xu Lai hadn't expected that such a large section of Blackgold Wood could actually fall to the ground. Was it an accident? He didn't dwell on it and immediately raised his bid. "Ten million."
