Dragon Chair in the Forbidden City: Even if you pay, experts wouldn't dare touch it!
Dragon chairs are symbols of the power of the emperor, so the materials used to make them are not ordinary!

A golden nanmu tree costs as much as several mansions, it is extremely rare but no merchant wants to invest in planting it, why is that?
Strange tree known as king of wood, harder than steel, bulletproof
Even when shot with a bullet, the bullet hitting the tree only leaves a faint mark, unable to be shaken.
