Li Yuanqing, who was in the cave, didn't feel any danger at all. He had just lightly tapped all the treasures in his hand. He was holding a strange-looking bamboo tube and flipping it up and down.
This bamboo tube was completely green and looked very much like an ordinary bamboo joint. However, this thing was not ordinary at all.
Although the aura emitted by this bamboo tube was very well hidden, if one looked closely, they would be able to see that this thing was actually a genuine magic treasure.
The biggest difference between magic treasures and magic tools was whether they could communicate with the spirit.
High-level magic treasures could even give birth to their own spirit bodies.
This bamboo tube did not give birth to a spiritual body, but it did not have spirituality. Li Yuanqing had only played with it for a while and had roughly figured it out.
This bamboo tube was actually a bamboo array.
