Inside the cultivation room, Lin Xuan began practicing the Celestial Sound Black Dragon Wave. Lin Xuan's talent was very high, and he learned martial arts quickly. However, the Celestial Sound Black Dragon Wave was indeed very difficult. Lin Xuan practiced for five days but still couldn't master it.
The Big Black Dog said, "You're too impatient. Martial Arts of this caliber can't be mastered in just a few days. Even with the help of a fifth-grade cultivation array, you can't master it in such a short time unless you have other treasures."
Lin Xuan took out the scroll and looked at it. In addition to the Martial Arts training, it also recorded other auxiliary methods. One piece of information, in particular, caught his eye: the Celestial Sound Stone. The scroll mentioned that the Celestial Sound Stone was a sound-type Treasure, and obtaining it would speed up the cultivation of Sound Martial Arts.
