Amon wasn't discouraged. A runic weapon was usually the plaything of a Martial realm practitioner. His cultivation was still too low. He was not sure if this Xian cloth was in the low-tier or high-tier of the runic grade. He would need a skillful appraiser if he wanted to find out. However, he was not going to do that and let others know he had this treasure just to satisfy his curiosity.
He tried experimenting more with the cloth. He found it could move following his control to a certain degree. The cloth could spin on its own or move around his body. It was exactly as depicted in the mural. Perhaps this cloth was used by dancers in the past for entertainment purposes. But in his hand, he could turn this into a weapon. He just needed to get used to it first.
He took out his swan dagger and tried stabbing and cutting the cloth. The cloth was unscathed. Its material was very sturdy. If he wrapped this cloth around his body, it could serve as armor.
