3553. The First Layer of Seal of the Demon Refining Knife

Yan Chengfeng picked up the iron box and gently opened the lid. For a moment, a strong cold air filled the stone room. Even with Leng Xuan's level of cultivation, he couldn't help but shudder. However, at this moment, the Heaven-defying Art in his body suddenly started to operate on its own, absorbing all the cold air around him into his body, and then transformed it into thick true energy and stored it in his dantian.

As if he felt something, Yan Chengfeng suddenly turned his head to look at Leng Xuan, and said in slight surprise: "Can you absorb this cold air?" Leng Xuan was also very surprised, spread his hands and smiled: "It seems like this."

Yan Chengfeng murmured "strange" and said: "Although this Xuanyin Stone contains a huge amount of spiritual energy, its nature is too cold and cold, and ordinary people cannot mix it with it. If it is used forcefully, there may be consequences. Unless you are like me, you will not have this worry if you practice Yin skills." At this point, he added another question: "Boy, do you feel any discomfort?"

Leng Xuan shook his head and said, "No." After saying that, his heart couldn't help but move. In addition to the Heaven Defying Technique, he also practiced another technique, the Nine Suns Casting God Technique. This technique has a unique effect. Not only can it speed up the absorption of spiritual energy, but it can also transform any form of spiritual energy on its own and collect it for use. Although the Jiuyang God-casting Technique has been integrated with the Heaven-defying Technique, this effect has not been degraded. He has always been curious about the Jiuyang God-casting Technique, but after asking many people, no one knew the origin of this technique. At this moment, facing a legend in the world of cultivation, Leng Xuan secretly hesitated whether to ask him.

At this time, Yan Chengfeng reached out and took out the Xuanyin Stone from the box. I saw that Xuanyin stone was about the size of a fist, completely dark, with clear water chestnut corners, and as bright as a mirror. From the outside, there is nothing unusual about the belt. However, when he stared at the Xuanyin Stone for a long time, there seemed to be a strange and mysterious suction coming from the Xuanyin Stone, seducing his soul. Seeing this, Leng Xuan quickly moved his eyes away, shook his head secretly, and calmed down. At this time, Yan Chengfeng turned around and asked, "Leng Xuan, do you want to feel the power of Xuanyin Stone?"

As soon as he finished speaking, he threw the Xuanyin Stone directly into Leng Xuan's hand. After receiving the Xuanyin Stone, Leng Xuan felt that the Heaven-defying Art in his body was running wildly, like a beast that had not eaten for a long time, greedily devouring the cold air in the Xuanyin Stone. At the same time, he felt a vibration in his heart, as if something was calling him. He concentrated for a moment and finally discovered that what was calling him through his mind was the Demon Refining Knife he had obtained not long ago. After hesitating for a while, he simply summoned the Demon Refining Knife. As soon as the demon refining knife came out, the cold air that was originally sucked into the body was directly transferred to it. Moreover, with the injection of cold air, a faint black light gradually appeared on the blade of the Demon Refining Knife, and a violent and powerful aura suddenly filled the stone room.

The Earth Spirit Beast exclaimed: "Boy, what are you doing? Old Ghost Yan, stop him quickly." Yan Chengfeng waved his hand very calmly and said: "Don't panic, the knife in his hand seems to be sealed. It is now being unsealed through the cold air of Xuanyin Stone."
