After Wen Jian displayed his paired Phenomenal Domains, he brought out a longbow. An energy arrow took shape, its core made of Gold Attribute Immortal Yuan Power and its surface covered in Water Attribute Immortal Yuan Power. Feeling the sharp Sword Qi radiating from it, Ling Tian and the others couldn't help praising him. They knew he had infused the sword intent of the Sky-Breaking Sword Drawing Art into the arrow.
Hearing what Old Man Ling said, Ling Tian froze slightly and muttered, "Is there really a difference? I can also make an energy arrow with Gold and Water Attributes that feed into each other. The only difference is that I've infused sword intent into it."
"Hehe, Little Uncle, your eye for detail isn't very good." Mo Lei giggled. Seeing Ling Tian's puzzled expression, she pointed at the tip of the Spiritual Energy Arrow. "Look, Uncle Wen Jian's energy arrow has three little holes at its arrowhead..."
Sure enough, the arrowhead was triangular, and Wen Jian's energy arrow had a little hole at each of its three edges. They looked rather like the hollowed-out sections on his flying sword.
Ling Tian also spotted the holes, and his eyes lit up. He blurted out, "Tsk, tsk, could Brother Wen Jian's energy arrow attack with sound waves? Sword intent combined with sound waves—that's a powerful Soul Attack!"
"That's right. This energy arrow is Wen Jian's own invention. He named it the Whistling Arrow, which is quite fitting." Old Man Ling nodded, then looked at Ling Tian. "Tian'er, don't you think we should put the Whistling Arrow to use? I heard you invented a warning signal in the Barbaric Land. This..."
Ling Tian's eyes lit up. "Exactly! We can use the Whistling Arrow as all kinds of signals, for warnings or other purposes.
