The Heartless God King of the Immortal Realm

In the Immortal Realm, within a golden domain, Gu Wuxin cried, "Azure Cloud Sword Art, First Form: Azure Cloud Slash!" He raised the azure sword in his hand and swung it. At once, the wind howled through the surrounding space, and streaks of sharp azure light shot toward him. Gu Wuxin formed a seal with his left hand and murmured, "The true meaning of the sword, the true meaning of the Azure Cloud Sword." He closed his eyes and exhaled, gathering all the sword energy in his body into a single point. With a breath from Gu Wuxin, the azure sword blazed with light, and streaks of azure light burst from its blade like green snakes, shooting in every direction. A fierce sword intent surged into the sky, snapping the trees throughout the valley. Gu Wuxin stamped his right foot, sending dust flying from the ground and transforming it into a gigantic sword. The enormous sword was a full zhang wide, pitch-black from end to end and radiating a frigid gleam. Gu Wuxin opened his eyes slightly and looked at the scene before him, the corner of his mouth lifting in satisfaction. Even a Golden Immortal-level expert would have a hard time getting the better of this move, wouldn't they?
