His family is stationed at the border, and no one can come to his rescue. A dead end! Jiang Changfeng calmly breaks the seal on the demonic sword inside his heart... The demonic sword devours everything, endlessly strengthening his body: Vajra Sword Body... Divine Demon Sword Body... Four Symbols Sword Body... Undying Sword Body... His sword comprehension grows without limit... One strike brings perfect clarity of sword heart. One practice makes a sword technique proficient, two master it, three make it transcendent, and four reveal the intent to destroy the world...

He holds the power of the world by day and rests in the arms of beauties by night. With the four peerless beauties known as “Wind, Flower, Snow, and Moon” at his side, Jiang Changfeng ventures into the Nine Netherworlds, strides across the Nine Heavens, and sets his sword on the path to eternal life!
