The afterglow of Snow Moon City's Hundred Flowers Festival had yet to fade when a bloodstained fragment of a map to the secret realm of the First Tower Under Heaven suddenly shattered the peace of the martial world. Xiao Se entered the fray with the fragment in hand. Lei Wujie's sword heart stirred for the first time, while Wuxin ventured back into the mortal world. Their new companion, Zhuge Yue, joined them with the mechanisms of the Hundred Dawn Hall, and the young heroes were swept into a shocking maelstrom spanning both the martial world and the imperial court.
The Netherworld Manor rose from the ashes, the Temple of the Fire God launched an eastern campaign from the Western Regions, powerful nobles at court secretly colluded, and forces from every kingdom watched with covetous eyes. Behind layers of intrigue lay a disturbance in Beili's dragon veins, the cruel secrets of artificially attaining the Divine Wanderer realm, and the truth behind the world's waning spiritual energy, which the First Tower Under Heaven had been suppressing.
From the raging seas off Penglai to the bloody battle at Jianmen Pass, from the schemes in Tianqi City to the nation's grief in the Northern Frontier, and finally to a secret realm hanging upside down, sustained by the dragon veins, the young heroes crossed mountains of corpses and seas of blood and faced the demons within. They grew through choices between friendship and betrayal, personal ambition and the welfare of all under heaven. Xiao Se entered the Dao through wisdom and mastered the carefree art of riding the wind; Lei Wujie's clear sword heart summoned the Sword Intent of Seven Emotions; and Wuxin found enlightenment in the mortal world and reached the realm of the Tathagata. Together, they fought the Netherworld Manor's master, who sought to defy fate, and battled terrifying monsters created through artificial ascension to the Divine Wanderer realm. Before the ultimate trial at the ruins of the gods, they stood at a crossroads where the future of martial arts would be reshaped.
What is the way of the hero? It is neither following ancient customs nor clinging to old rules, but letting one's heart decide where to go. This time, with swords in their hands, wisdom in their minds, and justice in their hearts, the young heroes will uncover the ultimate secret of the First Tower Under Heaven, define a martial world of their own, and compose a blazing tale of youthful adventure in The Blood of Youth!
