When the heavy rain tore through the city sky, twelve obsidian obelisks weaved the starry sky into a cage, and the unsealing key in the palm of young Lin Yu resonated with the twin hearts - he did not know that he was already the twin container of the fate of light and darkness. The strange pulse of the Lord of Star Bones penetrates three hundred years of time. The mechanical minions of the Blood Alliance are watching in the shadows, and the Star Bone Bracelet on his mother's wrist is leading him to the ultimate mystery under the deep sea.
The golden-red sword blade split the ruins runes, the electromagnetic bracelet unfolded into a three-meter giant sword, and the light and darkness swirled to shred the roar of the mechanical puppet. Lin Yu pieced together the broken memories during the battle: his mother was dragged into the dark mine veins by the mechanical arm, the promise made by Su Qing's soul fragments burning in her body, and the seal secret locked by the heart of the first-generation priest. When the twin dragon swords and the star core scepter resonated with the light of the Möbius strip, he was shocked to realize that the truth of the symbiosis of light and darkness was actually the ultimate key forged with blood and memory.
This is an interstellar conspiracy that spans centuries, and it is also a young man's journey to find himself amidst the torrent of swords and data. When the electromagnetic compass pointed to the giant structure in the deep sea, the ancestors of the men in gray feather cloaks threw their core consciousness into the abyss. Lin Yu held not only the twin dragon swords, but also the unfinished oath to "guard the stars" with Su Qing. In the game between the mechanical transformation and the ancient priest, can he use his heart as the key to let light and darkness coexist in contradiction and end this fateful battle throughout time and space?
The fateful showdown between light and darkness, the resonance battle between machinery and blood - the awakening of the twin vessels begins from the moment you hold the dragon sword.
