For seven hundred years, he was the Azure Dragon of the Land of Endings, wearing a cold dragon-head mask and serving as the Heavenly Dragon's sharpest blade. The bronze bell rang through seven hundred and thirty-one cycles of reincarnation, while the fading image of his sister grew into a scar deep in his memory. Then an old photograph, still warm with the touch of the living, triggered an "Echo of Time." The scene of Qi Xia parting from his wife shattered the numb facade he had worn for so long. The Five Elements Keys lay buried beneath the ruins, and the Zodiac factions became a battleground between slaughter and conscience. Armed with the dual powers of "Wind Control" and "Time," he faced the Heavenly Dragon's threat of death on one side and the rebels' blood-sworn pact on the other. When madness-marked veins crept up his neck and former comrades fell before his eyes, the Azure Dragon finally understood: the end was never the end of reincarnation, but the beginning of breaking the rules. He would make the wind his blade and memory his guide, ringing the bell of homecoming for every lost soul at the heart of the Five Elements storm, even if the price was becoming the last blue echo.
