In the seven realms surrounded by the sea of imaginary numbers, the fragments of the divine core left behind by the creation of the two gods are intertwined with the threat of chaos. Mortal resonators use contract emblems to link the divine blood and spiritual breath, playing a symbiotic movement in the rift. From Wa Lin and A Yun's pursuit of the truth about the divine core, to the new stringers Huck and Sura breaking free from the shackles of divine power, the story focuses on the core of "resonance is cooperation" - not the perfectly synchronized divine order, but the courage of human beings to accept differences. When the chaos of the sea of imaginary numbers gave birth to threats such as melody parasites and resonance singularities, the people of the domain gradually awakened: the true law of symbiosis is hidden in the first cry of every soul that dares to reach out, weaving eternal harmony in thousands of imperfect resonances. This is an epic about fragmentation and reconstruction, witnessing mortals growing from fragments of the divine core into their own resonant origins.
