Yun Qihe returned with a broken soul, stained with blood on the heavenly steps, and cut off the fate of the three realms with one sword. Su Zhaoye, who was regarded as the Son of Destiny in the past, had long been transformed into a remnant soul in the furnace of all calamities, but on the night when Yun Qihe tore the sky apart, he resurrected his soul and defied fate. The two were old enemies, but they were forced to coexist due to the mismatch of destiny - Yun Qihe held a sword to ask the sky, and Su Zhaoye swallowed souls and cast bones. One wanted to destroy the sky, and the other wanted to kill the gods. When the nine heavens collapse, who is the real destiny? Is it Yun Qihe who holds the soul-breaking blade, or is it Su Zhaoye who hides in his bones and whispers "You should have died"?
