The closing season of Xingchen Bian begins when Mount Tianzun descends and the Spiritual Treasure Cauldron emerges, pitting the God-Kings against each other in a frantic scramble for three powerful seals, known as the Azure Heaven, Earth, and Ten Thousand People seals. Qin Yu, recently a father, joins the fighting and faces formidable opponents including the Blood Sea Queen, all to rescue his brother Hou Fei. As the seals change hands and the violence grows, he unleashes power that leaves the gathered heroes shaken. Across 12 episodes, the ONA mixes action, adventure, fantasy and romance.
