Sages cultivate the path of ruthlessness. But when the Heavenly Dao crumbles, the days when sages could not die become a thing of the past. When calamity strikes the world, the sages are driven to the brink, unable to reopen chaos and create a new world. They abandon the glory of their sagehood to give the primordial world's living beings a glimmer of hope.
Liu Er the Macaque, an outlier among demons, has six ears and is skilled at listening. He can discern reason, know what came before and what comes after, and understand all things.
Yang Jian, the celestial world's God of War, has a third eye that sees truth from falsehood and breaks through demonic illusions. He excels at transformation and masters every art.
Chen Yixing says, "My big brother is Liu Er the Macaque, and Yang Jian is my second brother. Come see how I pass down our tradition in a lesser world, suppress demons and invest the gods, seek the Dao and challenge swordsmen, forge the Nine Cauldrons to stabilize the world's fate, become the greatest immortal of all time, then break into the primordial world, contend with the mighty, and save both realms."
