This explanation seems to make sense too. The benevolent demon of the Nine Heavens Great Freedom Demon is truly formidable, their scheming so deep that it warrants caution. If they hadn't prepared for the worst, leaving the book of life and death to the successor of the Revolving King to gamble on the final chance, they might have immediately suffered a complete loss.
This is the terrifying Chen Shan, the benevolent demon corpse of the Nine Heavens Great Freedom Demon! However, this time the underworld has made a full effort in its layout, even calculating Dizang into the equation. Therefore, it is absolutely impossible to suffer a complete loss, even when facing the benevolent incarnation of the Nine Heavens Great Freedom Demon King; the underworld will surely win!
