The Xuan Abyss Moon Decree

One hundred and twenty thousand years ago, the Xuan Realm, once the foremost of the Six Great Realms, was besieged by the other five realms and subsequently sealed off from the outside world. This isolation severed its supply of Chaos Qi, making it impossible for cultivators within to ascend to the rank of Emperor Sovereign, while also preventing external Emperor Sovereigns from entering. Following a devastating defeat, the Fallen God returned and massacred the entire city of Yuanlong, yet four siblings, including Bai Lingfeng, miraculously survived. Bai Lingfeng eventually restored his family's glory and pioneered a method to generate a new form of Chaos Qi within his own body, forging an unprecedented path for future generations to break through to the Emperor Sovereign realm.
