The potential to become a First-Level God at minimum—not by inheriting a Divine Position—was so rare that fewer than a handful had emerged on the entire Douluo Planet over the past twenty thousand years.
In the era ten thousand years ago, there had only been three human Soul Masters who transformed into undead Soul Beasts and lived a second life: Ji Juechen,
Huang Jinxu, and Xiao Xiao.
Ji Juechen possessed a heart devoted to the sword, Huang Jinxu possessed the Heavenly Calamity Lone Star Martial Soul, while Xiao Xiao was the first Soul Master in the history of the Douluo Continent capable of using Twin Martial Souls simultaneously.
Strictly speaking, Xiao Xiao was both the first and the last Soul Master capable of using Twin Martial Souls at the same time.
Little Dragon God did not count, because that guy was not human to begin with.
Xie Xie did not count either, because his Same-Type Twin Martial Souls were not genuine Twin Martial Souls.
Based on the Three-Life Soul-Suppressing Cauldron Martial Soul, Meng Xinghe incorporated mythological elements from his previous life and forged the divine artifact that suppressed nine earth-vein nodes—the Mountain and River Nine Cauldrons!

At the same time, the person responsible for guarding the nine earth-vein nodes was Xiao Xiao, a peak Quasi-God with Divine Origin Realm spiritual power and a Four-Word Battle Armor Master.
With the Three-Life Soul-Suppressing Cauldron Martial Soul connected to the Mountain and River Nine Cauldrons, Xiao Xiao could use the power of the Mountain and River Sealing Formation to teleport to any of the nine earth-vein nodes
