Deep inside Gu Qing Shan's Thought Sea.
His soul vessel had manifested into a solid form, standing on one side to observe the final sword strike being performed.
-------although it was one sword strike, he had actually used both the twin swords Heaven and Earth during it.
Trillions of Prayers drifted above the Heaven sword and emanated a strange summoning call.
Countless milky white fragments seeped out from underground, drifting within the sword-infused wind following Gu Qing Shan's swings manifesting as unique runes.
They were world origin runes!
These were the origin that created this world, born from the secrets within the Primal Chaos, naturally manifesting as mystical runes.
-------the remnant world spirits, after absorbing the power of the Soul Shrieker and the Era of [Chaos], had been forged by Gu Qing Shan's sword dance into their original essence.
