This day,
beside the Spring of Mimir, Su Lun was hanging upside down on a withered tree, swaying with the wind.
His body, pierced by spears, was riddled with holes, and the blood that flowed within the alchemy formation had congealed into black clots.
For nine days, not a drop of water nor any food had touched his lips, and he hung from the branches like a pale corpse.
Yet it was this very act of sacrificing himself that immersed Su Lun in an extraordinary state.
As if through the alchemic formation's sacrificial process, he briefly merged his consciousness with the entire world.
In those eyes that had not closed for nine days and nights, the secrets of the world manifested as falling runes,
Finally, the light from the sacrificial alchemical formation slowly faded, and the mystical state enhanced by the Spring of Wisdom gradually left his body.
Su Lun's consciousness slowly returned from that mysterious universe-traversing condition.
