Heaven, Earth, Spirit, Body and Qi, he was trying to establish five top-notch Dao Foundations at once. The expenditure of spiritual qi was beyond immense.
He was like a black hole, crazily absorbing the spiritual qi of the outside world. In addition, the Yin Burial Coffin also advanced at the same time.
With two spiritual qi black holes, the exaggerated suction force caused the earth vein to reverse the flow of spiritual qi.
Under the corpse of the Ghostwood Demon King, dense Yin qi was drawn in.
The Yin Burial Coffin refined and absorbed it endlessly, forming a pure Yin Burial spiritual qi. The Yin Burial spiritual qi was absorbed by the Nine Nether Wood and transformed into an even higher-grade Nine Nether spiritual qi. In the end, it was absorbed by Jiang Li who was hiding in the trunk of the Nine Nether Wood.
