Abyssal Qi
The Thousand Mountains collapsed as Fu Yiya predicted but the time and lives of the survivors were different. More than half of the Sword Cemetery people were still alive, including the minority of the Master Realm and some of the demons. Additionally, the Demon Lord that was buried under the ocean in the far east by the impact was also still alive.
After falling from the tall mountain that used to be the hiding place of the stairs connected to the Heavens Realm in the past, the old connected areas were gone. The heat and Qi that were crushed down created a large highland in replacement. At the center of the highland was a gigantic sword plunged in it. Sometime later, those who passed this place could not even see the tall handle of the sword through the white clouds, so they named this sword…the Divine Sword (Like the academy’s name).
