Two of the most ancient spots in the Celestial Spirit Realm was the Devil's Catacombs and the Heavenly Mausoleum.
The Book he used to erect the Red Wall was from the Devil's Catacombs and the Golden Wall was from the Heavenly Mausoleum.
These two places were in two separate places that had been a landmark for thousands of years. However, they are built in the same place. It was a place where the soil is red and the energy of chaos prevailed.
That place was the Red Lands where numerous kinds of beasts ranging from the weakest Brownhorn Wyvern that was at the first level of Dominion Realm to a Grand Rainbow Serpent at the peak of Celestial God Stage, the Red Lands was the place where the strongest of the Realm resides.
