The Anti-Ancient Realm is a special realm for an Ancient Realm fleshly body. It is a realm that is the complete opposite of the Ancient Realm where the person instead of having to extinguish their Soul Lamps have to ignite them.
Door of the Anti-Ancient RealmEdit
It was completely crimson radiating an ancient, primordial aura which causes seawater to boil. It seems to represent Heaven and Earth and the will of the Mountain and Sea Realm. 
- It is considered a taboo in the cultivation world, so much that the last time it appeared, all Paragon experts of the Paragon Immortal Realm (former Mountains and Seas Realm) destroyed the cultivator and any traces/records of him they could find.
