The first abyss in the earth-elements realm was the main battlefield of human knights and demon knights.
Demons were constantly pouring out of the hollow earth; if they wanted to arrive at the land of the Eastern Continent, they had to break through the Lion Fortress.
As for Taixia Country, the holy war had two battle lines which were undergoing at the same time.
One was in the first abyss in the earth-elements realm; the other was in other continents and subcontinents from where demon corps were constantly pouring out of the earth surface from the underground world.
As for demons, this holy war also had two battle lines. Demons' attack on the earth's surface could be regarded as a siege of Taixia and the Eastern Continent while their attack in the earth-element realm could be regarded that they were going to collapse Taixia Country from inside.
