章 677: Blood Battle Ocean Resources

Azure Dragon Hall was the first line of defense against the four hostile forces. The Black Dragon Hall was situated five million li to its rear left, while Red Dragon Hall was situated seven hundred million li to its rear right, both considered as the second line of defense. Yellow Dragon Hall was situated in the middle of the three halls and the Dragon God Celestial Palace, and hence was the last line of defense. Usually, it supported the other three halls and was supplementary in nature.
