Zhao Hai did not dare to let his guard down when facing an old monster like the yin Wind Ghost emperor who had lived for countless years and fought countless battles. When he stored the underworld God Hall into the spatial city, he had already analyzed the underworld God Hall with the universal analytic machine. The design and construction of the underworld God Hall were not for the sake of looking good, but for the sake of battle.
When the underworld God Hall was built, many arrays were set up inside. These arrays had different functions. Some were specifically targeted at the undead creatures so that they could follow ghost emperor Yin wind without any hesitation, while some were used to enhance ghost emperor Yin wind's mental attack.
