After the first vanguard team returned with losses, several Master Level Spirit Masters from the Spirit Control Bureau and Hongmeng Group formed an investigation squad to enter the secret realm within the Xiao Village sinkhole for investigation.
Soon, they discovered that this secret realm was akin to the Bone Wasteland, equally remnants of some ancient battlefield, inhabited by countless undead creatures with little value.
Due to the aura of the living on the investigation squad members, they were quickly attacked by nearby undead creatures.
These undead creatures formed an Undead Army and launched continuous attacks on them.
Among them were no shortage of Undead Monarchs and even Undead Dominators; coupled with their undead trait, this Master Level investigation squad nearly met with total annihilation.
