"When the Fishmen attacked the island, one of the elders from the Purple Vine Chamber of Commerce took action and successfully seized the Iron Lump. Afterwards, during the battle with Ya Ma, he was forced to use Undead Magic, thus revealing his identity as an Undead Mage."
"At that point, our side finally realized that among the two Purple Vine seventh-level elders, there was a Silver Level Undead Mage."
"However, to tell the truth, I wasn't very surprised."
"Because before its reorganization, the Purple Vine Chamber of Commerce indeed had many secret ties with those Undead Mages."
"From another perspective, if there were any remaining forces of the Purple Vine Chamber of Commerce after the reorganization, they must have utilized the hidden abilities of the Undead Mages to hide and avoid being purged."
