Zhang Fei wanted to gather all the demon materials to upgrade all his wives' demon ranks, but they needed five types of items, and the chance of obtaining each item was slim. Wu Zu could help him concoct the Demon Soul Elixir, but he had to find the other four items himself.
Zhang Fei thought about bringing his other four clones to the dungeon to look for the other four items, but the four perils and their armies had already departed from the Ten Thousand Beast Grave Domain to attack the Dragon-Soaring Divine Domain, so he had no other choice to leave one clone in the Paradise Realm.
Even though the place provided by Hua Qianmei was safe, Zhang Fei could not rest assured leaving his demon wives unguarded, so he left one clone to protect them.
