There isn't much to arrange in the Immortal Realm actually.
Wang Xiaoqiang's women all reside in the City of Heavenly Pride.
The defenses of the City of Heavenly Pride are impregnable, even at the Immortal Emperor Level, they can't break through, and the internal layout is a maze. Even Daluo Golden Immortals entering would be lost within. As long as the women remain inside and don't venture out, they'll be perfectly safe.
So Wang Xiaoqiang simply gathered all the women in one place, informed them he would leave for a while and told them not to leave the City of Heavenly Pride without good reason.
After giving these instructions, Wang Xiaoqiang prepared some things for the journey back to Earth, such as pills that could prolong life. He also carried over ten thousand gold coins, all stored within the Sumeru Ring, and embarked on the journey with the True Person of Taiyi.
