Chen Mobai used "The Union of Differences" to methodically channel balanced Five Element Spiritual Energy into the Inorganic Soil within the domain.
With sufficient nourishment from the Five Element Spiritual Energy, it wouldn't take long before this place transforms into high-grade Five Element Spirit Soil.
Chen Mobai planned that after leaving, he would transplant the Five Elements Spirit Tree sapling, currently being cared for by Zhuo Ming, into his own domain and cultivate it to maturity in the shortest time possible.
When the time comes, he could use the same method to replace the Five Elements Spirit Tree within the Yiyuan Mijing.
After completing these arrangements, Chen Mobai left his domain.
If not for the Five Extremes Heavenly Heart Ornament being the key to entering the Yiyuan Mijing, Chen Mobai even considered that this Magic Artifact could potentially serve as the spiritual vein center of a Secret Realm, akin to the Heavenly Bead.
