Importance of the Qi Sage Realm

By not letting the Futanaris sleep during the night either, Bai Long managed to make them completely mine the deposit of Crystal Yin and stored all of it inside his Ring of Darkness. 

With such a large amount of Yin Crystals in his possession, Bai Long could try and create an additional array for every building on the flying ice mountain to further increase the concentration of Yin Qi. 

But honestly, that would no longer be doing something out of necessity or luxury, it would be pure madness. 

Therefore, Bai Long decided that he'd just sell it. 

He'd sell the Yin Crystals and then use the money he obtains to by for the other resources he had a need for right away, or possibly in the future. 

Once he made a decision, Baj Long ordered the Futanaris to not roam around and focus on their cultivation while he would go on this trip by himself.
