Wangwu Zheng Jingzhu's question was actually something that Maoshan had considered carefully.
Whether to let the Spiritual Spring benefit all beings was a matter of great controversy within Maoshan.
Reluctance to part with that bit of Spiritual Energy was one aspect, but the key issue everyone thought of was, if we release the Spiritual Spring like this, others will definitely think: if you only have four Spirit Stones, you wouldn't possibly waste them like this.
It's a very practical issue. In The Secular World, philanthropists being eyed for their wallets is not uncommon; in fact, it seems to be becoming the norm.
But Tang Tianshi had his own considerations. He believed that, for Maoshan, this was a rare opportunity for development.
During times of peace, with the people wealthy, those inclined to the Dao would certainly increase — at least until the end of the tax exemption policy.
