Military forces had warriors who had been to the Elf World and obtained Moon Well Spring Water.
So Li Guining was no stranger to the effects of the Moon Well Spring Water; even the staff department had discussed the feasibility of obtaining it in bulk.
However, the plan ended as a mere paper discussion.
Because there was only one Moon Well left in the Quel'dorei World, it was impossible to obtain the Moon Well Spring Water in bulk unless they declared war on the Elf Clan.
Among the several uses of the Moon Well Spring Water, upgrading skills was a practical one.
To this day, humans had discovered three or four methods to upgrade skills, but the conditions to use them were very stringent.
The Moon Well Spring Water was one of these methods, another being as rewards for completing World Tasks.
In addition, the Abyss World contained some peculiar items that could upgrade skills, but most were difficult to replicate.
