Niantang Mountain.
When Tang Ruowei followed Chu Ning to the spiritual fields, her cute face never lost its surprise.
East Sea Domain.
It's a domain lacking in spiritual medicine.
The coastal area is not suitable for many spiritual medicines to grow, so cultivators from the East Sea Domain have to spend a vast amount of spirit crystals to buy spiritual medicine and elixirs from other domains every year.
Of course, one should 'use the mountains if they are near mountains, use the sea if they are near the sea.'
After fighting with the Sea Tribe for so many years, they also learned to sell the demon cores and flesh of the Sea Tribe in other domains to offset the consumption of spirit crystals.
Even so, when faced with spiritual medicines from other domains, cultivators in the East Sea Domain would still feel envious since cultivating spiritual medicine doesn't require risking one's life, but obtaining Sea Tribe corpses and demon cores does.
