After completing She Qingqing's upgrade, with the remaining two options for [Two-Star - Resource Optimization], Lu Ping didn't hesitate to use one for upgrading the Fire Source Stone Vein.
[Optimizing Fire Source Stone Vein...]
[Optimization of Fire Source Stone Vein successful, vein level upgraded to Tier Two Middle Grade]
Upon successful optimization, resource details immediately emerged.
[Fire Source Stone Vein: Tier Two Middle Grade Vein]
[Estimated Income: 35,460 Spirit Stones/year (fully controlled, entering stable phase, sustainable for twenty years)]
This optimization upgrade successfully raised the Fire Source Stone Vein from Tier Two Lower Grade to Tier Two Middle Grade.
The estimated income increased from the original 17,900 Spirit Stones per year to 35,460 Spirit Stones per year.
After all, with the increase in the tier of the Fire Source Stone, its price would naturally rise.
