Millennium Thunder Copper.
This is the treasure material discovered by Little Star Monarch Xiang Zhao.
This discovery comes from another identity of Xiang Zhao — the Star Harvester.
The Star Harvester didn't appear suddenly; it actually has always existed.
It's an upgraded version of Mountain Seeking and Sea Exploration.
When Xu Jin was in Kunling Domain, forces frequently organized Mountain Seeking and Sea Exploration, aiming to gather Heavenly Materials and Earthly Treasures, rare spiritual medicines.
It's both a search for supplies and a way to get rich.
This Mountain Seeking and Sea Exploration occupation has long been established in Dongxuan Star Realm and other Star Realms.
However, the threshold for Mountain Seeking and Sea Exploration is low; anyone with a bit of cultivation can do it, but many do it, and the rewards are few.
But star harvesting is different.
