Lin Yuan did not want to create another team for the sole purpose of creating the Spirit Settling Silver Ore weapons because this would expand Sky City's members to too large of an extent.
Besides the fact that it would require Lin Yuan to invest many resources and effort, he would be at odds with the Listening Heron Chamber of Commerce's role.
This was not what Lin Yuan wanted.
Moreover, the Vein Land Imp was like a walking mineral vein.
As such, it might be able to discover other mineral veins besides the Spirit Settling Silver Ore vein.
In order to match up with the speed at which the Vein Land Imp dug through the mineral veins, Lin Yuan would have to form a group with more members than a top faction, as not even a top faction would be able to harvest a mineral vein in a short span of time.
After mulling over this problem, he decided to go into the business of the mineral itself.
