If possible, it is best to flush the ore first, and then flush the project with the washed ore. After all, the current mine price is really high.

If WLK is used, the project has little impact on MT, but if it is violent PVE or weapon PVP, it will be of great use.

Forging is more suitable for MT, with more holes. However, ICC's 264 equipment was tied up in the later period, so direct trading was of little use.

There are many practical things, such as portable shops, banks, warehouses and so on. . .

Don't expect him to make money for the project. . (motorcycle? Just kidding. . )

If you fly around the map every day, forget it.

Finally: I chose mining+engineering.
