The gap between Five Treasures and Four Treasures of the Study is indeed quite big, but there is still an important process to improve the magic weapon, which is to improve the speed of the Silk Road and achieve the qualification of replicating and upgrading the country.
Especially after the average, the accumulation of one and a half investment orders every day is a great improvement.
According to the current depreciation rate, the promotion of the magic weapon has been accelerated a lot, not to mention the promotion of the magic weapon and the role of donating shadows in the national war will be higher.
Personally, the best way to upgrade is:
100 magic weapon → five treasures → butch → treasure.
Complement each other and increase each other, which improves the speed of obtaining treasures to a certain extent.
The most boring thing in the game is that you can't continue to get the experience of level 9 or above.
