"Really strong!"
It was clear that just based on this special effect, it already outclassed those ordinary city walls by a mile.
Moreover, the upgrade materials listed on the blueprint were simple.
The [Ice Glacier Fragment] material, through several previous trades, was already nearing a million.
Even upgrading all the city walls in the territory would be more than enough!
As for the [Basic + Intermediate Frost Arrow Tower Blueprint], these two types of arrow towers had attributes similar to [Ice Arrow Tower], with the difference being an additional effect of [Frozen Aura], reducing enemy attack speed by 10% near the tower.
So Cao Xing didn't pay much attention to them.
Next up was the treasure box he eagerly anticipated.
On the bluish stone floor in front of him, a glowing box appeared.
As he approached, the system prompt appeared.
[Discovered Golden Treasure Box reflecting cold light, open it?]
"Yes!"
[Successful opening]
