"At this rate... won't it take a whole year for Huanyu City's Fire Seed to become a Tier Eight Fire Seed?"
Looking at the progress bar on the upgrade panel, Huang Yu pursed his lips and suddenly felt rather weary.
It had taken a month for the Fire Seed to upgrade from Tier Six to Tier Seven.
But upgrading from Tier Seven to Tier Eight would take nearly a year.
"This is where the Upgrade Acceleration Card comes in."
Huang Yu took five cards out of Anchor Space.
These were special items he had purchased from other lords. Three of them were Upgrade Acceleration Cards.
Two provided threefold acceleration for one month, while the other provided fourfold acceleration for half a year.
The three acceleration cards alone had cost Huang Yu over ten million Soul Crystals.
Huang Yu planned to use the two one-month, threefold acceleration cards. As for the half-year, fourfold Upgrade Acceleration Card, he intended to save it for when his territory reached Tier Nine, or when he urgently needed to increase the level of a particular building.
Ding!
Threefold Acceleration Card (one month) has been used! Threefold Acceleration Card (one month) has been used! Current acceleration duration: 2 months! Current upgrade progress: 0.0...67%!
Seeing that the upgrade progress had clearly accelerated, Huang Yu expressionlessly closed the Fire Seed interface.
The upgrade boost from acceleration cards could not stack; it could only extend the duration.
Therefore, even after using two acceleration cards, it would still take more than half a year for Huanyu City to upgrade into a Tier Eight territory.
Buzz—buzz—
The Communication Device began to vibrate.
Huang Yu answered the Communication Device, and immediately heard Zhuge Jing's voice.
"Lord, there's urgent military intelligence from Xisha Province to report."
