"Just like that, the Death Energy Tower, as an important part of our defense force, should first be upgraded to the Silver Level. Next would be the Sailor Camp, and most importantly, the Skeleton Conversion Field; it's perfect to elevate both to the Gold Level."
Fang Jie swiftly made his selection, raising the schematics of those buildings, and then he'd address further modifications later.
"So, for the other buildings to be upgraded, let me see. The Corpse Processing Plant is a bit too low level; it can be raised to the Silver Level. As for the Gold Level, it seems that I can only upgrade the Material Warehouse for now."
Fang Jie saw the other buildings, which basically had little value for upgrade.
"What a pity, if only I had another troop building upgrade card, then the Alchemy Workshop would have to stay at this level for now," Fang Jie shook his head, then glanced toward his own dockyard.
