The special buildings of the Undead Race, such as the Soul Recruiting Tower, can capture Spirit from the outside world, and then inject it into the energy core of the Castle of the Undead, transforming it into the Power of Death, which in turn induces the production of various troop types.
Common buildings include taverns and markets. The former is used for recruiting hero unit followers, while the latter can link to the Sea of Realms area where it is located, allowing for trade in materials with others.
Thinking of the market, Zi Liyuan glanced around and noticed a resource warehouse, which is the manifestation of the Undead castle's market introduced by Copperbeard·Skeleton Number One just now.
"Let's go check out the market first," he said.
The Castle of the Undead is a product of the Sea of Realms, and this entire Necro Realm was formed after it was separated from the Sea of Realms.
