Before Rawls returned, Zhang Tie made a dialogue with Heller.
Zhang Tie: Is it okay?
Heller: You're the owner and ruler of Castle of Black Iron, you have the authority to make any decision.
Zhang Tie: How many people could Castle of Black Iron hold?
Heller: Based on the food storage and productivity of Castle of Black Iron, Castle of Black Iron can now hold at most 26,000 people. If 26,000 people entered Castle of Black Iron, half a year later, if those people joined in the production and wasteland reclamation, Castle of Black Iron could hold another 78,000 people. Similarly, if the land area of Castle of Black Iron didn't change, it could at most hold and survive 1,200,000 people in the future.
Zhang Tie: If...I mean, if there are truly so many people in Castle of Black Iron one day, can you manage them?
