Zhou Yi couldn't help but think: "The main steel exports of Steel Refining City are aimed at United City, right? I haven't heard anything about trade with us being stopped on their side, what exactly is the problem?"
"Transportation."
The Steel Refining Lord explained: "The distance from Steel Refining City to United City is far, and along the way, it is necessary to pass through some large ports, navigating along the fixed commercial routes in the Dead Sea. The most important transit hubs, Coral Port and Sixth District, are neither accessible for docking nor for entering."
"Coral Port aside. Although Sixth District is a Guangna City run independently by the Guangna Species, they have close economic and technological cooperation with Mechanical City. Therefore, they are greatly affected. They also forbid our ships and goods from entering and docking."
