Liu Changxun had no intention of giving Bai Zhizhan time off, nor did he wish to treat him to the Saiyi local flavor, but instead, he wanted him to accompany Zhao Yu on an inspection tour of the Daban Shipyard.
In fact, this included the shipyards at places like Shenhu as well.
Even though the Saiyi Imperial Kingdom had been defeated and the Imperial Authority had no plans to reconstruct the Saiyi Imperial Kingdom or, in other words, take advantage of Saiyi industry, the shipbuilding industry of the Saiyi Imperial Kingdom was not at all outdated, and much of the infrastructure had been completely preserved. Even if these were not used to build battleships, they could still be used to repair battleships or construct civilian transport vessels, especially oil tankers, which would definitely be needed in significant quantities in the future.
Moreover, there were many unfinished battleships in several Navy Shipyards.
