Zhao Hai took a look. The reason why there was such a huge difference between humans and undead creatures was that the ship had rooms prepared for the humans, so it took up a lot of space. On the other hand, it was different for undead creatures. It was like taking a bus, and the ship would load as many undead creatures as it could.
Such a design might be good for others, but it was useless for Zhao Hai. He had the space, so he didn't need to load people into the ship. But no matter what, the design already existed, so there was nothing bad about it.
Most importantly, Zhao Hai wanted to see what kind of price he would have to pay to upgrade the current design of the ship. If he were to spend a few million gold coins, he would have to sell everything he had.
