Actually, installing Magic Shields was no small expense compared to buying ships, but there was no alternative. At this stage, it was too difficult for the guild to get a warship.
If it hadn't been for the turnover of warship models, coupled with the relationship with the queen, it would have been nearly impossible for Li Yao to acquire a warship.
For a long time, Starfire would have to rely on these warships to protect the safety of Starfire merchant ships, and they might even have to battle pirates. It would be very troublesome if they were lost and couldn't be replaced.
Therefore, Li Yao insisted on installing Magic Shields, and in fact, if Magic Shields were installed, Sister Li wouldn't have objected.
But using Magic Shields was too expensive. The materials for Magic Shields weren't available to players at this stage, and they could only be purchased at high prices from NPCs.
