「艦隊これくしゅん」Early Spring Event 2024 E-3M Boss Node

Another submarine ops, exactly like in E-2 and it's even worse.
In the end I was sent home so much that I couldn't bother to record the pre-boss nodes anymore. It was such a waste of time. I hate it.
In this event the submarine parts are easily the worst, and this is not the worst of it too.
