The thing that came out of the water was something giant, so big that it could completely cover up the ship.
What came out of the water was the tail fin of the whale.
It came up above the surface of the water, but it didn't touch the boat at all. The tail fin was just a little bit away from the boat and if it was just a tiny bit closer, it definitely would have tipped the boat over.
The tail fin came high up into the sky, way up above the boat. It continued all the way up until it couldn't go up any further.
The tail fin of the whale stayed up in the air for a few seconds before it suddenly changed directions and started falling down.
Lin Fan and Mo Ze Chen had been confused why the tail fin of the whale had suddenly come out of the water, but the moment they saw it reach its peak, they immediately understood what the whale was planning to do.
