A tsunami causes the capital to become very cool. The capital was already a pretty cool temperature, but with the addition of the water from the tsunami, the capital is now very cool.
You don’t like how cool it is in the capital now so you decide to get in your row (りょう) boat and row away to some place that is not so cool. Get in your row boat and row away!
