Become the Master of the Ocean, Start by Raising a Mermaid

I started watching it last night and just finished it now. Let me start with 1 point: This book is terrible (ц｀ω´ц*) The first half is okay, but the second half... Gets worse as I write more. In short: if you don't mind reading half of the book, you can look at the front, the real ψ(｀∇´)ψ at the back

The first half is okay, but the second half is not okay from the last 240 onwards. It's not that good. Besides, the ending is too fast.

I don't want to write anything later! The plot ends like this

This protagonist is really awesome(^o^)ノ． ． ． …___●Thunder

Let's not talk about whether the writing is good or not. Even if it is a eunuch, it will be fine. This kind of random ending is the most annoying.

Average, not great

The ending is too silly
