Get the artillery ready and shred them to pieces!

This copy of the ❮Sea Urchin Warriors' 20 Years of Mandatory Education Manual❯ was a special edition. It was waterproof, it could resist high pressure, and the characters were fluorescent. Even if they were deep in the sea, the sea urchin warriors could quickly consult the content of those 20 years of mandatory education.

This book was something the Ministry of Education of the sea urchin warrior race had researched and created the year before last. With this book in hand, the younger generation of the sea urchin warrior race could increase their knowledge whenever they wished, even in the depths of the sea.

After quietly taking the ❮Sea Urchin Warriors' 20 Years of Mandatory Education Manual❯, the thin and tall sea urchin elder started to skillfully leaf through it.
