This world is called Xuantang Continent. Fifty years ago, there was a sudden change in the sky and the earth. Water from the sky poured into the earth and springs gushed out, and 70% of the land of Kyushu became a great swamp. Fish become spirits under the nourishment of water aura. Ordinary fish turn into spirit fish, spirit fish turn into war fish, and war fish can tear tigers and leopards alive. Human beings learned fishing skills and martial arts from the ancient fishing book, and used fishing rods as weapons to barely hold on to the remaining 30% of the land. It is a pure and refreshing article, an imaginary world, and a novice is on the road. I hope all readers will bear with me. The introduction is weak, so please move on to the main text.
