June Fishing Raiders River wild fishing, traditional fishing, carp nest, but no carp, what line group, how big hook, what bait? Pursuit of perfection

Fishing is afraid that there is no fish to catch. It would be great to have fish in the nest. The fish in the wild river vary in size, and the carp is strong. The main line is set at No.3, but you must bring a roulette wheel. You can't lock roulette. In case it's a big fish, you won't have time to get off the line. Line-sized fish cannot be imported. Filter the small fish directly, and use the smallest No.7 izu as the hook shape, preferably thousand, which is the hook shape. Traditional fishing does not use bait. Forgot to adopt!
