Yuchi traveled to the wild and ferocious world, where the heroes of all races lived in the world, and was arranged to be put in prison by others since he was born.

When others have completely forgotten this little transparent thing, he has already taken out the bamboo pole that accompanied him in his previous life.

There are souls of ancient gods and beasts in the vast wilderness of the world, rivers and seas.

This bamboo pole can communicate with ancient times.

Go fishing in the Nether Dead Sea and get the Lament of the Naga Siren!

Fishing in the Bone Ning River, get the onslaught of Mourning Murlocs!

Go fishing in the cave sky and deep pool, and get the golden pupil of the five-clawed dragon!

Hang candles in the sea and sky to fish, and get the real fire of the nine-tailed white fox!
