As the sun sets, a group of children are playing on the beach by the sea, but suddenly they step on something.

"Ahh You've stepped on me, take your feet away!" A little man the size of a thumb, dressed in green clothes and wearing a brown hat, was touching the top of his head that was stepped on by the children, and said with a round face.

"Ahh It's so cute, who are you"?

"Yes! Why are you so small, are you an elf?"

The children were babbling and asking about the cute little man.

"I'm not an elf, my name is Lang Xiaosheng, I am called a kappa by you humans, I can predict the weather!" The villain who called himself Lang Xiaosheng, not only was he not afraid of humans, but he also introduced himself very proudly.

"Who is Lang Xiaosheng"?

"Can you still predict the weather, really"?

The children babbled.

"Of course he can predict the weather, so let me introduce him." Demon slayer," Kayo, suddenly appeared in front of the children and introduced.

"Hey! Big brother, who are you? Why did you suddenly appear here? One of the older children asked Jiayo.

"Me? I'm a demon slayer, and I'm a good friend of this little man." "Jiayou" said happily to the children.

"Who's the villain"? The little monk said to "Jiahe" unhappily.

"Yes! It's a kappa in the sea." "Jiahe" said.

"Humph! But...... You need to hurry home because it's going to rain heavily." The little monk suddenly changed the topic and said to the children.

"Really, fake?"

"I think he's a deceitful little monster, how can it rain when the sun is so big"?

"Yes, I think he's a liar."

Those children, not believing Lang Xiaoseng's words, instead made faces at him, calling him a liar......

But in a few moments, the sky was suddenly covered with dark clouds, lightning and thunder, and in an instant, the torrential rain slanted down.

The children believed the words of the little monk, but they also ran in groups in the direction of home, and after a while, they became soup chickens.

"How? Kappa in the sea, let's go home too, shall we? You have the ability to predict the weather, but later on, you're a chicken." "Jiayo" said jokingly.

"Humph"! The little monk snorted lightly and left with "Jiahe".

To say that how could this "Jiahe" become friends with this Dongying monster and Lang Xiaoseng? To say that when "Jiahe" came here to subdue the "Fish Demon" a few days ago, thanks to his ability to predict the weather, he saved the life of "Jiahe"...... So "Jiayu" became friends with him.

Although "Jiayou" is a demon slayer, he is not, a person who does not distinguish between right and wrong. In the relationship between him and Lao Bai and Snow Girl, he has made him less disgusted with monsters. In the days when he left the Snow Maiden, thanks to the company of Lang Xiaosheng, he was not so sad.

Lang Xiao Monk, also known as the little monk of the waves, inhabits the sea all the year round, and his body is only a small monster the size of a human thumb. Because he is from the same line as the kappa, he is also called the "kappa of the sea".

Although he lived on the coast for a long time, Lang Xiaosheng was more afraid of storms. Whenever it was about to rain, he moved from the sea to the land to settle down for a while, and then returned to the sea when the weather improved. As a result, the residents of the seaside often regard Lang Xiaosheng as a "weather forecaster", and whenever they see him migrate from the sea to the land, it means that heavy rain is coming. Lang Xiaosheng does have the ability to accurately predict the weather in the ocean, and can determine what direction it will rain through the sound changes of the waves. Therefore, some areas also worship Lang Xiao Monk as the god of rain, and when there is an urgent need for heavy rain in the dry season, everyone sincerely hopes that Lang Xiao Monk will come to their village and bring heavy rain at the same time.

But it seems that the "rain god" Xiao Jingteng also has this there!
