Harvey's understanding of the sea demon is limited to the impression of the last world and some folklore in this world. However, there are few Mermaid legends in this world. Most of them are spread among sailors about how the sea demon used songs to trap human beings. According to the old sailor's experience, the best way to distinguish a mermaid from a siren is to look at its ears. The mermaid's upper body basically maintains a complete human posture, so the ears are similar to human beings, and a few of them have sharp ears like elves.

The ears of the sea demon are all similar to the fins. This little girl clearly has the exclusive fin ears of the sea demon.

Harvey took time to go to the harbor to ask the old captain about many legends of the sea demon, and then went to the Elroy library to look up the information. Combined with the attribute information in his mind, he still could not judge the specific category of the sea demon.

"Probably a rare species of the sea demon?"

Harvey is holding a small fish in her right hand, just to the height that the little sea demon can't reach. She is a little worried. She is about to climb up with Harvey's suit in her small hand, and at the same time, she wants to bite the small fish in Harvey's hand with her small mouth open. When she is about to arrive, Harvey raises her height again. She is not angry and is still a little happy.

"Er ~ Er ~ Er ~ Er ~ @... #% & amp; * #%... @" She uttered a murmur of unknown meaning, and the pale blue fish's tail rattled the floor.

Harvey took the opportunity to observe her mouth and teeth. Her mouth had been damaged by the sword of Captain conch, and her tongue had not yet grown out again.

"The mouth is still a human structure, and the teeth are neat and smooth, not like the sawtooth of a sailor."

Harvey let go of the little fish, and she grabbed it. Harvey had tried to feed her other food, but she couldn't get used to it on land, especially sweet food. Every time he ate sweet food, he would spit it out. Then he observed Harvey's look and decided not to eat it. No matter what Harvey's personal feeling or the property panel shows, the little girl like sea demon is not a threat. Harvey asked someone to buy a batch of materials, and then used the alchemy workshop to make a large glass fish tank. When it was filled with water, it became her home.

During the day when Harvey is watching, she can come out for activities. At night, she needs to fix the lid to prevent her from running or making dangerous actions.

After more than a week, the little siren is about to become Harvey's follower.

Harvey put up her body and carried it back to the glass aquarium. The whole aquarium was about one person high and the size of a bed, with sea sand, seaweed and some beautiful stones in it. After diving into the water, the sea demon stretched out her head and shook her hair. The splashing water wet Harvey's suit. The sea demon's round eyes were staring at Harvey. It was hard to associate her with the cruel monster.

[animal training]

Harvey sang a few awkward syllables. After casting the spell, the meaning of every move of the little sea demon became obvious in his eyes. Harvey thought for a moment and asked, "do you have a name?"

The sea demon couldn't understand Harvey's words, but he could understand the meaning. He shook his head blankly. It was not that he didn't have a name, but that he didn't understand the meaning of the so-called name at all.

Harvey pointed to her and said solemnly, "lily, this is your name from today on."

He pointed to himself, "Harvey."

Point to her again, "lily."

She shook her head as if she didn't understand. Harvey repeated several times to confirm that she knew the meaning of the name and rewarded her with a small fish. Seeing her lovely appearance of eating fish, she couldn't help rubbing her long soft blue hair. It felt very strange. It felt cold and greasy like sand. It had a certain weight, and it would flow away like liquid in the palm of her hand.

"Her hair should be heavier than the water, so it won't float in the water."

Lily enjoys Harvey's touch. When Harvey pulls out her hand and leaves, she still clings to Harvey's hand and puts it on her head, rather enjoying the temperature of his palm.

Harvey continued to study magic crystal, and every day he took time to check Lily's mouth injury. When food was sufficient, she recovered quickly, and her tongue grew back in less than a week.

On this day, Harvey first closed the space door of the mage's tower, and then carefully sealed Lily's big water tank. The glass is made of triple reinforced glass specially made by the alchemist's workshop, and its hardness can withstand the continuous impact of several tons. There is a finger sized hole on the top of the glass fish tank for breathing and sound transmission.

"The channel of the mage's tower is closed, the magic crystal is ready, the recording function is intact, and it is expected that the interference song will be played in five minutes, so the test can start." Harvey takes a deep breath, uses [animal training] to communicate with lily, and orders her to sing.

Harvey's caution is not unreasonable. It is also said that the sea demon will show his true face only after capturing the enemy with song.

Lily's tail wags more, which means she is in a good mood. I don't know why Harvey always thinks of the dog wagging its tail.

She patted her little face with her hands and began to sing after a while.

“@￥……#￥#@%……￥#……~”

The ethereal song instantly penetrated through the glass. Harvey felt an invisible sound wave coming on his face, which submerged his body and all his senses. Even his sense of smell seemed to hear a wonderful song. This is a feeling that Harvey has never experienced before, so he can't find an effective way to fight. The crisp electric current flows through his whole body. His whole heart trembles and he is willing to fall into nothingness. His reason collapses and pursues the song.

"No, it's more effective than I thought!" When he realized this, his reason gradually became numb, and all his vigilance naturally relaxed. He squeezed the back of his hand with the last trace of strength, but he could not feel the pain.

Too late to be shocked, Harvey stood up and approached the fish tank.

Beyond the influence of environment and personal factors, singing directly penetrates Harvey's spirit and even deeper soul, and becomes a forbidden fruit that ordinary people can't refuse.

In a daze, Harvey gradually understood the meaning of the lyrics.

"Come, our warrior

Please stop and listen to us

Here is the wine of your hometown

Please stop to rest and listen to our songs

Beautiful songs give you happiness and wisdom

With you safely sailing forward

·······”

Lily is singing happily with her hands together, which is different from her baby like babbling, and contains mysterious and powerful power.

Not long after, Harvey just got close to the bathtub, and the magic crystal he set on the table gave off a dim light, and then played Harvey's recorded interference music.

"The boundless horizon is my love

The flowers are blooming at the foot of the green mountains

What kind of rhythm is the most swing

What kind of singing is the most joyful

The winding river comes from the sky

Flowing to the sea

We are looking forward to the songs of clattering

Singing along the road is the most comfortable

If we want to sing, we must sing the best!

······”

Lily, the little sea monster, stops singing suspiciously. She looks at the magic crystal not far away and giggles. She has never heard such a strange song before. She waves her hands and pats her tail with the rhythm of the happy lyrics and dances awkwardly in the water.
