The male supporting character was actually myself.

[Mission: Help Lian Yunshang stir up the sea and create waves so that Wen Menglong can come out of the cabin. Reward: One-time use D-grade item x1]

Almost at the same time as entering the mission world, the main system mission was released.

At the same time, he had already received the current plot point in his mind.

The female protagonist, Lian Yunshang, has just swallowed a clam spirit's elixir, increasing her magical power by five hundred years. She can now freely transform her fish tail into legs. At this moment, she is asking the hidden version of the sea god, with whom she grew up, to help her stir up the sea and create waves so that the passengers on the merchant ship on the sea can get out of their cabins.

"Brother Chen, please help me!"

Lian Yunshang has been close friends with Jiang Chen, an orphan who has no parents, since childhood.

Because he looks more like a human, he is always ostracized by his peers in the mermaid world. Only Lian Yunshang, who is not skilled in magic and has weak magic, often stays by his side. She knows that as long as she acts cute, he will definitely help her.

Moreover, Jiang Chen was born with exceptional talent and profound magical power. He could stir up the seawater and create huge waves without capsizing the ship, something that would be difficult for me to do but easy for him.

Seeing that Jiang Chen did not respond to her request immediately as usual, Lian Yunshang used her best skill, shaking her beautiful fishtail and pleading innocently, "Brother Chen, please!"

“Alright then, I’ll only help you this once.” Jiang Chen’s lips curled up slightly as he explained earnestly, “As a member of the merfolk, it is not allowed to use one’s own magic to interfere in the human world. Since you want to repay this debt of gratitude, let me remind you first—don’t interfere too much, just a little is enough.”

Lian Yunshang happily took his arm and shook it, saying, "I know. As expected, Brother Chen is still the best to me!"

"You really think so?"

Lian Yunshang was somewhat puzzled by the other party's sudden question.

I always felt that Brother Chen was different from usual. It was probably because he was ostracized by his peers when he was young. He was mostly silent and rarely spoke. It was rare for him to speak up like he did today.

However, since she needed his help, she smiled sweetly and nodded, saying, "Yes, yes, Brother Chen is the best person to me in the world!"

Jiang Chen glanced at her coldly, "Your grandfather raised you from childhood to adulthood, yet in your heart, he doesn't even value me as much as he occasionally helps you. Yunshang, don't talk like that in the future; it's easy to cause misunderstandings, and your grandfather would definitely be very sad if he knew you thought that way."

Lian Yunshang: ⊙﹏⊙∥

I... I was just saying it casually, I wasn't serious...

Choked by her words, she pouted and remained silent, clearly displeased that her usually doting and protective brother Chen had suddenly become somewhat cold and unapproachable.

The little white cat stuck out its tongue and made a face at her, "Hehehe~ My host would never be your simp! You got roasted, didn't you? Serves you right! Who told you to always be so ambiguous with the original owner, making her mistakenly think she had a chance?"

So, after I helped you find your benefactor's reincarnation, you immediately offered yourself to Wen Menglong and slept with him, you green tea bitch!

Jiang Chen used his magic to swim towards the sea, and Lian Yunshang hurriedly followed, summoning her best friend Liu Ying to come and help.

The three of them emerged from the water and used the waves to conceal themselves.

A merchant ship was slowly approaching from a distance on the sea, heading towards a beautiful island in the distance, where birds sang and flowers bloomed, and pavilions and towers were hidden.

"Yunshang, how did you know that the reincarnation of your benefactor would appear in this sea area?" Liuying, a mermaid with a silver fish tail, was sweet, charming, and lively. She looked around curiously and asked.

A smug look appeared on Lian Yunshang's pretty face. "I went to see the Spirit Master to have my fortune told. She said my savior has been reincarnated six times and will be passing through this sea area soon. If I want to repay her kindness, this is my only chance. That's why I..."

She didn't have the heart to say it in front of Jiang Chen, who had just criticized her.

Because his cultivation was too slow and his magical power was too weak, he saw that the opportunity to repay his debt of gratitude was about to pass in the blink of an eye. In order to fulfill his wish, he inquired everywhere and learned that the clam spirit had obtained the elixir, so he stole and swallowed it.

And so, with an extra 500 years of magical power, he could instantly transform his fish tail into legs, making it easier to reach the land and repay his benefactor after finding him.

The merchant ship was getting closer and closer, and with their excellent eyesight, they could already see the people standing on the deck.

Pointing at a round, chubby man, Liu Ying joked, "Look how prosperous that person is! If he were your benefactor reincarnated, how would you repay his kindness?"

Lian Yunshang glanced at the fat man who was clearly dressed as a merchant, pursed her lips, and replied, "If it's him, I'll use my magic to help his business prosper and ensure his lifelong wealth and honor!"

"What if it were that skinny boatman?"

She glanced at the dark-skinned, thin ship's servants who were cleaning the deck and casually replied, "Then I'll use my magic to ensure his safety and give him a large sum of money. Whether he becomes a captain or goes back to do business, he won't have to work so hard anymore."

Upon hearing this, Liu Ying felt somewhat relieved. This level of gratitude was certainly acceptable, and it wouldn't cause a disaster by recklessly using magic to disrupt the balance of the human world.

In this way, he could confidently fulfill his promise to help Yunshang.

Chapter Three: Just Ordinary Friends

"Yunshang, you always say you want to repay kindness, but what kind of kindness is it?"

Liu Ying looked around curiously and asked, "Since you've already reincarnated six times, that must have been several hundred years ago... Could it be something that happened when you drank the elixir during your coming-of-age ceremony and came to the human world?"

Lian Yunshang blushed and lowered her voice, saying somewhat vaguely, "I can only let you, Brother Chen, and Ling Po know about this. Don't tell anyone else! Actually, it was during my coming-of-age ceremony that I... I got caught in a fishing net and almost lost my life. A little boy saved me."

A drop of water in need should be repaid with a spring of water, let alone a life-saving favor.

"If I don't repay this kindness, I'll always feel some lingering regret. The best way to ensure a long-term solution is to sever ties with the human world as soon as possible."

Liu Ying couldn't help but sigh, "Yunshang is indeed kind-hearted and beautiful. She's grateful for someone's small act of kindness that saved her life, and she'll remember it for centuries. Don't worry, I will definitely help you repay your kindness!"

"Tch~" The fluffy ball perched on its host's shoulder and scoffed, "If you hadn't been so playful and violated the family rules by lingering on the sea and flirting with little boys, they wouldn't have lost their lives for you. You broke the rules and caused someone's death, and you're just making a big deal out of it. Are you worried that your friends will ruin your image if they find out you were wrong first?"

"Host, you must stand firm on your side!"

Jiang Chen patted its head subtly to reassure it, then looked at the approaching merchant ship and whispered, "I'm about to begin. You only have one chance, so make the most of it."

"Thank you, Brother Chen!" Lian Yunshang was eager to try.

Concealing his form with magic, Jiang Chen floated on the sea and waved his right hand. Under the calm, deep blue sea, undercurrents surged and soon waves rose on the surface.

"Guests, we've arrived at Pomegranate Flower Island!" a servant dressed in a short shirt on the boat called out.

Many people leaned out to look when they heard the noise, and the number of people on the deck increased.

Jiang Chen continued to stir the seawater, causing the entire ship to rock violently as the waves surged.

"Oh dear, why are the waves so big all of a sudden?"

"There's no wind at all?"

"Boatman, is this boat safe enough?"

…………

The sudden violent shaking startled the passengers. Wen Menglong, who was enjoying the scenery in his cabin, almost lost his balance and fell to the ground. Seeing that everyone else rushed out to check the situation, he also got up and stumbled out.

"Host, do you need me to get a prop to help block the protagonist?"

Seeing this, the little white cat suddenly had a flash of inspiration and excitedly said, "As long as the female lead can't see the male lead, she can't 'fall in love at first sight,' right? If they miss this encounter, they'll never cross paths again, and this way, the revenge can be perfectly avoided!"

Jiang Chen smiled faintly and replied softly, "I don't need any props; I can do it with my magic."

In fact, the female lead would notice the abnormal fluctuations in magical power. To be on the safe side, he had already sent out soul artifacts to surround Wen Menglong before casting the spell to stir up the seawater.

Now, not only the female lead, Lian Yunshang, but even the other panicked tourists didn't notice that someone was missing.

"Crash! Boom!"

A giant wave lifted the merchant ship and crashed headlong into Lian Yunshang, slamming her into the water without any warning.

Lian Yunshang: ...

What's wrong with Brother Chen? The waves are too big!

Fireflies: (。oˇ?ˇo。)

What's wrong with Yunshang? As a mermaid, she can't even avoid this little storm? Is it because her magic power is weak?

The moment the waves slammed Lian Yunshang into the water, Wen Menglong, who had been forcibly made invisible, happened to lean out and look down. By the time she regained her footing and floated up from the sea, the other party had already blended into the crowd.

The little white cat promptly reminded me that the task was complete.

While floating in the water, Lian Yunshang took the opportunity to quickly look at the people on the deck. At first glance, she saw that they were all ordinary-looking people, and she couldn't help but feel disappointed.

"Don't just stand there staring. You have to figure out what the other person looked like several lifetimes ago to know if they are your savior."

Seeing her lack of interest, Liu Ying hurriedly urged, "It will take a long time to calculate with so many people. Brother Chen, you can't stir up the waves for too long, otherwise the aftershocks will be too big and affect other passing ships. That would be considered abusing your magic to interfere with the human world, and you'll be punished if the clan leader finds out!"

"Okay, okay, I got it, I'll start calculating now!"

Pressed relentlessly, Lian Yunshang had no choice but to select a young man who looked reasonably pleasing to the eye. She used her magic to instantly see that he had been a scholar in his previous life, a traveling merchant in his life before that, and so on, but she couldn't find any familiar figures even after seeing his previous six lives.

Lian Yunshang looked at all the handsome young men on the ship, but even after the merchant ship had sailed away smoothly, she still couldn't find the reincarnation of the little boy.

"It seems they're not on this ship." She sighed, watching the ship recede into the distance. "Let's wait a bit longer; maybe they're on another ship."

The firefly, its fish tail swaying idly, swam back and forth in the water and asked, "What exactly did the Spirit Master say? Can she be sure which boat she's on?"

"I can't be sure. She just said that I could meet her on any ship passing through the nearby waters in the next couple of days. She said the waves would help me, and that my savior would be reincarnated as a sixteen or seventeen-year-old boy. But I've already counted the ages of all the people on the ship who fit the description, and none of them are my savior reincarnated."

"Then we'll just have to wait a bit longer." Liu Ying waved her hand, "Brother Chen, come down and rest for a bit. I wonder when the second boat will arrive."

Jiang Chen whispered to the little white cat to follow Wen Menglong just in case, then fell into the water and said briefly in his usual slightly cold tone, "You must obey the will of Heaven. Since the Spirit Granny said that the waves will help you, you naturally don't need my help."

"Brother Chen is right!"

Liu Ying's eyes lit up with joy as she said, "What the Spirit Granny means is—if the ship carrying the reincarnation of your savior comes, the waves will naturally surge."

The sea was calm when that boat passed by; it was only because Brother Chen stirred the water that waves were created. How can we forcefully interfere with matters of fate using magic? So let's wait patiently.”

"That makes sense." Lian Yunshang didn't suspect anything and continued to immerse herself in the water, hoping that her benefactor would be reincarnated as a handsome young nobleman, so that she would be more interested in repaying his kindness!

Jiang Chen naturally didn't have time to waste with her, so he made an excuse and escaped by water.

Lian Yunshang watched his figure disappear into the deep blue sea, pouted and frowned slightly, and said, "Don't you think Brother Chen seems a little cold today?"

"He's been like this since he was a child, and he hasn't changed much in hundreds of years." Liu Ying swayed her fishtail to indicate that she hadn't noticed.

"No, Brother Chen is always so responsive and caring." A hint of displeasure appeared on Lian Yunshang's face, and her voice became much more somber. "I don't know what's wrong with him today..."

Liu Ying playfully rolled her eyes and teased, "That's because he likes you! Anyway, Brother Chen is never that nice to anyone else."

If that's the case, I think he likes you, so he's resisting your insistence on finding your benefactor's reincarnation to repay the debt—simply put, he's jealous!

On second thought, she realized her friend made a lot of sense. Lian Yunshang blushed slightly, sank into the water, flicked her fishtail, and said coquettishly, "Don't talk nonsense. Jiang Chen and I are just ordinary friends."

Chapter Four: The Test

"Hmm, actually I think Brother Chen is pretty good. Although he didn't look much like a mermaid when he was little, he has great magical powers, and his face is extremely handsome with a cool and aloof temperament. He's also so good to you, don't be ungrateful!"

"Oh, stop talking! It looks like another small boat is coming this way. Let's get down to business!"

Two charming and adorable mermaids swam around in the water, playing and chatting. Jiang Chen, however, turned and swam from the deep sea towards the island. At the same time, Wen Menglong, whose invisibility had been removed by the soul weapon, sat back in the cabin, looking at the scenery in the distance with longing. The little white cat sat on his shoulder, playing with its fluffy tail in boredom.

Liuhua Island is a great overseas island for spring outings and leisure travel.

With a small population and a mountain temple nestled amidst blooming wildflowers, it's a wonderful place that attracts many tourists throughout the year.

The Qingming Festival is a rare time when young women who usually stay indoors can freely go out to enjoy the spring scenery. In addition, Liuhua Island is famous for its beautiful scenery and its temples and deities that are said to be very efficacious, attracting many tourists every day.
