My Restaurant Specializes in Invasive Species

Yu Yang transmigrated into the body of an unlucky man.

The man was in his twenties, lazy and uneducated. After awakening low-level mental powers, he thought he was better than everyone else. He never went to work, only complained about his parents and looked down on his poor family, wishing he had been born to rich parents.

An accident bound him to a wish-granting System that could make any wish come true, as long as he paid the price.

The moment he got the System, he wished to become the child of a wealthy family.

The System granted his wish.

A few days later, a rich man came to his door and told him that he was his biological son. The hospital had mixed him up with another baby at birth.

The man was overjoyed. He immediately threw himself into the arms of his new parents, abandoned his poor ones, and happily went home with the rich man.

On the way, the System collected its price: the man got into a car accident. His head was badly injured, and he lost his mental powers.

When the rich man learned he had lost his mental powers and was no longer useful, he changed his attitude and cast him aside, ignoring him completely.

The man had become the child of a rich family, but the rich man had many children, and competition was fierce. After losing his mental powers, he became the worst of them. Not only did he fail to enjoy the luxurious life he had imagined, but the other children also bullied and framed him, making his life miserable.

The man was indignant and unwilling to accept his fate, so he made another wish to the System: he wanted to awaken high-level mental powers.

The System granted his wish.

One of the rich man's children tricked him into going to an underground laboratory, where he was locked up as a test subject. He underwent surgery at the same time as another test subject, and part of their brains was swapped.

A few months later, he did indeed awaken high-level mental powers, but his body rejected the procedure, causing him to suffer a mental breakdown.

This time, the price the System collected was money.

After being rescued from the laboratory, the man discovered that he had somehow acquired an enormous debt. Not only had the rich man taken back all the money he had given him, but the man also owed ten times that amount.

Now he had suffered not only a mental breakdown, but a psychological one as well. The things that mattered most to him were mental powers and money.

Losing his money was worse than dying.

Impatiently, the man made another wish, asking the System to cure his mental breakdown.

Once he was cured and had stable, high-level mental powers, he could trample all the rich man's other children underfoot.

The System granted his wish.

This time, the wish was fulfilled in an unusual way. In the man's interstellar world, curing his mental breakdown was impossible, so the System sent him to the merfolk world.

The merfolk world had many unusual fish, and eating them could heal mental powers.

This time, the System collected his lifespan as the price.

Having lost his mental powers and his money, the man's lifespan was the only thing he had left of value.

The System took ten years of his life.

If the man had simply healed his mental powers and returned to the interstellar world, he could still have lived for many years with his high-level abilities.

But when he saw the beautiful merfolk, he developed the wrong kind of desire and asked the System to help him control them.

Every time he controlled a merperson, their singing would bewitch him. Lost in his fantasies, the man had the System take more and more of his lifespan.

In the end, it was only natural that the man died to the merfolk's song.

That was when Yu Yang transmigrated into his body, taking over his identity and the mess he had left behind.

Yu Yang: "..." What a disastrous start.

In the interstellar world, the man was notorious for loving wealth and despising the poor, and was deeply in debt. In the merfolk world, he had used underhanded methods to control merfolk, making them all hate him. He was about to be executed.

The System asked Yu Yang, "Want to save yourself? Should I grant you a wish?"

"No!" Yu Yang firmly refused. "Making a wish would just make me die faster."

The man's fate was proof enough.

The System said, "Then how are you going to save yourself? The merfolk are about to execute you."

Yu Yang had his own way.

Before transmigrating, he had been a potion maker.

Yu Yang discovered that the merfolk here suffered from a strange disease. Many had rotting scales that fell off their tails, and it looked serious. If he could find a cure, the merfolk might let him go.

Yu Yang asked the System what caused the disease and discovered it was linked to invasive species.

In recent years, some foreign fish had appeared in these waters. They were not very aggressive, but bred rapidly. As their numbers grew, they created a swarm effect and released a toxin that made the merfolk sick.

Once he knew the cause, Yu Yang studied it for a while and soon concocted a medicine that could cure the merfolk.

After the merfolk recovered, they indeed put aside their grudge and let him go.

The invasive fish harmed the merfolk in their world, but in the interstellar world, they were extremely valuable. They could heal mental powers and were worth a fortune.

Using the System's ability to travel between worlds, Yu Yang brought the fish that were overpopulating the merfolk world back to the interstellar world. He opened a restaurant, serving uniquely flavored seafood dishes that drew in a huge crowd.

Yu Yang made a fortune in the interstellar world while solving the invasive-species problem in the merfolk world. His business flourished.

After being used over and over again, the System couldn't help trying to tempt him: Don't you want to make a wish?

Yu Yang: No.

The System: Don't you have any wishes at all?

Yu Yang: I do.

The System: Then why don't you make one? How can you resist?

Yu Yang: What's so hard to resist? I can even resist the merfolk's songs. Your wishes are traps.

The System said in surprise, "The merfolk's songs? You mean the courtship song the Merfolk King sings to you every night? So you can hear it! I thought you were deaf. And you can resist that?"

Yu Yang: "..."

The System: The Merfolk King's song isn't a trap. Why won't you accept him?

Yu Yang: There's no explaining things to a System like you...
