My Hotel Specializes in Invasive Species

Yu Yang traveled through time and lived in the body of an unlucky man. This man is in his twenties, uneducated and has no skills. He has awakened low-level spiritual power and feels that he is superior to others. He does not go to work all day long and only blames his parents. He despises his native family for being poor and wishes he was the child of a rich man. An accident bound him to a wish system that could grant any wish as long as he paid a price. As soon as he got the system, he immediately made a wish to the system, hoping that he would become the child of a rich man. The system fulfilled his wish. A few days later, a rich man came to his door and told him that he was his biological child and that the hospital had given him the wrong child with another child. He was so overjoyed that he immediately threw himself into the arms of his new parents, abandoned his poor parents, and happily went home with the rich man. On the way back, the system took a price and caused him to have a car accident. He was severely hit on the head and lost his mental power. The rich man knew that he had lost his mental strength and was no longer of use, so he changed his attitude towards him and put him aside without paying any attention to him. Although the man became the child of a rich man, the rich had many children and the competition was very fierce. After he lost his mental power, he became the worst one. Not only did he not live the prosperous and wealthy life he imagined, but he was excluded and framed by other children, making his life very difficult. The man was indignant and reluctantly made a wish to the system, hoping that he would awaken his advanced spiritual power. The system fulfilled his wish. The man was tricked into an underground research institute by a rich man's child, locked up and used as a test subject. He underwent surgery at the same time as another test subject and exchanged part of his brain. A few months later, he indeed awakened to advanced spiritual power, but a rejection reaction occurred, causing him to suffer a mental breakdown. The price the system charges this time is money. After the man was rescued from the research institute, he found that he had incurred a huge debt for no reason. Not only had all the money given to him by the rich man been taken away, but he also owed ten times the money. At this time, he not only suffered a mental breakdown, but also a psychological breakdown. The most important thing to him was his mental strength and money. Losing the money was worse than letting him die. The man couldn't wait and made a wish to the system again, asking the system to cure his mental breakdown. As long as he is cured and has stable high-level mental power, he will be able to trample all the other children of the rich under his feet. The system fulfilled his wish. The process of realizing the wish this time was quite special. In the interstellar world where the man lived, it was impossible to cure his mental breakdown, so the system sent him to the mermaid world. There are many special fish in the mermaid world. Just eating fish can heal your mental power. The price the system charges this time is his lifespan. A man loses his mental strength and money, and the only valuable thing left is his lifespan. The system took away ten years of his life. If this man honestly cures his spiritual power and returns to the interstellar world with advanced spiritual power, he can still live for many years. But when he saw the beautiful mermaid, he had inappropriate thoughts again and asked the system to control the mermaid for him. Every time he controls a mermaid, the mermaid will confuse him with songs. The man is immersed in his own fantasy, and his lifespan is taken away by the system time and time again. At the end, the man naturally died in the mermaid's song. Yu Yang traveled through time at this moment, taking over the man's identity and the mess he left behind. Yu Yang: "..." Tianbeng started. In the interstellar world, this man dislikes poverty and prefers wealth. He has a bad reputation and is burdened with huge debts. In the mermaid world, he uses means to control mermaids, is hostile to all mermaids, and is about to be executed. The system asked Yu Yang: "If you want to save yourself, do you want to make a wish?" "No!" Yu Yang firmly refused, "I wish I would die faster." Just look at what happened to that man. System: "Then how can you save yourself? The mermaid is going to execute you." Yu Yang has his own way. He was a pharmacist before he traveled through time. Yu Yang discovered that the mermaids here were suffering from a strange disease. Many of the mermaids' tail scales rotted and fell off, which looked very serious. As long as there was a way to cure them, these mermaids should be able to let him go. Yu Yang asked the system about the cause of the mermaid's illness and found that it was related to invasive species. In recent years, there have been more exotic fish in this sea area. These fish are not very aggressive, but they are extremely reproductive. When the number increases, they will have a group effect and release a toxin that will make the mermaids sick. Knowing the cause of the disease, Yu Yang studied for a while and quickly prepared a medicine to treat the mermaid. After the mermaid was cured, he let him go regardless of the past grudges. The invading fish in the mermaid world are harmful to mermaids, but in the interstellar world these fish are very precious, can heal spiritual power, and are priceless. Yu Yang used the system's ability to travel back to the interstellar world to bring the overflowing fish in the mermaid world, and opened a restaurant selling unique seafood dishes, attracting a large number of customers. While Yu Yang was making money in the interstellar world, he was solving species invasions in the mermaid world, and his business was booming. The system was repeatedly used for free, and he couldn't help but seduce him: Don't you want to make a wish? Yu Yang: I don't want to. System: You don't have any wishes? Yu Yang: I do. System: Then why don't you make a wish? How can you bear it? Yu Yang: If you can't help it, I can even hold back the mermaid's singing. Your wish is a trap. The system was surprised and said: Mermaid's singing? Are you talking about the mating song that the Mermaid King sings to you every night? It turns out you heard it. I thought you were deaf, but I couldn't bear it. Yu Yang:...... System: The Mermaid King's singing is not a trap. Why don't you agree? Yu Yang: I can't explain the system to you... The pharmacist with a particularly strong will is attacked by the Mermaid King who responds to every request. 1V1he 2025.12.29 Purpose: Protecting the environment is everyone's responsibility
