The Frail Prince's Little Mongrel

Lin Yichen read a novel whose protagonist was a prince who had been driven from the palace by palace intrigue and raised among the common people from a young age. The prince was frail, liable to collapse at the slightest breeze. It was bad enough that people bullied him, but even the dog he raised got bullied by other dogs. Of course, as the protagonist, he was bound to have a halo. His weakness was a disguise, while his ruthlessness was his true nature. In the end, he still made it back to the palace and rose to power. But what does that have to do with me? Lin Yichen, who had accidentally transmigrated into a book, sat on a hilltop, stared at his own paws, and fell into despair. Why could everyone else who transmigrated into a book become the protagonist, the villain, or a disposable extra, while I have to become a dog? Is my purpose in life to eat shit? No! I refuse! Just then, a frail, handsome man walked over and patted his head. "Gold Ingot." Lin Yichen: "...?!" What? That's my name? He's the protagonist? And I'm the dog who gets bullied??? Lin Yichen refused to accept his fate. He picked a fight with Dahei, the village bully, and won through cleverness, laying the foundation for crushing every other dog with his intelligence. It wasn't exactly a fair win, but it felt so good! He decided that his next step would be to beg for affection from his master. A dog who knows how to act cute has the best life, and he was going to the palace! Lin Yichen: I'm going to the palace to eat and drink like a king. Yan Huaiting: You're going to the palace to be my empress. From the love interest's point of view: Before he was reborn, Yan Huaiting was gloomy and obsessive, unable to trust anyone, including the godlike person who could always conjure silver for him to spend. That person couldn't farm, write essays, or fight. He often talked to himself while staring into thin air, and his behavior was strange and mysterious. But he was kind, and granted every one of Yan Huaiting's requests. Eventually, Yan Huaiting locked him up, his eyes bloodshot as he said, "You're mine. Don't even think about going anywhere. You'll stay by my side for the rest of your life!" In the end, that person was driven away by him, leaving behind one message: Let's keep in touch by message in a bottle! Yan Huaiting: ...What does that mean? Later, the emperor, who had lived out his days alone but become very good at making messages in bottles, was reborn. This time, he decided to be gentler with his little immortal, gentler still. But after searching every hilltop, he was horrified to discover that the person was nowhere to be found. The person who blushed whenever he saw Yan Huaiting and gave him anything he asked for had vanished from the world. Only the little yellow dog that person had adopted remained. Distraught, Yan Huaiting picked up the dog and decided to raise it well, only to discover... His dog was cunning, becoming king of the dogs overnight. His dog was a smooth operator, leading the whole village to prosperity. His dog had a special talent: it could even imitate the little immortal's voice. Yan Huaiting: ...?!
