As the last remaining member of the dragon clan, Li Hanyi has only one annual KPI: survive and find the enemy who exterminated the clan. The best disguise is to become a complete waste. So, he worked hard to become the Lin family's son-in-law. In the past ten years, his son-in-law's resume was perfect: he could do all the housework, wash, cook and mop the floor, he was proficient in everything; he was emotionally stable, despite the cynicism of his sister-in-law and the difficulties made by his mother-in-law, he remained firm and even managed to serve with a smile; he had a low sense of presence and was a famous "soft rice man" in the upper circles of Jiangcheng, and was the most difficult "stain" of the Lin family. No one knew that when night fell - Li Hanyi, who had been fighting with fish scales in the kitchen during the day, would practice the most tyrannical ancient martial arts of the Dragon Clan with his bare hands in the courtyard, and the strong wind could tear the air. Li Hanyi, who was scolded by his mother-in-law during the day, would sneak into forbidden areas and trace the whereabouts of the Dragon Clan's treasure "Dragon Bone Diagram" with the help of vague memories in his bloodline. He thought that his story of the transformation of his son-in-law would last until the finale. Until the Lin family's building was about to collapse overnight, and enemies came to the door, threatening to slaughter the entire Lin family. His cheap wife was forced into a desperate situation and stood in front of him: "He is just an ordinary person, come at me!" Li Hanyi: ... Okay, stop pretending, let's show off. When he stood up in the ruins and defeated the powerful enemy with one punch, with the dragon-shaped tattoo looming on his back, everyone was stunned. What made him even more dumbfounded was that he found that his father-in-law, who usually loved to play bracelets and talk about health care, was wearing a ring on his hand.
