At the wedding of the Lin family, a wealthy family in Haicheng, Su Yan, who has no car, no house and no job, became the most eye-catching presence. He got married according to his grandfather's last wish, but was mocked in public by his second uncle Lin Guodong and business rival Zhao Tiancheng for "eating soft rice". Even his newlywed wife Lin Wanqing only looked on with cold eyes. In the face of roars of laughter, Su Yan silently took out the miniature carving knife passed down by his grandfather - the seal character "Su" on the blade concealed the mystery of ancient weapon making, but the sentence "I rely on my craftsmanship to make a living" attracted even more unrestrained ridicule. Only Lin Wanqing secretly rescued Zhao Tiancheng on the pretext of "wedding props" when he was snatching the carving knife, leaving intriguing foreshadowing.
On the second day after the wedding, mother-in-law Zhou Mei threw the security uniform and said bluntly, "Don't just eat at home." Lin Guodong fanned the flames and said, "You can't even be a security guard. It's useless to keep it." However, Su Yan refused in a humble manner: "The craftsmanship I do is temporarily not needed by Lin, but I will never take wages that are not mine." When he accurately pointed out the problem that Lin Guodong was helpless in breaking beams and mortises and tenon joints in the old house, the expression of his second uncle, who had always despised him, suddenly changed.
This inconspicuous carving knife hides the inheritance of the Su family's century-old ancient weapon making; this "soft-earned son-in-law" who was ridiculed by the entire Internet is actually a top craftsman who can repair thousands of years of mortise and tenon joints and carve heirloom treasures. When Su Yan cuts through the glitz of the city with his carving knife and amazes everyone with his craftsmanship, those who once despised him will finally understand that the so-called soft rice is just the low profile of a strong man before he shows his edge; this carving knife can not only carve wood and stone, but also carve a period of counterattack from a son-in-law to a legend.
