Zhu Lin, who grew up in an orphanage, has a withdrawn personality, a cold face and a warm heart. He has had a strange ability since he was a child - he can see the "value fluctuation" curve of anything he touches in his mind. As an adult, Zhu Lin worked as an apprentice in a gold shop in the city. One day, the richest man in the city, the Zhu family, suddenly came to his door and claimed that he was his biological son who had been transferred twenty years ago, and that Zhu Wan, the "daughter" who had been raised by the Zhu family for more than ten years, was a fake daughter. The Zhu family asked him to "return in a low profile" and complete a "family recognition show" with the fake daughter to protect the family's face. However, Zhu Lin discovered that the Zhu family didn't care about him at all, and just wanted to use him to appease the fake daughter with congenital heart disease and replace her with a matching heart donor. The so-called family love is just a scam of moral kidnapping. Zhu Lin watched with cold eyes, until the relatives of the Zhu family took turns to fight, using "blood", "filial piety" and "overall situation" to force him to sign to donate marrow and kidney, he smiled. He picked up the ancestral copper coin that he had carried with him since childhood and said to all the Zhu family members: "If you want to talk about blood and family ties, then I will use this copper coin to teach you what the Golden Rule is."
