On a rainy night during the Qingming Festival, the tombkeeper Chen Shoucai received a call in front of his ancestral grave - the caller ID read: Chen Changsheng. That was his ancestor who had been sleeping for hundreds of years. Someone was sitting in the coffin and talking to him on an old-fashioned mobile phone. "I just took a nap." Ancestor said calmly. The next day, Chen Changsheng stepped into the bank and asked to withdraw 300,000 taels of silver deposited during the Wanli period, which is equivalent to 120 million today. No ID card, no bankbook. The president sneered: "There are no rules." Ancestor slapped the counter with his palm, and the granite cracked into spiderweb-like lines: "Rules are for people, not for bullying." An hour later, the bank called the police, but the police were silent when they arrived - Chen Changsheng took out a yellowed imperial edict and stamped it with the Wanli Jade Seal. The president collapsed on the spot. But a bigger storm lies behind: the land where the ancestral grave is located has been secretly purchased by a real estate developer, and the excavator is roaring towards the cemetery. A battle for heritage spanning four hundred years is about to explode.
