Ten years ago, there was a river of blood in the East Palace. Zhou Yan, the orphan of the former prince, escaped by chance and opened a tea shop in a small town in the south of the Yangtze River incognito, just to live a stable life. Until that day, Su Jinshu, the most domineering lady in the capital, smashed his sign, carried her luggage and moved into the backyard, and said confidently: "The tea you made is acceptable, I will stay here for three months." Zhou Yan just wanted to send the giant Buddha away, but he didn't know that she brought not only trouble, but also the aftermath of the bloody storm ten years ago. When the officers and soldiers who searched the house surrounded the tea shop and Su Jinshu stood in front of him, Zhou Yan sighed, wiped off the tea stains on his hands, and smiled at the leader: "Commander Li, I haven't seen you in ten years. Do you still recognize the old owner of your sword?"
