The heroine Alai is a somewhat naive modern woman with a strong curiosity. Whenever you encounter excitement in life, just join in. One time, I accidentally joined in the fun and followed a group of people who were preparing to travel through time. I wanted to go on a three-day trip to enjoy the prosperous Tang Dynasty. Not wanting to encounter the legendary "Earth Dragon Turns Around", a group of them came to the early Ming Dynasty, which was still a bit turbulent hundreds of years later. And the turnaround time becomes three years before we have the chance. Then he was taken to the Yamen for an unexplained cell phone camera incident. Because they had no identity documents, they were all sent to prison and eventually turned into slaves. This is a poignant and hilarious journey for modern people in ancient times. In the end, it is better to linger in the wealth of ancient times or seize the opportunity to return to modern times. See how they choose.
