Lingering Sound on Track

When he woke up one day, Li Zhen found himself lying on a strange and mysterious train. The scenery outside the train was always strange, familiar and strange. It was only through the strange radio sounds and the whispers of the crowd that they learned that everyone was a passenger who was forcibly pulled into the carriage and must participate in an endless trial of survival. In this train that doesn't know when it will end, it seems that only your own choices can determine the way forward. Strange travelers meet one after another. Some carry a heavy past and move forward in silence, while others seem gentle and friendly at first sight and treat others calmly. However, no matter what, as the train pulls, the test of human nature begins. In the gap between good and evil, everyone has to face the truest self in their hearts.
