Everyone travels through the weird survival train. The train will travel through space and stop at some large and small platforms. Outside the platform are strange and terrifying copies. After the train arrives at the station, you can only complete the copy before you can continue to open the train (the stop period is the time when the copy is opened. If you stay in the train for more than a period of time, you will be swallowed by darkness). After completing the copy, you will have three days to rest on the train.
