There were five people who saved the students, three men and two women.
After they rescued Tu Dan and her group, they asked her whether there was fog in Hangzhou City. At that time, Tu Dan had just escaped from Hangzhou with her students and encountered the game; she was in a state of shock.
She didn't understand why these people were courting death, but still guided them. Meanwhile, she heard a fat man saying, "Hurry up, don't let others beat us to it!"
Another woman casually replied, "What's the rush? Everyone in the maze is probably dead. Who will compete with us..."
In the time it took for these exchanges, their vehicle had already driven off.
Tu Dan didn't take it to heart. She was focusing on how to seek refuge in Yangzhou, but never expected that there was a dense fog in Yangzhou, too, and the rescue ship hadn't arrived.
Later, Tu Dan and the students gradually calmed down.
