What a curious mortal. "It's no trouble at all." In fact, he likes the troublemakers. He's pretty sure he has seen him on the train, but what's he doing on the platform? Did the other one left? He has to pester his team leader, Lan Wangji later. He gives him a few moments and space to orient himself as he examines the sights and sounds, but this is only the platform.

"I do not know. Its source is a mystery to me and the length of the journey in days and months is unknown. All I know is the train pulls people from different worlds, and then it travels through the void, through space to other worlds in different dimensions. Its mission is to save worlds and the train is asking us to use our powers for that purpose."

Sensing his distress, "I recommend that you don't panic. You do have family members and friends here. One being is Lan Wangji. I think he's onboard, and he can answer your questions if you can go to meet him."
