Because none of those doors had opened, only the door at the position of the first car had opened.
"Mr. Mu, are you summoning the Bloody Train to take action?" the train conductor approached with brisk steps.
"Not yet, there has been a slight change in plans, just wait for my message."
"As for now, I would like you to take me to the real world," said Mu Rufeng.
"The real world? No problem, but it might take some time," the train conductor replied.
"Some time? How long? When I summon in the real world, doesn't it always arrive within a few minutes?" Mu Rufeng asked.
"Mr. Mu, this is different. Before, you were summoning in the real world, where the power of the Black Gold Card directly broke through the rule barrier."
"But now you are going from the Mysterious World to the real world, and it's different. We need a bit of time to travel to a place where the rule barrier is weak."
"It will take about half an hour to get there," the train conductor said.
