"To be exact, the New World was created by me with my power. My purpose is to give you the ability to protect yourselves."
Jack nodded. Surprised as he was, he couldn't find a reason to retort.
Seeing that Jack didn't have any doubts, the old man was very happy and continued.
"The universe is very big. It has different kinds of space-time. They are independent and don't interfere with each other."
"But two spaces will be connected after some time."
"Your space will be connected to the New World in a year. I don't want you to lose too badly, so I build this game."
"Don't underestimate the New World. What you see now is only a small part. There're many unknown areas. You haven't been to those areas so far."
After saying that, the old man took a look at Jack to see how Jack would react.
"Since you want to save us, you can just step out when the space overlaps. Why do you do that?"
Jack asked with respect.
