Answering space is a very common thing in the multiverse. It can broadcast images of parallel worlds or the future to multiple worlds.
But there are always some weird things in the answering room, such as...
Otto: "Karen, the hand you should hold is no longer mine."
Xi'er: "The rules of victory have been determined!"
Dr. Rhodes Island: "The sky is calling, the earth is calling, and people are calling, calling me to defeat evil! I am the partner of justice - Kono Armor Hero W!"
(Note: This W is the W of Arknights)
Hey, you are the only one who can be called my friend. So, fight with me, Zijun.
Nanami Chiaki: Watch me clear the level with one life!
Emperor of the East Sea: Senior Mi Yu, why are you just standing there watching? Are you really a traitor?
……
Audiences from all over the world watched these scenes with puzzled expressions on their faces.
What the hell is this?
