The world is broken, my Valkyrie is doubled

Wang Chen accidentally came to the world of collapse, but his system was not very reliable. He had to do everything himself and couldn't help complaining: Tongbao, what use do I have for you?
System: Host, why don’t you first imagine the most beautiful moment you can create in this world?
Wang Chen began to fantasize, fantasizing about dominating destiny, fantasizing about changing the tragedy and reviving the good energy, and of course especially fantasizing about conquering one Valkyrie after another and becoming a loving family with them.
System: Very good, remember this feeling between you and the Valkyries, the happiest moment, the warmest moment, the most gentle moment. And now, host, you only need to do one thing, multiply your best feeling just now by two!
Wang Chen: What!? Times two!?
Under the influence of the system, Kiana, Raiden Mei, Bronya and... one after another, the Valkyries who once had full favorability in the game also appeared in this world. What kind of sparks will the Valkyries on the ship and the Valkyries in this world create?
Wang Chen: Help... Help! I can’t take it anymore, I really can’t take it anymore!!
But what awaits Wang Chen is probably a road of no return where he will never be able to stand up again (laughs)
