Grinding for Cards in an Infinite Game

I woke up in a completely unfamiliar world. And I had to complete all kinds of games. If I was killed in a game, I would cease to exist in reality. Waaaah, I want to go home. But the game supervisor said that each round let you collect cards, and gathering enough cards could grant a wish within the scope of the cards. After completing the first game, Xu Wenyue got a card. Damn! What an unbelievably gorgeous face. I’m totally smitten. Game Supervisor: This is a character card, dear. Collect all sixteen and you can exchange them for the character pictured on it. Xu Wenyue had only one thought left: I want him!
