I'm Pregnant, and It's Yours

"Young Master, why are we going to the Divine Physician Valley? You're fine, aren't you?" "Call me big brother!" Chen Xin said, looking a little annoyed. "And who says I'm fine? Didn't that quack say it? I'm pregnant. I've never heard of a man giving birth, so for the sake of my life, I think I should go to the Divine Physician Valley and ask." "You're really pregnant? No way!" "Why not? I went to a lot of trouble to follow the book and make that potion that can change one's constitution!" Chen Xin said proudly. "Then... who's the child's father?" Sishu couldn't help asking the most important question. "Huh? I don't know either." "What!?" "Yeah. I was going to have you try it, but then a flower thief showed up that night. Everything went black, and I don't remember a thing."
