This is a world abandoned by the Beast God. Female beastfolk have low fertility, and pregnancy is difficult.
To save this world, you must give birth to young beasts here. Every birth brings a reward, and you can go home only after you have given birth to one hundred healthy babies.
Hai Lan: ? All right, I agree.
System: I know this is hard for you, but... what? You agreed? Did you hear me? Not one, a hundred!
Hai Lan: What's a hundred? I can lay a thousand eggs at once.
System: ?? Wait, what species are you... a sea... a seahorse?
Hai Lan: Yep! I can provide the eggs. You'll have to handle the pregnancy and birth yourselves. What do you mean there are males without brood pouches?
You made it sound so pitiful, saying you wanted offspring, but now you won't give birth yourselves? Liars! You don't really want babies at all!
You're useless. What does that have to do with me? I gave you precious eggs, so I still deserve my reward!
Theme: Babies are the future!
