banquet is to be held 7 days after birth now it is 2 days left so it is reasonable to say it took 3 to 4 days refining a herb as she can't refine it as soon as she gave birth right? She gotta take care of her kid as well.
it's an amazing book with a wide scope of development. the character are very well designed I especially like the childhood part. it says 7 chapter per all but update isn't stable
