Thanks for the chapter!
I hit it when things get cut off when it starts getting interesting or can't tell what happened in between. So is Ye Chiang still a virgin or did MC indulge her and slept with her (maybe multiple times?) Although seems unlikely considering he's still wearing the top and bottom of pajamas?/clothing and she's wearing a negligee(?) unless author into strongly hinting without actually showing anything like breasts. In any case, assuming the guide is true and a male cultivating without parting with little Johnny would explode why hasn't MC exploded from all the cultivating he's doing? Is it because his cultivation techniques were originally thought up and refined by men so works in both worlds or his his body still retaining traits from his original world allowing cultivation while all the other men are out of luck? For Tang's sake hope he makes a breakthrough on the medicine that actually does what he wants as opposed to being poisonous for some reason. As for Chiang I hope MC has a photographic memory and is able to memorize the book to look over later as she'll get in a huge amount of trouble once the book is discovered missing and/or was shown to him. While it's good she's willing to support and help him, needs to consider possible consequences of her actions more as this might get her disowned or used by that murderous Aunt as a weakness to exploit to ruin both her and her mother.
@Kamelpov Arthur probably not be a girl. Even if was conceived Morgan Le Fay likely became head of the family, hopefully with less emotional baggage, as society was Matriarchal rather than Patriarchal. Or one of his sisters taking the main lead. That and their mother Igraine would have been the one charging forth into battle, his father Uther unable to fight against other women so likely stayed home taking care of the castle or was the one pursued by Igraine instead of pursuing her.
