Resolutely Staying a Background Character

Xin Shansi transmigrated into a book... And became a madwoman. In the story, the madwoman was young but possessed peerless inner strength, so she was kept locked up. Her only role was to give the heroine sixty years' worth of inner strength when the heroine was gravely wounded. Once she gave away her inner strength, the madwoman died. She wasn't quite a supporting character or even cannon fodder, just a bit player at best. When Xin Shansi arrived, the number-one female antagonist was egging her on to steal a bridegroom. Whose bridegroom? The one the Valley Master of Hongdai Valley had set her sights on. Xin Shansi jumped up eagerly. "Quick... unlock my chains." As soon as they were off, she bolted, vowing to get as far away as possible from the number-one female antagonist, who was clearly insane. But... can someone tell her why she got caught up in a bride-stealing plot when there wasn't one in the book? Not only did she get caught up in it, but through a series of strange coincidences, she ended up with someone... It's hard to explain. Then came an even bigger shock: she was pregnant... And that wasn't all... Wasn't that man just a pretty boy? How did he suddenly turn out to be Li Shang of the Hundred Herbs Hall? In the book, Li Shang was almost demonic in his intelligence. He looked peerlessly handsome, noble, and ethereal, but in truth he was willful, cold-hearted, petty, and vindictive. He was the one who killed his own master. It's over. Xin Shansi held her huge belly with both hands and stared down the long, empty road ahead, already picturing what the King of Hell looked like. A seemingly foolish but actually wise heroine & a male lead who is almost demonic in his intelligence A few things to know before reading: 1. The male lead is not the original male lead. 2. Both the heroine and the male lead are seriously ill. When they first meet, neither mistreats the other; they each save the other once. 3. The society in this story is fictional, so please be cautious about historical accuracy. 4. The characters' values belong to them and don't represent the author's own. Feel free to comment on the characters, but please don't attack the author personally. Thank you. Three bows!!! Theme: Be kind.
