Going to stick to basics or there'll be nothing but Great Walls of text:
-at one point, Jiuling called in to cure her royal younger brother. She gets a pep-talk of sorts from Zhu Zan, who gets surprise-hugged. Treatment is successful. She also tries to dig up something her master left her, but is interrupted by Lu Yunqi who tries to choke her again. She seems to have passed on something to the old tutor she and her sister had.
-annoying uppity royal doctors getting on her case along with Lu Yunqi and his Jinyiwei. Jiuling gets sent outside the city to deal with the raging pox epidemic. Zhu Zan and his bros are worried and Zhu Zan loiters around her despite himself. It looks like the epidemic was caused by Lu Yunqi to corner Jiuling into solving it, because of course the Emperor would set her on this task since she's famous as a godly doctor. And the pox is technically incurable. Zhu Zan finds Lu Yunqi, confronts him, and punches him in the face. I liked that part a lot. XD
-Jiuling's 'solution' is more like prevention. The lives of those already who have it are up to fate, but she can use inoculation for the rest. I think she's using cowpox. Ugh, I think Lu Yunqi is starting to cotton onto Jiuling's personality and is sticking around... Jiuling feels nothing but disgust for him though. Lu Yunqi's idea of 'testing' is brutal, he captures people and brings them to Jiuling. She and her fellow doctors (not the royal ones) refuse because it's immoral -- they test it on themselves. And when they need kids for testing (since kids get it most easily), Zhu Zan brings kids who are on Imperial death row (because of their family) who voluntarily choose to try this out. If they live, the Emperor agrees to pardon them. Plus, you get the feeling that Zhu Zan trusts Jiuling to do right.
-news spreads across the country. Yangcheng and Runan people believe her of course lol, they come running to the Capital for the inoculation right away. Others are skeptical. After Imperial family gets to testing it out and proclaiming it good, other people come.
-WTF LU YUNQI. He suddenly decorates her place in red and announces he's found her fit to be his concubine. I hope Zhu Zan punches him again. Jiuling tells her people to just tear everything down and throw it out; her reputation is so strong right now that even Lu Yunqi shouldn't be able to force her. Plus there's still the Fang family's Imperial Edict.
-WTFFFFF OMG LU YUNQI IS SO CRAZY. HE STILL WANTS TO GO AFTER JIULING.
-public opinion is that Lu Yunqi is bullying Jiuling.
-Ning Yunzhao is top scorer for civil examinations. O.O
-YESSSS ZHU ZAN IS BACK TO PICK A FIGHT WITH LU YUNQI. GO GO ML~ Then Ning Yunzhao arrives on the scene. He hasn't heard about this Lu Yunqi business because he was busy with examinations. He teams up with Zhu Zan in a sense lol. He tells everyone that Lu Yunqi's deal is impossible because Jiuling's his fiancee. Later when Zhu Zan's in a private conversation with Jiuling, in a snit, we learn that this tsundere would have said Jiuling was his fiancee if Yunzhao hadn't said it first. Then Yunzhao later drops by and says it's technically fake too, and he's doing it to repay her. Jiuling says things will be squared between them with this. Back in Yangcheng, Ning family is going nuts lol, they don't get it.
-Zhu Zan is unhappy and drinking with his bros. Don't worry Zhu Zan, she likes you best. Later we see that Yunqi's all beaten up when coming home. Apparently it's Zhu Zan's work. <3
-hmm, Jinyiwei's rampant with reason. Apparently the Emperor allows them to because he needs Lu Yunqi... maybe this guy's the only support propping him up. Plus Jiuling asks Zhu Zan a curious question on why he's so good to the Emperor. Those things are probably related but I guess we'll see.
-OMGG NUUUUU. Lu Yunqi tries to corner/embarrass/ruin Jiuling again. Zhu Zan saves her but is implicated big time and given into hands of Jinyiwei and tortured. Jiuling goes off to save him while winning the admiration of his bros. This episode made me really hate Lu Yunqi and super admire Zhu Zan. Also Jiuling's bedside manner is hilariously ruthless lol.
-Jiuling leaves the capital. It was part of the agreement for getting to Zhu Zan she made with Lu Yunqi (that asshole). Fang Jinxiu's staying at the Capital and holding down the fort. Of course, Lu Yunqi means to grab her as she's leaving, but Zhu Zan has also made a move along with his bros.
-Jiuling's master's secret book is actually a book of war. Map, tactics & formations, weapons, etc. So he meant it when he said he wasn't a doctor. though there are some medical bits in there too O.O
-Jiuling's gone home to Yangcheng at the Fang estate. Ning family going crazy like a soap opera tantrum lol, only Yunzhao is cool as a cucumber. Both Chengyu and Yunzhao plan on gently wooing Jiuling. These poor guys. Zhu Zan is the only guy who really seems to stick in her mind. She randomly thinks of him quite a lot.
-I forgot to mention, but Jiuli endlessly tries to get Lu Yunqi to let go of Princess Jiuling and leave Jiuling-as-Zhenzhen alone. It never works because he's a crazy yandere stalker at this point.
