The Wind Blows in the Red Building, from Companion to Tutor

If you dream of entering a red building, the beginning is a dead end. There are tigers and wolves in front of you, but there is no ground to retreat from behind. Fortunately, I have the "Book of All Emotions" in my hand, which can record the seven emotions and six desires in the world and exchange them for thousands of heavenly powers! Start by becoming Jia Baoyu's companion. Jia Zheng's appreciation, Baoyu's trust, Daiyu's sorrow, Sister Feng's calculations... Even Xue Pan's hatred, Jia Huan's jealousy, are all Jiang Yun's steps to reach heaven! Lin Daiyu's tears don't need to be shed anymore? Why does Jia Tanchun's sail have to be far away? Why can't the verdict on Jinling's Twelve Hairpins be rewritten? This time, Jiang Yun will use [medical science] to eradicate her stubborn disease, use [strategy] to cut off the sail going south, and use [strength] to tell the world—— Instead of sitting back and watching the building collapse, why not change the fortune with your own hands!
