I Con the First Emperor of Qin with My Plane-Hopping System

Note: This is a parallel universe, not historical fiction. It's a comedy, so be sure to check the content warnings. Also, the heroine's memories are mixed up. It's not that the author doesn't know any better. Gu Qingning is trying out a newly released online simulation game when she and her game account transmigrate together. Her garden-style hotel turns into a two-story starter house, and the System tells her she has to reach the highest level to unlock a space-time tunnel back to the modern world. Fine. All she has to do is make money, earn experience, and level up. She's a pro! But can someone tell her why she transmigrated to the Han dynasty, more than two thousand years in the past? Wasn't the game set in a fictional dynasty? How did it suddenly become a real dynasty? Still... maybe this isn't so bad. She might even be able to bury some gold in the past for her future self to find. Besides, running a hotel with water, electricity, and internet in ancient times, where you can't get anything you need... Wait, an inn. That's basically cheating! Even with just a one-story house, she could run a five-star inn. She already has it all figured out. People in ancient times have never seen the convenience and fancy gadgets of a modern hotel. And since the house appeared out of nowhere, she can easily pass herself off as an immortal. Who wouldn't want to stay at an immortal's inn? Gu Qingning has a good plan, but she never anticipated that transmigrating through time would scramble her memories. As a result, her secret identity as an immortal is always on the verge of being exposed. The first world: Emperor Wu of Han's era Liu Che: Immortal, do I have any hope of attaining immortality in the future? Gu Qingning shakes her head, at a loss for words. You'll live extravagantly and indulge in wine and women. In the end, they'll wear you down, and you'll die of a stroke while having sex. Liu Che: !!! Wei Qing: I want to know if I'll have a peaceful end. Gu Qingning sighs. You'll launch a surprise attack on Longcheng, recover the Hetao and Shuofang regions, defeat the Xiongnu Chanyu, and be named Grand Marshal. But the civil officials will grow suspicious of you and push you aside. The emperor will strip you of your position and send you away from Chang'an. You'll die of grief the following year. Wei Qing turns pale. Huo Qubing, standing nearby, feels uneasy and asks Gu Qingning, What about me? Gu Qingning: You'll be celebrated as a great general for your victories at Langjuxu and Hanhai. At twenty-three, an old injury will force you to switch from military service to civil office. You'll write military treatises such as Ten Arguments for the Recovery of the Central Plains and Nine Discussions, as well as many timeless, much-loved lines of poetry. But you won't be happy. Your greatest wish is to go to battle and kill the enemy, not become a poet who pours his feelings into verse. Huo Qubing stares at her, dumbfounded. What happens to them afterward Liu Che begins exercising restraint. He gives up alcohol and women, sends away most of the women in his harem, and devotes himself to governing, determined to become a great emperor remembered for all time. Wei Qing earns even greater favor from Liu Che and becomes more humble. Liu Che repeatedly suppresses the civil officials, who suffer miserably. They're innocent! They really haven't been making things difficult for the general. Huo Qubing: I really don't know what Ten Arguments for the Recovery of the Central Plains or Nine Discussions are. The second world: Qin Shi Huang's era Ying Zheng: May I ask, Immortal, how long will the Great Qin dynasty last? Gu Qingning: It will fall in the second generation. Ying Zheng is struck as if by lightning. Fall in the second generation? How could that be? He conquered all six states. Who will destroy Qin? Or is Fusu so utterly unfit that he cannot shoulder the burden of ruling the realm? So shocked that he cannot hold back, Qin Shi Huang asks her what he is wondering. Gu Qingning: The one who succeeds you won't be your eldest son, Fusu. Qin Shi Huang is even more shocked. If not Fusu, then who? Gu Qingning looks at Ying Zheng sympathetically. Hu Hai will murder his father and brothers. After taking the throne, he'll live in extravagant luxury and exploit the people, imposing heavy taxes and levies until the populace is filled with resentment... Qin Shi Huang: !!! The third world: Emperor Taizong of Tang's era Gu Qingning looks at Li Shimin, hesitating. How can you have such a wonderful empress and still insist on taking your son's wife as a concubine? You're over fifty, with one foot in the grave, and still so lustful. Li Shimin freezes on the spot. ...I didn't. I wouldn't. ...There are many more worlds, but I won't introduce them all.

The heroine's brainwaves were affected when she transmigrated, scrambling her memories and leading her to mix things up. 3. What fanfiction doesn't have out-of-character moments?
