Nalanxian

The aristocratic Lu family has produced a joke, a beautiful one, but a joke nonetheless. The daughter they have been rearing all this while turns out to be an imposter! With the real heiress returning to take her rightful place, everyone is eager to know the outcome of the imposter...
Will she be able to survive in poverty after living a life of riches?
Having just transmigrated, Huo Yao imagines that this experience will be pretty interesting. However, imagination and reality are always so different! 
Dad: "Daughter! Take this black card. It has no limit! Use it freely."
Mom: "My dear Yao Yao! If you don't like this jewelry, I'll get them to change it immediately."
Huo Yao: "…"
Weren't they supposed to be poor and ordinary? What is with this hidden lavish behavior?
Her eldest brother, an investment company's CEO: "Sis, inherit my company!"
Her second brother, a top lawyer: "Whoever dares slander my sis will face the full brunt of the law!"
The third brother, an international genius doctor: "Bullying my sister? Should I display the prowess of my scalpel?"
Mysterious fourth brother: "My sis is the cutest!"
Huo Yao: "…"
What happened to being a good-for-nothing person who lives off her parents?
A top aristocrat secretly changes into his cheap clothes and drives his crappy old car to her. "Baby, my heart is yours. Why don't we get married to test if I'm telling the truth or not?"
Everyone who knows about it, doesn't dare say it out loud. 
All they can do is curse inwardly: "Bah! Keep acting! No one believes it!"

Transmigrated As the Fake Heiress

Since He Xiaoman and Lu Ziming had left, Lu Xia naturally had no reason to stay, so she found an excuse and left awkwardly as well.

After they left, the old lady quickly looked at Huo Yao and explained. "Yaoyao, I didn't tell them that you visited me at first because…"

Huo Yao handed over the glass of water to Yang Qiuhua and interrupted her calmly. "I get it. I'm not angry. You don't have to be so nervous."

Yang Qiuhua instantly felt relieved. She took a sip of water and realized that it was her usual medication. She could not help looking up at Huo Yao in surprise. "Did you go back to get my medicine?"

Huo Yao replied nonchalantly. "Mhm."

She pulled a chair over with her foot and sat down lazily before she continued. "Why haven't you been taking the medicine which I gave you?"

Isn't Min Yu Your Tutor?
