Azi, born into the renowned Tang family of the Western Region, hails from an ancient lineage that has persisted since the Qian Empire, spanning over a hundred years. The Tang family encompasses more than a hundred smaller families and is most famous for its expertise in hidden weapons and mechanical devices.
As a descendant of the Tang family, Azi began learning these unique skills from a young age. Compared to her peers, Azi exhibited extraordinary talent, mastering nearly all the skills in less than ten years. According to family tradition, Azhi was expected to take on a significant role in the Tang family upon reaching adulthood, guiding future generations in preserving these ancient arts.
Unfortunately, Azi herself had no interest in this path. Instead of the family's traditional arts, she was more captivated by modern trends and fashion. Leaving behind a letter saying, "I'm off to play in CangLin City!", she left her hometown for the new metropolis and eventually joined WeiShi through various coincidences.
In her daily life, Azi is always a trendsetter. Whether it's her clothing or daily habits, she consistently exudes a unique and distinctive style.

As an ancient family from the Western Region, the Tang family boasts many long-standing traditions, with the "Four Arts of Tang" being one of them. These Four Arts—"Swallow Step", "Flying Dart", "Condensed Poison", and "Ingenious Mechanism"—are unique skills that the Tang family has refined over generations. According to family tradition, every member begins learning these skills from an early age. When Azi was just a little girl, she became a focal point for many instructors due to her study of the Four Arts. It wasn't because she lacked talent and needed extra help. On the contrary, Azi was quick-witted and nimble, running up and down the mansion from a young age. Whether it was running along the eaves or mastering hidden weapons, she could grasp the basics within a few days of practice. Before she was even of age, she had already mastered the first three skills. Even the "Ingenious Mechanism", which many adults found challenging, was something she handled with ease by the age of sixteen. What truly gave her tutors headaches, however, was Azi's ingenuity. "Zi Tang, how many times have I told you not to bring these strange things into the practice field!" "Teacher, this isn't something strange. Today's lesson is 'How to Escape Using Hidden Weapons', and this is the hidden weapon I prepared for the practice class." "Are you saying flashbangs count as hidden weapons too?" "I believe it does. According to 'Flying Dart', a hidden weapon should be 'lightweight, easy to use, and can be hidden in the sleeve; hence, it is called a dart.' When it comes to evading pursuit, this flashbang is far more effective than any needle or caltrop."
…
"Speaking of which, 'Condensed Poison' means making poison through chemical reactions. In that case, flashbangs are also a kind of 'Condensed Poison', since they work through the chemical reaction between magnesium powder and oxidizers."\

…
"Teacher, aren't drones also 'Ingenious Mechanisms'? They're similar to the mechanical arrangements described in the books, driven by mechanical devices, just with more complex designs."
…
"I protest, why isn't a sniper rifle considered 'Swallow Step'? No matter how skilled one is, walking will always leave traces. Isn't solving the problem from thousands of meters away without moving a step supposed to be true 'swallow passing without a trace'?"At some point, Azi's understanding of the Four Arts of the Tang Family far exceeded what her tutors taught, and she regarded modern technology and tactical equipment as part of the Four Arts. Whenever the name of this unique student is mentioned, instructors either remain silent or show a face full of worry. Only a few younger instructors, after pondering for a while, comment with a mix of laughter and helplessness: "Gifted".

Even back in the Tang family, Azi was a well-known social media expert. Whether it was online shopping discounts or posting techniques, she could talk for hours about anything related to the internet.
At that time, Azi had already set up various accounts on many platforms and forums to share her daily life. Although most of her content was about the scenery of the Shu Mountains and Tang family fun, her daily updates and lively writing style garnered her a lot of attention.
This gradually cultivated her habit of constantly updating her social media accounts. While still at home, Azi would listen to her parents and tutors, only checking her phone and updating her status after class or meals. But after moving to CangLin City with less supervision, Azi fully unleashed herself.

Going out shopping, she updates her status. Resting at home, she updates her status.
If the weather is sunny and she feels cheerful, she updates her status.
If the weather is gloomy and she feels down, she updates her status to vent.
If the weather is neither sunny nor gloomy, then she updates her status to guess whether it will be sunny or rainy later!

From fashion trends and internet hotspots to brushing her teeth or having a snack, everything became a topic for Azi's updates.
This habit made her particularly attentive to her follower count. Whenever she made new friends, she would invite them to follow her account immediately. When Azi joined WeiShi, she even included her social media handle in her introduction and was extremely enthusiastic during the newcomer welcome party, exchanging follows with almost all attendees.
After the party, many members of WeiShi began experiencing various strange phone-related phenomena.
Some found their phones buzzing incessantly from morning until night, with notifications of new updates waiting to be checked. Others saw their homepages flooded with promotions for seasonal perfumes, new desserts, and trendy clothes they'd never shown interest in. The most common issue was having their feeds filled with posts from a certain purple avatar account, disrupting their normal browsing experience.
Upon investigation, they all traced these issues back to the same social account:
"wHasAziGoneToBedEarlyTodayw".

To this day, WeiShi has a saying: "No matter how enthusiastic Azi gets, don't follow her account easily. If you must, make sure to enable 'Do Not Disturb' immediately."

"Azi, do you have any money-making tips?"
"You don't usually spend much. Why are you asking me this all of a sudden?"
Azi continued scrolling through her phone at a leisurely pace while listening to Xin's question.
"I saw a barbecue grill last week and wanted to buy it to try out. Qing suggested I get a part-time job, but every time we go out, I see you buying perfumes and nail polishes—all these expensive and fancy things. I wondered if you had any easier ways to make money."
"There are definitely many ways. For example, those perfumes and nail polishes are actually products I test for shops and promote on my social media. Not only do I get to use them for free, but they also pay me." "
"But these methods are too trendy and complicated to explain in a few words. For now, just stick with your part-time job... I have something to do this afternoon. I'll teach you more when I have time."

After parting ways with Xin, Azi did not head for the exit of the commercial street but walked into another shop once she confirmed that Xin wasn't following her.
She skillfully tied her hair up, changed into her uniform, and pinned her name tag to her chest. …
"Welcome to Meow Meow Café. What would you like to order?"
…
"These are our specialty drinks. You can get a 20% discount if you order two!"
"Wouldn't you like to try our seasonal desserts? There's a discount if you order now!"

Clearly, the real Azi wasn't as carefree as she appeared in front of Xin. To cover her expenses, simply relying on promotional gigs was not enough. Azi often had to work several part-time jobs simultaneously to barely make ends meet. This afternoon alone, Azi had already worked three different part-time jobs.
As for why she didn't tell Xin the truth, it was probably just for that small bit of pride... If her friends knew about her true situation, her carefully maintained trendy image would collapse.

"Oh, thank you so much, Azi! If it weren't for you, I would've been overwhelmed by my busyness! My mischievous daughter not only doesn't help with the shop but keeps spending money on all sorts of things... If only she were as obedient as you, Azi!"
Over time, Azi's frequent and outstanding work earned her a reputation as the "jack-of-all-trades" on the commercial street. Whenever there was a part-time job available, people would think of her first.
"By the way, Azi, there's one more thing. We have a new employee in the kitchen who is a bit impatient and is causing a mess. Could you help out?"
"No problem, I'll take care of it."
Such rescue missions were familiar to Azi. She walked into the kitchen and immediately started organizing.
"Aunt Wang has already briefed me on the situation. Since things are urgent, let's skip the introductions and get straight to work. I'll start with the preparation area in the back, and you start with the cleaning area. First, we need to..."
"Huh, Azi?!"
"You already know my name? Strangely, I don't remember mentioning it... Wait, that voice is—"
Following the familiar voice, Azi saw a familiar head of red hair and an equally surprised Xin.
…
Years later, every time she passed by that store, Azi would recall the afternoon she locked eyes with Xin, both wearing their café uniforms.
