Immortality: Starting with a grave, I'm invincible when burying corpses.

In Jiuyu, where the pace of life is relatively slow, student life is mostly carefree. Students don't have to bear too many burdens in life, nor do they have to face too much filth.

If you also encounter a gentle and refined teacher and have a classmate who is enthusiastic about creating surprises, your daily school life will be even more colorful.

Sui'an Academy is just like that, with the gentle teacher Bai Ling and Li Yin who occasionally creates little surprises.

Unlike sects that emphasize lineage and have complicated rules, and unlike other academies that emphasize formalities, Sui'an Academy's "rules" are simply no rules.

Although the nine students address each other as senior brothers and junior sisters, they are actually more like classmates studying under the same roof than a group sharing the same honor and disgrace as a master and disciple.

Nine people from different backgrounds, with different experiences and different personalities, came together by chance and came to "Sui'an Academy" to study under Mu An and Bai Ling.

There is not much self-interest or scheming involved; it is more about the chance encounter that led to this friendship among classmates.

As for Mu An and Bai Ling, they had no intention of taking on disciples; they only considered these nine people as students attending their lectures.

It was precisely this attitude of the two that gradually made the nine students in the academy accustomed to life there.

At first, some people from prominent families were not used to it and felt that such behavior violated etiquette and did not conform to the order of seniority and hierarchy.

But as Li Yin repeatedly "stirred things up," these formalities were forgotten.

Years later, everyone at "Sui'an Academy" has mastered a skillful set of "reconnaissance and counter-reconnaissance" techniques.

Enjoy the flowers in spring, play in the water in summer, climb mountains in autumn, and watch the snow in winter...

In this life, Li Yin lived the life she had always longed for, a life that only existed in ancient texts.

In her previous life, Li Yin lived in a technologically advanced world, so advanced that the entire world was covered by machines, and complex code maintained the operation of the entire world.

Everyone lives within a predetermined framework, following a pre-designed program.

In the world where Li Yin once lived, there was not much difference between people; they were more like a group of NPCs acting according to a predetermined path.

Because before each person is born, their genes are rewritten, moving towards the most perfect template during the gestation process.

Every child born has extremely high intelligence, perfect appearance, and is as precise as a machine.

Thanks to highly advanced technology, in Liyin's world, people do not need to reproduce in the traditional way, nor do they need to consider any issues in the reproductive process; all procedures can be completed by machines.

Even a baby's gender can be altered using technology; whether it's a boy or a girl depends entirely on the guardian's wishes.

For example, before coming to the Nine Realms, Li Yin did not actually have a clear gender. This was because his or her guardian did not want an ordinary child. Rather than having a normal offspring, they wanted to try something new.

Against this backdrop, Li Yin was born, with an identity that was neither male nor female.

In fact, Li Yin herself didn't care much about the issue of gender. In the world she lived in before, people like her were not uncommon. After seeing so many, she naturally got used to it.

The real reason she hated the world was much simpler.

The world is unchanging, and there is not a glimmer of hope in sight.

Because of the advanced technology, in the world where Li Yin once lived, humans had already been domesticated by machines during the development process.

From birth to death, everything for each person follows the code designed by their predecessors, proceeding according to a fixed program without any changes.

It's both a blessing and a curse; some people like it, and some people hate it.

In such a world, there will always be some "outliers".

Li Yin is one of them. Compared to an ordinary life, she prefers to study ancient books, study philosophy, and challenge herself with excitement and pushing her limits.

During a trek through Tiangong City, Li Yin was unexpectedly struck by lightning and inexplicably found herself in the Nine Realms, her body changing from that of a twenty-seven-year-old to that of an eleven-year-old.

Even after experiencing such a bizarre event, Li Yin did not feel afraid; instead, she became even more excited.

In Li Yin's mind at the time, with her intelligence, even if her body shrank and she lived in a different world, she could still live a good life.

Later, due to her complete lack of common sense and extreme hunger, Li Yin directly stole food from others on the street.

After a struggle, Li Yin was caught by the arriving constables and taken to the government office.

After a long and arduous ordeal, Li Yin, covered in wounds, was thrown into a corner of the street, where she awaited death amidst hunger, cold, and numb pain.

It was at this time that Li Yin met Bai Ling, the adorable and lovable older sister in her eyes.

With just two meat buns, Bai Ling successfully lured Li Yin away, creating a big problem where Li Yin always called her "Sister Bai".

If Li Yin hadn't been so young at the time, and hadn't looked so pitiful covered in wounds, Bai Ling felt she would never have taken Li Yin back.

But since it has already happened, Bai Ling will not really regret it, nor will she really drive Li Yin away.

In the midst of their playful bickering, the events that followed unfolded.

……

What Bai Ling didn't know was that in Li Yin's eyes, she, as a teacher, actually had no authority at all.

In Li Yin's eyes, Bai Ling was somewhat naive and silly. She was always a bit silly and didn't even know how to take care of herself, making her the perfect person to tease.

If it weren't for concerns about the impact, Li Yin felt she could tease Bai Ling three times a day.

Unfortunately, for too many reasons, Li Yin didn't dare to actually do it, so she could only use her misplaced energy on her other junior brothers and sisters.

Because she has read many books, Li Yin is very good at perceiving other people's emotions.

Her past interests allowed her to easily maintain a balance, teasing her juniors while also acting as a mentor at appropriate times.

Li Yin genuinely enjoys this playful and carefree life.

……

As for Mu An, Li Yin said that this person was a bit scary.

Even now, Li Yin can't forget those colorful eyes.

The feeling of being looked at by those eyes was so terrifying that Li Yin had many nightmares afterward.

Because she was too afraid, even though Mu An allowed Li Yin to learn the Five Elements, she did not follow Mu An to learn it.

It was after that meeting with Mu An that Bai Ling took Li Yin under her wing and her attitude towards Li Yin changed a lot. She no longer corrected Li Yin's way of calling her "Sister Bai" as before.

Although there is no clear evidence, Li Yin felt that Bai Ling probably knew her real age and some general information about her.
