Inside the ballroom.

A group of students were silent.

Everyone, including the few male students, was stunned by Lu Sheng's speech.

Although such a statement is no matter which direction you look for loopholes, there is no problem. But how weird it sounds.

Ruolin fell silent, feeling that her heart was beating violently with the teacher's words just now.

An inexplicable unwillingness slowly permeated from the depths of my heart.

Yes, she was not reconciled. Why do you have to go back to get married and have children as soon as you graduate, and then live an arranged life for the rest of your life?

Why should she, as a woman, be assigned marriage by the family.

Not only her, but also the rest of the people slowly poured out a trace of indignation from the depths of their hearts.

"So, how do we get the strength? and ask the guru to teach me. Ruolin stood up and couldn't suppress the emotion on her face and said in a deep voice.

Lu Sheng smiled, feeling that the psychological guidance had worked, and continued again.

"This is a great gift to you when I finally graduate. ”

He turned around, picked up the leather bag that had been on the chair behind him, and pulled out a stack of notes that had been prepared from it.

Each of these slips of paper is filled with dense patterns of various characters. The address is also stained with a hint of silver handwriting on the end.

"Take this, if you still want to believe me after graduation, then in three days, bring this note and pick up something at the address above. ”

He assigned the slips of paper to each trainee individually.

To everyone's surprise, the way he sent out the notes separately was also different.

Lu Sheng pinched all the notes, his hand tightened and loosened, and after opening it, the original notes suddenly turned into small white paper balls.

He sprinkled lightly.

With a bang, all the paper balls fell on the table like small balls, and then rolled around.

Each ball rolls precisely in front of each student.

"This...!?" Ruolin was stunned by this miraculous hand. This requires not only great eyesight and hands, but also extremely precise control.

She raised her head and stared at Lu Sheng carefully, this was the first time she had seen a math tutor in more than three years.

Picking up the note, she opened it and looked at it, just one glance, she felt slightly dizzy.

On the slip of paper, a long list of numbers was written in front of the address, nothing else, just mathematical numbers.

"Once you have the note, you can recite the numbers on it. You can find something wonderful, unusual. Lu Sheng smiled, "This is mathematics, great mathematics." As long as you diligently recite the numbers every day, it won't be long before your body and mind will be harmonized.

And the last three digits of this number are also the dates that each of you corresponds to. On that date, find a place to burn the note, mix it in the water and drink it, and you will get what you have always dreamed of. ”

"This is mathematics, incredibly powerful mathematics!" he opened his arms again. "If you work hard, it will give you everything. ”

"Really...."

"How does the mentor feel a little unreliable..."

"I'm afraid I have some kind of illness?"

The eyes of the students present gradually became a little distrustful. Mathematics is a very good subject, but the problem is that the tutor in front of me seems to be engaged in mathematics as theology, and it is a bit unreliable no matter how you listen to it.

Lu Sheng had already anticipated this problem.

He picked up a ball of paper.

"What kind of power do you think you need to have to free yourself from the shackles of your family, so that you can have enough freedom and choice?"

"It's enough to be able to survive on your own without relying on your family and still live well. A girl replied with a clear mind.

"Very well answered. Lu Sheng nodded approvingly.

"Not only that, but we also need enough strength to fight the family. Otherwise, they wouldn't want to see us leave, because each of us has poured family expectations and effort into us. It is an iron law that there must be a return for effort. Another girl said in a deep voice.

"It's profound. Lu Sheng nodded and smiled.

"There is also a strong enough inner will, otherwise the moral condemnation of society alone is enough for us to not support it. The third girl spoke again.

"Very good, very good. Lu Sheng smiled and nodded. "That's why I'm giving you this note. Because, it's the key. ”

"Key?" Ruolin clenched the paper ball thoughtfully.

"A key to be able to contact all of you. The smile on Lu Sheng's face was even worse.

What he did on this paper ball is beyond the comprehension of these ordinary girls.

For this plan, the barbecue chef not far away had already been hypnotized by him, and as long as he left this banquet hall, he would remember nothing.

This conspiracy lasted for more than three hours, and no one knew what they were doing inside except for the members involved.

The only thing that outsiders know is that the students who graduated from this level formed an organization of the Sisters of Steel not long after they left the academy.

Although the organization is very loose and the members do not communicate at all, after each student returns to the family, he still lives as before, without any abnormal state.

But only they know.

From that day on, everyone, it was different....

Indeed, as the Guru said, He gave a key, a key that held them all together.

~~~~~~~~~~~

~~~~~~~~~~~

months later.

Rumors of the Sisterhood of Steel are spreading in White Mist City.

They are rumored to be philanthropic and active in developing members, but they have little contact with each other. It's as if after the development members join, they leave the other party alone.

The Holy See, which originally managed and supervised everything, thought that this new type of organization only existed in the Academy, but later unexpectedly discovered that this Sisterhood of Steel had quickly developed into an elite woman from the outside. Even some ordinary nuns of the Holy See were joined.

Originally, they thought that this might be some cult member secretly planning some evil art sacrifice. However, after sending secret agents into it to eavesdrop, the Holy See did not find any problems. The members of this organization actually pulled people to join and then left it alone.

Over time, the Sisters of Steel grew in size. They advocate for the advancement of women in society and greater social respect. Gain the right to have your own childbearing.

These do not have any conflict with the Holy See, but have some contradictions with the traditional aristocracy, but they are not big.

Gradually, all eyes let their guard down.

But no one knows that there is an amazing secret hidden inside the Iron Sisterhood.

Crash.

Lu Sheng flipped through the pages of the book in his hand, his eyes calmly fixed on the content on it, but his mind was not on reading the book at all.

In his mind, he could clearly perceive a huge network of communication, constantly exchanging information at some invisible level.

"Today Viscount Monta left his horse farm and went to Sives. ”

"The Fourteenth Prince broke his leg during the course of his teaching, and he may be disabled. ”

"Did anyone find the book I wanted? The prize money remains the same, it's still a thousand gold dollars. ”

"Sisters, I found something interesting in the old books of my family. Everyone can share and take a look. ”

Different sounds and images, along with the senses of smell, touch and taste, are transmitted to this illusory network. It's like a package of files that all the Sisters of Steel members who link to the network are free to download.

And all those who download can get the exact same experience of the five senses as the uploader.

This is Math.com.

A vast network that connects all the members of the Sisters of Steel and shares information.

In addition to sharing information, it also has an extremely terrifying effect.

That's reading memory.

There are twenty core members of the Iron Sisterhood, and these twenty people have the greatest authority, and they are free to look through the memories of any member who joins the Sisterhood. and select available knowledge to upload and store for everyone to use.

That's why the Sisters of Steel are crazy about developing members. With each member developed, the more information and knowledge they are likely to acquire.

As the core of the mentor who built this mathematical network, Lu Sheng didn't have to do anything, just maintain the security of the network.

And the root of supporting this network is actually his mutated mercury blood.

The paper ball he gave to each core member was stained with a trace of mercury blood in his body.

Now he is like a super powerful server, everyone's information will flow into him, and the information and knowledge packages uploaded and downloaded are actually stored in him.

The members of the Sisters of Steel were only skeptical at first, but once they actually joined, no one wanted to leave.

In addition to the vague hypnotic power that looms in this mathematical web, it is more about the desire to peep into other people's privacy, and the desire to pursue knowledge and power.

Lu Sheng didn't need to instruct them on the cult's sacrificial summoning methods at all, and as more and more members joined, some people had already discovered a little clue about this.

Lu Sheng slowly closed the book and looked at the math net, where there was something that had just been uploaded by a girl.

The moment he closed his eyes, a large dark space suddenly appeared in front of him, filled with rows of various yellow wood bookshelves, on which all kinds of books were constantly increasing and decreasing.

One of them is the key information that has just been highlighted by the members.

"Sisters, this thing I found is very important, be sure to ask the mentor to help you put it on top. Let all see. I suspect there's a secret side of the world that we don't know! All of us, perhaps, live in a fragile boat that could be turned upside down at any moment, and we don't know it!"

The person who discovered the bag was a nineteen-year-old girl named Erin.

Lu Sheng glanced at it, as a server, he only scanned the contents of this knowledge package in an instant.

This is about Erin's discovery of a strange and dangerous black leather book in her underground library.

Lu Sheng only looked at it a little, and knew that the book should be a real case book used by the cult to summon unknown beings a long time ago.

That is, the little book that cultists use to sum up the lessons of failure.

It's full of taboos, regulations, and a few revised summoning formations and summoning spells.

It is very informative.

However, he is now just an ordinary math tutor, and he must continue to play this role well. so as not to attract the attention and vigilance of others.

"What is this?" he asked.

Soon Erin replied.

"I was having afternoon tea, and my father was on my side, so I asked the tutor to wait for ten minutes. ”

"No problem. ”
