There are large gardens, small lakes, rows of three-story Balot-style buildings, and each school even has its own study and living areas.

There are also a large number of academic landscapes in the middle, such as the Aura Fountain that erupts chemical formulas, the short two-legged spirit creatures that can provide services to students, and the Geological Teleportation Station that can teleport in the school for land exchange.

People come and go, and they are all scholars.

Everyone or a few people sit around the lawn to debate, or read in the beautiful garden, or walk in groups to discuss their experiences.

The strong academic atmosphere makes it like a scholar's utopia, and the beauty is not like the world.

Liu Fei is like a hillbilly who has come to the future from ancient times, and he feels new to everything.

The environment is not even comparable to the previous university.

He originally thought that Hangzhou Normal University, which was only second-rate, was probably no different from Salted Fish University in his previous life.

When he came, he knew he was wrong.

In today's era of population explosion, everyone who can be admitted to university is a scholarly genius, especially after advancing to the extraordinary, it is a broad road.

It's a fool to mess around in college.

Liu Fei followed the map all the way and finally saw the famous formula avenue of the Department of Mathematics of Hangzhou Normal University.

On both sides of the avenue is planted an out-of-space species called the Tree of Truth, a huge tree with a straight trunk and a canopy that shades the sun, often covering a considerable area of the sky with a single tree.

It is able to absorb aura and is especially close to mathematics.

Therefore, the leaves of the Tree of Truth planted near the Department of Mathematics emitted a vague green spiritual mist, and occasionally one or two mathematical formula symbols fell to the ground as if they were actually ripe, making a clear sound.

Walking underneath, from time to time being smashed on the head by the naughty aura formula, the coolness with a bit of warmth in the feeling is very intoxicating.

Liu Fei lingered reluctantly for a long time before entering the building of the mathematics department.

Chang Shuhuai's friend is a professor at Hangzhou Normal University and a doctorate-level scholar.

When Liu Fei called, the other party was busy, so he said that he would let his students receive him.

Liu Fei doesn't matter, whoever comes is the same.

After waiting at the door of the building for about five minutes, there was the sound of rushing footsteps behind me.

Liu Fei looked back and was embarrassed.

I bumped into my loved ones.

The other party was more embarrassed than him, and he stood on the spot and couldn't say a word.

In the end, Liu Fei was thick-skinned enough, and said hello with a smile: "What, hello." ”

"Not so good. Li Qiangpi didn't smile.

He's very irritable now, and this is a big deal, and this thing is chasing the school directly.

Do you think he's not ashamed enough?

Liu Fei smiled dryly: "Senior, I'm here to borrow a book from Director Tong." ”

"I know. Li Qiang was expressionless: "I have a library card, tell me if I need anything, I'll get it." ”

A high school student would come to college to borrow a book?

Li Qiang's face was very ugly, and he thought that Liu Fei had come to see his jokes.

Li Qiang took Liu Fei's book list.

“……”

"You want all these books?"

"Yes, yes. ”

Li Qiang didn't want to deal with Liu Fei, so he turned around and walked towards the library with Liu Fei.

But halfway through, he couldn't help it: "Who are you borrowing books for?"

"Myself. Liu Fei said shyly: "Recently, the textbooks in high school have been completed, and there is not much pressure on the college entrance examination, so I want to take a look at the university in advance, purely as a pre-homework." ”

GodTM is not too stressed! GodTM prepares for homework!

Lao Tzu was tired and tired back then, and you told Lao Tzu that there was not much pressure when you took the university exam!

The aura of aura on Li Qiang's arms flashed and disappeared, and aura continued to gush out.

What are you doing with your own mouth? What are you doing when you have nothing to do with that chance to pretend to be a comparison?

I want to hit someone now!

Liu Fei next to him was surprised: "Senior, your aura is leaking! How many days does your aura feel uncomfortable every month?"

Syllable!

The hard marble slabs under Li Qiang's feet cracked.

……

The library of Hangzhou Normal University is much larger than that of Zhenhua High School, and there are hundreds of study rooms and laboratories in it alone.

Li Qiang and Liu Fei also mixed in without a library card.

Li Qiang pulled his face and pulled out three books from the math area.

"I can only borrow three copies at a time, and you can come back to me after reading them. ”

"Only three?"

Liu Fei frowned slightly.

It's not easy to come once, and it's a waste of time to read these three books.

"Just three?"

Li Qiang sneered: "Just these three books are enough for you to see the wilderness, do you really think that the university is so simple?"

Liu Fei chirped, for the sake of the other party being his relatives, he didn't have the same knowledge as him.

"Can I read here?"

"Whatever. Li Qiang was too lazy to talk nonsense, the order he got from Director Tong was to borrow books, and he didn't care about anything else.

Liu Fei didn't say anything polite to Li Qiang, he simply took out a pen and paper from his backpack, and then found a place to sit nearby.

Opening the thick "Advanced Algebra", Liu Fei briefly looked through the table of contents and found that a few things still had some impressions.

After the upgrading of mathematics, Liu Fei's talent has been greatly improved, and with his profound high school knowledge as the foundation, Liu Fei found that the content is not difficult to understand.

It can even correspond to what you learned in your previous life.

Remove those things that are associated with Reiki.

Advanced algebra is essentially the study of matrix theory and linear space and linear mapping theory. Knowledge points such as sets, vectors, and vector spaces are covered in high school.

Of course, these are the most basic, and there are still many things to learn if you want to go deeper and deeper step by step.

Liu Fei has formed a habit of entering the state very quickly.

Within a few minutes, he forgot that there was another Li Qiang beside him.

Scholars advanced to have a hall of knowledge that could accommodate aura, so most places in the university did not have the existence of aura arrays, and Liu Fei could not absorb aura through study.

In fact, with his current level of spiritual transformation in the Perfection Realm, there is nothing to absorb.

Li Qiang was angry and had nothing to do.

Director Tong specially explained that he must take care of this high school student, and there is no other way except to accompany him.

Li Qiang's dislike for Liu Fei intensified again.

Liu Fei's learning speed is not slow, but in the case of no guidance, there are still some areas where the understanding is still not thorough.

He wanted to save up the question and go back to ask Teacher Wang Enzhang, but after delaying his efforts back and forth, Liu Fei simply looked for his relatives with a thick face.

"Brother, I don't know about this place, you tell me about it. ”

Li Qiang didn't raise his eyelids: "No matter." ”

Liu Fei sighed: "Then I'll call Director Tong." ”

Your uncle's!

Li Qiang dragged the textbook and said angrily: "Where do you not understand!"

Liu Fei smiled: "The existence of extremely linear independent groups, does any vector group have extremely linear independent groups?"

Li Qiang pondered: "Of course, according to the definition, we first select a vector in the vector group, and then add a vector to it, whether the vector group composed of these two vectors is linear or not. As long as the number of columns is finite, it is possible to find a group of vectors containing a small rain or a maximally linear independent group equal to it. ”

Liu Fei suddenly realized: "Understood! Assuming that the expression method is not unique, then there are two groups of K1K2K3 that are not exactly the same in K, and then subtracting the two formulas L1L2 can prove that the table method is unique." ”

Li Qiang nodded, this method was concise, and he was about to speak when he suddenly felt that something was wrong.

"You just learned this?" Li Qiang said in a lost voice.
