At eight o'clock in the morning, Otogawa appeared at the library on time, full of food, and prepared enough brown sugar water, ready for a big battle today.

Before that, he went to the river to investigate, and after a night, the water ghost seemed to have been slain.

At least there are a lot fewer SWAT officers with real guns.

This efficiency, leverage.

As for the male classmate who died, the official version is that a Chinese alligator swam from the Yangtze River to the campus lake and river because of the spring flood, which caused the tragedy.

Even, many people saw the carcass of a crocodile that was significantly larger than the average Chinese alligator being pulled away.

Social stability is very important, national first-class rare protected animals or something, to hell!

Several speedboats were still roaming the water, and people could be seen throwing machines into the water from a distance to further confirm that there was no danger in the water.

Anyway, all truth is hidden under a white lie.

Panic, and did not appear.

Just as Yi Xiaochuan was continuing to read books in the library, several escort vehicles drove into a heavily guarded col in the provincial capital.

The car drove all the way into the tunnel, into the underground.

The searchlight shone through, the car stopped, and several agile soldiers jumped out of the car, and dragged a huge coffin-like sealed iron box out of the escort car.

More than a dozen people wearing pure white protective suits who couldn't see their faces clearly walked over, holding a device like a pesticide box in their hands, and sprayed at the black and heavy iron box, and the pungent gas immediately spread out.

The entire vehicle, including the people, was disinfected before stopping.

Then the white suits pushed the iron boxes into the interior of the mountain.

Went straight to a laboratory, and in a sealed environment, the iron box was opened......

Not a crocodile, but a hideous-looking humanoid, dead.

As for the cause of death, there are scorch marks on the body after being electrocuted, and there are wounds after being shot by bullets, but fatal wounds, it should be that the internal organs were shattered.

The impact of the grenade's explosion at the bottom of the water killed it directly, shattering its internal organs.

The humanoid, with stripped hair and webbed hands and feet, was apparently designed to swim better in the water, and in the bright light, the rough skin could be seen growing with fine, smooth scales.

Sharp nails grow on the webbed fingers, and the jagged teeth of a shark are extremely sharp.

These are supposed to be its weapons to kill.

Several men in hazmat suits dissected the humanoid in detail.

Then an old, slightly hoarse voice said, "Failed awakening...... Examine his DNA, find his pre-evolution DNA and compare it, we're busy, it's a new evolutionary direction......"

"Okay, Professor, I'll arrange ......," a young voice came out of the hazmat suit, and left the lab with the specimen.

"Old Criminal, don't you have to hand it over to a coastal laboratory? For example, the Second Research Institute in the Demon Capital? They seem to be more experienced in the study of the evolution of the water system. ”

"Hmph...... Do you think they're going to care about such an evolutionary failed subject? Giving them is a waste of electricity to occupy a freezer......"

"Okay! The non-mainstream that can manipulate the flames yesterday is really interesting, but ...... According to the analysis of big data, it seems that the chances of awakening recently are much higher! at least ten times that of the previous one......

"Alas, the cataclysm is coming! Although this is a blessing from heaven for us researchers, we really don't want this anomaly to continue. ”

"So, it's time for us to work harder. If we don't find a way to evolve safely, the whole country will be in chaos! We can't wait any longer, and we won't have time to wait any longer......

......

The elementary school girl with the cute hellokitty pink water cup didn't come today, but there was a long-legged beauty with amazing breasts sitting in the position of the elementary school girl in front of her, which made it difficult for Xiao Yi to calm down and read a book.

The eyes are always looking in that direction.

You know it's hot, but you're wearing too cool!

In the air conditioner, be careful of catching a cold!

When he wanted to change his position and concentrate on reading, he looked around and saw that it was already full.

"That's it, it's a test...... My little brother Yi is a man who wants to become a true scholar, how can you tempt him......"

It's impossible to settle down, the strength of the water ghost last night is obvious to all, thinking about hunting such a monster to get energy points, Brother Xiao Yi is a little intimidated.

After finishing the brushing of "Theory of Real Variable Functions" and "Theory of Complex Variable Functions", Otogawa gnawed on "Preliminary Lectures on Differential Geometry" without distraction.

This book "Elementary Lectures on Differential Geometry" is actually about Riemannian geometry, and the objects are also limited to curves and surfaces in three-dimensional Euclidean space. In essence, it is a preliminary study of Riemannian geometry, and the object of study is the Riemannian manifold, that is, the differential manifold with measurement.

Measurement is an important quality that distinguishes geometry from topology, but of course this is not absolute, after all, the field of geometry is too broad.

As for the connection with the higher algebra of the number of points, the number division is essentially calculus in a flat Euclidean space, and differential geometry is the calculus of uneven, curvature space and higher dimensional differential manifolds.

Yi Xiaochuan was immersed in it, and he felt that it was not difficult to learn, but there were a lot of formulas, and he suddenly felt that his arm was poked by something.

When I looked up, the long-legged beauty in front of me with amazing breasts was holding a pen in her hand, looking at herself embarrassedly.

"Classmate, I'm sorry to disturb me...... May I ask you a question?"

It was really annoying to be interrupted from studying, but Yi Xiaochuan nodded generously and said, "No problem, just ask!"

When interacting with people, appearance is very important.

Why didn't such a beautiful girl, with plenty of breasts and long legs, find me instead of looking for someone else?

That's not because her appearance can match her!

Explain the topic for such knowledgeable long legs, comfortable!

"Thank you. ”

The long legs whispered thank you, got up and took the pen and paper, and leaned over to Brother Xiaoyi's hand.

Shengsheng couldn't help but glance at the topic, and he was admitted to graduate school.

"Let me see...... Calculus, isn't it......"

Brother Xiao Yi thought for a while, this kind of postgraduate examination question, before a day, don't say that you can solve it, even if you give him the answer, you can't understand it, but before a minute has passed today, he has already spoken: "It's solved." ”

"Solved?"

The long legs looked surprised, looked at Brother Xiao Yi in disbelief, and said in his heart You haven't even started writing yet, how can you solve it.

Brother's strength is more than that!

Otogawa glanced at it, then picked up the pen and wrote down the process of solving the problem on scratch paper.

At this moment, a handsome guy over 1.8 meters walked over, went directly to the long legs, and said in a low voice: "Wenwen, you are here!"

Brother Xiao Yi glanced at the boy, isn't this the male classmate who was about to go into the water to save people last night!

What about these long legs?

It seems to be his girlfriend! Although I didn't pay attention to the dark light last night, but when I think about it, it was really her......

MMP, you have **, and you're still here to tease me?

After writing the problem-solving process and putting it on the corner of the table, Brother Xiao Yi smiled, and then picked up the "Differential Geometry" in front of him......

It took three days, and in the chatter of the dormitory manager every day, Xiao Yi finally finished reading "Partial Differential Equations", "Computational Methods", "Abstract Algebra", "Functional Analysis" and "Topology".

In fact, the later you go, the faster you learn, because the accumulation of knowledge is enough, and it is not difficult to learn, and the mathematics level has actually been improved to LV1 when you study "Functional Analysis", and Xiao Yi still finished reading the remaining "Fundamentals of Topology" in the library.

That's complete!

Brother has studied undergraduate mathematics thoroughly!

Are you going to apply for graduate school in the Department of Mathematics? Tsinghua University is still the legendary mecca of mathematics - Princeton?
