Fake daughter, she is beautiful and sassy

Chapter 165 Never seen before
Lan Yin took the pen, took off the cap, and casually took her monthly math test paper away from Professor Mu Lin's hand.

After that, she put the test paper on the gray-black marble coffee table in front of her, leaned over and wrote a line of formula in the blank space of the last exercise in the test paper.

After finishing writing, she put the pen cap back on again, put the test paper and pen on the table, and pushed them back in the direction of Professor Mu together——

After finishing these, Lan Yin immediately got up from the sofa.

He left a word in a calm tone.

"Okay, you can understand after reading this. I still have to go to class, so let's go first."

Seeing Lan Yin's actions, Principal Chen got up subconsciously to send her out.

And Professor Mullin picked up the test paper from the gray-black marble coffee table intently, staring at the formula that the girl just left behind—

A formula he had never seen before!
A few seconds later, Professor Mullin's eyes lit up!
In this simple formula, he seemed to see something.

But specifically, calculations are needed to determine the correctness of this line of formulas.

Thinking of this, he immediately took out a pocket notebook the size of half a palm from the inside pocket of his suit jacket.

Then he picked up the pen, and started to write something in the notebook with a look of obsession——

Professor Mullin wrote faster and faster. He seemed to have discovered some miracle of truth. Gradually, the whole person's condition became a little crazy!
When Principal Chen came back after delivering his benefactor, what he saw was the gray-haired Professor Mu, with a dignified expression and ecstasy, as if in a state of madness, constantly writing and calculating in his little notebook...

Originally, Principal Chen planned to discuss the mathematical formula left by his benefactor with this professor Mu who came from afar.

But now, after a moment of stupefaction, Principal Chen realized that Professor Mu probably wouldn't talk to him until he figured out the mathematical calculation method in his mind...

So he had no choice but to sit aside and wait for the mathematics professor from Dongming University to complete the calculation.

...

In school, a morning passed quickly.

After school at noon, Lan Yin didn't plan to have lunch in the school cafeteria as before, but left the school and went back to her villa.

Now that she has the nutritious meals carefully prepared by Chef Jin every day, she will naturally not settle for the second best to eat in the big canteen.

Anyway, the residence is not far from the school, and you can reach the place just by turning a corner when you go out.

Lan Yin had just left the school. In the principal's office, after a whole morning of calculations, Professor Mu Lin finally confirmed that the calculation formula written by the third year student in Ningcheng No. [-] Middle School was correct!
Moreover, he used this formula to solve the so-called world-class math problem in a whole morning!
This result was something Professor Mu Lin never thought about before coming to Ningcheng No. [-] Middle School!
Besides being excited by the current results, he is even more eager to meet that 17-year-old high school girl—Lan Yin!
But he searched for the classroom of Class [-], Grade [-], only to find that the girl had already left school...

At this moment, Professor Mu Lin felt that he seemed to have experienced what it means to not think about food and tea, and live like a year!
He never dreamed before that his mood would appear because of a teenage girl——

Not because of feelings, but because of a heart that loves to learn!

He is in his forties, but because of the appearance of a young girl, he regained his original intention of actively studying——
