Qin Lu never thought that she would become a teacher one day, and she was still facing a group of young people about her age. Pen %Fun %Pavilion www.biquge.info but I have to say, the experience is quite fantastic.

What's even more amazing is the speed of Qin Lu's teaching.

It is almost impossible to teach the binary equation to the people of this era without changing it at all. After all, there are too many advanced factors involved, so in order to make it easier for these people to understand, Qin Lu completely changed the equation and taught them in another way.

Of course, the specific solution idea will not change. After solving the five questions, Qin Lu already had a general understanding of the content of the eighth test point, and the substitution and elimination of binary equations may not be suitable for other places, but for this exam, it is very suitable.

Even with such an unrecognizable mathematical algorithm formula that was changed by Qin Lu, the candidates still learned it at an astonishing speed. It took them less than an hour to master the basic method of solving the problem. The progress is faster, and it can even be used to calculate the questions of the previous exam in this way.

The road to teaching was going very smoothly, but Qin Lu was not happy at all. Because this result does not represent how well he teaches, but because these students of his mine are so smart.

Whether it is the merger of formulas or the assumption of unknowns, these people are almost all able to understand each other, and they can quickly draw inferences, this result makes Qin Lu, who has been ahead of them for more than a thousand years, feel very faceless, and only feel that he has met a bunch of fake ancients and become a fake teacher.

No matter how depressed Qin Lu was, Liang Yuan and others, who had learned the new algorithm, were more excited than one another. They were surprised to find that after using this algorithm to solve the problem, the time taken to complete a problem was suddenly shortened by nearly sixty percent.

In particular, the ten Arabic numerals, just a few simple strokes, can convert all the data in the question, which not only saves a lot of time, but also simplifies the estimation process, which is really a good thing to kill two birds with one stone.

"Okay, that's all I have to say, you can practice the rest of the time by yourself......"

Seeing that no one asked any more questions, they all began to lower their heads and calculate the exam questions, Qin Lu simply ended the class, asked the candidates standing next to him for paper and pencils, and finally wrote the questions.

"The pheasant rabbit is in the same cage, there are thirty-five heads on it, and there are ninety-four feet on the bottom.

"What is this?

Wu Wenchan learned the fastest, and when everyone was trying to calculate the test questions, she had already verified all of them, and she was staring at Qin Lu with a pair of beautiful eyes.

"It seems to be very interesting, why don't you let the slave family give it a try!"

"Take it, it was your ......"

Qin Lu smiled slightly, and handed over the pen, "This is a parting gift, solve it, and you will graduate." ”

……

At 3 p.m., near the eighth test center......

The scale of candidates has been strengthened invisibly, and taking advantage of the opportunity of the first wave of candidates being brushed down, more and more people have passed the first seven tests and come to the last test center in the field in Jiangnan.

The air at the scene was a little serious, and every contestant showed 100% strength, wanting to pass through here and reach Chang'an as quickly as possible.

But interestingly, among the many candidates here, there are three very different atmospheres.

One is the latecomers who have just arrived at the eighth test center, their emotions are obviously higher, but they have a sense of relief when they see so many people stuck here. Unlike the old men who have gone through a round of competition, they obviously don't know what kind of test awaits them.

The second type is the old man who has experienced a failure. Their faces were more solemn, and at the same time there was some well-concealed concern. These people know very well that the rules of the imperial examination competition give them only two chances, and if they are eliminated in the next game, they need to face more than just some pressure.

In this case, a group of people led by Wu Wenchan are particularly eye-catching. Completely different from the previous two waves of people, each of them had a slight smile on their faces, and the feeling of being in the chest made everyone look sideways, as if they were wondering why these people could be so careless in the face of such an important exam.

"Boom!"

After being quiet for a long time, the gong suddenly sounded, and everyone didn't care about observing the others, so they hurriedly collected their emotions and walked to the guards with their identity tickets.

To participate in the imperial examination, you need to register in advance, and each participant has a corresponding examination number, which is easy to manage.

Wu Wenchan watched the guards stamp a stamp on her own ticket, but her heart couldn't help but tighten. She knew what the seal represented, and once it appeared three times, the ticket was equivalent to an exit notice, and she had to leave, and there was no room for reversal.

"It's okay, I've learned a new algorithm, and this one will definitely pass without a hitch!"

While secretly cheering herself up in her heart, Wu Wenchan found her seat number and sat down quietly.

However, as soon as the exam paper was sent to her hand, Wu Wenchan couldn't help laughing.

It's still the same exam paper, but the content of the question has been completely changed, and the first question above is:

"Today there are pheasants and rabbits in the same cage, there are thirty-five heads on the top, and ninety-four feet on the bottom, ask the pheasants and rabbits how much they are?"

……

Qin Lu would never have known that a practice question that he casually threw out was crooked and collided with the imperial examination question. Now he is busy, sitting with two girls and happily calculating today's income.

"Five taels...... Ten taels...... Twenty...... Thirty ......"

Qin Baozhen volunteered to take on the heavy task of counting the silver, but as she counted it, her breathing was chaotic.

"Seventy, eighty...... Two hundred and ten taels, two hundred twenty-five taels...... Oh my God, we actually made two hundred and forty taels of silver today!"

"And these!" Qin Lu smiled and took out the change in his pocket, "To be correct, it should be two hundred and forty-five twenty-seven dollars!"

A pile of white flowers and silver piled together, not only did the two little girls shine brightly, but even Qin Lu himself was a little difficult to calm down.

The full two hundred and forty taels of silver, converted into RMB, is nearly 500,000.

Selling drugs doesn't make money!

"Woo~ I'm not dreaming, brother, come and pinch me......"

Qin Baozhen was so moved that she almost didn't cry, with tears in her eyes, she pulled Qin Lu's hand and pinched it on her face, it was obvious that she had earned too much today, and the little girl couldn't believe it was true.
