After the first pillar of black incense burned out, Jiang He finally put down his pen, and the scientific question of why the sun rises in the east and sets in the west has finally been roughly answered, and Jiang He elaborated in detail in terms of geographical structure and seasonal changes. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoWhy is there a rise in the east and a fall in the west, why is there a spring, summer, autumn and winter, and then he also carefully depicted the analytical diagram under the answer with his own painting.

Jiang He looked at his test paper with satisfaction, and then looked at the second pillar of white incense that had been lit, time was pressing, he picked up the pen and continued to answer the question without resting, about the history of why Taizong stationed troops, Jiang He could only obtain information from all kinds of official history and wild outlines, and then analyze the geographical location and the climatic conditions at that time.

The more Jiang He wrote, the more focused he became, only the lines of the pen on the volume and the complete font of the presentation, in a trance, Jiang He seemed to be back in front of the bookshelf in his room at this moment, and the bookshelf in front of him was placed one after another neatly arranged books, "History of the Southern Kingdom", "The Fifteenth Year of the New Calendar", "Tiannan Travels"... In his mind, Jiang He stepped forward gently, and then opened them one by one, and the brush in his hand excerpted and quoted them one by one, and then added his own perception and analysis.

The sky outside the hospital is bright, a round of scorching sun hangs in the middle, the cicadas chirp endlessly, disturbing people's hearts, occasionally there is a cough in the examination room, and only the slight friction sound of scratching ears and cheeks and brushstrokes on the paper can be heard, Jiang He's palms are a little sweaty, he wiped his trouser leg and then continued to answer the question.

There were many officers and soldiers standing outside the examination room, holding halberds to maintain order, and the streets outside the courtyard were already crowded with people, some shaking fans to watch the excitement and waiting for the end of the examination, some pushing carts to sell some dried fruits and snacks, and some private school teachers wearing long robes, waiting for the candidates to come out and ask about the content of the examination as soon as possible.

All of them were loudly discussing the questions and guessing the students who might pass the exam.

。

At this moment, in the examination and supervision office of the Protectorate Academy, several old men with long beards were sitting in the room, with some books and documents and a few teas in front of them.

"Isn't the exam too difficult this time?" said an old man in a sackcloth shirt as he took a sip of tea in front of him.

The fat old man sitting across from him nodded in agreement, "It's a bit over-the-top, and we may not be able to answer it at our level." ”

"It doesn't matter, the memorization questions in the front and the calculation problems in the back have reduced the difficulty. The other old man put the file in his hand on the table and said.

The old man in the sackcloth shirt stood up and put his hands behind his back, pacing back and forth in the room, the fat old man poured tea in front of him, looked at the people dangling in front of him and said angrily: "Old Qin, don't go, I get dizzy." ”

The old man had to stop and stand in front of the house, the door of the front yard was closed, and even the few windows were tightly sealed, only the light came in through the cracks between the windows, and the room was still lit with oil lamps, and it looked a little dim.

"How long will it take for the exam papers to arrive?" the old man sitting at the table asked softly, looking up at the closed courtyard door.

"An hour or so. ”

There was silence in the room, and no one spoke for a long time, save for the occasional sound of turning over the file and the rustling of tea poured into a cup.

"I don't know what the dean is going to do. Old Qin sighed leisurely, not knowing what he was thinking.

Several respected old gentlemen in the room were silent for a while, this year's exam papers have always been written by the Ministry of Rites and the Protectorate together, but this year's questions were written by the dean himself, if they didn't get the reference answers first, maybe they really couldn't answer these questions. According to the assessment standards, only those who have passed the lowest assessment line can fill in the list.

According to the rules of previous years, the files of the top three should be sent to the Ministry of Rites for review, if no one in the top three this year gets a high score, it will not be a loss of the reputation of the Protectorate, and the most important thing is that it may also touch the nerves of some people in the end, because some people's children are also in the list of exams this time.

There was another silent silence, no one answered his words, I only hope that we can see a few outstanding talents this year, after all, this is a question personally made by the president of the Protectorate, and few people dare to question it.

。

Jiang He finished answering the remaining essay questions, took a long breath, and then put the pen down in the bucket behind him, scooped a scoop of water and washed his face. At this time, many candidates had already handed in their papers and went out, and the examination room was gloomy and gloomy and sighed again and again. The questions in this exam were somewhat unexpected.

The streets outside the exam room were already loudly discussed, and the people responsible for collecting exam questions and compiling preparation books were also talking to each other. Even the vendors selling sugar gourds joined in the discussion with great interest.

"This time the essay question was extremely difficult, and I had no way to write it, so I had to give up. One of the candidates said dejectedly.

"Not to mention the essay questions, the questions and answers that follow make me rack my brains. ”

"Hey, I heard that this time it may be the question of the dean of the Protectorate himself. ”

"It's no wonder.,It's not at all what the difficulty of previous years should be.。。 ”

The streets were noisy, and the soldiers had to push the crowd back a little further so as not to disturb the candidates who were still taking the exams.

Jiang He washed his face, felt a lot more energetic, came to the table and sat down again, and flipped through the questions behind.

There is only one arithmetic question and one quiz question at the end. Jiang He read the arithmetic problem first, and found it very interesting.

"Everyone in the world knows that Li Qiubai likes to drink, one day he walks on the street, carries a pot to buy wine, doubles when he meets the store, sees a bucket of flowers, meets the store and flowers, drinks the wine in the pot, how much wine is there?"

This is a backward calculation problem, as long as it is reversed, the original number can be calculated, but if you honestly reverse the calculation five times, the calculation process will be more complicated.

Jiang He had to come up with the solution of the unknown number equation that he knew, that is, a simple one-dimensional equation, and after thinking for a while, he took a pen and wrote on the paper: "Suppose the original unknown pot of wine, the first time you meet the store, you will double the unknown pot, and the first time you meet the flower, you will have twice the unknown pot minus one... ”

"From the above, it can be deduced that there were originally thirty-one pots of wine. ”

Jiang He knew that maybe these so-called equation unknowns and equations were too difficult for these examiners to understand, so Jiang He carefully recorded and explained the algorithm process and analysis principles one by one, and I don't know if they could understand it in the end, Jiang He thought to himself that he had written it so thoroughly, if they didn't understand it, then there was no way.

When the last incense stick was lit, there were few candidates left in the examination room where Jiang He was located, and only a few candidates were still sitting, but most of them had painful expressions and didn't know where to go, and even the invigilators were a little ignorant.

And at this moment, Jiang He stared at the last question, and he was also a little confused.

"The rain between heaven and earth, falling from the sky, and rising from the earth, the firewood of the husband is scorching, turning into green ash, and the fertile land makes the seedlings grow, so why is it that the end is changed back and forth?"

Jiang He read it carefully, and then realized more and more that the person who wrote the question was a real scientific maniac, not to mention the various discussions and questions on geography and astronomy before, this last question alone was enough.

This is a question about materialist philosophy, asking the reason for the reincarnation of life and death between heaven and earth, Jiang He knows that he can't explain it from the perspective of metaphysics, life is life, death is death, there is no legend of heaven and earth and there is no reincarnation of ghosts and ghosts, the world always likes to make up some gods and ghosts, just because of the unknown and the fear of death, because they have no knowledge of the scientific truth contained in it, because of the unknown and fear, because of fear and the production of goblins and ghosts. But what makes Jiang He very puzzled is that this planet, which is completely in line with the common sense of science, will have a kind of heaven and earth vitality, and this kind of thing also has the terrifying power of the gods.

Regarding the cycle of rain and the withering of plants and trees, Jiang He really wanted to capitalize with a thick brush on the last exam paper: This is a physical phenomenon, can you not worry about it!

But he still didn't have the courage to lift the pen, yes, he really didn't know how to explain the scientific truth that water came from heaven and returned to heaven so that it happened to us. Just like Jiang He has never been able to understand the theorem of conservation of energy, the disappearance of one energy has turned into another form, if you tell the common people in this world that there are no ghosts and ghosts in this world, after you die, but you don't drink Meng Po soup, maybe you will be scolded to death as a nervous heretic.

It wasn't until the third pillar of yellow incense burned halfway that Jiang He finally woke up from his contemplation, lifted his pen and dipped it in ink, and then slowly wrote: "Life is extremely dead, death is extremely life, dead wood welcomes spring, cold snow turns water, but its essence is undiminished... ”

He tried his best to use concise and contemporary views to elaborate, sometimes science is like this, discovery does not mean that it will be accepted, but Jiang He believes that since the Protectorate dares to question and dare to ask questions, it means that such a scientific process will not go too far, and the ideas he puts forward will not be too alien.

The more Jiang He wrote, the more curious and excited he became, what kind of place was the Protectorate, and what kind of person was the dean, who was called a god-like dean.

And in such a scientific world that completely conforms to the laws of physics, will there be creatures that he has really never seen and things that even violate the laws of physics, Jiang He does not know and is not sure, because the universe is so vast.

Jiang He didn't know that there was another thing, today's exam was actually more like an academic discussion about science and society across space. One of the participants in the discussion was Jiang He and the other thousands of candidates sitting in this examination room, and on the other side, the old man who was sitting on the highest back hill of the Protectorate at the moment, with a pot of wine and a pot of broth in front of him.

The revered president of the ----- Protectorate.
