At eight o'clock in the evening, the sky was full of stars and moons.

The nightlife of Hangcheng County has just begun, and the rich people have come out to start the lights and dances.

Watching the noble gentlemen in the city running around in horse-drawn carriages, the dancers of the ballroom stood at the door and dressed sultry to attract guests.

Li Zhen walked around the edge of the city with a backpack and a pair of gloves, looking for something to make a living.

There are still a lot of garbage bins, and these are places where you can 'hide treasures'. But there are also quite a lot of competitors. There are also many orphans who have no parents like Li Zhen, begging everywhere to pick up garbage to make a living.

Iron is a very valuable waste product. A pound of iron can be sold for a price of nine coins. And usually, only twenty coins are needed, which is enough for Li Zhen to live for a month. One hundred yuan is enough for Li Zhen to teach in a public high school for a semester. Over the years, he has been studying for himself, and he has not been seen dropping out of school for a day, which shows that Li Zhen's attitude towards work is still very diligent.

Since childhood, he has been determined to be a pillar of the revival of the empire, and since he was a child, like most teenagers, he dreamed of one day being able to enter Imperial College from high school and become a high-profile college student. Get more further education, walk in the forefront of science in this world, and become a pillar of the Kyushu Empire.

Therefore, Li Zhen has always attached great importance to learning knowledge.

Unfortunately, the quality of teaching in Hangcheng County, the only public high school, is too poor.

The last time I graduated from Hangcheng County and was able to be admitted to university was 20 years ago......

No way, there are only two universities in the entire Kyushu Empire, one is Imperial College in the capital Nakashu. One is Fuxing University in Dongzhou.

There are 100 million or 200 million people in Kyushu, and hundreds of thousands of students take the college entrance examination each term. And the two universities only admit a few thousand people each year. It's really a thousand troops crossing a single-plank bridge.

The college entrance examination in 10,000 years is more difficult than 10,000 years ago.

10,000 years ago, people didn't have much ambition to contribute to the country and the world.

And in 10,000 years, everyone dreams of becoming a pillar of the country, a scientist and a revivalist who can be famous for eternity.

It's a great honor if you can become a 'scientist, an inventor, a revivalist' that the imperial power recognizes." Your hometown will be proud of you, and the people in your hometown will straighten their waists when they go out, and they are proud to say that there is a ...... in their place

Li Zhen vowed that his life's desire was to become the person who could make the empire proud of him.

Of course, the most important thing at the moment is to become a college entrance examination candidate and be able to have a qualification to take the college entrance examination.

Because of the fact that there are more monks and less porridge, the college entrance examination environment in the Kyushu Empire is relatively harsh, and most merchants make profits from it. You need money to get through the layers of relationships.

After calculating an account, I want to become a college entrance examination candidate from a fresh graduate and sit in that examination hall. Costs at least one gold coin. And this gold coin is equivalent to 1,000 coins of the banknote denomination......

Leisurely, Li Zhen walked to the largest garbage transfer station in the entire Hangcheng County, which is called 'Qiantang Valley', which is a very deep and narrow valley. Some people say that in ancient times there was a river called Qiantang River, and no one knew whether it was true or not.

Stepping on the stinking ground of Qiantang Valley, Li Zhen's eyes became vicious, eagerly searching every inch of the surface to find anything valuable.

In a few moments, the back basket was almost full.

Looking at the time, it was already ten o'clock at night, and Li Zhen couldn't care about looking for a 'way to make money' anymore. Carrying the bag on his back, he quickly ran to the recycling station.

He had more important things, and every night he had to go to bed before eleven o'clock and dream of her......

"I'm lucky today, you can find an iron cage that a rich family has a pet for. Oh, seven coins. ”

The female boss of the scrapyard rummaged through the change of seven coins.

Li Zhen smiled and nodded: "Thank you." ”

"Hey."

"How?"

"Do you really want to take the college entrance exam?"

"I'm definitely going to participate."

Li Zhen laughed.

The female boss frowned: "Forget it." ”

"Why?"

"To be eligible to be a candidate, you need at least more than 1,000 Kyushu coins. With this money, you can live a good life and don't need to pick up garbage every day to make a living. You can start a small business and be able to marry a daughter-in-law in the future. And this more than 1,000 coins is only a qualification to become a candidate. What if it doesn't make the list? What if you didn't get in? Those who don't get into the exam are worthless. In fact, hundreds of thousands of people take the college entrance examination every year, and hundreds of thousands of people fail every year...... More than 1,000 coins, it will be wasted. ”

Li Zhen was silent for a moment: "I have to take the test." ”

"Is it worth it to be so persistent? With a fee of more than 1,000 coins, hundreds of thousands of candidates compete with you. More than 1,000 coins is not important for a well-to-do family. But for you, it's three years of picking up garbage and scrap in exchange. That's just a reference qualification...... Alas. The last time Hangcheng County could not produce people who could be admitted to university was 20 years ago. Never again. ”

"I can!"

"Why do you have to insist on going to college? In fact, more graduates take the exam, and they don't expect to be able to pass at all, they just need a layer of qualifications. In the future, their parents will arrange better jobs for them, after all, they have taken the college entrance examination. And you? You don't have parents, you don't have a backer, and it's useless for you to ask for this qualification. Why bother? ”

"I can get in. Definitely. ”

"Hehe, the college entrance examination will start in more than ten days, don't say anything else, do you have enough money?"

Li Zhen was silent for a long time, didn't speak, and left.

The female boss of the scrapyard shook her head and sighed: "Devilish man." Picking up three years of waste and cutting back on food and clothing, just to make a splash? I don't believe you can. Because in the entire Hangcheng County, there has been no one who has been admitted for 20 years. ”

“……”

When I returned to my shack, it was already half past ten. It was dark.

It's still noisy outside, rich people are eating supper, and it's noisy.

Picking up the seven coins from selling scrap, he walked to the very center of the house, dug a pit in the sandy ground, and pulled out an iron box from it.

Flipping open the iron box, there is a stack of plastic banknotes lying neatly inside.

This is the common currency of the Kyushu Empire, called 'Kyushu Coin'. The material is made of plastic, which is easier to preserve in wind-blown sand, but it is extremely difficult to imitate because the process was designed by scientists at Imperial College using ancient technology.

Sitting cross-legged on the ground, he counted all the money again, and sighed: "Seven hundred and twenty coins." Alas, I saved such a little in three years. ”

And not discouraged.

There are still ten days, and you can think of some ways to your heart's content. You can also ask her if there is any way to pay for the college entrance examination.

There were no beds, no furniture, just a wall of old books.

Li Zhen lay on the sandy ground, covered his body with a layer of plastic to keep out the cold, and quickly fell asleep......

He fell asleep, fell asleep in this world.

In another world, but awake.

Once again, I came to a familiar and unfamiliar space, where it was dark on all sides, and there was only a waning moon in the sky, but I couldn't see what kind of scenery was around me.

Li Zhen sat on the ground casually, looking at the waning moon, in a trance, waiting.

No matter how late it is, she'll always come......

Another under the stars.

In an upscale neighborhood, a girl in pink pajamas is flipping through a book under a lamp.

'Jingle Bells'

The alarm went off, the girl's eyes narrowed into crescent moons, and an expectant smile appeared on her face: "It's eleven o'clock again, it's time to go to bed again." ”

"Dad, I'm sleeping."

"You're about to take the college entrance exam, review it again."

"Sleepy."

"No, I blew all the cows out to your uncle and aunt, saying that you will definitely be admitted to Peking University. Don't let me down. ”

"Mom, I'm really sleepy, you take care of your husband."

"Alas, let the child sleep when she is tired."

"Hmph, then you sleep, but you are not allowed to play with your phone."

"No, it won't."

“……”

Since that strange feeling a year ago, eleven o'clock every night has become the appointed time. He and she both fell in love with going to bed before eleven o'clock.

Until half past eleven, Li Zhen was a little anxious and waiting, and she finally appeared in this dark space.

"Really!"

"To!"

The two met. They stared at each other, and after a moment, laughed at each other.

He didn't remember her last name, only that her name was true. She didn't remember his last name, only that she called Zhi.

"What did you do today?"

"I'm going to tell my teachers and classmates what you told me today. Saying that the world was destroyed by nuclear fission, many people applauded me. ”

Zhi frowned: "I guessed." After all, we are all in an era of peace here, and the Third World War has not begun, and I don't know when it will start. But guess, it will definitely be a nuclear bomb or something. ”

"Anyway, I think it's pretty reliable."

"Come on, Zhen-san, I'm going to give you math tuition tonight. Where did you learn last night? ”

Li Zhen recalled for a moment and said, "The relationship between functions and calculus. ”

"Yes, yes, calculus. Alas, I'm not very proficient either. I'm actually bad at math, and I'm only here to teach you. I didn't expect ...... I studied mathematics for you, and I will be the first in the school in the math test now. What makes sense. ”

"Hehe, it's a pity that you can't bring your ancient books to dreams, otherwise I will teach myself."

"Phew, what an ancient era. You are only in ancient times, we are a modern scientific and technological civilization, okay? ”

"We are only modern in 10,000 years."

"Sister, you're more than 10,000 years younger than me."

“……”

"Now, what does the cannonball depend on when it comes out of the barrel, and the range it travels away from the original power?"

Li Zhen frowned, and said uncertainly: "Angle? ”

"Yes, at what angle can the range reach the farthest?"

"No...... I don't know. ”

"Remember, 45 degrees. This is an application of calculus, which uses functions to find unknown conditions under known conditions...... Advanced mathematics is important and will never be a simple number game. You're going to have to use them in all sorts of areas. By the way, after 10,000 years, mathematics is really lost? ”

"It can't be said to be lost. The use of mathematics in daily life has always been there, but no one has studied mathematics as thoroughly as you did 10,000 years ago. There is no higher mathematics. ”

"Ah, how happy the students must be in 10,000 years......"

“……”

Unhappy? Happiness?

Li Zhen smiled bitterly.

The time spent in dreams is the shortest, but also the most pleasant.

He can see his beloved, and he can also absorb knowledge like a bloodsucking worm.

He could never have imagined that 10,000 years ago, people would study various disciplines to the extreme. It's unimaginable.

And the subject level in 10,000 years is described as "elementary school level" in the words of the end.

In the past year, Li Zhen has learned too much in his dreams that far exceeds the knowledge of this era, so he is eager to be admitted to Imperial College. Only by entering the Imperial Institute of Technology can his knowledge be valued and he can make a great contribution to the revival of the Kyushu Empire.

He often teased him, saying that he had the spirit of a revolutionary pioneer.

Li Zhen didn't know what a revolutionary pioneer was, he only knew that everyone in this world had the same thoughts as himself. It's just that I'm more urgent than they are......

Wandering in the ocean of knowledge, time passed imperceptibly, very briefly.

Suddenly, a strong feeling of palpitations came, and this feeling was not unfamiliar to Li Zhen. It's the tearing feeling at the end of the dream.

"It's going to be over."

until he suddenly spoke.

Li Zhen was a little disappointed: "Is it so fast?" ”

As soon as the words fell, the body that I saw began to fade and was about to dissipate. Li Zhen lowered his head, and his body was also fading, as if he was being torn apart by some mysterious force.

The two looked at each other, warm and affectionate.

As soon as their hearts moved, the two suddenly shouted to each other in tacit understanding: "What's your surname!" ”

“……”

A dream of a year, at the end of each night it is said goodbye in such a way. Every time, I forget to ask the other person's last name, and every time I can only remember it at the moment of separation.

A few times they knew each other.

But after two days, it will be forgotten again.

Dreams are always easy to forget......
