Gushan City is an industrial city. Steel production is 130,000 tons per year, and the second industrial revolution has been nearly 600 years old, and steel technology is so full of the status quo. In the eyes of Su Crow, who has the logic of earthlings, this is really lazy.

The 100,000-ton small steel plant is an energy-consuming industry that will be eliminated in the eighties of the last century by the standards of the earth. But the world is content with this technology. Moreover, in the accumulation of steel for hundreds of years, there are not many buildings with red bricks and green tiles in the city. High-rise buildings belong to the wealthy gentry.

The Bai family of scholars is one of the six major scholar families in Gushan City. The family has been based on the local history for 500 years, and it can be said that the family has a long history, controlling 10% of the county's farmland, and controlling the mines and docks.

The county Yin of Qingtian County, Gushan, is a member of this family.

The county office, a fifteen-story building, occupies the most prosperous part of the county, and black cars enter and exit every day, and in the garage of the county government there are also twenty armored cars, which have machine guns on them.

The huge gap between the rich and the poor makes the county often have people who do not want to be hungry in An'an. In the face of those Diao people who grabbed rice, the officials and lords of Hanshan had zero tolerance.

Together with the county government, the building surrounded by pavilions and water pavilions is Yueyang Library, a famous institution of higher learning in Gushan City. The winding river and the rotating wooden waterwheel make the school full of elegant artistic conception. Thirty-seven primary lineages are taught here, and it is one of the forty-three primary schools recognized by the Republic of Hanshan.

In the past 800 years, the legal lineage system has undergone another development, and the profession has begun to be subdivided. After a thousand years, the school system has long been a behemoth in society.

The profession of traditional physicians and mechanics has changed dramatically. Because of the bifurcation of science, industry and technology, there is also a bifurcation of occupations.

For example, between the two primary professions of physician and mechanic, there is now an additional junior profession of chemist. The Bai family is the person of this professional pedigree.

Chemist, who can advance to three median classes.

The first, the organic material master, can make grain, can control the synthesis of organic matter, which is an upgraded version of the grain maker.

The second type is the biologist. It can make grain, but it is decomposed by microorganisms, which will cause a lot of loss. Potions can be made. It is possible to modify the strains and viruses, and even the genetic code of rice seeds and bugs. Unlike orthodox medical priests in the physician economy, they are concentrated in the biological industry.

The third type, catalytician, compared to organic material engineer, this profession focuses on catalysts, organic material engineer mimic catalysis is only suitable for the temperature range of only 200 degrees, and catalytic engineers can manufacture catalysis suitable for high temperature and high pressure. High-energy explosives, as well as some demanding ceramic materials, are produced by this type of profession.

Among mechanics, there were two forks in the promotion of the median profession.

It is divided into a machinist for main machining and an electronic controller for main electronic control.

Subdividing so many professions is naturally the progress of society. At that time, Binghe was an all-rounder, so he could master advanced technology. However, the steam has only produced a spear and a genius for thousands of years, but development does not always depend on genius.

Now after classification, the threshold of technical personnel in each link has been lowered, and technology has been liberated. Marine steam turbines, which required a mid-level professional to build 800 years ago, can now be built with the cooperation of multiple lower-ranking professionals.

Today's social cooperation is much stronger than a thousand years ago, greatly weakening the traditional feudal family system, but only weakening, the influence of the family still exists.

Society is still rife with inequality. The school recruits outstanding talents for the middle class, while reserved places for the families.

Some children are born with a comfortable life and can enter the school without exams.

On the sixth floor of Yueyang Library, in Classroom No. 3.

"Bai Haoge, Bai Haoge!" A teacher shouted at a distracted boy in class.

The little boy who looked at the butterflies outside the window came back to his senses and looked at the math chips like the railings on the development screen, and he looked dazed.

The teacher tapped on the screen, "Come up and do the math." ”

Bai Haoge stepped forward nervously, and in his heart he shouted for salvation: "Xiao Hei, Xiao Hei, are you there?" Are you there? "—Little Black is Su Crow.

It all started two months ago, when Bai Haoge was sitting in the car, having a headache with his arithmetic homework.

However, just as he was troubled, another child's voice suddenly appeared in his ears. This timid voice suddenly said the answer to the arithmetic problem, but Bai Haoge couldn't see anyone by his side.

When normal people encounter this incident, they think that it is a ghost, and Bai Haoge also thinks so - the pen fairy manifests. In Bai Haoge's call, he saw a blurred light and shadow in his vision, and a very small person was in the palm of his hand. Then he took over Bai Haoge's vision, and some pictures of digital answers were drawn on the floor on Bai Haoge's vision.

When Bai Haoge wanted to continue asking for answers, the voice began to ask for a reward for discarding a box of dim sum wrapped in a rag outside the car.

Bai Haoge did this, and he didn't see who took the box of dim sum at that time. The box of chocolate treats and the tablecloth that wrapped the treats saved the crow's life at night.

Then, the two began to communicate. Su Crow helped Bai Haoge with his homework, and Bai Haoge was asked to place some offerings on the roof of the building from time to time, that is, some copper coins, and snack boxes and other things.

Out of curiosity, Bai Haoge secretly observed in the past two months and found that all the things he gave were taken away by the crows.

Equal communication: When the other party is willing, Su Yao can obtain the other party's perception information. The golden finger restriction is that once the other party is unwilling, the communication will immediately terminate with the other party's refusal.

When the other party has a high degree of trust in themselves, they can even replace the other party and control the other person's body, and the 'other party' here can be a human or an animal.

Now the animal that the crow likes to communicate with the most is the crow.

The crow is a social animal, and through communication, the crow group asks these crow groups to help them pass on the goods, and then the crow gives a reward, and the two sides are in partnership. But the death of a crow has caused a recent quarrel between the two to cooperate.

The two have now been cut off for two days. This is because the day before yesterday, Bai Haoge caught a crow and scared away a group of crows that could help Su crows communicate objects. The crow could not calm the restless crow and continued to retrieve the item.

And here, Su Ya looked for Bai Haoge to theorize, but Bai Haoge was very stubborn and unwilling to admit defeat, and the two quarreled. As Bai Haoge mentally resisted each other, Su Ya could not maintain equal communication with him in the past two days. The two sides are in a cold war.

And the reason for the Cold War, Bai Haoge was curious about who Su Crow was? But Su Crow will never let him know his true identity now.

The premise of equality is that the two sides cannot afford each other's material conditions, so equality occurs, and once the two sides can compare with each other in some aspects, then equality cannot be maintained. Now the gap between Su Ya and Bai Haoge's identities is too big.

At this time, in the slum, on the broken wall of an abandoned tiled house.

Su Ya was sitting on the wall, nibbling on the steamed buns he had just bought, and when he heard Bai Haoge calling, he exhaled in a low voice, paused and muttered: "I thought you could be angry for as long as you wanted, but you couldn't stand it in just two days." ”

Here, in the academy, Su Crow's light and shadow swished on Bai Haoge's shoulder, and the half-inch-tall villain form could only be seen by Bai Haoge.

Bai Haoge asked half-flatteringly: "Xiao Hei, Xiao Hei, hehe, what do you think of this problem?" ”

Su Crow sighed and said: "The problem is very simple, if you don't get distracted in class, you don't have to look for me, now open your arm control to me." ”

Bai Haoge was overjoyed in his heart, and immediately handed over the control of his arm to the pen fairy he thought of as a pen immortal.

Su Crow controlled Bai Haoge to hold a pen and list vertically on the development screen.

The premise of the Arabic vertical carry calculation method is to memorize the 99 multiplication table - the basic skills of Chinese primary school mathematics on the earth.

The basic mathematical skills of the people of the Eastern Continent in this world are based on the calculation method of arithmetic chips, and several arithmetic chips are placed together in a "well" shape vertically, and the numerical results are obtained by moving the arithmetic chips.

It's a very different style of math.

After Bai Haoge let go of the control of his hands, Su Crow was extremely proficient in vertical operation, of course, it was the wild way in the eyes of the teacher in the classroom. Bai Haoge was sweating profusely as he watched Su Yao control his handwriting on the development screen with a large number of incomprehensible vertical styles, feeling the teacher's backstabbing gaze in the back.

Thirty seconds later, Su Ya calculated the answer, checked it by the way, and then responded to him: "It's done." ”

In front of the blackboard, Bai Haoge asked in an uncertain tone in his heart, "Is it really right?" ”

Su Ya, who was asked by Bai Haoge like this, and now only has the ability to calculate at the age of six, also said with some self-doubt: "I'll do it again." ”

When Su Crow was ready to continue the calculation.

Teacher on the side: "Correct."

The teacher gave the correct affirmation, just when Bai Haoge was pardoned, bowed respectfully to the teacher, and then prepared to step down from the podium.

The teacher stared at him and said solemnly, "Our lesson is about arithmetic. Don't think that if you master mental arithmetic, you won't be able to listen to the class, I will test you in the next class. ”

Bai Haoge heard the teacher's criticism and returned to his seat with a sad face. muttered: "Unlucky, I have to take an exam." ”

After Bai Haoge felt sorry for himself, he found that the pen fairy did not respond to him.

He could only wipe his face and beg: "Xiao Hei, Xiao Hei, are you there?" Are you there? ”

Su Crow was helpless: "Yes, if you are willing to open your senses, I can help you cope with this exam." But you're going to help me find a new animal messenger. ”

Bai Haoge: "Do you still hate the crow?" It's stingy. I've got you all possessed. ”

Since the first exchange, Bai Haoge has treated Su Crow as a pen fairy.

Six kilometers away.

Su Crow, who was sitting on the wall, slapped the wall heavily and said angrily: "Don't treat me as a lonely ghost that no one wants, don't quibble if you make a mistake, my animal messenger is still afraid of you." At three o'clock this afternoon, a tanuki cat came to you at the entrance of the campus and helped me feed it.

Also, now you really need to listen to the lectures. Stop getting distracted in class. ”
