Because of the huge impact of glider experiments, this game, which used to look like a toy, suddenly became a hot topic in the Academy of Sciences.

At the request of many craftsmen and craftsmen of the Academy of Sciences, Chen Xu specially organized a simple lecture on aerodynamics in the Academy of Engineering.

But this brought more problems, that is, about the interaction and relationship between the formation of air currents and topography, Chen Xu had to add a few lectures on the relationship between climate and topography.

"The formation of air flow is very complex, temperature, topography, sunlight have a very big impact on it, atmospheric flow is actually the same as the principle of water, water is flowing from a high place to a place, this principle I have talked about before, because of gravity, the higher the water pressure, the higher the water pressure, the air also has air pressure, from the place of high pressure to the place of low pressure, this will form the wind, the southern climate is slightly warm and humid, the sunshine is sufficient, the surface water evaporation is strong, it will form a large enough air pressure, This pressure will expand inland, and form a monsoon carrying a large amount of water vapor, this airflow encounters the blockage of the Taiyi Mountains, the airflow continues to rise, the temperature continues to decrease, and finally the airflow condenses into clouds and mists into water droplets to fall, forming a large amount of precipitation at the southern foot of Taiyi Mountain, making the south rainfall abundant, and also because of the blocking of the Taiyi Mountains, the warm and humid airflow can not penetrate into the interior of the Central Plains in large quantities, resulting in a relatively dry and rainless large number of large river basins, and the same northwest because of the Yinshan Mountains and plateaus again blocked, water vapor decreases again, As a result, the northwest is dry and rainless, and not only the plant varieties are reduced, but the vegetation is also relatively sparse......"

The principle of rainwater formation is very clear to primary school students in later generations, but in this era, it is very incomprehensible, the Spring and Autumn Period and the Warring States Period for the study of natural science has just begun to sprout, and it is far from forming a consensus, as for the systematic theory of atmospheric motion is even more impossible.

No one knows where the clouds and mist in the sky come from, so when the wind and rain are blowing, they think that the gods and demons are manipulating.

Legend has it that the wind master Yu Bo is two demon gods who can manipulate the wind and rain, and Chi You also defeated the Yellow Emperor several times with the help of these two immortals.

Later, it became the work of the dragon king to travel through the clouds and spread the rain, so in the drought season, pray to the rain god and the dragon king, and the dragon king and the rain god will also kowtow to the dragon king and the rain god when the rain is in trouble.

In this age of ghost worship, all inexplicable natural imagination will be associated with ghosts and gods.

There are gods in spring, summer, autumn and winter, there are gods in day and night, there are gods in the wind and rain, even cooking and sleeping have gods, in short, ghosts and gods are everywhere, and the people's awe of nature is transformed into the worship of various gods, offering melons and fruits and three animals to pray for the blessings of various gods.

But Chen Xu's statement completely broke the theory of ghosts and gods blowing wind and rain.

Therefore, the craftsmen and craftsmen and students of the Academy of Sciences and the Faculty of Engineering are very confused about these changes.

If the wind and rain are not under the control of the gods, then what is the significance of the existence of the wind god and the rain god?

"Science, not to study ghosts and gods, but to use an intuitive means to analyze and understand the way of nature, for those who do not understand, do not easily throw it to the gods and demons, but to think carefully about the reasons, ask more why, such as why the two copper balls will fall at the same time, why the moving pulley will save effort, etc., these seem to be incomprehensible, but there are traceable internal reasons, I suggest that you look at the Mojia theory in the future, especially for the Mojing to study carefully, because Mozi is a great scientist, It is to use the principles of science to analyze nature, and the Mohist theory is also widely used in life, the simplest is the scale, which uses Mozi's principle of balance on the strength arm......"

For the noisy situation in class, Chen Xu doesn't have much energy to explain some things carefully, because there are too many things to explain, and every sentence needs to be explained, this is the limitation of the times, a person's mind is half a step ahead is a genius, if you are too much first, you are a fairy and demon.

Therefore, these can only be suppressed by Chen Xu's identity as a disciple of the Immortal Family, otherwise if it is an ordinary person who talks about these theories, it is estimated that the emperor will put them in the oil pot and slowly fry them on the outside and tender on the inside, and he will be relieved to completely blow up the demon in his body.

From April to May, from early summer to midsummer, the weather is getting hotter and hotter, and Chen Xu's life has become extremely fulfilling in the ordinary.

In order to solve some scientific interpretation problems, so that the craftsmen and students of the Academy of Sciences and the School of Engineering can more intuitively understand that science is not a new school, so Chen Xu specially asked the bookstore to sort out all Mozi's theories on science, revise them and print them for publication.

Therefore, the newly compiled "Book of Ink" became the first Jingyi to be officially published among the hundred schools, and together with Zhang Cang's "Nine Chapters of Arithmetic" and Chen Xu's "Simple Geometry", it became a subject that students in the College of Engineering must study.

For the publication of the "Book of Ink", it once set off a violent wave among the court and the disciples of the hundred schools, and even the emperor was alarmed, and then specially invited Chen Xu into the palace to learn more about Chen Xu's thoughts, and then did not say anything.

The Book of Ink does not promote Mozi's strict religious organizational structure, nor does it promote the Mohist political idea of equality of all people, nor does it promote the Mohist concept of governing the country, but purely collects and sorts out the Mohist understanding and cognition of mathematics, geometry, optics and force, which is actually a complete scientific enlightenment course.

Moreover, because of the publication of the Book of Ink and the propaganda of newspapers, some disciples of the Mo family hidden all over the country began to come to Xianyang with a cautious mood and applied for jobs at the Academy of Sciences and the School of Engineering, so that Chen Xu received several scholars who were proficient in mechanical manufacturing and rich in theory.

For these scholars, Chen Xu arranged them to serve in the Academy of Sciences and the School of Engineering, and at the same time asked these Mohist disciples to abandon the struggle with Confucian Legalists in governing the country as much as possible, concentrate on scientific research, and strive to use their knowledge to seek a great future for their future.

In fact, the Mo family at this time had already fallen apart.

Most of the ink disciples have disappeared from the people, and what remains are characters who hide their identities as craftsmen, who have no idea of governing the country or even subverting Great Qin, just ordinary people who have pure research on mechanical science.

The uproar over the publication of the Book of Ink quickly subsided after a while.

Because of the current Great Qin, the Mo family actually has no foundation for existence or the leader of the Mo family has long been missing, and the Mo family disciples scattered all over the country have long been like orphans without fathers and mothers.

The construction of Dongfang Road is still in full swing, and every day all kinds of news are sent to the Academy of Sciences like snowflakes, and Zhao Qing arranges for someone to sort it out and send it to the palace for the emperor to read.

After nearly five months of construction, the large and small bridges along the Dongfang Road have been successfully built and can start to pass through cars and horses, which greatly speeds up the transportation of cement, and even the caravans from east to west have been greatly facilitated, and the transportation of goods is more lively and busy.

Several hills that were turned and straightened were also blown up with gunpowder, and five hills were blown open, one of which was a tunnel, which is still in the follow-up cleaning and reinforcement, and the entire Dongfang Road also saved nearly 300 miles, saving a lot of money and time for the merchants who contracted these sections.

At the same time, relying on Luoyang, Xinzheng, Daliang, Puyang, Linzi five cities based on the logistics market and more than 10 planned service stations along the way are also under rapid construction, the local counties in accordance with the Oriental Road General Administration of planning and the order of the three provinces and six ministries, each in the Oriental Road along the large area of land, obtained these commercial real estate development qualifications of the businessmen have already begun to start the construction of the Oriental Road at the beginning of the construction, now the Oriental Road project is basically more than half, these commercial development has basically entered the end, In particular, many service stations have begun to wait for investment business, foot houses, post houses, food houses, business houses, repair stations, and even Quyuan tea houses have begun to slowly put into operation, and began to provide services for business travelers along the road in advance.

The sooner you start operating, the sooner you start recovering your capital.

This is the common idea of all contractors.

The dismantling of the Northeast Army was carried out in an orderly manner under the decision of the three provinces and six departments, and half of the half a year stipulated by the emperor had passed, and most of the dismantled army had begun to be disbanded and resettled.

One of the most concerning and eye-catching is that the preparations for the police station under the Criminal Department have gradually taken shape.

The officials of the county and county police departments across the country have basically all been arranged in place, and as long as the criminal department slowly deploys the personnel and horses according to the military merits in the Northwest Army, another powerful national organization will soon appear throughout the country, and once more than 100,000 police officers are formed as a violent organization to maintain civil order, they will completely stifle the chaos of civil turmoil, as long as the court is not chaotic, the country of Daqin will soon be stabilized, and the people of the six countries and the chaotic people with bad intentions will be completely monitored and suppressed.

According to Chen Xu's original suggestion, the Criminal Department specially set up a special police force of 3,000 people, which was specifically responsible for the security of Dongfang Dao, and established more than 20 police stations based on logistics markets and service stations.

The minimum configuration of the service station is a police force of 50 people, the highest leadership rank is equivalent to the deputy director of the county, Wujue is above the fifth level, the subordinate institutions and the county-level police station structure is almost the same, the five large logistics markets are each equipped with 300 people, the top leader is equivalent to the deputy director rank, Wujue is above the tenth level, the subordinate institutions and the county police department structure is the same, these highway police directly belong to the criminal department under the sole leadership, not under the jurisdiction of the local county, can independently investigate and arrest cases, In order to prevent the highway police and local county officials from colluding with each other because of interests, bullying passing merchants, embezzling goods, money, etc.

Of course, these things are inevitable, but as long as the officials of the supervision ministry are in place, good operation can still be guaranteed.

What's more, it is impossible to have officials who oppress the people, this is a problem that can never be solved by human beings, power determines thought and status, and it is even more impossible to put an end to this kind of thing in this era when the barbarians are so wild that the nobles do not treat the commoners as human beings.

The system is the only means to restrict and supervise the occurrence of such things.

The only means by which such a system can be properly enforced is the law.

But at the moment, it is impossible for Chen Xu's eyes to pay attention to these aspects.

Because there are too many laws that Great Qin needs to change.
